Explanation:
A directional flow of electric charge
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart. Actually, electrons would go in the reverse direction across the cables.
What is electric current ?A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
The cell phone, trains, ships, refrigerator, and the motors in appliances like food processors all run on electricity. To be useful, electric energy must be converted into other forms of energy like heat, light, or mechanical.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart.

4.) What is the function of FSH?
Answer:
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.

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.

Which method would be best suited for neutralizing the acidic components of waste?
a. Incineration Incineration
b. Discharge to sewers, streams, and rivers Discharge to sewers, streams, and rivers
c. Chemical treatment Chemical treatment
d. Biological treatment
Answer: The method best suited for neutralising the acidic components of waste is chemical treatment. Option C.
Explanation:
Chemical wastes are seen during industrial processes. These wastes include: acids, alkalis, organic solvents, detergents, oils, dyes and heavy metals ( example; mercury, copper and lead). Normally, these wastes should be treated and made harmless before they are emptied into the rivers, lakes and seas. If not treated, the effect of these chemicals on the aquatic ecosystems is extremely harmful.
CHEMICAL TREATMENT of waste is a procedure which is carried out on dangerous acidic waste products to change its chemical properties by neutralisation with basic solutions. Neutralisation is a chemical reaction between a base and an acid. The products formed are salt and water which are less harmful to the ecosystem.
The ACIDIC components of the chemical wastes should be neutralised with an appropriate base solution before disposal to avoid it's harmful effects on the aquatic ecosystems. This is because most chemical wastes are non- biodegradable.

Explanation:
Case 2: In Ghana, cowpea is a legume plant that is a significant source of nutrition for people in this country. Attempts are being made to improve the yield and hardiness of this plant through a national crop improvement program. What has complicated this effort is the existence of several different collections of cowpea seeds. (Oppong-Konadu E, Akromah I, and Adu-Dapaah O. 2005. African Crop Science Journal 13:117-123) 1. How would you use protein analysis via SDS-polyacrylamide gel electrophoresis to sort through these collections so that duplicates could be eliminated and the remaining specimens could be sorted into subgroups that could then be further studied for properties of value in crop improvement
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.
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.
