Which of the following is an ecologist most likely to study?
there most likely to study about the environmental systems.
What can cause
carrying capacity to
change?
Answer:
Population size decreases above carrying capacity due to a range of factors depending on the species concerned, but can include insufficient space, food supply, or sunlight. The carrying capacity of an environment may vary for different species.
Explanation:
While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play

Is bacteria a living thing
Answer:
Yes
Explanation:
"Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts.Bacteria are the most abundant of all organisms."
Answer: Yes, bacteria is a living thing
Explanation:
which theory states that homo sapiens began in a single geographical area and spread out from there?
a. out of africa theory
b. tectonic theory
c. multi-regional theory
Answer:
The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.
Explanation:
A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.
B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.
C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.
when a raw, shell-less egg was placed in sugar solution the egg shrank the egg was brought back to its original size by placing it it water which process does the experiment demonstrate
Answer:
A: osmosis. The egg first expanded because it was placed in a hypertonic solution (sugar water), causing the water to exit the egg to balance the higher concentration of solute outside of the egg. Placing it in fresh water creates a hypotonic environment, thereby causing water to rush back in.

Which detail from the passage best explain why plants photosynthesize?
Answer:
B.
Explanation:
I am pretty sure that is the answer
Answer:
A
Explanation:
When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allowed to enter the container. After 24 hours the container is opened, and there is still no gas. Upon tasting the mixture there is a tart flavor. What type of respiration were the bacteria most likely carrying out?
A.
photosynthesis
B.
alcoholic fermentation
C.
lactic acid fermentation
D.
aerobic cellular respiration
Answer:
When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).
Explanation:
The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:
Streptococcus is in charge of removing the oxygen from the milk product.Lactobacillus promotes the conversion of lactose sugar into lactic acid.This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.
Other options are not correct because:
A. Photosynthesis : is the process that occurs in plants to obtain chemical energy from sunlight.
B. Alcoholic fermentation: in this chemical process alcohol is obtained from the fermentation of a sugar.
D. Aerobic cellular respiration: does not involve fermentation, but the series of processes that convert glucose into energy.

Each eye has its own objective in the dissecting microscope so that 3D objects can be seen as 3D, whereas the compound microscope has two oculars, but only one objective for both eyes. 3. Compound Microscopes have greater magnifications, but lower resolutions than the Dissecting microscopes.
China's economy is growing very quickly and requires a large amount of energy. Most of the energy consumed by the country comes from a nonrenewable energy source. Which of the following is a nonrenewable energy source?
A
coal
B
hydroelectric
C
solar
D
wind
Fun fact ; I made this sentence while brushing my teeth , you can tell with how this sentence is lowercased and multiple typos
Answer:
A non-renewable source of energy is coal.
Explanation:
The mineral coal is a brown or black rock, of sedimentary origin, that comes from organic matter, so it is considered a fossil fuel.
Currently, coal is used as an energy source, since its combustion produces a great amount of heat. However, the speed with which coal is consumed is faster than its production —which can last millions of years— so it is considered a depletable or non-renewable energy source.
The other options, such as hydroelectric, solar and wind energy are renewable energy sources.

Which class of biomolecule do the molecules in the table belong to?
Answer:C. Proteins
Explanation:
Just had this question and got it right !
If you place a red blood cell in a solution and it swells, this means that: (Choose all correct answers)
the solution was hypertonic to the inside of the cell
the concentration of water was lower inside of the cell than outside
the concentration of water was higher inside of the cell than outside
the solution was hypotonic to the inside of the cell
the osmolarity of the solution was lower than inside the cell
the osmolarity of the solution was higher than inside the cell
Answer:
The solution would be HYPOTONIC. The concentration of water is higher inside the cell
Explanation:
Hypertonic: cell shrink
Isotonic: cell will stay the same
Hypotonic: cell will swell
