Explanation:
The illustration shows carbon dioxide moving from the atmosphere to the plant. This can only occur through the process of photosynthesis because the process utilizes carbon dioxide and sunlight energy to make glucose (hence storing the carbon in the plant). Plants are major carbon sinks and play a significant role in mitigating global warming by reducing the accumulation of carbon dioxide as a greenhouse gas in the atmosphere

C
Explanation:
Overfishing reduces marine populations because the activity reduces a species' population too drastically to very low levels such as the individuals left are not adequate enough to repopulate the species leading to a spiraling effect of reduced population size and growth leading towards extinction. It is important that Ben ensure that fishing for the shrimp does not reduce the population below this critical point where re-population of the shrimp may become impossible.

A
Explanation:
Logging will enure the current generation benefits from the current natural resources, in this case, the tree. Planting of at least a tree for every downed tree ensures that the young tree will grow and mature and will be utilized by upcoming generations. This ensures a sustainable cycle with each generation benefiting from the natural resources (trees). The other choices are not as sustainable.

Answer:
1. Another word for chemical weathering is b. disintegration
Chemical weathering is a process by which the rocks are broken down into parts and sediments by the action of a chemical agent such as alkali or acid. The disintegration can be a natural process by which a solid body is broken down into parts or subparts.
2. d. moving water is not an agent of chemical weathering agent.
The chemical weathering can be caused by the agents like lichens which secretes acid on the rock surface and causes it's disintegration, acid rain and salt water are chemical agents that can cause the disintegration of the rock but moving water will have little influence on the hard rock surface.
3. c. chemical weathering is a process which turns rocks and minerals into new substances. The chemical weathering process brings change in the chemical composition of the rocks due to the action of the weathering agents hence, on disintegration of rocks new substances are formed.
Large molecules such as hormones materials are expelled from cells during exocytosis
<u>Explanation:</u>
The materials inside the cells are transferred to the outside of the cell and this manner is termed as Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.
For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.
The Crossing Over only occurs in the meiosis on prophase I and metaphase I
Yes sir it will meiosis is my fav part of science
