Explanation:
In plants tall T is dominant to short t .perform the following cross Tt x Tt what is the probability of producing a short plant
25% or 1/4 chance
Explanation:
When crossing these two heterozygous parents, you will get the phenotype 3:1. This means...
75% chance of plant being tall
25% chance of plant being short
Since T is dominant and we are using simple Mendelian inheritance, the heterozygous offspring (Tt) will be tall as well.
This means there is a 25% or 1/4 chance of the plant being short.

g a true breeding pea plant with round and green seeds was crossed to a true-breeding pea plant with wrinkled and yellow seeds. Round and yellow seeds are the dominant traits. The F1 plants were allowed to self-fertilize. What is the probability that an F2 plant will be green and round?
Answer:
The probability of producing a round and green plant from this cross is 3/16
Explanation:
This question involves two distinct genes coding for seed shape and seed colour. In the seed shape gene, allele for round seeds (R) is dominant over allele for wrinked seeds (r), while in the seed colour gene, allele for yellow seed (Y) is dominant over allele for green seeds (y).
A truebreeding plant means that the plant possesses homozygous genotype. Hence, a truebreeding pea plant with round and green seeds will have genotype: RRyy while true-breeding pea plant with wrinkled and yellow seeds will have genotype: rrYY. These two parents will produce F1 offsprings with genotype: RrYy (heterozygous).
When the F1 offsprings are self-crossed (RrYy × RrYy), the following allelic combinations of gametes will be produced by each F1 parent: RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible F2 offsprings with a phenotypic ratio 9:3:3:1 will be produced
9- Round yellow offsprings (R_Y_)
3- Round green offsprings (R_yy)
3- Wrinkled yellow offsprings (rrY_)
1- Wrinkled green offsprings (rryy)

is it a good idea to sterilized thins that are to be sent to the moon
Answer:
Yes, it is a good idea to send the objects on the moon after sanitization or after sterlization so that it not causes harm in any way.
There is a bit different type of environment on the moon and the objects must not be sent as it is on the way.
The objects has to be sterlized so that it does not reacts entering into the moon's environment.
The objects sent on the moon are usually metals and other reactive or non reactive materials that can affect the people carrying the objects, spaceship or via any other means.
So, its better to send sterlized things into the space so that it cannot harm anyone.
Seen more clearly in small populations, _______ is when allele frequencies change due to random chance, not selection.
Answer:
Genetic drift
Explanation:
Genetic drift are changes that occur in the frequency of alleles in a population that are mainly due to chance. For genetic drift to occur, this change must occur randomly, and examples is usually seen mostly in small populations.

What best describes the Frank-Starling law?
a. The Frank-Starling law states that the slower the heart rate, the greater the cardiac output.
b. The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood.
c. The Frank-Starling law states that the greater the stroke volume, the greater the heart rate.
d. The Frank-Starling law states that the more the ventricular muscle cells are stretched, the more forcefully they contract.
Answer:The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood
Basically, the FSL states that the greater the stroke volume of the left ventricle will increase, as the volume of the the ventricles increases due to ventricular contraction, leading to systolic contraction.
If the volume of the blood in the Ventricle is increased, the blood volume stretches the ventricular walls and the ventricle contracts.The amount of blood ejected from the ventricle increased(stoke volume).Therefore, the higher the contraction of the ventricles, Myocyte stretch, the more the volume of blood in the ventricle pushed, and the more the amount of the blood ejected from the ventricle as Stroke Volume.

Why are nonnative species a threat to biodiversity? Check all that apply.
They provide more niches for animals to live in.
They do not have natural predators to regulate their population growth
They cause the climate in an area to become cooler.
They provide food resources to native organisms.
They compete with native organisms for resources.
Previous Activity
The correct answers are B. They do not have natural predators to regulate their population growth and E. They compete with native organisms for resources.
Explanation:
Nonnative species include any species that does not belong to an ecosystem but was introduced to it. Nonnative species are considered are an important threat to biodiversity and native species because they usually disrupt the natural equilibrium in the ecosystem.
This usually occurs because nonnative species population grow rapidly due to the lack of natural predators; for example, Asian carps which are native from Asia and were taken to the U.S. are eaten by other fish and animals in their native ecosystem, but once they are introduced in another ecosystem their population increases due to lack of predators. Additionally, nonnative species often compete with native species for resources, this also happens with the Asian carp that competes for food such as snails or mussels with native species in the U.S.

How are meiosis and mitosis different?
O A. Mitosis has anaphases I and II, but meiosis has only anaphase I.
O B. Meiosis produces four cells, but mitosis produces two cells.
O C. Chromatids are formed only during the process of meiosis.
O D. Mitosis produces haploid cells and meiosis produces diploid cells.
Answer:
B
Explanation:
Meiosis and mitosis are different, as meiosis produces four cells, but mitosis produces two cells that are present in Option B, as mitosis produces two genetically identical daughter cells, while meiosis produces four genetically diverse daughter cells.
What are meiosis and mitosis?Mitosis is a process of cell division that occurs in somatic (non-reproductive) cells, where a single cell divides into two identical daughter cells. The purpose of mitosis is for the growth, repair, and replacement of cells in the body, whereas meiosis is a type of cell division that occurs in reproductive cells (germ cells) and is involved in the production of gametes (sperm and egg cells) in animals. Meiosis involves two rounds of cell division, known as meiosis I and meiosis II, and makes the gametes.
Hence, meiosis and mitosis are different, as meiosis produces four cells, but mitosis produces two cells that are present in option B.

Lysosomes are organelles formed by numerous digestive enzymes. These enzymes allow lysosomes to be able to digest substances and even cellular apparatus, when needed.
The digestive function of lysosomes can be observed in the removal of the interdigital membrane of the developing mammalian fetus, by the action of digestive enzymes that have the ability to remove this entire membrane and any other undesirable tissue for the next stages of development of the fetus.
_________14. In photorespiration, carbondioxide is produced in the _________ when glycine is converted to serine.
A. Peroxisome B. Lysosome C. Mitochondria D. Chloroplast
Answer:
Option D, chloroplast
Explanation:
The process of photorespiration starts in the chloroplast when oxygen attaches to the RuBP. This produces three compounds namely – a) Three carbon compound (3-PGA) and b) Two carbon compound (phosphoglycolate). 3-PGA act as an intermediate to the Calvin cycle and before entering this cycle two of its carbon are removed. To recover lost carbon, plants taken in carbon through series of reactions involving phosphoglycolate. One fourth of the total carbon transported through this pathway is released as CO2. Since this entire process takes place in chloroplast, it can be said that CO2 is produced in chloroplast
Hence, option D is correct

Q: Explain Carbohydrate metabolism in fed state, importance and problems in human body. Support your answer by biochemical pathways.
Answer:
Explanation:
After having a carbohydrate rich meal concentration of some hormones, especially insulin change in your body. Insulin promotes the uptake of glucose by cells(particularly muscle cells, adipocytes, liver cells). It also increases the rate of glycolysis and glycogenesis and decreases the rate of gluconeogenesis and glycogenolysis.
These important metabolic pathways cause burning up glucose to make ATP that all cells in our body need and also storing it in the form of glycogen in the liver which is a very important food storage. Metabolism of carbohydrates also causes fat to be deposited in adipocytes which is basically why we have stuff like keto diets(no or very little carbohydrates and mainly fats consumed) for losing weight!

During a marathon, runners draw heavily on their internal reserves of glycogen (carbohydrate) and triglycerides (fat) to fuel muscle contraction. Initially, energy is derived mostly from carbohydrates, with increasing amounts of fat being used as the race progresses. If runners use up their muscle glycogen reserves before they finish the race, they hit what is known as "the wall.," a point of diminished performance that arises because fatty acids from triglyceride breakdown cannot be delivered to the muscles quickly enough to sustain maximum effort. One trick that marathon runners use to avoid the wall is to drink a cup of strong black coffee an hour or so before the race begins. Coffee contains caffeine, which is an inhibitor of cyclic AMP phosphodiesterase. How do you suppose inhibition of this enzyme helps them avoid the wall
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
Categorize each relationship as mutualism or parasitism
The question is unclear, is there more to it?
I cannot answer this question without knowing the circumstances, but it is good to remember that mutualism is where both species and/or participants benefit, and parasitism is where one species benefits and the other one is harmed.
Think of mutualism like the word mutual, so when people say " the feeling is mutual" it means that both parties feel and/or express the same feelings. Parasitism should be thought of like a parasite. When one is infected or has contracted a parasite, the parasite will live off of its host body making it ill or even causing death as it drains resources from its host to benefit itself.
