would it be better to mine in a wilderness area than a developed area?
Answer:
Yes.
Explanation:
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.

Rainforests are habitats for many plants and animals. However, habitat fragmentation is occurring because of human activity. When a rainforest is fragmented, a large area is divided into small patches that are isolated from each other. Species living in these patches are more likely to become extinct as a result of overcrowding and competition.
Which of the following is the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem?
A.
constructing boundaries and fences around each habitat patch
B.
building natural green pathways across the original habitat to join all the patches together
C.
building concrete roads across the original habitat to join all of the patches together
D.
introducing new species that compete with the existing species in each habitat patch
Building natural green pathways across the original habitat to join all the patches together. Option B
What is rain forest?A rainforest is characterized by towering, largely evergreen trees and heavy rainfall. Some rainforests have existed in their current form for at least 70 million years, making them the oldest existing ecosystems on Earth.
Hence we can see that the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem is building natural green pathways across the original habitat to join all the patches together.

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex. E2 contains three domains. The complex contains multiple copies of each of three enzymes. A regulatory kinase and phosphatase are part of the mammalian PDH complex. The core of the complex is made up of several copies of E1 . Several copies each of E1 and E3 surround E2 .
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.

When the gene encoding a certain cytoskeleton protein is deleted, the resulting mutant cells round up and do not form their normal appendages. These mutants can be rescued when a gene encoding an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, but not when a gene encoding a C-terminal GFP fusion is expressed. Which fusion protein is appropriate to use in studying cellular localization and activity
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.

The diagram below represents some stages in the life cycle of humans. The numbers in the diagram represent various processes in the cycle.
Identify the process(es) represented by 1 and 2. State how these processes (1 and 2) affect the amount of genetic information provided by a parent to its offspring.
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.

What is Meiosis?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.

Answer:
Indeed, rabbits, in most of the planet, tend to have their fur colored brown, copper or other similar shades. Now, in the Arctic regions, these animals do not have this color, but a white one, similar to the environment that surrounds them. This is so because these animals, for evolutionary reasons, have adapted their fur to the snowy environment that surrounds them in the Arctic, in order to avoid being detected by potential predators, protecting themselves and trying to ensure their survival.

Storage polysaccharides, like starch and glycogen, often contain over a million glucose units. The energetic cost of synthesizing polysaccharides is high (about one high-energy phosphate bond per sugar residue added). Suppose that in a liver cell, the glucosyl residues in large numbers of glycogen molecules were replaced with an equivalent number of molecules of free glucose. What problems would this cause for the liver cell
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.
