Haploid and diploid are terms that represent the ______ of an organism.

Answers

Haploid and diploid are terms that represent the sets of the chromosome of an organism.

What do you mean by chromosomes?

The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).

When an organism's cells only have one set of chromosomes, the organism is said to be a haploid. All organisms that reproduce sexually are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.

The number of chromosomes found inside a cell's nucleus is known as the diploid chromosomal number. The symbol for this number is 2n. Each organism has a different one. In contrast to sex cells, somatic cells are diploid.

2. Anisogamy refers to a type of sexual reproduction in which two dissimilar gametes unite or fuse. The gametes may differ in size or form.

Example : human beings, the male gamete sperm is smaller and motile while the female gamete egg is non motile and larger.

3. having or involving a small motile male gamete and a large immotile female gamete.

plss help will mark brainlest.. ​

Answers

Transpiration is a water balance process mediated by stomata opening. Translocation is the transport process of photosynthetic substances from leaves to other tissues.

What is transpiration?

Transpiration is a water balance process.

Through stomata opening and closure (which depends on how hydrated the plant is) water vapor is expelled from the leaves.

If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.

By limiting water exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.

The equation to calculate transpiration is as follows,

E = Gv (Cvs - Cva)

Where,

E is transpiration.Gv is the total vapor water conductance.Cvs is the water concentration inside the leave.Cva is the air water concentration.

What is translocation?

Translocation is a fast and dynamic process through which photosynthetic products are transported from the leaves to other tissues of the plant to be used or stored.

This transport is done by the phloem cells through active transport or osmosis (depending on the substance).

The translocation of elements from the leaves to the roots is fast.

In conclusion,

The chemical equation for transpiration is E = Gv (Cvs - Cva). Translocation is the movement of photosynthetic products from leaves to other plant tissues.

(a) Explain why red blood cells burst when placed in some solutions of sodium chloride. ​

Answers

Answer: Red blood cells placed in a solution with higher water concentration compared to their contents will gain water by osmosis that will then swell up and then burst.

Explanation:

Osmosis causes red blood cells to release water when they are exposed to sodium chloride solutions that are more concentrated than their internal environment (hypertonic solutions).

Hemolysis is the term for this process. In an attempt to balance the solute concentration, water is pulled out of the cells by the high concentration of sodium chloride outside the cells, creating an osmotic gradient. The result is that the cells shrink and may eventually rupture or burst. Lack of water reduces internal pressure and destabilizes cell membranes, causing red blood cells to burst.

This phenomenon underscores how important it is to maintain the correct balance of solute concentrations to protect the structural and functional integrity of red blood cells.

How does sucrose move from source to sieve?

Answers

The sucrose move in source to sieve by active transport.

What is active transport?

Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.

In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element  by osmosis, which increases the hydrostatic pressure.
