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
Answers
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 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
Answers
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.
What can cause
carrying capacity to
change?
Answers
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

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
Answers
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.

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
Answers
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.

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

The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in water. In contrast, glycogen obtained from muscle or liver disperses readily in hot water to make a turbid solution. Despite their markedly different physical properties, both substances are (14)-linked D-glucose polymers of comparable molecular weight. What structural features of these two polysaccharides underlie their different physical properties
Answers
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

4. Jimmy likes to work with his friend Joe in 7th grade science class labs. However, he notices that he tends to get lower grades when he does work with Joe, because he and Joe like to talk about basketball and not science. He's decided to investigate if his science lab grades are higher when he works with Joe or if they're higher when he works with someone else. He has set goals to become a better student, so help him write a hypothesis for his study. a. Manipulated variable b. Responding variable
Answers
Answer:
If Jimmy works better with someone other than Joe, then Joe is a part of the problem of Jimmy getting lower grades.
b responding variable
Explanation:
If, then statements are used for scientific hypothesis's.
In an experiment, there is always a manipulated variable and a responding variable.
In Jimmy's experiment, his aim is to determine whether working with someone other than Joe will lead to an improvement of his grades so he can have a hypothesis that reads thus; "Working with another student other than Joe will lead to improvement of my grades".
In this experiment, the manipulated variable is his study partner while the responding variable is his grades.
