Answer:
Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins
Explanation:
Nucleus has genetic material (DNA) inside it, so it commands the cell about how it has to be function......
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
<h3><u>Answer;</u></h3>
D) it lacks a nuclear membrane and resides inside the nucleus
<h3><u>Explanation;</u></h3>
- <em><u>Nucleolus is a type of cell organelle that is located in the nucleus of an tom. </u></em>Nucleus is the control center of an atom, it controls all the cellular activities taking place in the cell.
- <em><u>Nucleolus is made up of ribosomal RNA and proteins. The main function of the nucleolus is to assemble or formation of ribosomes. </u></em>Ribosomes are cell organelles that are found in the cytoplasm either attached on the endoplasmic reticulum or freely floating in the cytoplasm, where the process of protein synthesis takes place.
