The amoeba excretes waste through _________ while a sparrow excretes waste through __________.
Answer:
The amoeba excretes waste through Contractile Vacuole while a sparrow excretes waste through Cloaca.
Explanation:
In some unicellular eukaryotic organisms (e.g., amoeba), cellular wastes, such as ammonia and excess water, are excreted by exocytosis as the contractile vacuoles merge with the cell membrane, expelling wastes into the environment.
Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.

can someone make a story about calcium? pls help me
Answer:
um a story about Calcium? sure... Pls mark me brainliest!
Explanation:
Calvin Calcium was strong. Calvin Calcium was sturdy. Calvin Calcium had very good teeth. He
was a happy little boy and drank all of his Phenyl-Free. But one day all that changed. Here’s what
happened…
“I’m not going to drink my ‘milk’ any more,” said Calvin one morning at breakfast.
“Oooh,” said his mother, “then you can get your calcium from green, leafy
vegetables.”
“No,” said Calvin, “I’m not going to eat green, leafy vegetables either.”
“Oooh,” said his mother, “what will happen to Calvin?”
It wasn’t too long before Calvin found out.
In May, it was time for Calvin to have his dental check-up.
“Oooh,” said the dentist, “you have four cavities, Calvin. Have you
been eating foods with lots of sugar? Have you been forgetting to brush your teeth?
Maybe you haven’t been eating enough foods that give you calcium.” The dentist
filled the four cavities, and Calvin’s teeth were fine again. Calvin didn’t mind—too
much.
But in July, Calvin and his friends, Fred and Linda, were
building a tree fort.
They were almost done when, whoops, Calvin lost his balance and
tumbled to the ground!
“My arm hurts!” wailed Calvin.
“Oooh,” said his mother, running from the kitchen, “we’d better go
to the doctor!”
Doctor Smith felt Calvin’s arm very carefully.
“Oooh,” said the doctor, “you have a broken arm, Calvin.”
He put Calvin’s arm in a cast, and Calvin couldn’t go out to play for a long
time. He missed splashing in Fred’s pool to get cooled off on hot days. He
missed Linda’s birthday party. They played lots of neat games and had his
favorite low protein foods. But most of all, he missed playing with his friends.
He could hear them playing ball and roller skating every day.
Calvin went back to the doctor because it was
taking so long for his arm to heal.
“Oooh,” said the doctor, “it looks as if you haven’t been
eating foods with lots of calcium to make your bones strong.”
The Calvin Calcium Story
One morning Calvin said to his mother, “I’d like some of my ‘milk’ for breakfast.”
So that morning Calvin drank his ‘milk’. It tasted very good.
At lunch, Calvin said, “I’d like some green, leafy vegetables, please.”
So that noon, Calvin had green, leafy vegetables. They tasted very good too.
At dinner, Calvin said, “I’d like some green, leafy vegetables AND some ‘milk’, please.”
So Calvin had collard greens and lots of his ‘milk’ for supper. How good they tasted!
Calvin’s arm was almost healed now. Soon he would be able to join his
friends at the pool, on skates, and in their ball games.
When Calvin went to the dentist that fall, he had only one cavity. Calvin said
he had been brushing his teeth after eating AND eating foods that give him
calcium, especially his ‘milk’.
Calvin was again a strong, sturdy, happy boy—with very good teeth and strong bones!

I don't know what subject this is! But PLEASE HELP ME
Answer:
I belive it would be B
Explanation:
All of the following are advantages of using solar energy except it is a form of coninuous power and it is responsible for it reduces the dependence on fossil fuels. Thus, option B is correct.
What is fossil fuel?
A fossil fuel has been hydrogen that contain the material found in the nature in the earth's crust from the remain of the dead plants and animals that has been extracted and burned as the fuel. Fossil are natural source of energy, it is made from decomposition of plants and animals. Fossil fuels are found in the earth's crust and it must contains carbon and hydrogen which could gives energy by the burning. Natural gas usually found in pockets above oil deposits. It is also found where natural oil is found.
Coal, oil including natural gas are the best examples of the fossil fuels. Coal has been a material usually found in the sedimentary rock deposits where rock and plants are buried from long time. Oil has been originally found as the solid material between layers of sedimentay rocks, like shale. This material has been heated and converted into a gasoline.
Therefore, All of the following are advantages of using solar energy except it is a form of coninuous power and it is responsible for it reduces the dependence on fossil fuels. Thus, option B is correct.

What does it mean when two objects are said to exert a mutual force of attraction?
A. Each takes turns attracting the other. B. They attract each other at the same time.
C. A third object takes turns attracting each of them.
D. A third object attracts them both at the same time.
Answer:
B
It says "mutual", so both objects are attracting at the same time. In addition, I do not believe it is possible for objects to take turn acttracting each other so I believe A is false. I think C and D are wrong because a third object is not related to any of these choices. It also explicitly states "two objects" and when it says mutual, it means they are attracting each other.
