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

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

How does sucrose move from source to sieve?
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.

Answer:trait encoding for short plant structure to reduce transport of water
Explanation:The Sahara Desert is a zone which receives very low or no precipitation. This region receives maximum of sunlight not received by any other biome. The soil is typically sand which is highly porous and lacks essential growth nutrients necessary for plant growth. The plants grown around Sahara Desert are xerophytic plants. These plants undergoes several adaptations in order to prevent loss of water through transpiration. Trait encoding for short plant structure to reduce transport of water is a xerophytic adaptation.

1.write the chemical equation for transpiration
2.what is translocation ??,give the chemical equation for translocation
plss help will mark brainlest..
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.You can learn more about translocation and transpiration at
