ok I have like this campaign thing for science so i have to try and get people to vote for the mitochondria so on a slide i have to include the structure and the function of the mitochondria and be sure to relate them it also says it is very important to make the connection with the voters about why the mitochondria is the most important so include why the mitochondria is crucial for survival of your organism so if anyone can help that would be amazing

Answers

Answer:

The mitochondria is the most important organelle because it is where energy is produced through cellular respiration. It serves as an energy source for eating, breathing, moving, and thinking: all basic units of life. If there were no mitochondria many essential functions of the cell could not happen.

Which of the following contribute to the elevated level of carbon in the atmosphere? a. greenhouse emissions b. deforestation c. humans d. all of the above​

Answers

Answer:

d. all of the above​

Explanation:

All of the given choices contribute to the elevated level of carbon in the atmosphere.

This is one of the leading cause of climate change.

Greenhouse emissions from the surface is a huge problem which originates from increasing the release of these gases into the atmosphere. Carbon dioxide is one of the greenhouse gases, and it is the main component of the emissions. Deforestation involves the removal of trees from the earth surface. Trees naturally removes carbon from the environment. They use the carbon to manufacture their own food. Human activities such as industrial processes, burning of firewood for cooking, etc. all contributes significant amount of carbon into the atmosphere.

Could an animal adapted to live in an ecosystem at the bottom of the Rocky Mountains survive in an ecosystem at the top of the Rocky Mountains? Explain your answer.​

Answers

Answer:

No, the environment would be completely different. At the bottom of the mountains there would be certain things that at the top you would not find and vice versa. The oxygen levels would also be different. The most important point is that an animal doesn't adapt easily. For example we humans, we live on the ground if we decided to live on Mt. Everest the lifestyle would be so hard to adapt to because we aren't used to it, like oxygen levels, food sources, temperature, etc. Same thing with this animal.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must do, especially the actual experiment part. You must also list the "controlled variables", the "independent variable", and the "dependent variable

Answers

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.

Explanation:

We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.

Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:

1. We can apply Vitamin C in a form of solution on the ashy skin.

2. Observe the changes on the skin directly and apply for 2-3 times in a day.

3. Observe the changes on the skin after a week.

The fluid-mosaic model of the cell membrane suggests that the membrane is primarily composed of proteins and lipids. Which of the following is a function of proteins in the cell membrane
A to read messenger RNA to assemble amino acids
B. to provide a hydrophilic head so that water can enter the cell
c. to package and sort molecules to be sent in vesicles
D to allow substances to cross the plasma membrane via active transport

Answers

Answer:

B

Explanation:

Protein as amino acids

The fluid Mosiac Model is a theory that explains the structure of the functional cell membranes. The model is characterized by the lipid bilayer, in which protein molecules are embedded.

The correct answer is:

Option B. to provide a hydrophilic head so that water can enter the cell

The functions of protein in the plasma membrane are:

1. The lipid bilayer is amphiphilic, such that they have a hydrophobic and a hydrophilic end.

2. Membrane proteins are involved in the transportation of ions, molecules, or other substances across the membrane.

3. The membrane protein is selectively permeable such that, the aquaporins are the family of proteins, which is involved in the flow of water inside and outside the cell.

Thus, the correct answer is Option B.

Why do two children from the same parents have similar structures but different genetic traits?
The two children receive different combinations of genes from their parents due to meiosis and fertilization.
The two children receive the same chromosomes from each parent due to mitosis and cytokinesis.
The two children grow up in a similar environment but are exposed to different learning experiences.
The two children develop the same mutations in their DNA but do not express mutations that impact physical characteristics.

Answers

Answer:

has to do with the fact that each parent actually has two different sets of genes. And that each parent passes only half of their genes to their child. And that the half that gets passed down is random. All of this together ensures that each child ends up with a different, unique set of genes. Hope it helps!!

Biome

Explanation:

A community might be defined as a group of organisms that coexist in a certain time and space. It can be defined at different scales.

A biome might be defined as a community at a supercontinental scale. It is a group of communities in different parts of the world with the same or very similar physiognomy (referring by physiognomy to the external and characteristic aspect that is seen in an object) .

Biomes are defined in function of the climatic patterns and the groups of plants living there, an ecological classification.

The Everglades are part of a biome. We might find ecosystems, populations, and communities at a local scale, but not biomes.

Answers

Answer:

B. phases

Explanation:

The changing shape of the moon in the sky is called phases.

The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.

How does the Moon's shape seem to alter?

The Moon seems to change shape because we notice distinct amounts of the lit portion as the Moon orbits Earth.

When the Moon is between Earth and the Sun, the lit flank is obscured from us.

As it moves around Earth, the lit flank comes into view. Then it commences and vanishes again.

Thus, The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.
