<h2>The correct answer is: B.</h2>

Explanation:

A variety of species become threatened or endangered due to various natural and anthropogenic factors.
Natural factors like climate change, global warming, flood, volcanoes, forest fires, avalanche, earthquake, tsunami etc cause the death of many species of organisms and often cause the extinction of several endemic and rare species.
Man-made factors like habitat destruction, mining, quarrying, deforestation, poaching, etc also has similar impact on species diversity.
Conservation of animals can be defined as the procedure adopted to promote the well being of different species of animals such that they can survive and reproduce to maintain their existence on earth without getting threatened, endangered or extinct.
A Threatened species can be defined as the one which has a high probability of becoming endangered in the near future.
An Endangered species can be defined as the one whose population has reduced to such an extent that the probability of the species to become extinct in the near future becomes exceptionally high.
An Extinct Species can be defined as the one whose last surviving individual has died. The ability of such a species to breed and recover its population gets lost much earlier.
Conservation program carried out for the preservation of a particular animal species includes the protection of their surviving habitat, breeding habitat and also their hibernating habitat.
A particular habitat can be occupied by multiple species of organisms which occupy different ecological niches.
Therefore, conservation of the habitat of a particular species of organism will simultaneously cause the conservation of other species present in the same habitat.
Hence, this would indirectly cause the conservation of other endangered species.

Which of the following can result in a population looking more similar over time and can be described as selection against both

Anastasy [175]

Answer: Disruptive selection

Explanation:

Disruptive selection is a natural selection method, it is also known as diversify selection.

Disruptive selection occurs when natural selection favors both extremes of continuous variation. Over time, the two extreme variations will become more common and the intermediate states will be less common or lost.

belka [17]

Groundwater is defined as the water present beneath the Earth's surface in rock and soil pores and in fractures of rock formations.

<h3>What are Saturated and Unsaturated Zones of Groundwater?</h3>

The saturated zone of groundwater refers to the zone in which pores and rock fractures are filled with water only. The top part of the saturated zone is referred to as the water table.

Unsaturated zone refers to the zone present below the saturated zone and consists of air and water pores. The soils and rocks are also found in this zone. It is not readily available water for human consumption.

Thus, the saturated zone has water, while the unsaturated zone has soil, rock, and air with water.

1. What is biotechnology?

rjkz [21]

Answer:

1: the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.

2: Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms.

3: Genetically Modified Organisms

4: Selective breeding is a form of genetic modification which doesn't involve the addition of any foreign genetic material (DNA) into the organism. Rather, it is the conscious selection for desirable traits.

5:Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

6:The use of genetic engineering and the creation of genetically modified crops has resulted in many benefits for the agricultural world. ... By modifying crops so that they are resistant to diseases and insects, less chemical pesticides have to be used to combat diseases and pests.

7:It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. There are two issues from an allergic standpoint.
