Answer:
23 chromosome pairs.
Explanation:
In humans, the DNA strands are packaged in a tightly coiled 1400 nm structure called the chromosomes. Since each cell contains the DNA therefore each cell contains the chromosomes.
The human genome is packaged into 46 linear chromosomes but since the humans are diploid organisms, therefore, the chromosomes form pairs with the homologous chromosomes and form 23 pairs of chromosomes. Every cell of humans possesses 23 pairs of chromosomes.
Thus, 23 pair of chromosomes is correct.
You conclude that the sucrose solution is hypotonic to the potato cells.
Explanation:
A solution is said to be hypotonic with respect to other solution if its concentration is less than the other solution to which it is compared.
A concentration of solvent molecule in a hypotonic solution is higher than hypertonic solution so solvent moves from hypotonic to hypertonic solution due to osmosis.
The increase in weight of potato shows that it has gained water i.e. the water has entered from the sucrose solution to cells. So, the sucrose solution is hypotonic to the cell sap.
Frogs-have adapted to water and grow webbed feet to swim faster it helps it survive to move away from prey
porcupine- have adapted to being attacked so they have quills that will shoot out when being threatened
Fish-overtime have adapted and grown gills to breathe under water

The entire process of manufacturing energy is known as oxidative phosphorylation, which takes place in the mitochondria, where ATP synthase enzyme is situated in the inner mitochondrial membrane and the F1-component protrudes into the mitochondrial matrix.
In the process, ADP combines with a phosphate to produce ATP. The energy liberated due to the hydrolysis of ATP into ADP is utilized to do cellular function, generally by coupling the exergonic reaction of the hydrolysis of ATP with the endergonic reactions.
The synthesis of ATP from ADP and Pi is an endergonic reaction with positive delta G.
