Both blood and intestinal cells take in glucose by passive transport. Thus, the correct option is B.

A transport protein found in the plasma membrane facilitates diffusion, which is the passive movement of things like biological molecules or ions across a plasma membrane. Chemical energy is neither utilized nor required because compounds are moved from higher to lower concentrations.

Glucose is absorbed by the mechanisms of facilitated diffusion or passive transport across the membrane of red blood cells. The sugar glucose is transferred by active transport from the gut into intestinal epithelial cells.

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

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.

Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.

Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.

The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.

For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.

The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Therefore, it is well described above.

A=even more of the cell than when it was in water

Answer:

When a red onion cell is placed in a 5% NaCl solution, the central vacuole will occupy

B) less of the cell than when it was in water

This is due to plasmolysis

Explanation:

Plasmolysis is the process in which there is a loss of water from cells when these are placed in a hypertonic solution. The protoplast and vacuole shrinks away from the cell wall.

Hypertonic solution is that which has higher concentration of solutes (low water concentration) as compared to inside the cell. As water moves from high conc. to low conc., it moves from inside the cell to outside. Thus, the vacuole pulls away from the cell when placed in a hypertonic solution (5% NaCl).

The human respiratory system is composed by nose and mouth and continues through the airways and lungs. Air enters the respiratory system through the nose and mouth, passing through the throat (pharynx) and voice box or larynx.

The respiratory system allows the exchange of gases with atmospheric air, ensuring the concentration of oxygen in the blood, necessary for the body's metabolic reactions, and on the other hand serving as a route for the elimination of residual gases, such as carbon dioxide.

In this case, we can see the multicellular organisms show emergent properties; these are properties that exist due to many different components working together.
