Answer:
A positive feedback causes to continue of negative feedback cause it to stop or start
Explanation:
A positive feedback occurs to help increase the output or increase the changes. While a negative feedback occurs to decrease or reduce the output or decrease the change. A positive feedback amplifies the results of any reaction to make the reaction more quickly and the negative feedback results in a reaction to reduce the system to its original state or stable state. Thus a positive feedback occurs to continue while negative feedback causes it to stop or to start.

What is genomics?
The set of DNA of an organism is called its genome. There are 3 billion base pairs of DNA and virtually, every single cell in the body will have a complete copy of the letters, or codes that compose the human genome.
DNA has all the required information to build the entire human body. A unit of DNA carrying the instructions for the formation of a specific protein or a set of proteins is referred to as a gene. Every one of the 20,000 to 25,000 estimated genes in the human genome codes for an average of three proteins. Genomics is the study of genomes.

Stem cell lookup presents remarkable promise for understanding basic mechanisms of human improvement and differentiation, as properly as the hope for new redress for illnesses such as diabetes, spinal cord injury, Parkinson’s disease, and myocardial infarction. However, human stem cell (hSC) research additionally raises sharp moral and political controversies. The derivation of pluripotent stem cell strains from oocytes and embryos is fraught with disputes about the onset of human personhood. The reprogramming of somatic cells to produce brought on pluripotent stem cells avoids the moral issues particular to embryonic stem cell research. In any hSC research, however, dilemmas arise involving sensitive downstream research, consent to donate materials for hSC research, early medical trials of hSC therapies, and oversight of hSC research. These moral and policy issues want to be discussed along with scientific challenges to make certain that stem mobile lookup is carried out in an ethically fabulous manner. This article affords a crucial evaluation of these issues and how they are addressed in contemporary policies.

Anaerobic and aerobic cellular respiration are both biological processes that result in the production ATP molecules. Which of the following best compares anaerobic and aerobic cellular respiration?
a Aerobic respiration occurs in the cytoplasm and anaerobic takes place in the mitochondria.
b Aerobic respiration only occurs in muscle cells and anaerobic occurs in blood cells.
c Aerobic respiration produces alcohol and anaerobic respiration produces lactic acid.
d Aerobic respiration uses oxygen and anaerobic respiration does not.
Answer:
the answer would be D.
Explanation:
Anaerobic respiration and aerobic respiration produce ATP. Aerobic respiration uses oxygen. In anaerobic respiration oxygen is not used. Option d is the correct answer.
What is cellular respiration?Cellular respiration is a process in which a cell uses oxygen and carries out different cellular processes. In this process, energy is produced. There are two types of cellular respiration, such as aerobic respiration and anaerobic respiration.
In anaerobic respiration, oxygen is not used. An example is glycolysis. Glycolysis takes place in the cell cytoplasm. 2 ATP is released by this process.
In aerobic respiration, oxygen is used. Example: In the presence of oxygen, the pyruvate enters the Krebs cycle and the electron transport chain. This process takes place in the mitochondria.
In this aerobic process, the maximum amount of ATP is released. In aerobic respiration, the complete oxidation of glucose takes place , but in anaerobic respiration, complete oxidation does not take place.
Hence, option d is the correct answer. Aerobic respiration uses oxygen. Anaerobic respiration does not use it.

trichodysplasia spinulosa polyomavirus small t antigen synergistically modulates s6 protein translation and dna damage response pathways to shape host cell environment is
Unknown
Trichodysplasia spinulosa is a disfiguring skin disease caused by the trichodysplasia spinulosa–associated polyomavirus (TSPyV).¹ Like other polyomaviruses, TSPyV expresses the large T and small T (sT) antigens, but how these proteins regulate trichodysplasia spinulosa pathogenesis is unknown.
What is trichodysplasia spinulosa polyomavirus?
Trichodysplasia spinulosa is a rare cutaneous condition that has been described almost exclusively in immunocompromised patients, typically organ transplant recipients, on immunosuppressive medication regimens.
It is also known by many other names, including viral-associated trichodysplasia, viral-associated trichodysplasia, pilomatrix dysplasia, and ciclosporin-induced folliculodystrophy, although the latter name is incorrect. A total of 32 cases has been documented in the medical literature as of the beginning of 2016. Despite its rarity, TS is thought to be underdiagnosed, and the rising number of patients using immunosuppressive medication regimens raises the possibility that its occurrence may increase.According to some sources, TS is a developing infectious disease.

Trees that grow in a forest tend to grow very tall, with few branches. The same species of tree grown in an open area tends to grow shorter and wider, with many branches. The stimulus responsible for these different growth patterns is the amount of
wind striking the tree
⊝
light reaching the tree
⊝
nutrients in the soil
⊝
water in the ground
⊝
Which one is it?
Answer:
The correct answer is A) light reaching the tree
Explanation:
In a forest, there are lots of trees and they are all competing for sunlight so they are forced to focus all their energy on growing taller so they don't get stuck in the shadow of another tree, however, the trees that grow in a large, open area have little to no competition for sunlight, so they can relax and spread out their branches because there's lots of room.
Light, water, and nutrients play a crucial role in the adaptation and evolution of species. The trees of the same species will be taller in the forests, whereas in the open grasslands the height of the trees will be short.
The correct answer is:
Option B. Light reaching the trees
The light plays a crucial role in the height of trees as:
1. Light is essential for the survival of trees. In a forest, a large number of organisms are present, which fight for shelter, food, and light. Thus, to achieve more light, trees are taller.
2. In open grasslands, the trees are shorter and wider, because they do not have neighboring trees that fight for light and water.
Thus, the correct answer is Option B.

As concentration of substrate is increased in a reaction catalyzed by an enzyme, the reaction rate will stop increasing once saturation is reached because.
As concentration of substrate is increased in a reaction catalyzed by an enzyme, the reaction rate will stop increasing once saturation is reached because all enzymes are actively engaged in a reaction.
In the field of science, enzymes can be described as biological catalysts that speed up a reaction.
An enzyme is specific for its activity as a specific substrate fits into the active site of the enzyme. When the concentration of a substrate is increased, the rate of reaction will also increase until saturation is achieved. This will be the point where there will be no more free active sites of enzymes left for substrates. Each enzyme will already be having a substrate at this point.
In order to further increase the reaction rate, the quantity of the enzyme should also be increased so that there are more active sites present for substrates.
Although a part of your question is missing, you might be referring to this question:
As concentration of substrate is increased in a reaction catalyzed by an enzyme, the reaction rate will stop increasing once saturation is reached because
A. There are too many enzymes available and not enough substrate
B. once the enzyme reacts once, they cannot react again

the answer to this question is option 2. it is so because sun rises in east and sets in west. and since noon is 2:00, at 4:30pm the sun will be at west
Answer:
Option 2
Explanation:
The sun rises in the east and sets in the west so, at 4:30 pm, it would have been starting to set down a little. Thus, the position of the sun would be at the west side and the shadow would be on the east side. Options 1 and 2 would be wrong. A shadow would only be short when it is at noon where the sun is directly above the person so Option 4 is also wrong. The correct answer should be Option 2.

Are gender traits completely a result of societal expectations? Justify your answer.
Answer:
No. Gender traits in humans are largely determined by biophysical processes.
Explanation:
There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.
f a rabbit breeder crossed a white rabbit and a black rabbit in a complete dominance pattern, then all of the offspring would be either white or black in color. If the rabbits showed a pattern of incomplete dominance, breeding a white rabbit and a black rabbit together would produce all gray rabbits. Lastly, if the rabbits showed a pattern of codominance, then breeding a white rabbit and a black rabbit would produce rabbits with black and white spots. Using your knowledge of inheritance, explain how the genotypes produce different phenotypes in each inheritance pattern.
Answer:
- Complete dominance: one allele masks the expression of the other gene variant or the phenotype is caused by the absence of gene function when both alleles are recessive.
- Incomplete dominance (codominance): both alleles are expressed and contribute to the phenotype
Explanation:
Complete dominance is a type of dominance by which one allele (dominant allele) completely masks the effects of another allele (recessive allele) in heterozygous individuals (i.e., individuals carrying two different gene variants or alleles). On the other hand, codominance refers to a type of incomplete dominance where both alleles in the genotype are observed in the phenotype. Complete dominance is caused when the recessive allele is not expressed, while if both alleles are expressed it is called incomplete dominance.
