Which of the following is true about top predators? Select one: a. They include bacteria and fungi. b. Their removal increases b
Len [333]

Answer:

d. They are often keystone species

Explanation:

Top predators in an environment are the largest predators and sits on the top (apex) of the food chain in an ecosystem which do not have any natural predators.

As the top predators relative to its abundance has disproportionately large effect on its natural environment, they are the keystone species most of the time.

Hence option d. They are often keystone species is the right  option.

Although selection operates against deleterious alleles in populations, they are rarely lost from these populations. For example
KonstantinChe [14]

Answer:

Deleterious alleles appear sporadically in a population

Explanation:

A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.

Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.

What kinds of environmental problems result from population growth in (a) developing countries and (b) developed countries? Whic
Alecsey [184]

Answer:

Environmental problems result from population growth in:

a) Developing countries-

  • Air pollution due to burning of fuels and wood.
  • Water and soil pollution due to improper waste disposal.
  • Improper resource use due to illiteracy etc.

b) Developed country-

  • Overuse of natural resource
  • Deforestation.
  • Air pollution due to increased number of industries and automobiles.etc

Explanation:

A developing country is the one which is economically backward and are still combating poverty and illiteracy.

The major reason behind the population growth is illiteracy and unsafe coitus.

This results in unwanted childbirth.

The second  reason is the want for earning members to support the family.

Increasing population creates an outstanding demand of resources and creates a pressure on environment.

More and more fuels are burned and hence add up to air pollution.

Improper disposal of waste is also a major issue in these countries as most of the people being illiterate are unaware of proper ways of disposing such waste.

A developed country is at the epitome of economic growth.

The major reason behind the population growth in these country is the immigration of people from developing countries.

Being economically advance , these countries can afford best of technologies that make the utmost use of resources available.

Increase demands of settlements, industries and resources has lead to clearing of large  forest lands and deforestation.

Industries and automobiles has added up to the air pollution too.

According to me the effect of population growth in developed countries is a greater threat because these lead to overexploitation of resources by technology. more the population will grow the demand for development will also grow. Thus, this is quite difficult to control.

In case of developing countries, proper education and training will create difference to a greater extent.
