What ratio of plants in the offspring would you predict from a Yy x Yy cross?
Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.
Difference between phagocytes and red blood cells
Why is taxonomy important to scientists?
HELP ! can someone please explain to me on how to set it up ?
Answer:
The correct answer is -
4/4
100%
Explanation:
In this question, it is given that allele B (blue) is dominant over allele b (purple) and both Randal and cell have the same genotype of recessive alleles that is bb and bb.
The offspring of these two will be the same as the due to gametes Randall and cella produce are same which is b and b.
b b
b bb bb
b bb bb
here all four out of four have the same purple skin with 100% chances.
A triangle has side lengths 9, 10, and 12. Is it acute, obtuse, or right? Explain.
A. Right; 92 + 102 = 181 and 122 = 144, so a? + b2 = c2.
O
B. Obtuse; 92 + 102 = 181 and 122 = 144, so a+ b2 < c.
C. Acute; 92 + 102 = 181 and 122 = 144, so a2 + b2 >c2.
I dont really understand what yours asking but that triangle is acute because its sides are less then 90 degrees. Does that help??
Describe the role that the protein INSULIN plays in a red blood cell
Answer:
helps maintain blood sugar
:)
Explanation:
The beta cells of the pancreas produce a peptide hormone called insulin. It is an anabolic hormone that regulates the activity of proteins, fats and carbohydrates in the body.
In blood cells insulin helps to:
Keep blood glucose levels
The role can be explained as:
Insulin is the anabolic protein that helps in breaking down carbohydrates, fats and proteins consumed in food. They signal the muscle and liver cells to absorb the glucose molecules present in the blood.They help the cells and tissues to regulate the glucose uptake for energy and also to store the excess glucose as a glycogen molecule.When there is an increased glucose concentration in blood cells then insulin cues liver cells to convert it into glycogen for future use.In the case of insufficient blood glucose it alerts liver cells to split the glycogen molecule into glucose for furnishing power and to counteract out the equilibrium in the body.Therefore, insulin regulates blood glucose levels.

New alleles can arise in both asexual and sexual reproduction.
Which of the following statements is TRUE based on the disadvantages of sexual and asexual reproduction.
A- Gametogenesis is the only source of genetic variation for sexual reproduction
B- This answer choice is wrong
C- Mutations are the only source of genetic variation for asexual reproduction
D- Meiosis is the only source of genetic variation for sexual reproduction
Answer:
C - Mutations are the only source of genetic variation for asexual reproduction
Mutations are the only source of genetic variation for asexual reproduction.
What is mutation?
A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings. There are numerous explanations for why mutations typically don't have significant effects.
Therefore, Mutations are the only source of genetic variation for asexual reproduction.

A. Presence of Cell membrane
B. Presence of Nucleus
C. Presence of Cell Wall
D. Single-Cell vs Multicellular organisms
Answer:
Single cell vs Multicellular organisms

Researchers used DNA sequencing techniques to find similarities of Hox genes in roundworms, arthropods, mollusks, echinoderms, cephalochordates, and vertebrates. What did they find out about these genes? Select all that apply. A. Hox genes provide information about evolutionary relationships. B. Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times. C. Hox genes are regulatory genes that determine body plans of animals. D. Only some animals that have been tested have Hox genes, suggesting that Hox genes have no function and only evolved recently.
Answer:
(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.
Explanation:
Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.

1. What gene involved in skin pigment varies a great deal across populations?
2. Why doesn’t skin cancer explain this selection?
3. What does strong sunlight do to folate?
ALOT OF POINTS!!!!!
Answer:
Explanation:12werffdew
Answer:
1.A number of genes have been positively associated with the skin pigmentation difference between European and non-European populations. Mutations in SLC24A5 and SLC45A2 are believed to account for the bulk of this variation and show very strong signs of selection.
2.Cancer can circumvent negative selective pressures due to its ability to accumulate mutations that cause genetic diversity in tumor cells as the cells proliferate. Cancer seems to have evolved a propensity for, or at the very least, a selection for fitness.
3.Folate levels decrease depending on sun exposure, study says. 05 Feb 2019 --- Folate levels decrease during the months when solar radiation is higher and ultraviolet radiation proportionately affects folate levels in the blood.
