So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.
But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.

5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74 frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.873)
p² ≅ 0.02 q² ≅ 0.74 2pq ≅ 0.244)
q² = 0.13 p² = 0.4 2pq = 0.465) The dark-colored fur seems to have the greatest overall selective advantage
6) Dark lava changed the color of the substrate, from light to dark.
7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

Brian indicates that the mutation is in a gene found in the mitochondrial DNA. What does Brian mean by that and why did he signify mitochondrial DNA
Answer:
Change occur in the genetic makeup.
Explanation:
Brian means that the change occur in the genetic makeup of the mitochondrial DNA that change the structure as well as the function ability of mitochondria which is responsible for the generation of energy for the cell. The mitochondrial DNA are passed from mother to offspring through the egg cell. He signify mitochondrial DNA because the change occur only in the mitochondrial DNA not in the whole organism's DNA.
Brian indicates that the mutation is in a gene found in mitochondrial DNA. What Brian means by this is that mitochondria contain a single circular chromosome that encodes 13 proteins, and that may be due to abnormalities of mitochondrial DNA, to understand better we need.......
Abnormalities in mitochondrial DNAEach cell has several hundred mitochondria in its cytoplasm. Mitochondria contain a single circular chromosome that encodes 13 proteins, several ribonucleic acids (RNA, ribonucleic acid) and several regulatory enzymes. However, > 90% of mitochondrial proteins are encoded by nuclear genes. For practical purposes, it is assumed that all mitochondria are inherited from the cytoplasm of the egg, so mitochondrial DNA comes only from the mother.
Mitochondrial diseases can result from abnormalities of mitochondrial DNA or nuclear DNA (eg, deletions, duplications, mutations). Tissues with high energy production (eg, muscle, heart, and brain) are at particular risk of dysfunction due to mitochondrial abnormalities. Specific abnormalities in mitochondrial DNA result in characteristic manifestations. Mitochondrial diseases are equally common in men and women.
With this information, we can say that mitochondria have DNA and can undergo mutations, which can cause abnormalities in this DNA.

Two polypeptides, X and Y, have similar tertiary structures. X normally exists as a monomer while Y exists as a tetramer, Y4. What differences might be expected in the amino acid composition of X versus Y
Answer:
Due to number of amino acids.
Explanation:
The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of number of amino acids.
Amino acids are organic compounds that are formed of amino, carboxylic and a side group. They bond to form protein structures.
The amino acids fold in various structures like primary, secondary, tertiary etc. The basic contrast in an amino acid arrangement of polypeptide X and Y is that the X is made of small units while Y is made of larger units.
X polypeptide is a monomer that is it only has one unit of amino acid while Y is a tetramer that is it has four-unit of amino acids.
Therefore, the number of amino acids is the main distinction between X and Y tertiary structures.

In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F1 Generation 0 45 55 0 1
The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F2 Generation 23 31 22 24 0
Required:
a. Determine the genotypes of the original parents (P generation) and explain your reasoning.
b. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes.
Answer:
The genotypes of the original parents are
Male: X⁺Y Female: X⁻X⁻The Chi-square analysis leads us to accept the prediction of the parental genotypes.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
(a) The genotypes for the original parents (P generation) are
Male: X⁺Y
Female: X⁻X⁻
(b) The prediction of the parental genotype is accepted by the Chi-squared test analysis.
What is the eye color pattern in fruit flies?Drosophila Melanogaster is a fruit fly with abnormally big, brightly colored eyes.
The range in color from red to sepia to white reveals a lot about the genetic makeup of the fly.
(a) E = + ⇒ Dominant allele coding for wild-type eyes
e = - ⇒ Recessive allele coding for white eyes
Now, Crossing the : male wild-type with a female white-eyed
(Parental) = X⁺Y x X⁻X⁻
(Phenotype) = wild white
(Gametes) = X⁺ Y X⁻ X⁻
(Punnett square) = X⁺ Y
X⁻ = X⁺X⁻ X⁻Y
X⁻ = X⁺X⁻ X⁻Y
In (F1)generation = 2/4 = 1/2 = 50% of the progeny are expected to be wild-type females.
And 2/4 = 1/2 = 50% of the progeny are expected to be white-eyed males.
Thus, the percentages are almost 50:50, as the expected ones.
So, the genotypes of the original parents are
Male: X⁺Y
Female: X⁻X⁻
(b) Using Chi-squared test :
Observed fruit fly type:
Wild Type Male - 25
Wild Type Female - 31
White-eyed Male - 22
White-eyed Female - 24
Expected fruit fly type:
Wild Type Male - 25
Wild Type Female - 25
White-eyed Male - 25
White-eyed Female - 25
Now, chi square [tex]= \sum\dfrac{(O- E)^2 }{E}[/tex]
By putting numbers in the formula, we are getting
Wild Type Male - 0.16
Wild Type Female - 1.44
White-eyed Male - 0.36
White-eyed Female - 0.04
Now, X² = 0.16 + 1.44 + 0.36 + 0.04 = 2
Critical value = 7.82
X² (2) < critical value (7.82)
Thus, this is the evidence to accept the given hypothesis.

Which properties of water are most responsible for the capillary action in plants?
Answer:
The property of "cohesion forces" of the water makes them responsible for the capillary action in the plants.
Explanation:
Water molecules in the soil get pulled into the plant through roots and travel over the vessels and tubes in the stem to various parts of the plant. Leave surface have small pores, named as stomata or guard cells that will help in transpiration or evaporation. This process of transpiration will help the ground water to travel opposite to the gravity and travel all parts of the plant body carrying minerals and essential food particles.

A.
lagging strand
B.
ligase
C.
bases added to the 3’ end
D.
continuous replication
E.
DNA polymerase III
Answer:
The correct answer is - D. continuous replication.
Explanation:
Okazaki fragments are short DNA sequences synthesized in the lagging strand as DNA polymerase enzyme is able to synthesize only from 5' to 3' so nucleotide can not bind on 5' end but only 3' end and the DNA strands are antiparallel.
They are short fragments of DNA synthesized from RNA primers on the lagging strand and combined by the ligase enzyme. Okazaki fragments show a discontinuous manner in the synthesis of DNA.
The correct answer is D. continuous replication as they don't have it.
Okazaki fragments are brief DNA sequences synthesized withinside the lagging strand as DNA polymerase enzyme is capable of synthesizing simplest from 5' to 3^ high SO nucleotide can't bind on 5' cease however simplest 3' cease and the DNA strands are antiparallel.
They are brief fragments of DNA synthesized from RNA primers at the lagging strand and blended via way of means of the ligase enzyme. Okazaki fragments display a discontinuous way withinside the synthesis of DNA.
What are Okazaki fragments?Okazaki fragments are small sections of DNA that might be fashioned all through the discontinuous synthesis of the lagging strand all through DNA replication. They are essential due to the fact they permit each daughter strand to be synthesized, which is vital for molecular division.
Thus it is clear thsat Okazaki fragments are not associated with continuous replication.

Imagine you are a plant breeder. Friends sent you two different varieties of a snapdragon flower; each have golden leaves rather than green leaves. (Wild-type snapdragon plants have green leaves.) A cross between the two different varieties of golden snapdragons always produces progeny that have green leaves. This is an example of:
Answer:
Complementation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.
In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.
Hence, the above breeding is an example of complementation.
Keratinase is an enzyme produced by dermatophytes. Which organs in the body would these pathogenic fungi tend to proliferate in, and why
Answer:
The keratin-producing cells known as keratinocytes are the primary type of cells found in the epidermis. They originate from the stratum basale's stem cells. They act as a barrier from harmful environmental elements like pathogens and ultraviolet radiation. Dermatophytes are a group of physiologically and morphologically associated molds, which release an enzyme keratinase.
Keratinases are the serine proteases that destroy the keratin found in skin, nails, and hair.
The dermatophytes lead to infections of the hair, skin, and nails, as they obtain nutrients from the keratinized substances. These pathogenic fungi are most actively found in the external cornified layers of the cells of dead skin were they less likely to get determined and eliminated by the active dendritic cells.
