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>

Which behavior can reduce pollution that occurs due to the use of coal?
mixas84 [53]

Answer:

A

Explanation:

Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.

Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and  improving natural lighting indoors.

MrMuchimi
DNA, cell membrane, cytoplasm, and ribosomes.

Both prokaryotic and eukaryotic cells have structures in common. All cells have a cell membrane, ribosomes, cytoplasm, and DNA. The cell membrane, or plasma membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
