Meiosis I

At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis). Meiosis I proceeds through the following phases:

■ Prophase I: Prophase I is similar in some ways to prophase in mitosis.

Answer:

Six molecules of carbon dioxide produce twelve molecules of glyceraldehyde 3-phosphate. Out of twelve, ten molecules are required to synthesize ribulose bisphosphate by utilizing six molecules of ATP that can bind incoming carbon dioxide and restart the cycle. The hydrolysis of ATP produces six molecules each of ADP and inorganic phosphate.

Explanation:

Short term energy is the function of Lipids. So, the correct option is (D).

Lipids are defined as naturally occurring molecules which include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others. The main functions of lipids include energy storage, signaling, and serving as structural components of cell membranes.

Biological lipids are not large macromolecular polymers such as proteins, nucleic acids and polysaccharides that are formed by the chemical linkage of many smaller constituent molecules. Many of these molecular building blocks are similar or identical in structure.

These lipids are classified into a few major groups such as fatty acids, fatty acid derivatives, cholesterol and its derivatives, and lipoproteins.

Thus, Short term energy is the function of Lipids. So, the correct option is (D).

Answer:

energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

Answer:

B, Oxygen. :)

Explanation:

Answer:

2. Dominant 3. Recessive 4. H---zygous 5. Heterozygous 6. Hybrid 7. Purebred

Explanation:

2

Upper case letters always represent dominant alleles.

3

Lower case letters always represent recessive alleles.

4

"H---" means same, if you see too upper case letters or two lower case letters it's H---zygous.

5

"Hetero" means different, if you see one upper case and one lower case or two different letters, it's Heterozygous.

6

A hybrid is something with pieces of two different things, like hybrid cars that get energy from gas and heat.

7

I can't think of a way to memorize the word "purebred". Sorry.

Answer:

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Cyclins regulate the cell cycle only when they are tightly bound to Cdks. To be fully active, the Cdk/cyclin complex must also be phosphorylated in specific locations. Like all kinases, Cdks are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

i did quiz and got it right :)

The statements that best describe the first stage of cellular respiration are as follows:

Thus, the correct options for this question are A, D, and E.

Cellular respiration may be defined as a process through which the molecules of glucose are broken down into carbon dioxide and water with the liberation of energy in the presence of oxygen. This process takes place in the cytoplasm of the cell.

During the process of cellular respiration, a molecule of glucose is broken down into two molecules of pyruvate (pyruvic acid). This demonstrates the first stage of cellular respiration which is known as glycolysis.

Therefore, the correct options for this question are A, D, and E.

Answer:

K.E = 50 J  

Explanation:

Given data:

Mass of object = 4 Kg

Speed of object = 5 m/s

K.E = ?

Solution:

Formula:

K.E = 1/2mv²

by putting values,

K.E = 1/2 × 4 Kg × ( 5m/s)²

K.E = 1/2 × 4 Kg ×25 m²/s²

K.E = 50 J   (Kgm²/s² = J)

Answer:

D.) Wet soil absorbs heat more slowly, due to water's high heat capacity.

Explanation:

Just took the quiz

The mixtures of the minerals, organisms, nutrients and compounds are called soil. Due to water's high heat capacity heat is absorbed slowly by the wet soil.

The type of soil that is filled with water molecules in its pores and lacks air in it are wet soil, on the other hand, the soil that has no moisture content in it is called dry soil.

When there is a variation in the temperature then the ability of the soil or substance to absorb heat is called heat capacity.

Water present in the pores of the wet soil has more heat capacity and therefore the heat absorbed by the wet soil is slower than the dry soil.

Therefore, option D. wet soil is slower in absorbing heat.

According to chemical evolution, synthesis of organic molecules would need to occur first for life to evolve. Option C is correct.

The theory of modern chemical evolution is based on postulate that, on primitive earth, the most complex molecular system, which lead to formation of first functioning cell, arise from mixture of simpler chemicals.

Chemical evolution of organic chemicals was preceded by the and physical chemical conditions of the primitive Earth. A two step process is proposed by scientists to explain life origin :

Therefore, concept of biogenesis must be placed for evolution of in chemical evolution. Thus, option C is correct.

                  "function of snakes"

Snakes are elongated,legless,carnivorous reptile of the suborder serpents.Like all other squamates,snakes are exothermic,amniotic vertebrates covered in over applying scales.Many species of snakes have skulls with several more joints than their lizard ancestors,enabling them to swallow prey much larger  than their heads with their highly mobile jaws.To accommodate their narrow bodies,snakes,oared organ appear one in front of other instead of side by side,and most have only one functional lungs.Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.Legless lizard have eyelid and external ear.

A scale protect the body of the snakes,aids it in locomotion,allows moisture to be retained within,alters the surface characteristics such as roughness to aid in camouflage,and in prey capture (such as Acrochordus).

Snake scale originates from the epidermis.The integument of the snakes in covered with two primary scale type,both originating from the epidermis.Small scale over the dorsum and lateral surface of the snake.Whereas larger scales cover the vent rum.
