NEED HELP ASAP PLEASE!? (10pts)

Biology

Answer:

The correct answer will be option- water.

Explanation:

The plasma membrane of the cell is made up of lipid molecules (phospholipids) which are amphiphilic or amphipathic in nature.  

This amphipathic nature of the lipid molecules is due to the presence of both hydrophilic- polar head group and hydrophobic-tails. The tails are made up of two fatty acids which prevent the entry of the water molecules in the cells due to which special proteins called "aquaporins" gets embedded in the plasma membrane to transport the water molecules.

Thus, option- water is the correct answer.

A fatty acid has a hydrophobic tail this means that it does not like to come into contact with water, like when oil wont mix with water and satys separate as a layer or blobs under the surface.

Why can two igneous rocks have the same minerals but different names?
snow_lady [41]

Answer:

The rocks may have different textures

Explanation:

If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.

Which part of a DNA molecule is responsible for the direct coding of specific traits in anorganism?
Anastaziya [24]

The part of a DNA molecule responsible for the direct coding of specific traits in an organism is the nucleotide sequence.

<h3>How is a DNA molecule structured?</h3>

The DNA molecule is the biological molecule that stores genetic information in living organisms.

The DNA molecule is made up of three major components in its structure:

  • Five carbon sugar
  • Nucleotide bases
  • Phosphate group

The five carbon sugar is deoxyribose while the nucleotide bases are four in number as follows:

  1. Adenine
  2. Guanine
  3. Thymine
  4. Cytosine

These nucleotides are responsible for the direct coding of specific traits in an organism.

Would a muscle cell be able to produce a functional contraction if it lacked t-tubules?
hjlf

The answer would be no. T-Tubules or Transverse tubules are additions of the sarcolemma that infiltrate into the center of cardiac and skeletal muscle cells. There would be no functional contraction since it would not be capable to communicate or interconnect with the other cells.
