Answer:

the 3rd one would be most relative

Explanation:

The forest community each with 100 individuals distributed among four different tree species (W, X, Y, and Z)  would have the most relative abundant option as correct 25W, 25X, 25Y, 25Z.

Diversity is described because of the unique types/sort of lifestyles paperwork gift at the earth. Diversity plays an amazing position with the aid of using Maintain the stability of nature, law of weather, cleansing of air and water, carbon sequestration and international weather change, organic productivity, vitamins cycling, stabilize earth from erosion, and lots greater function.

Species are frequently described as the biggest organization of organisms wherein any people of the ideal or mating kinds can produce fertile offspring, normally through reproduction. Other approaches to defining species encompass their karyotype, DNA sequence, morphology, behavior, or ecological niche.

Thus it is clear that forest communities would have the most relative abundance are 25W, 25X, 25Y, 25Z.

Explanation:

Answer:

It is expected that accessions/lines that exhibit the same bands in SDS-PAGE are phylogenetically similar (or even identical, duplicated, accessions) and therefore they can be removed when developing a core collection of germplasm. Subsequently, the accessions of the core collection can be clustered into subgroups (subpopulations) based on the distances observed between lines, reflected by different protein band patterns observed in SDS-PAGE. It is expected that these subpopulations adequately contain the genetic diversity of the core collection (useful in breeding programs).

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is a technique widely used in molecular biology to separate proteins based on their molecular weights. In crop improvement programs, this information can result useful to identify accession lines and develop core collections. A core collection is a limited set of lines or accessions/varieties obtained from a large germplasm collection that is expected to contain the genetic diversity of crop species. In this case, cowpea lines that exhibit the same bands in SDS - PAGE are expected to be phylogenetically similar (or even identical/duplicated accessions), thereby these lines can be removed in order to conserve one accession in the core collection. Subsequently, the remaining lines can be classified by a phenogram based on distance measures clustered by UPGMA (unweighted pair group method with arithmetic mean). This cluster analysis enables the construction of a phylogenetic tree from a distance matrix based on protein patterns in SDS-PAGE, thereby obtaining subpopulations (clusters) which will be useful in breeding programs.

Mining in a area of wilderness can provide great succes as long as you know the area well and know some things about where to mine and not.

Answer: Yes, it is better to mine in a wilderness area than a developed area.

Explanation: Mining is carried out to gather raw materials that serve as the foundation for any country's or region's growth. It is more likely to occur in a wilderness area than in a developed area because mining usually has a negative impact on the environment.

The ores recovered by mining, such as oil, coal, metals, and others, cannot be obtained from any developed location, and the mining process destroys settlements in developed areas.

Answer: The statements that correctly describe the structure of pyruvate dehydrogenase (PDH) complex are:

--> E2 contains three domains.

--> A regulatory kinase and phosphatase are part of the mammalian PDH complex.

--> Several copies each of E1 and E3 surround E2 .

Explanation:

Enzymes are proteins that speeds up a metabolic reaction by lowering the amount of energy needed to start the reaction. The type of enzyme in a cell will determine the metabolic processes that will occur in it.

Pyruvate dehydrogenase complex which is located at the mitochondria matrix, is a group of enzyme that catalyzes the breakdown of pyruvate, which is the end product of glycolysis, to form acetyl-CoA. The product formed from the reaction which is acetyl-CoA in turn enters the citric acid cycle where it is further oxidized for cellular respiration.

The structure of Pyruvate dehydrogenase complex consists of:

--> Three catalytic enzymes: These include;

• E1: This is the first enzyme of the PDH complex called pyruvate dehydrogenase. It catalyzes the removal of one carbon atom from pyruvate which leads to the production of hydrohyethyl.

• E2: This is the second enzyme of PDH complex called dihydrolipoamide S-acetyltransferase. It catalyzes the transfer of hydroxyethyl group to oxidized form of covalently bound lipoamide, and the resulting acetyl group is then transferred to free coenzyme A to form ACETYL-CoA and reduced dihydrolipoamide. Several copies each of E1 and E3 surround E2 and it consist of three DOMAINS. These domains include: N-terminal 9 kDa lipoyl domain, 4 kDa peripheral subunit-binding domain and C-terminal 28 kDa catalytic (acetyltransferase) domain.

• E3: This is the third and last enzyme of PDH complex called the flavoprotein dihydrolipoamide dehydrogenase. It re-oxidizes the lipoyl group of dihydrolipoamide-E2 to form lipoamide-E2 and NADH.

--> Two regulatory enzymes: The activities of E1 which is the rate limiting step of PDH complex regulated by phosphatases (activators) and kinases (inhibitors).

--> A binding protein: these aids in the binding of E2 to E3 enzyme in the core of PDH complex.

Answer: N-terminal green fluorescent protein (GFP)

Explanation:

Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid.

Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.

GFP is Green Fluorescent Protein, and it is a protein produced by the jellyfish Aequorea victoria that emits bioluminescence in the green region of the visible spectrum. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.

There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.

Answer:

The diagram below represents some stages in the life cycle of humans. The numbers in the diagram represent various processes in the cycle.

1. "The processes reduce the amount of genetic information from each parent by half."

During sexual reproduction, a specialized cell division process called meiosis occurs. Meiosis involves two consecutive divisions, resulting in the production of four haploid cells (gametes) from a diploid cell.

2. "Each parent only contributes half of the genetic information that is contained in his or her own cells."

As mentioned earlier, meiosis results in the formation of haploid gametes. Each gamete contains only one set of chromosomes, which is half the number found in the parent's diploid cells.

During meiosis, homologous chromosomes pair up, and genetic recombination occurs between them, shuffling and exchanging genetic information.

3. "Each egg (or each sperm) will carry only half of the genetic information contained in the parent's body cells."

This statement reiterates that gametes (eggs or sperm) are haploid cells containing only one set of chromosomes. When a cell undergoes meiosis to produce gametes, it divides twice, resulting in four cells with half the genetic information of the parent's body cells.

3.) How do you know when the first day of the menstrual cycle is? What happens?

A.) first day of menstrual bleeding is considered Day 1 of the cycle.

4.) What is the function of FSH?

A.) FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.

-TheUnknownScientist

Answer: 3. Day 1 of your cycle is the first day of your period, meaning the first day of full flow (spotting doesn't count). During this time, the uterus sheds its lining from the previous cycle. Between days 1 – 5 of your cycle, new follicles (sacs of fluid containing eggs) begin to develop within your ovaries. 4. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries. FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary.

Explanation:

Answer:

Glucose present as monomers within the cell will exert more osmotic pressure than a single glycogen molecule, resulting in endosmosis and the lysing of cells.

Also, the presence of free glucose molecules will result in increase in weight of the liver due to lack of efficient packing as in glycogen as well as the association ofnthe glucose molecules with water molecules.

Explanation:

Glycogen is a polysaccharide composed of glucose monomer units linked to Each other by α-1,4-glycosidic binds. α-1,6-branches arises at about every 10th glucose residue in the straight chain. Thus animals more glucose molecules to be stored within a much smaller space, thereby incresing the bulkiness of glycogen. Glycogen molecules are insoluble in the aqueous medium of the cell because it doesn't have enough free polar groups to participate in hydrogen bonding with water and are stored as granules and therefore do not affect the water potential or osmotic balance of the cell.

On the other hand, glucose molecules are highly soluble in water because it has many free polar -OH grours that form hydrogen bonds with water. If the glucosyl residues in large numbers of glycogen molecules were replaced with an equivalent number of molecules of free glucose, the free glucose will exert a high osmotic pressure inside the cell, causing the entry of water in the cell by endosmosis resulting in swelling and lysis ofnthe cell. Also, the space occupied by these free glucose units within the cell will be much larger than that of glycogen whichmenables efficient packing ofthe glucose molecules.

Meiosis is a type of cell division that is specific to germ cells (gamete cells).

Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. Each daughter cells are genetically unique to the parental cell and are haploid in nature.

Gamete cells are typically divided by this mechanism of cell division. This is because when toe distinctive gamete cells from male and female are fused together, the resultant zygote will have the entire set of genetic material.

The gamete cells significantly have half the amount of genetic content. Due to this, it is also known as reductional division.
