The mineral is soft.
The mineral is hard.
The mineral has cleavage.
The mineral does not have cleavage.
Answer:
The mineral has cleavage
Explanation:
Cleavage describes the shape of internal planes of weakness between the molecules that make up a mineral, often forming 3-D geometric shapes like cubes and prisms. When a mineral breaks, it will commonly break along these cleavage planes regardless of how hard or soft the mineral is.

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.

The hardest question ever: What is truth?
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!

What condition is required for piles of sediment to become a sedimentary rock?
1. Low force
2. High energy
3. High pressure
or 4. Low temperature
Sedimentary rocks are created by the accumulation of already existing rocks or fragments of extinct organisms on the Earth's surface, hence option 3 is correct.
What is a sedimentary rock?Weathering causes rock fragments to become loose, which are subsequently moved to a basin or depression where sediment is trapped.
Sedimentary rock is created when sediment is firmly buried and gets compressed and cemented. Large boulders to tiny clay particles have been found in clastic sedimentary rocks.
The process of erosion involves moving weathering products from the weathering site, either as solid material or as dissolved components, to finally be deposited as sediment.
Therefore, sediment is any unconsolidated accumulation of solid, weathered material to become a sedimentary rock that requires High pressure, hence option 3 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.

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.

Outline the pathway of a breath of air from the nose to the alveoli.
Answer:
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Explanation:
Mark as Brainliest Answer
Air travels through the following structures on its path to the alveoli (the site of gas exchange): nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles.
What is breathing?The trachea (windpipe), which is further separated into bronchial tubes, receives it from there. Bronchioles are another division of the bronchial tube, the little alveoli structure is where the bronchioles eventually come to a stop.
Through our noses, we breathe air into our bodies, after then, it moves via the larynx, pharynx, and nasal cavity before entering the windpipe, also known as the trachea.
Therefore, air enters both lungs through bronchi that branch off of the trachea.
