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.

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:

The correct answer is -  would be double which is 1472 mm Hg.

Explanation:

According to Boyle's law that says the relationship between volume and pressure of a gas at constant pressure shows an inverse relationship which means if volume will increase then pressure will be decrease and vice versa.

P1V1 = P2V2 .........Boyle's law

Given: P1 = 736 mm Hg

          V1 = 50 mL

P2 = ?

V2 = 25 mL

Solution:

from the Boyle's law

(P1V1)/V2 = P2

736×50/25 = P2

P2 = 1472

So the decreasing the volume to half increases the pressure double. It proves it follows Boyle's law

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.

Therefore, meiosis is a type of cell division that is specific to germ cells (gamete cells).

Answer:

energy used by decomposers

Explanation:

Energy used by decomposers are the ecosystem obtain energy and nutrients from plants.

An ecosystem, also known as an ecological system, is made up of all the organisms and the physical setting in which they live. The nutrition cycles and energy flows connect these biotic and abiotic elements.

Photosynthesis is how energy enters the system and is absorbed by plant tissue. Animals play a significant part in the transfer of materials and energy through the system by eating plants and one another.

In addition to facilitating nutrient cycling by transforming nutrients held in dead biomass back into a form that can be easily utilised by plants and microorganisms, decomposers also release carbon into the atmosphere through the breakdown of dead organic matter.

Therefore, Energy used by decomposers are the ecosystem obtain energy and nutrients from plants.
