A student is investigating the process of osmosis. She fills a medicine dropper with red
blood cells. Next, she creates a saline solution that is isotonic to the red blood cells.What will most likely happen to the red blood cells after they are placed in the
solution?
A. Water will exit the cells and cause them to shrink in size.
B. Water will enter the cells and cause them to grow in size.
C. Water will neither enter or exit the cells and their sizes will remain the same.
D. Water will enter and exit the cells at a steady rate and their sizes will remain
the same.

Answers

Answer 1

Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.

Explanation:

Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.

The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?

Answers

Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".

What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.

How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.

Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

The abundance of sodium leak channels in skeletal muscle is ______ the abundance of sodium leak channels in a typical neuron.

Answers

The abundance of sodium channels in muscles is as important as the abundance of sodium leak channels in a typical neuron.

Sodium plays an essential role in the body, this includes important functions such as:

Intervening in the process of muscular contraction.Intervening in the process of interneural communication.

This is possible through sodium channels in cells that allow sodium to enter or leave the cell at very specific times and this causes specific reactions in cells.

In neurons: Sodium channels are abundant and essential because due to the action of sodium signals are passed from one neuron to others.In muscles: Sodium channels are abundant and essential, especially in skeletal muscles. The role is sodium is to contract or relax muscles, which makes movement possible.

Based on this, the presence of these channels in both neurons and skeletal muscles is equally important.

One possible hypothesis for the Protein Synthesis Gizmo could be: "If the availability of amino acids is increased, then the rate of protein synthesis will also increase."

This hypothesis suggests that the amount of protein synthesized by the cell is directly influenced by the availability of amino acids, which are the building blocks of proteins. Amino acids are monomers of protein.

By increasing the supply of amino acids, it is expected that the cell will have more resources to engage in protein synthesis. It causes an increase in the rate at which proteins are produced.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *

Answers

Answer:

Explanation:

22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.

Perimeter equation is L+L+W+W

We know 7.5 is the length (could also be the width, it doesn't matter the order)

The length appears two times, so lets plug it in-

22.6= 7.5+7.5+W+W  , Now you want to combine the like terms so.. 7.5+7.5=15

22.6= 15+W+W

Now subtract the 15 from 22.6

7.6= W+W , there are two W's left so divide 7.6 by 2

7.6/2= 3.8

It is 3.8 m wide
