11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
Answers
Answer:
The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.
These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.
These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.
People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.

How is cytokinesis different
in plants and animals
Answers
Answer:
MAIN DIFFERENCES
- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.
- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.
- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.

Answers
Answer:
function as the powerhouse of cell
Explanation:
we have read the power house of cell as a mitochondria
==========================================================
Explanation:
The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".
The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.
Forces occur in action-reaction pairs.
A. 1st Law
B. 2nd Law
C. 3rd Law
Answers
Answer: C (3rd law)
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.

which nutrients are present in solution x?
Answers
Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. They are used in every process of an organism’s body. Some of the processes are growth (building cells), repair (healing a wound), and maintaining life (breathing).
Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
From these basic nutrients, plants and other autotrophs synthesize, or create, their own nutrients, such as sugars. The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs. People and animals get most of their nutrients from food.
Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.

Which of the following is not one of the seven primary odors humans recognize?
fresh
putrid
pungent
roses
Answers
Answer:
roses
Explanation:
It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3
There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.
Answer:
Fresh
Explanation:
When you look at the chartr, Roses were cconsidered a floral scent, which was listed, then there was putrid, pungent, and 3 others, the only one that wasn't listed was fresh, because often out scent and taste work together to help us find rotten foods, but we find that by smelling putrid scents or pungent scents, rather than fresh scents. Therefor the correct response is fresh

Answer:
The chemical equation which is a model of synthesis reaction is option B
B. H₂O + CO₂ ---> H₂CO₃
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.
A synthesis reaction is illustrated below:
A + B ----> C
In the illustration above, A and B are two chemical substances which serve as the reactants in the chemical reaction. A and B combine with each other to form a product C.
Common synthesis reaction include:
1. The reaction of sodium with chlorine to produce sodium chloride: Na + Cl ---> NaCl
2. The synthesis of Nitrogen (iv) oxide from nitrogen (ii) oxide and oxygen: 2NO + O₂ ---> 2NO₂
3. The synthesis of sulfur trioxide from sulfur dioxide and oxygen: 2SO₂ + O₂ ----> 2SO₃
