Diffusion is an important process in animals and plants.

Biology
1 answer:
Paraphin [41]3 years ago
8 0

Answer:

Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.

Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.

Example for animals: Animals using glucose and oxygen in diffusion.

Examples for plants: Plants using carbon dioxide to photosynthesize.

How is carbon moving between the air and found it decreasing
ratelena [41]

Answer:

Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Answer:

<u>the bottleneck effect</u>

<u />

Explanation:

Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.

Some mutations or alleles may become extinct from the population.

<u />

Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other  phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.
