correct answer is B; if the allele is expressed after reproduction has occurred.
The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.
When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.
An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

What is the function of cholesterol in the cell membrane?
A. To allow substances too pass through
B. To prevent the hydrophobic tails from sticking together
C. To make more room inside the cell membrane
D. To help the cell recognize self and non self
The function of cholesterol in the cell membrane is C. To make more room inside the cell membrane.
What is the importance of the cholesterol?Cholesterol affects the bilayer structure of biological membranes in a variety of ways. It alters lipid bilayer fluidity, thickness, compressibility, water penetration, and intrinsic curvature.
Cholesterol molecules control the fluidity of the cell membrane, which allows the cell to maintain its shape. If cholesterol is missing from the cell membrane, excess fluidity may lead to cell lysis, or the breakdown of the cell.
As a result, cholesterol is required for cell membrane stability.
In conclusion, the correct option is C.

How are seeds produced?
Answer:
When the ovum is fertilized by pollen tube core, it starts a process of differentiation which leads to the seed generation. In angiosperms, the fruit formation occurs from the ovary of flowers, simultaneously and in a similar way to the formation of seeds.

what is the equation for photosynthesis? why is it important for the plants to have both cellular respiration and photosynthesis(think about the equations)
Answer:
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.

Answer:
This question is incomplete.
But from what is provided, the answer is biotechnology
Explanation:
The use genes of microorganisms to produce human insulin involves the use of biotechnology via the process of recombinant DNA technology. Recombinant DNA technology involves the joining together/ligation of two or more DNA molecules (in this case the DNA of the microorganism and the DNA sequence coding for insulin in humans) of different species in a microorganism. The microorganisms used here are called transcription vector. This is because the microorganisms are only used to duplicate/produce the insulin and the insulin are not expressed in the microorganisms. E. coli and Saccharomyces cerevisiae are two most common microorganisms used in the production of insulin.

1. In a soil ecosystem, matter _________________ and energy ___________________.
Answer:
Recycled, not recycled
Explanation:
In a soil ecosystem, matter is recycled and energy isn't recycled.
Matter is recycled through biogeochemical cycles. Matter has to be recycled because it can neither be created, nor destroyed, and as such, recycling is the only option left.
Energy isn't recycled because most of the energy gotten is used by organisms, as gotten from the plants already, and thus, when it gets to the food chain there isn't much left to be recycled.

What is the problem which fermentation is able to FIX?
Cell has a limited supply of NAD
Cell has a limited supply of oxygen
Cell has too few mitochondria
Cell has too many glucose
Answer:
Cell has a limited supply of NAD+Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.

Flagella proteins are found in the extracellular matrix of lung tissue. How do the cells of the lung detect these proteins? a. complement system b. toll-like receptors c. eosinophils d. NOD e. helper T-cells
Answer:
The correct answer is b.
Explanation:
TLRs are transmembrane type proteins 1, they are abundantly expressed in fibroblasts and epithelial cells, as well as in cells of the immune system, including macrophages, dendritic cells, B and T lymphocytes, and their expression is regulated by pathogens, cytokines, microenvironmental factors, and possibly endogenous ligands. Due to their location and the type of ligands that bind them, these receptors have been divided into two large groups: the TLRs of cytoplasmic membranes (TLRs 1, 2, 4, 5, 6 and 10) and the TLRs of endosomal membranes (TLRs 3 , 7, 8 and 9). TLR5 located in the basolateral membrane of epithelial cells recognizes flagellin, a structural protein that makes up flagella.
In this assignment, you will think of scientific questions that will help you better understand the role of DNA and chromosomes in the expression of heritable traits in an organism. You will then conduct research to answer these questions. Finally, you will compose a typewritten document that states your questions and provides your answers.
Answer:
1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.

What do you mean by amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.
Moreover, amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Therefore, these 12 amino acids are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine and arginine.
