Answer:

d

Explanation:

The statement that does not apply to the traits present in a population as a result of artificial selection is:

d. Traits are present only in the phenotype and not in the genotype of the population.

In artificial selection, traits are deliberately selected and bred by humans based on their desirability. These selected traits can be present in both the phenotype (observable characteristics) and the genotype (genetic makeup) of the population. Therefore, option d is incorrect as traits can be present in both the phenotype and the genotype.

Infections have no method for plotting all alone and lean on their host cells to imitate and spread. They can spread through direct contact, droplets in the air, or vector-borne transmission by organisms like mosquitoes, among other methods. The correct answer is (D).

A virus enters a host's body by traveling along cell surfaces until its proteins begin to bind to cell receptors. After that, the virus and the cells fuse, allowing the virus's DNA or RNA to enter the cells and begin reproducing.

A virus must enter a host through a portal of entry, replicate or disseminate within the host, and be transmitted to a new host through a portal of exit before it can be transmitted.

Coughing, sneezing, laughing, and close personal contact spread airborne diseases. Contact Infections are communicated when an individual with the illness has direct in essence contact with a not individual have the sickness, and the microorganism is passed from one to the next.

Explanation: . . .

A fistula is a connection between two tubes that should not connect. For example, an opening between the anus and nearby skin is called Anorectal fistula.

A tiny passageway known as an anorectal fistula forms close to the anus opening (bottom hole) between the skin and bowel's end. A pus-filled area (abscess) develops in the tissue nearby as a result of an infection close to the anus. It's possible for a little passage to remain when the pus drains.

In most cases, an accident or surgery leads to fistulas. Fistulas can also develop due to infection or inflammation. An infection-related immune response is what leads to Crohn's disease, which is an intestinal inflammation. Fistulas are infection-filled passageways that can develop when the lining of the intestine becomes ulcerated.

3. drought

4. babies born

6. carrying capacity

7. population density

8. logistic growth

9. exponential curve

Explanation:

The first statement is true. Plants require light energy to power photosynthesis, the process by which they convert light energy into chemical energy stored in the form of carbohydrates.

The second statement is false. While plant cells do use cellular respiration to generate ATP (adenosine triphosphate), a molecule that serves as a source of energy for cellular processes, this process does not involve transforming light energy into chemical energy. Rather, cellular respiration involves the breakdown of carbohydrates, such as glucose, to release energy.

The third statement is also false. While plants do require carbon dioxide and water as raw materials for photosynthesis, they do not create energy from these substances directly. Rather, they use the energy from sunlight to power the chemical reactions that transform carbon dioxide and water into carbohydrates.

The fourth statement is true. Cellular respiration involves the breakdown of carbohydrates, such as glucose, to release energy in the form of ATP. This process occurs in the mitochondria of plant cells and is essential for providing energy for cellular processes such as growth, reproduction, and maintenance.

Option D is correct. Synapse is the structure which does communication between two neurons or between a neuron and a target tissue occur

A synapse is an unique junction where electrical and chemical signals are exchanged between two neurons or between a neuron and a target tissue. The electrical signal of the sending neuron is changed into a chemical signal at the synapse, where it is transmitted across the space between neurons. The electrical signal is transferred to the following neuron when the chemical signal connects to receptors on the receiving neuron.

The cell body is the substantial middle portion of a neuron and houses the nucleus as well as the majority of the organelles.

Nucleus: The nucleus houses the genetic material and serves as the control centre of the neuron.

Dendrites - A neuron's branching processes that receive messages from neighbouring neurons are known as dendrites.

The fundamental components of the nervous system are neurons. They are specialised cells that communicate with various nerve, muscle, and gland cells. A cell body, dendrites, and an axon make up a neuron. The nucleus and other organelles are found in the cell body. Short extensions of the cell body, called dendrites, receive signals from other neurons. A lengthy projection that sends signals to other neurons or muscles is called an axon. Neurotransmitters are substances that are released by neurons to communicate with one another.

Answer:

by using resources faster than they can be

replaced

Explanation:

As population of the world continues to grow, there is greater demands for resources which are obtained from the environment such as crude oil for energy, solid minerals for various applications, wood for furniture etc.

Demand for these materials increase exponentially as population increases thus they are extracted at a faster rate than nature can replace them. This will eventually harm the environment on which humans depend as population increases.

The Mendel's law that states that two hereditary factors separate when gametes are formed is known as the law of segregation.

What is Mendel's Law of Segregation?The law of segregation is a fundamental principle of genetics discovered by Gregor Mendel, an Augustinian monk who lived in Brno, Moravia, in the mid-19th century. Mendel deduced the law of segregation by performing a series of experiments with pea plants, during which he tracked the inheritance of visible traits from one generation to the next.

In Mendelian genetics, this principle is referred to as Mendel's First Law, or the Law of Segregation. It asserts that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization, resulting in the re-establishment of the paired state in the zygote.

The statement that describes the relationship between the reactants of photosynthesis and the products of cellular respiration is as follows: The products of cellular respiration serve as the reactants of photosynthesis (option B).

Photosynthesis is the process whereby green plants synthesize their own food (sugar) in the presence of sunlight.

During photosynthesis, plants take in carbon dioxide and water from the air and soil respectively. Glucose sugar is produced in the chloroplast of the cell.

Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.

Based on the above explanation, it can be said that photosynthesis combines water and carbondioxide as reactants to form glucose and oxygen as products.

On the other hand, cellular respiration combines glucose and oxygen as reactants to form carbondioxide and water as products.

Therefore, cellular respiration and photosynthesis are opposite of one another.

Sex chromosomes are those chromosomes in which sex-determining genes reside. Humans have two sex chromosomes, one inherited from the mother and the other from the father. These two chromosomes differ between males and females.

Females have two X chromosomes, while males have one X and one Y chromosome. Match each phenotype description to its corresponding sex chromosome genotype in humans The five phenotypes listed in the question are described below and matched to their respective sex chromosome genotypes.

XX with SRY on X: This is a genetic disorder that causes individuals with a male gender identity to have two X chromosomes and a single X chromosome with the SRY gene. This can cause the development of female genitalia, although a male gender identity is present. XY with SRY deleted: The Y chromosome determines male development. If the SRY gene, which is located on the Y chromosome, is absent or deleted, male development may not occur as expected, and individuals with an XY genotype may develop female characteristics.

XXX: Females have two X chromosomes, so individuals with three X chromosomes are genetically female. However, the presence of additional sex chromosomes can result in abnormal development.

XXY: An extra X chromosome in males, also known as Klinefelter syndrome, can cause infertility, smaller testicles, reduced body hair, and breast enlargement. XYY: Males with two Y chromosomes, or Jacob's syndrome, are taller than average but may experience delayed language development, learning difficulties, and attention deficit hyperactivity disorder (ADHD).

Therefore, the matching of each phenotype description to its corresponding sex chromosome genotype in humans is shown below:

Phenotypically female with some abnormalities and overexpression of X chromosome genes: XXX Phenotypically male with an increase in average stature: XYY Phenotypically male but karyotype indicates the presence of only X chromosomes: XY with SRY deleted Phenotypically male with sterility and hypogonadism: XXY Phenotypically female but karyotype indicates the presence of both sex chromosomes: XX with SRY on X.
