Answers

Answer:

Through protein synthesis of course...

Explanation:

DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.

Why does evolutionary theory absolutely require the earth to be very
old?

Answers

Answer:

Because it takes time for the animals to adapt to their environment, and change their DNA

Answer:

Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions. However, if we look at it when it's old, we can see that there were many evolutions. I hope this helps!

Why is energy lost in a food chain? *​

Answers

Answer:

Because as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level

Explanation:

Hope that helps!

not all energy is passed from one level of a food chain to the next. Around 90% of energy is lost from heat during respiration, in materials that the consumer doesn't digest, or through movement. Through the undigested materials where the energy is stored It's transferred to decomposers.

An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this?
A
animalia
B
protista
C
bacteria
D
fungi

Answers

Answer:

B protista

Explanation:

The cell is unicellular, so it can not be an animal, which are all multicellular.

It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)

The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs

Therefore, the organism must be a protist, so the answer is B, protista.

Answers

Answer:

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

Where does the H+ come from that makes ATP synthase work?

Answers

Answer:

Electron Transport Chain

Explanation:

Gizmos Cell Respiration

The H+ that's vital in making ATP synthase work comes from the electron transport chain.

The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.

It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.

How many electrons must get passed down the Electron Transport Chain before energy is generated?

Answers

Answer:

4 electrons

Explanation:

Electron transport chain is defined as the series of process in which electron transfer takes place across a membrane. It is consists of enzymes, peptides, and other molecules.

There are 4 electrons that passed down the Electron Transport Chain before energy is generated. These Four electrons further reduce each molecule of oxygen. Oxygen binds with free proton and form water and move across the membrane to form ATP.

Hence, the correct answer is "4 electrons".
