What is an alternative stable state? the first species to grow after a severe disturbance after a disturbance, a stable communit
Dima020 [189]

Answer:

In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.

Explanation:

  • An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.  
  • The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.

Use the Punnett square to predict the genotype for the parent organism whose genotype is unknown and
Katyanochek1 [597]

Answer: The genotype for the parent organism whose genotype is unknown is Ff.

Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.

The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).

A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).

Ff x ff = Ff, Ff, ff and ff.

Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

Ivahew [28]

The correct answer is A. Experimental group

Explanation:

In experiments, the experimental group refers to the group of subjects that receives special treatment or in which the scientist or researcher intervenes. This is the opposite of a control group that does not receive treatment and therefore, it is used as a reference to measure the effect of the treatment.

This implies, in the experiment presented Group A is the control group as they do not have special treatment because they sleep normally and Group B is the experimental group as the researcher modifies their sleep time and reduces it two hours which means in this group there is a treatment or intervention.

The outer hair cells respond to sound by slightly tilting and changing length. because of the consequence of this, the action of
serg [7]

Basilar membranes

In an active cochlea, basilar membranes vibrate more strongly than in a dead cochlea. because all of the outer hair cells slant significantly and alter in length in response to sound. In response to basilar membrane changes, outer hair cells swell and contract. The frequency tuning curve is impacted by damage to the outer hair cells.

<h3>What are the function of Basilar membranes?</h3>

The basilar membrane is the inner ear's primary mechanical component. Over its length, it has graded mass and stiffness characteristics, and its vibration patterns separate incoming sound into its component frequencies, which trigger various cochlear areas.

Impact do outer hair cells have on our hearing :

As a nonlinear amplifier that enables the cochlea to detect sounds with great sensitivity and accuracy, outer hair cells (OHCs) play a crucial role in hearing. These distortion products can be monitored as distortion-product otoacoustic emissions as a result of the nonlinear sound processing (DPOAEs)
