7 0


The best answer is B.

The cells of a multi cellular organisms are called eukaryotic cells and have:

1. a membrane-bound nucleus

2. numerous membrane - bound organelles including the endoplasmic reticulum, Golgi apparatus, chloroplasts and mitochondria.

3. several rod-shaped chromosomes.

Because a eukaryotic cell's nucleus is said to be surrounded by a membrane, it is said to have a true nucleus.  Organelles (meaning "little organ")  have specialized cellular roles just like the organs of  the body have specialized roles.

What effect would hypotension have on the capillary hydrostatic pressure gradient and net filtration pressure?
Alla [95]

Hypotension will  cause the interstitial fluid hydrostatic pressure to increase and capillary hydrostatic pressure to decrease. The net filtration pressure will be reduced favoring the absorption .

Explanation:

Hypotension refers to reduced blood pressure. Decrease in blood pressure results in reduced filtration pressure on capillary walls. This reduces the filtration of water and solutes into the tissue fluid but will favor the movement of water from tissue to blood. So we can say that net filtration pressure will be reduced.

A car moves with an initial velocity of 15 m s-1 and accelerates with constant acceleration 4 m s-
timofeeve [1]
Initia Velocity(u) :- 15m/s

Acceleration(a) :- 4m/s2

Time Taken(t) :- 50 Seconds

{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}

We Know,

s = ut + 1/2 at2

s = (15*50 + 1/2 *4*50*50)m

s= (750 + 5000)m

s = 5750 m

Therefore distance traveled is 5750 meters.

Hopefully this helps

How would the contractile vacuole of a freshwater amoeba respond is the organism was placed in seawater
morpeh [17]

The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.

In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.
