Answer on e2020 environmental science -

One likely future change is an increase in the overall global temperature due to global warming caused by an increased concentration of greenhouse gases in the atmosphere. This change could lead to other effects such as an increase in sea levels, a decrease in resources, an increase in disease, and ocean acidification.

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

A derived trait of land plants is the presence of small openings that allow gaseous exchange between the plant and its environme

mel-nik [20]

Answer:

B. stomata.

Explanation:

Stomata are openings in the surface of the plant epidermis through which gases and water vapor pass. They are formed by two elongated cells whose shape is similar to bean grain or dumbbell depending on the species. These cells are called guard cells, and in their midst there is a slit called the ostiole.

The stomata make the exchanges between the external and internal environment of the plant. They regulate the size of the opening, so it is possible to increase or decrease the rate of perspiration of the plant.

Stomata are usually located at the bottom of the leaf, but in aquatic plants such as the water lily they are at the top and still in vertical growing plants on both sides.

5. The F2 generation of a cross between a parental tall and a parental short pea plant is 298 tall plants and 102 short plants.

Vadim26 [7]

Answer:

The answer is XX.

Explanation:

Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous to have the short phenotype which means it needs to have the genotype xx or Xx.

The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.

I hope this answer helps.

Which action explains how a somatic cell mutation can harm an organism

wel

Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.

Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.
