Organisms obtain energy by breaking down food during a chemical reaction. Which substance reacts with the food in the chemical reaction?
A. carbon dioxide
B. chlorophyll
C. oxygen
D. water
Answer: carbon dioxide
Explanation:
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis.
During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light energy.
Answer:
For sure not Carbon Dioxide...

Sea anemones can reproduce sexually or asexually. What would be the most likely advantage a sea anemone would have to reproduce sexually over reproducing asexually?
Answer:
Re-producing sexually will allow the sea anemones to give their offspring a more diverse gene pool and can mitigate the risks of a genetic disorder being spread to the offspring because the bad gene has a higher chance become recessive if the gene of the anemone it mates with is more dominant (meaning it wouldn't allow the "bad" gene to show in the offspring) whereas otherwise, the offspring would have the same issues the mother did (assuming it had a bad gene to begin with).

Which of the following factors limits the abilities of populations within an ecosystem to survive?
A. The frequency of reproduction of each species
B. The number of organisms becomes too large
C. Availability of space, shelter, food, and water
D. Availability of a diversity of species
Please Help! ☹️
Answer:
c
Explanation:
Availability of space, shelter, food, and water can determine the population of animals and plants. If there's an abundant supply of those items species can thrive but if those items are scarce the species in that area can decrease.
The availability of space, shelter, food, and water is a limiting factor for the population within an ecosystem to survive. Therefore, option C is correct.
What are the limiting factors of a population?A system variable that noticeably alters output or another system-related metric is said to be a limiting factor. The limiting factor is made up of organisms arranged in a pyramid from producers to consumers and so on.
Anything that limits the size of a population and slows or prevents its growth is referred to as a limiting factor. Biologic factors including food, mates, and competition with other species for resources are some examples of limiting constraints.
These elements are scarcely available. As a result, in the ecosystem, species frequently contend for the few resources available. Hence, option C is correct.

Which of the following is an example of the endocrine system maintaining homeostasis?
A. Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response.
B. Discharging an excessive amount of hormones in the blood and not sending a signal to stop production.
C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low.
D. Using sense organs to get information about the outside world and direct an appropriate body response release.
Ans.
Endocrine system is a body system that consists of hormones, a group of glands, and secret those hormones into bloodstream directly to regulate the functions of target tissues or organs.
Endocrine system maintains homoestasis by regulating temperature of the body. When there is a rise in body temperature, the endocrine system sends information from hypothalamus to muscles, glands, organs, and nervous system that help to return the temperature into normal level.
Thus, the correct answer is option). 'passing information about body temperature from the hypothalamus to the sweat glands or muscles.'
