In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of

BartSMP [9]

Answer:

the concentration of misfolded proteins would be higher than normal.

Explanation:

Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.

what role will nature selection most likely have in the frequency of the alleles responsible for the presence of tissue pockets

Jet001 [13]

Answer:

Through natural selection, those organisms which have better adaptations to survive in an environment are able to live and pass on their alleles to their offsprings. Hence, any trait which is beneficial to an organism will be favoured by natural selection.

As tissue pockets is a trait which is required by the shrimps, hence with the passage of time shrimp population having tissue pockets will increase and will be favoured by nature.

alexira [117]

The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. Positive feedback regulation would ensure that the animal completed its transformation.

Positive feedback regulation of prothoracic hormone secretion by ecdysteroids is the mechanism that determines the timing of metamorphosis.

Metamorphosis is the biological process by which an animal develops physically, including birth and hatching, and which involves marked and relatively rapid changes in an animal's body structure due to cell growth and differentiation.

Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, often with changes in diet and behavior.

In case of frogs, and toads, forelimbs are formed under the gill pouch, and the hind limbs are visible after a few days. This is usually followed by a longer phase in which the tadpoles are fed a vegetarian diet.

Tadpoles use a relatively long spiral intestine to digest this food. Recent studies suggest that tadpoles do not have a balanced homeostatic feedback control system until early stages of metamorphosis.

At this point, their long intestine shortens and they prefer insects.
