Answer 1

Complete question:

Suppose a graduate student is studying a loss-of-function mutation in the mouse gene zigzag. Whereas wild type mice have straight tails, zigzag mutant mice have tails with two sharp kinks, so that the tail looks like the letter Z. To determine how the zigzag phenotype is inherited, he performs the crosses listed in the first column of the table below, using parents from true-breeding lines. Three possible sets of results from these crosses are shown. Determine the mode of inheritance of the zigzag gene that would yield each result set.

Mode of inheritance Options:

cytoplasmic-linked recessive inheritance,  maternal effect inheritance, genomic imprinting (paternal allele is inactive), genomic imprinting (maternal allele is inactive), x-linked recessive inheritance

Note: You will find the table in the attached file

Answer:

Set A: X-linked recessive inheritanceSet B: maternal effect inheritanceSet C: genomic imprint (paternal allele is inactive)

Explanation:

SET A:

X-linked recessive inheritance: This pattern refers to a recessive mutated allele that expresses the abnormal character and is linked to the X chromosome.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype---> 50% zigzag (all males)   ;  50% wild type (all females)    

      Genotype---> ½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) X+ Xz     x   Xz Y    

F1) Phenotype---> From the whole progeny: 25% wild type females ; 25% wild type males ; 25% zigzag females ; 25% zigzag males - 50% wild type animals + 50% zigzag animals

     Genotype---> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype---> 100% wild type animals (50% females + 50% males)

      Genotype --->  ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype---> From the whole progeny: 50% wild type females ;  25% wild type males ; 25% zigzag males

      Genotype --->  ¼ X+ X+ ; ¼  X+ Xz   ;  ¼ X+ Y  ;  ¼  Xz  Y

SET B:

Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. The progeny genotype is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. This effect is commonly seen in insects, but it might also occur in mammals and plants. A much known experiment about this effect is the one performed on Limnea sp snail.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype-->100% zigzag animals, due to the female´s phenotype, Xz Xz      

      Genotype--> ½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) Xx Xz     x   Xz Y    

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, Xx Xz      

     Genotype--> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+X+      

      Genotype --> ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+ Xz      

      Genotype---> 100% wild type animals      

SET C:

Genomic imprint (Paternal allele inactive): Refers to a pattern that characterizes for epigenetically inheritance and for unequally functional paternal and maternal genomes. Males X chromosomes are inactive or imprinted and have a different function from those females X chromosomes. This is a common pattern in some mammals, insects and angiosperms. The paternal allele can not be expressed which causes an unequal contribution to the progeny phenotype.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype--->100% zigzag animals, because the male´s X chromosome is imprinted or inactive      

      Genotype--->½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) Xx Xz     x   Xz Y    

F1) Phenotype--->50% wild type animals ; 50% zigzag animals.  Due to both the female´s chromosomes, Xx Xz      

     Genotype---> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype--->100% wild type animals, due to the female´s phenotype, X+X+      

      Genotype ---> ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype--->50% wild type animals ; 50% zigzag animals

      Genotype ---> ¼ X+ X+ ;  X+ Y  (Wild type)  

                            ¼  X+ Xz   ;  ¼ Xz Y  ( zigzag)

False. There are estimated to be millions of species on Earth, and taxonomists are still discovering and describing new species all the time. In fact, it is believed that only a fraction of the total number of species on Earth has been described so far.

Taxonomists use various methods to identify and classify new species, such as DNA analysis, morphological characteristics, and geographical distribution. Additionally, some species may be difficult to describe and may require specialized knowledge and equipment. Therefore, while taxonomists have described a large number of extant species, there are still many more waiting to be discovered and documented.


All extant species have not been described by taxonomists. Taxonomists are scientists who classify and describe organisms based on their characteristics and relationships. While taxonomists have made significant progress in cataloging known species, there are still many organisms that have not been discovered or properly classified. The vast biodiversity of our planet makes it difficult to document every species, and new species are continually being discovered. Furthermore, some habitats, such as deep-sea environments or remote regions, are challenging to explore, which contributes to the incomplete documentation of all extant species.

In humans, brown eyes are dominant to blue eyes. If a blue-eyed man has children with a brown-eyed woman whose mother has blue eyes, what percentage of the brown-eyed offspring do you expect will be heterozygous

Answers

Answer:

50%

Explanation:

This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.

According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).

Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.

Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.

Survivorship curves are graphs that show the proportion of individuals in a population that survive to each age. Based on the survivorship curves, the statement that is best supported is option A: American robins have a high survival rate for most of their lifespan and then decline rapidly in old age.

Survivorship curves are categorized into three types: Type I, Type II, and Type III. Type I curves show a high survival rate for most of an organism's lifespan, with a rapid decline in old age. Type II curves show a relatively constant death rate throughout an organism's lifespan, while Type III curves show a high death rate for young individuals, with a sharp decrease in death rate for those that survive to adulthood.

The survivorship curve for American robins shows a Type I pattern, indicating that they have a high survival rate for most of their lifespan, with a rapid decline in old age. In contrast, the survivorship curve for common green darners shows a Type III pattern, indicating that they have a high death rate for young individuals, with a sharp decrease in death rate for those that survive to adulthood.

Looking at the table, we've got records sets A, B, C, D, and E, every with corresponding values for mass, speed, and intensity of indentation. We are inquisitive about the connection between speed and kinetic electricity.

Kinetic strength is given by way of the system:

Kinetic electricity = 0.5 * mass * velocity²

Analyzing the information sets, we are able to see that the mass remains steady throughout all information sets, except for record set E. This permits us to the consciousness of the variant in pace and its impact on kinetic power.

Upon comparing the data sets, we look at that in the information set E, despite the better mass, the velocity stays regular at 12 m/s. However, the kinetic power is the best on this statistics set because of the more mass.

To analyze the direct courting between pace and kinetic power, we should take into account the facts units wherein best the velocity varies at the same time as maintaining the mass steady. Therefore, the first-class proof to provide an explanation for the connection between pace and kinetic strength is discovered in records units A, B, and C.

In conclusion, the combination of facts units that serve as the first-rate proof to provide an explanation for the connection between speed and kinetic strength is ABYC.

A clay layer in the soil that resists the flow of groundwater is called d) an aquitard. An aquitard is a layer of low permeability that slows down or restricts the movement of water between aquifers.

It can be made up of materials such as clay, silt, or shale, which have a low hydraulic conductivity and therefore limit the amount of water that can pass through them. In contrast, an aquifer is a layer of permeable rock or sediment that can transmit water at a useful rate. An artesian aquifer is a confined aquifer where the water is under pressure, causing it to rise up to the surface without pumping.

The piezometric surface, also known as the water table, is the level below which the soil and rock are saturated with water. It represents the boundary between the unsaturated and saturated zones in the soil, and it fluctuates depending on the amount of rainfall and groundwater recharge in the area.

Answers

What is a biped?

One of the earliest adaptations made by hominids was bipedalism, and there are several theories as to how the human ancestors acquired it. One of them claims that after a group of our ancestors started living in Savannah habitats, bipedalism emerged (open areas covered with grasses). The Savannah lineages didn't have many trees to climb, so the upright posture let them see predators in the distance. Other lineages remained in the forests, where they could use the treetops and branches for protection and to collect food.

The second theory links the use of tools to the evolution of human bipedalism. The two forelimbs are free to explore the environment, aid in the use of tools, and even gather food while moving because a species does not move on all four limbs.

With this knowledge, we can conclude that bipedalism gave the human race a free arm to build technology and allowed them to move more slowly while walking, among other benefits.

Housing rats in a complex social environment with much stimulation leads to some changes in brain structure, including b) all of the given answers.

Housing rats in a complex social environment with much stimulation can result in various changes in brain structure. These changes include increased cortical mass, increased dendritic branching of cortical neurons, and prolonged neural health, well into senescence. The complex social environment provides opportunities for social interactions, cognitive stimulation, and physical activity, which can lead to enhanced brain development and plasticity. Increased cortical mass suggests structural adaptations in the brain, potentially indicating improved cognitive abilities. The increased dendritic branching of cortical neurons signifies increased synaptic connections and neural complexity, which can enhance information processing and learning. Prolonged neural health into senescence suggests that the enriched environment may have a protective effect against age-related cognitive decline.

a. endoparasite
b. parasitoid
c. ectoparasite
d. metaparasite

Answers

When a mosquito bites you and consumes some of your blood, it is acting as an ectoparasite. So, option C is accurate.

An ectoparasite is an organism that lives on the external surface of its host and derives its nourishment or resources from the host's body. These parasites can be found on various animals, including humans, and they typically feed on blood, skin cells, or other bodily fluids.

In the case of a mosquito, it feeds on the blood of its host by piercing the skin with its mouthparts and sucking blood. The mosquito does not live inside the host's body but rather feeds externally. Therefore, the correct answer is option c, ectoparasite.
