What would happen if u place a cell in a container of water with high solute concentration?
Dmitriy789 [7]

Answer:

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. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out. There are, however, many cases in which net flow of water occurs across cell membranes and sheets of cells. An example of great importance to you is the secretion of and absorption of water in your small intestine. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name - osmosis.

DNA wrapped around histone proteins forms a material called ____ which condenses tightly to form _____ that can be seen with a l
makkiz [27]

Answer:

The correct answer will be-

1. Nucleosomes

2. Chromatin

3. Sister chroamtid

4. Centromere

Explanation:

The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.

The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.

The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.

The hypothalamus regulates the ________.
Tresset [83]

Answer:

c. pituitary gland

Explanation:

The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.

It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.

It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of  endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.

<u>Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.</u>

Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

Plants convert light energy into chemical energy (glucose). Plants also
DerKrebs [107]

True, plants undergo cellular respiration because they need ATP.

Plants are known as primary producers in the ecosystem because they are able to directly harness the energy from the sun and convert it into complex energy molecules. This process requires ATP.

On the other hand, plants also undergo cellular respiration which is the process by which ATP is produced because the plant also needs ATP to perform the functions of cells.
