What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?

Biology
1 answer:
monitta3 years ago

Answer:

B. Carrier proteins

Explanation:

Water-soluble materials, such as glucose, amino acids, and ions, need help to cross the membrane because they are repelled by the hydrophobic tails of the phospholipid bilayer. The tails are not hydrophilic.

Endocytosis vesicles are an example of active transport, they require energy to allow large molecules to be taken into the cell through a system of vesicles.

Golgi complex vesicles deliver proteins and other macromolecules outside of the cell from the inside.

Carrier proteins can participate in both active and passive transport across cell membranes. For example, carrier proteins with channels can help molecules cross the membrane passively.

daser333 [38]

Using the theories of the cells, we got that 4 picograms of DNA would be expected in a metaphase in cell of a female if we assume that a g1 somatic cell nucleus in a female myrmecia pilosula contains 2 picograms of DNA.

Mitosis and meiosis are both types of the cell division. Mitosis is the process by which the  most cells in the body divide, involves a single round of cell division, and produces the two identical, diploid daughter cells. Meiosis is the process by which the gametes are produced.

DNA synthesis is the primarily common to both. If already formed, the cardiac tissues and nervous system cells will never replicate their daughter/sister cells either through the meiosis or the mitosis.

Hence, if we assume that a g1 somatic cell nucleus in a female myrmecia pilosula contains 2 picograms of DNA, then the amount of would be expected in a metaphase i cell of a female is 4 picograms.

Anna007 [38]

Answer:

<em>The correct option is D) Diane will have to travel a farther distance to move the chair.</em>

Explanation:

To slide the chair up an inclined path, Diana would have to travel a further distance. While using the ladder to reach the second floor window would have made the distance smaller, but more force would have been required to move the chair through climbing a ladder. Diane would have got easily exhausted for moving the chair across the ladder. Using the inclined path will make the distance farther but as much force would not be required in this process. Hence, the method of using an incline is better.
