2. It helps prevent the organism from drying out.
3. They help protect the organism from physical damage.
<u>Disadvantages:</u>
1. Exoskeletons must be shed, leaving the organism vulnerable.
2. Exoskeletons cannot grow.
3. Extra sensory organs are required for optimal function.
Hope this was helpful!
Since hydropower is powered by water, it’s a good fuel source. It will not contaminate the air like power plants that release fossil fuels, for example coal and oil. It does not rely on international fuel sources and lets each state make their own energy.
Turtles
Reducing the amount of artificial light that is visible from nesting beaches is the first step to reducing light pollution that affects sea turtles.
Snakes
when snakes are in the sunlight they can gain alot of energy and heat and they can stay warm for a long time.
I dont realy know about the other two
Answer:
A. A water molecule passes through a semi permeable membrane
Explanation:
Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.
In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.
Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.
Answer choice A is correct because the water molecule was able to pass through by itself.
So, the correct answer is A. A water molecule passes through a semi permeable membrane
<span>Cells are basically the building blocks of all living things. There are actually trillions of cells in the human body!
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
I hope this helps you!! :)</span>
