An epistatic allele in labrador retrievers ensures that ee lab pups are yellow. Two other alleles control coat color, where black is dominant to brown. What portion of yellow pups would you expect from a parental cross where one parent was yellow (Bbee) and the other was heterozygous
Answer:
1/4
Explanation:
Epistasis is defined as a phenomenon in a genetics where the effect of the gene mutation which dependent on the absence or the presence of the mutation in more than one genes.
In the context, an epistatic allele in the Labrador retrievers which ensures the ee lab pups that are yellow and the two other alleles which control coat color are black that is dominant to the brown.
Thus, 1/4 portion of the yellow pups would expect from the parental cross where one of the parent is yellow (Bbee) and the other is heterozygous.
Thus the answer is 1/4.

Which region in the brain we can find the Neural stem cells? --> Are they SGZ ( Subgranular Zone) and SVZ( Subventricle Zone)?
Answer:
Subgranular Zone.
Explanation:
Subgranular Zone is the region in the brain where neural stems are located. These neural stem cells are found in two zones of the dentate gyrus which is a part of the hippocampus in the brain, as well as in the striatum that is the part of the basal ganglia located deep within the cerebral hemispheres. So according to this information we can conclude that Subventricle Zone is the region where Neural stems cells are not located.

9. because of heat given off, only 10% of the energy is going to go to each level .
In a food chain and web, only 10% of the energy produced by a level in a food chain is passed on to its predator so there has to be many more “prey” than “predators”. If 2000 kcal of energy are available in grass, how much energy would be available to the cow that eats the grass? How about to the human that eats the cow?
Answer:
If only 10% of energy is passed down the cow would only get 200 kcal of energy from the grass. The human would get 10% less than that which is only 20 kcal of energy from the cow.

Asha went to visit her grandfather in the village .She found that he was worried about the productivity level of crops for that year. Asha suggested a naturalmethod and asked him to plant crops like pulses, gram and beans for a year and then follow with regular crops.A)What will you name the process suggested by her?B)What could be the reason for the decrease in crop productivity? C)What are the benefits of this process?
Answer:
Crop rotation.
Explanation:
Crop rotation is the method by which regular crops are cultivated after leguminous crops. Leguminous crop have nodules in their roots that has bacteria which fixes nitrogen for the plant which means that the plant produce their own fertilizer which can be used by the plant as well as a lot of nitrogen is also present for the other crop which increases productivity of the regular crops. The unavailability of nutrients is the main reason for the decrease of productivity. The main benefits of this method is increase productivity and nutrient level in the soil.

which would have most likely stopped Mendel from finding a pattern in his results
The options attached to the given question is attached here as well as in the comments of the question:
A.If having a wrinkled seed had been a recessive trait
B.If garden peas reproduced more quickly
C.If seed shape did not have a clearly dominant form
D.If having a smooth seed had been a dominant trait
Answer:
The correct answer is - C. If the seed shape did not have a clearly dominant form.
Explanation:
Mendel studied and perform his research on seven different traits in peas, which are – height, seed color, flower color, and seed shape. In Mendel’s study, every trait has traits that are clearly either dominant or recessive.
Similarly, the seed shape has a very clear dominant form which is smooth seed dominant over wrinkled seed that is a recessive trait. If this clear dominant form or recessive form could not be established, then Mendel’s experiment would have most likely stopped its progress.
The outcome of protein synthesis is ______.
A. A glucose molecule
B. An mRNA molecule
C. A protein
Answer:
C. A protein
Explanation:
The outcome of protein synthesis is a protein.
The process of protein synthesis is crucial to cellular function. Protein synthesis is the procedure used by cells to generate proteins. Thus, option C is correct.
What is the role of protein synthesis in the cell?Protein synthesis, sometimes referred to as protein biosynthesis, is an essential biological process that occurs inside of cells to replace lost proteins (due to export or degradation) with new proteins.
Proteins have a wide range of vital biological functions, including those as enzymes, hormones, and structural proteins.
Cells are made of proteins, and the word “synthesis” simply means “to make.” Thus, the process of producing proteins is known as protein synthesis.
Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.
Therefore, The outcome of protein synthesis is a protein.

Abiotic components: Sunlight, dead organic matter, river, stones, rocks, fertile soil, nutrients.Explanation:
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living beings and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
A few examples of abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.
Examples of biotic factors are plants, animals, insects, microorganisms, etc.
An example of an ecosystem in my locality is the native forest in the hills.
The forest is composed of many vegetable species, among which we may find trees, shrubs, herbs, grasses. We can also find lichens and fungi. Many mammal species such as little rodents, foxes, puma. Many bird species, among which we can find owls and some other birds of prey. There are different kinds of snakes and reptiles. There are amphibian species near the shore of the river that is crossing the forest. The soil is quite fertile, providing nutrients to the organisms. There is too much organic matter of vegetable origin, such as leaves or fallen and dead trees. Many microorganisms live in this dead matter. Insects are everywhere. There are some steep slopes in which stones, rocks, and tree roots hold the ground.

Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Belle, who was born on the same date at the same hospital. Mrs. Green, having recently seen Belle, is convinced that Belle and Georgia had been assigned to the wrong parents at the hospital. Mrs. Green thinks that Belle is her biological daughter. ABO blood analysis was performed on all individuals involved:Mr. Green: Type AMrs. Green: Type A Georgia: Type AMr. Blue: Type ABMrs. Blue: Type ABelle: Type O
Is Mrs. Green correct? Is Belle her biological daughter? Explain.
Answer:
Yes, Mrs Green is correct that Belle is her biological daughter
Explanation:
According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.
Based on the blood analysis, the following were obtained:
Mr. Green: Type A
Mrs. Green: Type A
Georgia: Type A
Mr. Blue: Type AB
Mrs. Blue: Type A
Belle: Type O
The genotype of the following blood types is as follows:
Type A - iAiA or iAi
Type B - iBiB or iBi
Type O - ii
Type AB - iAiB
From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.
However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.

write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond
(See the attached picture)
Direction: Write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond.
Answer:The goal of the sperms’ journey to the egg is to fertilize it. To do so, the sperm cell must pass through a long and challenging path. This is one of the reasons why the total number of motile sperm cells is very important, and a key parameter for a man’s potential to reach pregnancy with his partner.
The sperms’ journey to the egg begins with millions of sperm cells that are released into the female reproductive tract during intercourse. The sperm cells gain their full ability to swim when they are ejaculated into the reproductive tract.
Upon ejaculation, the sperm cells are enclosed in a fluid called seminal plasma or semen, which is a mix of fluids from the testes, seminal vesicles, prostate, and the bulbourethral glands. The fluid contains elements which protect the sperm cells during their journey towards the egg. The semen thickens and helps the sperm cells stay inside the woman – as close as possible to the cervix, which is the “gate” to the egg.
Liquid extends from the cervix, allowing the sperm cells from the semen to swim into the cervix. Only the strongest sperm cells will make it this far. Once through the cervix, the sperm cells swim across the uterus and into the fallopian tubes.
I hope it helps!!The sperm cell fertilizes the egg and forms a zygote, which is further divided into multiple cells and becomes a child. The division is the process of mitosis that takes place from the zygote to the child's development.
How is the zygote formed and developed?The sperm and the ovum are produced by the process of meiosis from the male and female, respectively, and when both fertilize, the zygote is formed. The fertilized zygote is a single cell, but later that cell is further divided mitotically and forms a morula, then a blastula, and then the gastrula.
The cells of the gastrula undergo cell differentiation, different organs are developed, and the baby is finally formed. The child then continues to grow in size, and different organs grow and form the mature organ system. After a certain age, the reproductive organs start to mature and are capable of forming the gametes.
Hence, all of these events occurred from the zygote to the child's maturity.

С
The change in amino acids shortens the polypeptide sequence.
D
The alternation of a single nucleotide encodes for a different amino acid.
Answer:
A . The entire sequence of amino acids is changed.
Explanation:
The entire sequence of amino acids is changed when the mutation occurs in the protein because amino acid is the building block from which protein is made. Mutation is the sudden change that is occur in the genetic makeup i.e. DNA when the cell is exposed to radioactive radiation of chemicals. So due to this change, the sequence of amino acids changed and they work differently.

Answer:
The answer is "The first choice".
Explanation:
The hypothesis of such a molecular clock says because DNA and protein sequences develop at a pace generally constant over time as well as between different organisms. The whole idea is thus incredibly beneficial and for estimation of the historical periods, if the molecular biological hypothesis is valid, then the most significant feature enabling DNA to act as a molecular clock it has a reliable mean mutation.
