At night, the concentration of carbon dioxide in the air in a forest is high. What is the main reason for this?
Answer:
The main reason the concentration of carbon dioxide in the air in a forest is high is due to the increase in plant growth.
Explanation:
Plants release carbon dioxide because of the process of respiration in which plants take in oxygen and give out carbon dioxide. During the day, carbon dioxide enters through the tree's pores, making oxygen escape (and is consistent with the “reverse lungs” concept).
On the other hand, at night, oxygen enters through the pores, and carbon dioxide escapes, rather than oxygen.
The main reason that the concentration of carbon dioxide in the air in a forest is high as there is only respiration going on at night and no photosynthesis.
What is plant respiration?While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots breathe air slowly.
Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.
Plants produce glucose molecules during this cellular respiration process by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.
Therefore, only respiration occurring at night is the reason for a high concentration of carbon dioxide in the forest air at night.

what role do variations have in the theory of evolution by natural selection?
Answer:
variation means that some individuals have traits better suited to the environment than others. so in natural selection everyone's adaptions and traits are different and variated. not everyone is gonna have the best adaptation, that would make everyone op.

2. How does Carbon get into animals (like humans and dogs and such)?
A They gain carbon through photosynthesis
B They gain carbon by eating it.
C They gain carbon by breathing it in.
D Trick Question! There is no Carbon in Animals!
Answer: D, Trick Question! There is no Carbon in Animals!
Explanation:
We don't breathe in carbon we breathe in oxygen and breathe out carbon.
Photosynthesis only happens in plants.
Carbon dioxide is a gas and you can't eat it.
Answer: The correct answer is B They gain carbon by eating it.
Explanation: When animals eat food, they are ingesting carbon in the form of carbohydrates and proteins. In addition, plants produce carbon during photosynthesis for plant growth. When animals eat the plants, they ingest carbon from those plants as well.

in a greenhouse you can control the temperature, light intensity, and carbon dioxide level in order to make it the what factor in photosynthesis
Answer:
Limiting factor
Explanation:
A limiting factor is simply anything in short supply that prevents a reaction from occurring at its maximum rate.
In a greenhouse you can control the temperature, light intensity, and carbon dioxide level which are the limiting factors in photosynthesis for the production of glucose.
What is limiting factor?A limiting factor is a variable that produce a change in output of a process or a chemical reaction. Every process has its limiting factors which bring a change in it.

C. water changes pH as it warms.
D. overfishing is changing the structure of ecosystems, haring the plankton that regulate the pH of ocean water.
E. acid rain has worsened over the last two decades.
Answer: b
Explanation:
Its b because Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.

after fertilization a single cell divides successfully to form a multicellular structure what happens next in order for this structure to develop tissues and organs to meet the needs of the organism
Answer:
After fertilization, a single cell divides successfully to form a multicellular structure. What happens next in order for this structure to develop tissues and organs to meet the needs of the organism? The cells undergo differentiation into particular body parts.
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).
