Answer:
Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction
A researcher found that the wild species of almond trees contains a chemical called amygdalin.
This chemical is converted into cyanide inside the human body and can be lethal. The researcher
found that a single gene mutation in some of the wild almond trees resulted in a variety that no
longer produced the chemical amygdalin. This variety of almond is largely harvested for human
consumption. Based on the study, the researcher claimed that some mutations are beneficial in
nature. Was the claim made by the researcher correct? Why or why not?
a) Yes. The mutated variety of almond was edible.
b) No. Not all almond trees produced seeds that were edible.
c) No. The mutation did not affect all varieties of almond trees.
d) Yes. Almond trees with amygdalin grew only in forests.
Answer:
a) Yes. The mutated variety of almond was edible.
Explanation:
Yes, the claim made by the researcher is considered correct because the mutation removes the amygdalin chemical from the almond so these almonds are now safe for eating. This removal only occur through mutation. Mutation is the sudden change occur in the DNA of cell that leads to different functions occur in the body so we can say that some mutation that is occur in organisms are beneficial.
Please help!!! I don't know how to tell if they self pollinate or not.
Answer:
The first flower can self pollinate because it is open, so the wind will pollinate it.
Explanation: Flower b will not self pollinate because it is not open, so it will not pollinate until a bird or moose or any other animal comes and eats it, then poops it out, so the seeds get planted.

farms that are being compared?
Select one:
O a. Farm A is a free pasture farm for cattle, whereas Farm B is a free-range farm for poultry.
O b. Farm A is a cage-free farm for poultry, whereas Farm B is an industrial poultry farm.
O c. Farm A is a grass-fed pasture for beef production, whereas Farm B is a traditional
concentrated animal feedlot for cattle.
ction, whereas Farm B is a cage
O d. Farm A is a concentrated animal feedlot for beef
free farm for poultry.
Answer:
b. Farm A is a cage-free farm for poultry, whereas Farm B is an industrial poultry farm.
Explanation: the average days in any 12-month period suggest that farm b cages while farm a does not. The antibiotic usages for farm b also suggest it is an industrial (caged) farm because most cage-free and non-industrial farms do not rely on heavy use of antibodies.
The Farm A is a cage-free poultry farm while Farm B is an industrial poultry farm.
Farm A:
The caged day are zero means all birds can move freely in the farm area.They are not eat antibiotics to avoid infection.Farm B:
Most of the time in year, birds are caged. They fed antibiotic to all to avoid infection in the cage.Therefore, the Farm A is a cage-free poultry farm while Farm B is an industrial poultry farm.

Explain why parallax was a problem in proving the heliocentric model of the solar system.
Copernicus himself asserted that the absence of parallax meant that the stars were far beyond the planets. The failure of heliocentrists to detect it proved nothing, whereas a successful detection would be strong evidence for heliocentrism.
What is heliocentric model?The astronomical model in which the Earth as well as planets revolve around the Sun at the center of the universe is known as heliocentrism. Historically, heliocentrism was opposition to geocentrism, which centered on the Earth.
Galileo wanted to believe that his new invention, the astronomical telescope, could assist him in proving that the Sun was the center of our solar system and that Earth was only one of many planets orbiting our star.
Copernicus himself claimed that the lack of parallax indicated that the stars were far beyond the planets.
Failure to detect it by heliocentrists proved nothing, whereas successful detection would be strong evidence for heliocentrism.
Thus, parallax was a problem in proving the heliocentric model of the solar system.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Someone please just explain this question
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..

Please help me I really need help I am having a hard time with this question.
Answer:
I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.
