An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

REY [17]

Neurosecretory cells make and release the hormones from the posterior pituitary. The cell bodies of these neurosecretory cells receive synapses from Afferent neuron and their axon terminals release hormones into blood stream or the local extracellular space.

Neurohormone is  generally produced by neurosecretory cells and liberated by nerve impulses. Neurosecretory cells receive synapses from afferent neurons to guide magnocellular neurons .

A synapse is known as a  small junction at the end of a neuron that allows any signal to pass through one neuron to another. Synapse is a junction were the one neuron get connected with the other neuron .

What do the following two equations represent?<br> 5x +y = 3<br> . 10x + 2y = -6
cupoosta [38]

Answer:

Choose distinct parallel lines.

Explanation:

They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.

y = - 5x + 3           The slope is - 5

10x + 2y = - 6        Subtract 10x from both sides

2y = - 10x - 6         Divide by 2

y = -10x/2 - 6/2

y =-5x - 3

That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.
