Which of the following explains why geological events occur?

a The lower mantle is solid rock
b The crust is the same thickness throughout
c The crust is a single layer throughout
d The lower mantle is hotter

Answers

Answer 1
The lower mantle is hotter
Answer 2

Answer:

Hey there,

The answer is A.

This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.

They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.

It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.

It is not C as the mantle is semi molten not solid.

And it’s not D because it’s not a single layer but multiple layers.

So A is the answer.

I hope this helps!

One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell.

In humans blood type A and B are equally dominant (codominant). Both types are dominant to type O. Aman with type AB blood marries a woman with type O blood, give the genotype and phenotype of all possible offsprings

Answers

Answer:

The correct answer would be -

Genotype: IAIO or IBIO

Phenotype: A Blood or B Blood

Explanation:

Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.

The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:

gametes: Aman = IA and IB

woman = IO IO

then cross between:

    IA     IB

IO IAIO IBIO

IO IAIO IBIO

the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

Yeast is added to bread dough before baking. After several minutes, the bread dough rises. Use your experiment to explain how respiration of yeast is important for the baking process.

Answers

Answer:

The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.

While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

Make a yeast-air balloon to get a better idea of what yeast can do

Yeast is a unicellular fungus which undergoes anaerobic respiration to produce ethanol and carbon dioxide gas.

How does yeast fermentation work in bread-making?In a process known as fermentation, yeast consumes the sugar present in the dough to produce carbon dioxide and alcohol.The dough is kept in a warm area throughout the baking process.Fermentation occurs as a result of heat.However, if the temperature is too high, the yeast is killed during the cooking process.As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. The expansion of carbon dioxide during baking allows the bread to rise higher. During the bread-baking process, the alcohol created during fermentation evaporates.

This is how yeast fermentation plays a vital role in the baking process.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.

What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.

D.

Answers

the answer is A
i dont really know how to explain but this was a queen in my test and this was the right answer

The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

What is the organ system?

The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.

Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Answer:

Minerals being deposited as water drips.

Explanation:

Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.
