The answer is (d.) Some scientists believe that prions, tiny proteins much smaller than a cell, that can replicate themselves may be living organisms.

Prions are like viruses, they are not alive making statement B to be true. Prions lack the ability to grow and reproduce. they are dependent on the living cells to replicate. Statement A is absolutely correct while Statement C is somehow wrong. According to scientists, the accurate count of cells in a human is 37.2 Trillion.

Hello, people of planet earth, I need help with a question for my friend Steve in science class, here on planet Neptune it is pr
ICE Princess25 [194]
The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction. The paramecium splits in half (fission) just as the ameba does. First the smaller nucleus splits in half and each half goes to either end of the paramecium. Then the bigger nucleus splits and the whole paramecium splits. Occasionally two paramecium exchange material and form a new paramecium. This is called conjugation. 

<span>Conjugation in Paramecia occurs in the following way: </span>

<span>a). The formation of ciliary contacts. </span>
<span>b). Local loss of cilia and formation of narrow contacts between anterioventral somatic cell membranes </span>
<span>c). Formation of small cytoplasmic bridges (which allow for the exchange of molecular components only). </span>
<span>d). Their enlargement enables the cells to exchange micronuclei. </span>

<span>Bacteria exchange plasmid material and the Paramecia exchange micronuclei.

Good luck to Steve! How is it in Neptune? XD</span>

What di eukaryotes most likely evolve from?
otez555 [7]

Answer:

Prokaryotes.

Explanation:

Most of the Eukaryotes most likely to evolve from the Prokaryotes.  Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside  the plasma membrane, which is a thin layer of lipid that completely surrounds the cell.  Prokaryotes reproduce by binary fission method.
