How does the lipid portion help maintain water concentration on each side of the bilateral?

Answer:

Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?

It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

Novosadov [1.4K]

Answer:

The correct answer is -  b. Responsible for the formation of ATP

Explanation:

The cell membrane is the outer membrane of all types of the cell including eukaryotic, and prokaryotic cell. The cell membrane surrounds the cytoplasm and cell organelles.

The cell membrane is made up of phospholipids that have a hydrophilic and hydrophobic region in the lipid bilayer. The main function of the cell membrane is to protect the cell, provide support, and regulation what enters and leaves the cell. ATP formation is not produced by the cell membrane.

In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). A black male guinea pig is mated to
Virty [35]

Answer:

Male: Bb

Female: bb

Explanation:

1. I made punnet squares to test each genotype pairs:

BB (black male) x bb (white female)

Bb (black male) x bb (white female)

** B is dominant over b so if Bb, black will be expressed

3. I calculated the percentage of each phenotype to see if it matched the the number of white and black guinea pigs produced. I found that Bb x bb had 50% chance for white guinea pigs and 50% chance for black guinea pigs, which is about the same in the scenario above (7 black, 6 white).

4. I infered that the male black guinea pig's genotype is Bb and the female white guinea pig's genotype is bb.

“The movement of cytoplasm is due to the movement of chloroplasts in the living cells of onion plant”, “while the movement of ch
Tpy6a [65]

''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.

The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.  

All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.
