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.

Answer:

The immune system is a host defence system that combines multiple mechanisms to protect an organism from several pathogens and the development of disease. The endocrine and immune system crosstalk and multiple immune processes are involved in endocrine diseases. Defects of immune tolerance associated with genetic and environmental factors result to the development of autoimmune diseases such as autoimmune thyroiditis and diabetes mellitus type 1. In addition, a mixture of immune cells and mediators is considered to be implicated in thyroid cancer development and progression. Multiple cytokines and the evolving inflammatory process are involved in the pathogenesis of insulin resistance and diabetes mellitus type 2 whereas immune mechanisms related to lymphocytes and cytokine circuits may play a role in the pathogenesis of osteoporosis. Several studies have recently been published regarding the therapeutic implications of immune system mechanisms on endocrine diseases. For complete coverage of all related areas

Answer:

Why is vision considered to be a more effective sense in the terrestrial environment than in the aquatic environment?

Mostly its species bias. Our eyes are adapted to be more effective in a terrestrial environment during daylight. But sea creatures have far more impressive eye adaptations to seeing in the water where our eyes are less effective. The most amazing eyes across all species are the eyes of the octopus. In the water eyes don’t need to see color. Wasting valuable space on the retina for color receptors make it hard to see in the low light found in underwater environments. But the octopus’s eyes see color without having any color receptors. They do this by having lenses that act as a prism and separates light into its various colors. The octopus’s brain aligns the image scattered by color by where each color hits the retina. This allows it to see great in low light and also “see” colors. It uses this for camo to change its colors to blend in with its surroundings both to hunt prey and ide from predators. It can change colors instantaneously. The interesting thing about the octopus is it has no central brain. Its entire nervous system can act as individual brains allowing extreme ability to multitask. One of its eight limbs is thinking about what it will do while another is thinking both independently and with communication to the collective nervous system. reaction time of the octopus’s nervous system is unbelievable. We are very slow by comparison probably because a central brain is far less efficient when it comes to processing and reacting to stimuli. Anyway the question is about eyes so I will end my tangent there. The octopus eye system is probably the most advanced eye that exists. They even climb out of the water and demonstrate great visual acuity while out of the water. Our eyes are extremely limited when we are underwater.

Answer:

A

Explanation:

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.

Explanation:

Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.

Answer: on organism is harmed while to the other benefits

Explanation:

Predation and parasitism are similar because, in both predation and parasitism, one organism is harmed while the other benefits. Therefore, option B is correct.

The act of eating all or a portion of the body of another organism, the prey, is known as predation. Herbivory is the term for predatory behavior in which the prey is a plant.

When one creature, the parasite, feeds on another, the host, hurting or even killing the host, the connection is said to be parasitism. The parasite stays within or on the host's body. Tapeworms, fleas, and barnacles are a few examples of parasites.

Thus, predation and parasitism are similar because, in both predation and parasitism, one organism is harmed while the other benefits. Therefore, option B is correct.

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.
