3. How does oxygen cross into the cell?

Answers

Answer 1

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

Answer 2

The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion has been one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

What is osmosis?

Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of the osmosis movement of the water takes place.

There are mainly three types of the osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis has been passive transport as water moves from low solute concentration to high solute concentration.

Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.

Therefore, The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion has been one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

Why is it important for gametes to be haploid cells?

Answers

It is important that the chromosomes are haploid, because when the sperm and the egg fuse together the cell will have 46 chromosomes.

The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.

Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.

Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.

Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.

Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.

Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.

According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?

by increasing carbon dioxide and decreasing oxygen

by increasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and decreasing oxygen

The answer to this question is by increasing carbon dioxide and decreasing oxygen.

Explanation:

Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.

In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.
