Answer: This description is an example of camouflage adaptations.
Explanation:
The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

Eye color in a particular strain of fly is influenced by one gene with two alleles: a dominant allele that results in red eyes and a recessive allele that results in sepia eyes. A red-eyed female from a true-breeding population is mated with a sepia-eyed male. The Fl offspring are all red-eyed. The Fl flies are allowed to interbreed, producing the following in the F2 generation.
Females: 40 red eyes; 13 sepia eyes
Males: 39 red eyes; 11 sepia eyes
Which of the following best describes the likely mode of inheritance for the eye-color gene?
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.
Answers
Answer:
The correct option is a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
Explanation:
Available data:
Eye color is influenced by a diallelic gene R dominant allele results in red eyesr recessive allele results in sepia eyesCross: true-breeding red-eyed female with a sepia-eyed maleF1: 100% red-eyed.F2: Females: 40 red eyes; 13 sepia eyesMales: 39 red eyes; 11 sepia eyes
77% of the total progeny has red eyes and 23% has sepia eyes.
Among females, 75% is red-eyed, and 25% is sepia-eyed
Among males, 78% is red-eyed, and 22% is sepia-eyed.
The general phenotypic ratio is 3:1
If the eye-color gene was sex-linked, the phenotypic ratios would be different. There would be a higher proportion of red-eyed females than red-eyed males. Females would only express red eyes, while males would express red and sepia eyes. This is
Cross: X⁺X⁻ x X⁺Y (Note: The symbol + represents the allele R
Phenotype: red-eyed both and the symbol - the allele r)
Gametes) X⁺ X⁻ X⁺ Y
Punnett square) X⁺ X⁻
X⁺ X⁺X⁺ X⁺X⁻
Y X⁺Y X⁻Y
F2) 3/4 of the whole progeny would be red-eyed
1/4 of the whole progeny would be sepia-eyed
BUT
Females: 100% red-eyed
Males: 50% red-eyed and 50% sepia-eyed
These proportions are not coincident with the exposed real proportions
So,
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
If this gene was sex-linked, Males and females would not have similar phenotype ratios. This is FALSE.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.
If this gene was sex-linked, Males would display both phenotypes, but females would only be red-eyed. This is also FALSE.
According to this, we can assume that this is an autosomal gene. If this is true, then
Cross: Rr XX x Rr XY
Gametes) RX, RX, rX, rX
RX, RY, rX, rY
Punnett square:
RX RX rX rX
RX RRXX RRXX RrXX RrXX
rX RrXX RrXX rrXX rrXX
RY RRXY RRXY RrXY RrXY
rY RrXY RrXY rrXY rrXY
F2) From the whole progeny
12/16 = 3/4 = 75% would be red-eyed 4/16 = 1/4 = 25% would be sepia-eyedPhenotypic ratio 3:1
Among females
6/8 = 3/4 = 75% would be red-eyed, R-XX 2/8 = 1/4 = 25% would be sepia-eyed, rrXXPhenotypic ratio 3:1
Among males
6/8 = 3/4 = 75% would be red-eyed, R-XY 2/8 = 1/4 = 25% would be sepia-eyed, rrXYPhenotypic ratio 3:1
The phenotypic ratio in all cases are 3:1.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
Both males and females exhibit sepia eyes in equal proportions. This is FALSE
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
Males and females do have similar phenotype proportions of red eyes and sepia eyes. This is TRUE

Answers
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.
Therefore, The first stage and the stage the cell stays in most is Interphase.

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, 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 Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua 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?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answers
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children with type o. what blood type should he request on his dating survey? what must Opine’s blood type be in order to produce offspring with type O blood?
Answers
Answer:
He should request type O on his dating survey.
Opine's blood type must be AO to have a higher probability of producing O offsprings.
Explanation:
O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.
O blood type results are possible thanks to OO genotypes.
If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.
As regards the mother, her blood type should be OO.
We can see this more clearly in Punnet Square.
║ A ║O
O║AO║OO
O║AO║OO
There is a 50% of probability of having O offsprings with AO and OO.
║ A ║A
O║AO║AO
O║AO║AO
With AA and OO, the probability is 0%
║ A ║O
A║AA║AO
O║AO║OO
With both parents having AO, blood the probability of having a OO offspring is 25%.
In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.
