Answer:

The answer is - Biomass decreases as energy is transferred from one level to another.

Explanation:

The options are;

A. Chipmunks and insects can occupy the same niche.

B. As the number of bears in this community increases, the number of chipmunks will increase.

C. Insects are classified as omnivores in alpine meadow communities.

D. Biomass decreases as energy is transferred from one level to another

The answer is D. Biomass decreases as energy is transferred from one level to another

The energy pyramid being referred to is in the attachment below.

Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.

Answer:

It ocurred a selection by allopatric speciation

Explanation:

The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.

It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.

So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.

What type of deafness is present if the bone-conducted sound is heard longer than the air-conducted sound?
NNADVOKAT [17]
The type of deafness that is present if the bone conducted sound is heard longer than the air conducted sound is CONDUCTIVE HEARING LOSS.
Conductive hearing loss refers to the situation where there is a problem conducting sound waves anywhere along the route through the outer ear to the ear drum and the tiny bones of the middle ear.

While mRNA strands are being created a sequence is sometimes miscopied. What is the best possible outcome for the cell should th
8_murik_8 [283]

Answer:

The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done

Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.

Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.

Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
