Biology

Lelu [443]3 years ago
5 0
Rachel Carson played a key role in the birth of environmentalism in the 20th century.

She became increasingly aware of the harmful facts of insecticide DDT on the environment. This compelled her to write her most famous work Silent Spring and defending herself against attacks from commercial interests.

The book also played an influential part in persuading governments to ban or heavily restrict the use of DDT and similar chemicals that persist in the environment.

Which of the following is NOT a process that drives the carbon cycle?
stiks02 [169]

"Ammonification" is NOT a process that drives the carbon cycle.

<u>Option: B</u>

<u>Explanation:</u>

The organisms circulate carbon-di-oxide in carbon cycle by going through respiration, decomposition, sedimentation, and photosynthesis process but not ammonification. Basically the actual source of nitrogen is agricultural, when a plant or animal passes or an animal disperses waste.

In the remains, bacteria or fungi turn the organic nitrogen back into ammonium, a cycle called ammonisation or mineralisation. Then the micro-organisms generate metabolically required energy from organic nitrogen oxidation into ammonium. Ammonium is then essential for assimilation and absorption into amino acids or for use in other metabolic applications.

Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth
IgorLugansk [536]

Complete question:

Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth on the top jaw. One has small teeth for holding small live prey prior to swallowing. The other species has very large sharp teeth for injuring and killing large prey prior to biting off pieces of flesh for consumption. The above is an example of:

  • Directional selection
  • Analogous structures
  • Character displacement
  • Hybridization
  • Vestigial structures

Answer:

  • Character displacement

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When <u>two competing species coexist, this is because of niche partitioning or niche differentiation</u>.

Differentiation of effective niche is closely related to <u>character displacement.</u>

<u>Character displacement</u> is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species live in the same pond. But to avoid competition and competitive exclusion, species developed different teeth sizes to feed on different prey items.

8. Water has<br> a lot of heat before changing<br> This proporty allows water to<br> temperature.
aliya0001 [1]

Answer:

Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.
