Answer:d)introns; exons

Explanation:Introns are the non-coding portion of the DNA. They do not code for a gene that can be expressed hence the need for them to be removed from the coding genes(Exons). The exons are then joined together after the introns have been removed to create a sequence of amino acids.

Which of the following correctly matches the equilibrium receptor organs to the type of equilibrium it monitors?
Anarel [89]

Answer:

The correct answer is option B. maculae/ static equilibrium.

Explanation:

Maculae are mechanoreceptors present inside the saccule and utricle specialized for the static equilibrium detecting. Maculae use hair cells to find out the movements of the otolithic membrane occurs, which is the surrounding membrane of the macula.

The sense of the position of the head to determine the stability and posture is static equilibrium and it is determined by the maculae.

alukav5142 [94]

The intermediate disturbance hypothesis predicts that species diversity will be highest  when the frequency and/or intensity of disturbances are intermediate

Explanation:

The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
