In plant cells, how are chloroplasts and mitochondria related?

A. Chloroplasts manufacture food;mitochondria break down the food and convert it to energy

B. Chloroplasts package nutrients;mitochondria deliver the nutrients to other parts of the cell

C. Chloroplasts absorb water from the surrounding tissue; mitochondria store water

D. Chloroplasts direct the functions of the cell;mitochondria deliver messages to other parts of the cell.

Answers

Answer:

Explanation:

Answer is A

Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.

Answers

In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.

The percentage of energy transferred to the deer after feeding on the grass is 10%.

The 10% law of the energy states that:

1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.

2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.

Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.

The correct answer is Option C.

Which is a part of the process of speciation?
A. Increased gene flow
B. Interbreeding between species
C. Fixing alleles
D. Divergence

Answers

According to the research, divergence is a part of the process of speciation.

What is divergence?

It is the process of speciation in which two closely related species evolve by changing a common ancestral structure in different ways.

In other words, starting from an ancestral structure, different species evolved by adapting to their environment and their needs.

Therefore, we can conclude that according to the research, divergence is a part of the process of speciation.

solution?
A. Water will exit the cells and cause them to shrink in size.
B. Water will enter the cells and cause them to grow in size.
C. Water will neither enter or exit the cells and their sizes will remain the same.
D. Water will enter and exit the cells at a steady rate and their sizes will remain
the same.

Answers

Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.

Explanation:

Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.
