Skin cells are made of proteins, water, and fat. But brain cells are only made up of amino acids, which ca make protein.<span />
The correct option is (D) iteroparous; K -selected
Iteroparous organisms are the organisms that reproduce multiple times.
<h3>
What is Semelparity and Iteroparity?</h3>
- Semelparity and iteroparity are the two different reproductive strategies available to living beings.
- Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
- Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
- There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
Answer:
Integral membrane proteins are permanently embedded within the plasma membrane. They have a range of important functions. Such functions include channeling or transporting molecules across the membrane. Other integral proteins act as cell receptors

Answer:
The similarities in the way barchan and hooked spit forms are:
First, they are formed from sediment or sand movement.
Second, this movement makes them have a peculiar curved form that provides them their major characteristic.
Explanation:
First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.
Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
