This statement is false.
<u>Explanation:</u>
If the results are the same, a hypothesis turns into a theory first.
A hypothesis is an assumed statement which may or may not be correct. Special experiments are designed under controlled conditions to find out whether the hypothesis is correct or not. If the Hypothesis is correct, it becomes a theory. A theory is a sophisticated explanation of the results which is further refined to make a law.
Answer:
Organs of excretion make up the excretory system.
They include the :
kidneys-Blood by-products are filtered out by the kidneys and leave the body in urine form. They are part of the urinary system, which also includes the ureters, bladder, and urethra
large intestine-By-products enter the intestine and leave the body in the form of feces
liver- breaks down harmful substances. It's by-products are excreted into bile or blood.
skin-Sweating eliminates excess water and salts, as well as a small amount of urea, a byproduct of protein catabolism
lungs- oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled

Answer:
Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
Explanation:
The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.
Structure X is not living, and structure Y is living. - this is false, both animal and plant cells are living.
Structure X can be found in some human cells, and structure Y can be found in some plant cells. - this is false, the opposite is true.
Structure X is only found in plant cells, and structure Y is found in plant and animal cells. - this is true structure X is the plant cell wall, and structure Y is the cell membrane
Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
