Sometimes individuals at one extreme of a phenotypic distribution are favored in a particular environment, for example, selection will strongly favor insects that have very high resistance to an insecticide. In such cases, the type of selection that operates is

Answers

Answer:

directional

Explanation:

We define directional selection as a type of natural selection whereby a phenotype is favored in preference to other phenotypes hence, the entire allele in the population will tend to shift in that particular direction .

This is clearly demonstrated in a scenario whereby insects that have very high resistance to an insecticide tend to survive better in an environment compared to other insects that do not exhibit this phenotype.

The water cycle is a closed system, meaning no water enters from beyond the system nor leaves the
system. What does that say about the importance of keeping water on Earth free from pollution?

Answers

Answer:

there are no possible changes adaptations

Explanation:

what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out

If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

What is groundwater?

Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.

The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.

Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

In some cases, people who test positive for genetic testing can receive preventive treatments. For example people who test positive for the breast cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast removal surgery) before they develop the disease. In other cases, no preventive treatments are available, but frequent monitoring can help detect a disease earlier, when it's more easily treated.

What ethical or professional concerns does a health-care professional need to address when he or she has a patient who wants to prematurely treat a genetic disease? Do you think genetic testing should be part of normal preventive healthcare? Why or why not.​

carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions

helium ------ mostly escaped Earth's atmosphere due to it is light mass.

Explanation:

Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.

This is very common in mountainous and steep regions, without vegetation cover, where erosion caused by runoff is very high.

Factors that could affect the current oxygen and carbon dioxide levels?

Answers

Explanation:

There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:

Burning of fossil fuels increases the level of carbon dioxide.

Cleaning agricultural land increases the level of carbon dioxide.

The availability of nutrients in plants affects the synthesis of oxygen.

The intensity of the sunlight can increase or decrease the synthesis of oxygen.

Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.

The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.

An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.

A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.
