A large population of moths contains 35% white moths caused by the double recessive genotype, bb. What are all the allelic and genotypic frequencies for this population? (info on the equation also included)
Answer:
So after searching, I found the answer on a school tutor website :)
p = 0.41
q = 0.59
p^2 = 17%
q^2 = 35%
2pq = 48%
to check:
.41+.59=1 so thats correct
.17+.35+.48=1 this is correct too
i hope that helped :)
The answer is :
p = 0.41
q = zero.59
p^2 = 17%
q^2 = 35%
2pq = forty eight%
solution: 41+59=1
17+35+48=1
What are the frequencies of the alleles?Allele frequency refers to how not unusual an allele is in a populace. it is determined by counting how frequently the allele seems in the population then dividing by the whole quantity of copies of the gene. The gene pool of a population consists of all of the copies of all of the genes in that population.
What is the difference between allele and genotype frequency?Genotype frequency refers back to the variety of individuals with a given genotype divided with the aid of the whole quantity of people within the population while allele frequency refers back to the frequency of incidence or proportions of different alleles of a selected gene in a given population.

Which of the following reflects the relationship between the posterior and the anterior pituitary glands?A. Unlike the posterior pituitary, the anterior pituitary makes and releases its own hormones without input from the hypothalamus.B. One is always a little behind.C. The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.
Answer:
The correct answer is - option E.
Explanation:
The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.
On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.
Thus, the correct answer is option E.
What are the reactants and products for each step of photosynthesis and cellular respiration?

Which two parts of the cell are unique to plant cells?
Answer:
Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Explanation:
The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.
Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

The only accurate term that represents the characteristics of growth hormone is option c. production of insulin-like growth factors (IGFs).
Growth hormone (GH), also known as somatotropin, is a hormone secreted by the pituitary gland that plays a crucial role in stimulating growth and development in various tissues and organs. One of the primary actions of GH is to stimulate the production of insulin-like growth factors (IGFs) in the liver and other tissues. IGFs are responsible for mediating many of the growth-promoting effects of GH on target tissues, including bone, muscle, and other organs.
Uterine contraction is primarily regulated by other hormones, such as oxytocin, and is not directly related to the function of growth hormone. Lipolysis refers to the breakdown of stored fat into fatty acids and glycerol, and it is not a primary function of growth hormone. Melanocytes are the cells responsible for producing the pigment melanin, which determines the color of the skin, hair, and eyes.
Melanocyte production is regulated by other factors and is not directly influenced by growth hormones. While growth hormone does play a role in bone growth and development, specifically by stimulating the production of IGFs, it is not directly involved in the proliferation of bone cells. Therefore, the correct answer is option c.

21. A 300 N force acts on a 25 kg object. The acceleration of the object is
7500m/s
300 m/s
25m/s
12m/s
Answer:
\(\boxed {\boxed {\sf 12 \ m/s^2}}\)
Explanation:
Force is the product of mass and acceleration.
\(F=ma\)
The mass is 25 kilograms and the force is 300 Newtons, but we should convert the units to make the problem easier later.
1 Newton is equal to 1 kilogram meter per square second. The force of 300 N is equal to 300 kg*m/s²Substitute the known values in for the variables ( F and m).
\(300 \ kg*m/s^2= (25 \ kg) a\)
Since we are solving for a, we must isolate the variable. a is being multiplied by 25 kilograms and the inverse of multiplication is division. Divide both sides by 25 kg.
\(\frac{ 300 \ kg*m/s^2}{25 \ kg}= \frac{(25 \ kg) a}{25 \ kg}\)
\(\frac{ 300 \ kg*m/s^2}{25 \ kg}= a\)
The kilograms will cancel out (hence our earlier unit conversion).
\(12 \ m/s^2=a\)
The acceleration is 12 meters per square second.

Why does a virus lethal to us not infect animals? I know that RNA viruses mutate at 10,000 to a million times faster than DNA viruses. wouldn't that give enough time for the virus to mutate a ability to infect other organisms?
The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.
Why does a virus lethal to us not infect animals?For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.
With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

Please :( Based on your knowledge of evolution, are humans evolving? Support your answer with factual evidence as to
why or why not
Answer:
Jesus made every one evalution is false
When Charles Darwin introduced the theory of evolution through natural selection 158 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt. Today that battle has been won everywhere—except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as “intelligent design” to be taught as alternatives to evolution in science classrooms. When this article first went to press in 2002, the Ohio Board of Education was debating whether to mandate such a change. Prominent antievolutionists of the day, such as Philip E. Johnson, a law professor at the University of California, Berkeley, and author of Darwin on Trial, admitted that they intended for intelligent-design theory to serve as a “wedge” for reopening science classrooms to discussions of God.
The good news is that in 2005 the landmark legal case Kitzmiller v. Dover in Harrisburg, Pa., set binding precedent that the teaching of intelligent design in U.S. public schools is unconstitutional because the idea is fundamentally religious, not scientific. The bad news is that in response, creationists have reinvented their movement and pressed on. When they lost the ability to claim that creationist ideas are valid science, they switched to arguing that they were only supporting “academic freedom.” Worse, to further obscure the religious roots of their resistance, they now push for “critical analysis” of climate change, cloning research and other scientific endeavors that they paint as culturally oppressive.Explanation:

Consider the following story:
“During the summers when Xavier was a young boy (around 8 years old), his grandfather would take him to northern Ontario to go fishing on weekends. Shortly after his grandfather died his family left Ontario. He was never able to clearly remember the fishing trips. When he was 30 years old he moved back to Ontario with his wife. One weekend they decided to take a trip to northern Ontario to spend the weekend at a resort on one of Ontario’s many lakes. When they got out of the car, they were overwhelmed by the aromatic smell of the trees in the heavily wooded area by the lake. Suddenly, memories of the wonderful weekend fishing trips with his grandfather came flooding back to the him.”
Discuss the following questions:
Is this an example of a repressed memory? If not, why not?
If it’s not a repressed memory, then what is it? What accounts for the sudden re-emergence of this buried memory?
Could this account for other, more traumatic, kinds of “repression” as well?
Answer:
No.
Explanation:
This is not an example of a repressed memory because these are the good memories whereas the repressed memory are bad memories of childhood. It may be infantile amnesia due to the inability of adults to bring episodic memories memories of situations or events that occurs in their childhood. The sudden re-emergence of this buried memory is the experience of the same situation or place or event that occurs in the childhood. If a person visit to a same place which he gone in their childhood so the person remember the buried memory.
is lactase exergonic
Answer:
The correct answer is - yes lactase action is exergonic.
Explanation:
Lactase is an enzyme located in the small intestine of mammals including humans, however it is produced by many organisms in their body. Lactase is an essential enzyme as it helps in the digestion of the whole milk by breaking down the lactose, sugar present in milk.
Exergonic reactions are the reaction that releases energy by the breaking of molecules in any reaction. Generally, catabolic reactions are exergonic lie lactase catabolizes the lactose present in milk and release energy.
Thus, the correct answer is - yes lactase action is exergonic.

Explain homeostatic mechanism can conserve oxygen in diving animals
The mechanism to conserve oxygen in diving animal is diving reflex.
What is homeostatic mechanism?
Homeostasis is a system property that regulates variables so that internal circumstances stay steady and largely constant. Homeostasis can be seen in the regulation of body temperature and the balance of acidity and alkalinity.
Homeostatic regulation refers to the adjustment of physiological systems within the body and consists of three elements or mechanisms: (1) the receptor, (2) the control center, and (3) the effector.
What is diving reflex?
The diving reflex is a clever physiological mechanism that allows the body to manage and tolerate low oxygen levels. During the diving response, oxygen consumption is reduced via energy-efficient swimming or gliding behavior, as well as modulation of metabolism, heart rate, and peripheral vasoconstriction.

aberrant oligodendroglial-vascular interactions disrupt the blood-brain barrier, triggering cns inflammation
True, aberrant oligodendroglial-vascular interactions disrupt the blood-brain barrier, triggering cns inflammation.
Disruption of the blood-brain barrier (BBB) is vital to initiation and perpetuation of disease in multiple sclerosis (MS). We document an interplay among oligodendroglia and vasculature in MS that distinguishes human white count number damage from regular rodent demyelinating damage. we discover perivascular clustering of oligodendrocyte precursor cells (OPCs) in certain lively MS lesions, representing an inability to properly detach from vessels following perivascular migration.
Perivascular OPCs can themselves disrupt the BBB, interfering with astrocyte endfeet and endothelial tight junction integrity, resulting in altered vascular permeability and an related CNS infection. Aberrant Wnt tone in OPCs mediates their dysfunctional vascular detachment and additionally ends in OPC secretion of Wif1, which interferes with Wnt ligand function on endothelial tight junction integrity.
Aberrant oligodendroglial-vascular interaction in MS indicates that aberrant OPC perivascular migration no longer most effective impairs their lesion recruitment but also can act as a ailment perpetuator thru disruption of the BBB.

Answer:
The answer would be the flowers
Explanation:
The flowers have pollen in or on them that bees, wasps, and butterflies pick up while drinking nectar. The pollen is eggs and is spread from flower to flower.
Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.
What is flower?Pollination, the act of sexual reproduction in flowering plants, is how it happens. Stamens, the male sex organ, and pistils, the female sex organ, are found in flowers.
The portion of the stamen that carries pollen is called the anther. The male gametes are found in pollen. For reproduction to occur, pollen must be transferred to the stigma, a region of the pistil.
When a plant's own pollen nourishes its own ovules, self-pollination occurs. When animals or the wind carry pollen from one plant to another, cross-pollination occurs.
Cross-pollination has the benefit of preserving a species' genetic diversity. When environmental conditions change and organisms must adapt, genetic variety is useful. Some plant characteristics really work to stop self-pollination.
Therefore, Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.
