According to this question, a group of students decides to investigate the loss of chlorophyll in autumn leaves. They collect green leaves and leaves that have turned color from sugar maple, sweet gum, beech, and aspen trees and subject them to analysis to determine their chlorophyll content.
However, it is important to replicate this experiment because it can only be accepted by scholarly societies if the findings are replicable.
Therefore, the students would be advised to replicate their experiment because the findings won't be accepted until it is replicable.

What happened to yellowstone national park when wolves disappeared ?
In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?
Answer:
Explanation:
According to hardy weinberg
p+q=1
p2+2pq+q2=1
p stands for the dominant genotype
q stands for recessive genotype
pq stands for population that are not homogenous i.e not the same
Given that p=0.3
P2=0.09
q=1-0.3= 0.7
q2=0.49
2pq= 2×0.3×0.7
=0.42
Therefore, the frequency of heterozygous population is 0.42
p2+2pq+q2
0.09+0.42+0.49 = 1

describe one advantage prokaryotes have over eukaryotes
Explanation:
Prokaryotes are able to undergo mitosis for cell division, which is faster than meiosis in eukaryotes. This ensures the survival of their species.
As a solute concentration rises, its rate of transport through a membrane increases up to the point where all the carriers are saturated. This point of saturation is called what
Answer:
transport maximum
Explanation:
In the context of physiology, this point of saturation is called the transport maximum. Like mentioned, this is the point in which any further increase in the concentration of a substance no longer results in an increase in movement of that substance across a cell membrane, thus indicating that the carrier of that substance is completely saturated and can no longer complete its function.
Why are ions important to metabolism?
A.) Some enzymes turn ions into substrates.
B.) Some enzymes require specific ions to work.
C.) Ions are not important to metabolism.
D.) Some enzymes break down into ions.
Answer:
Your answer is B
Explanation:
Ions play an important role in the metabolism of all organisms as reflected by the wide variety of chemical reactions in which they take part.
Ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.
What is Metabolism?Metabolism may be defined as a set of methodologies that involves gradual and continuous chemical alterations that take place inside the cell or the body of an individual in order to stimulate the rate of survival.
Metabolism is also characterized as the sum of the chemical reactions that occurs within each cell of a living organism in order to furnish energy for vital processes.
Ions are an inorganic form of molecules that are loosely associated with the enzyme in order to ensure its effective function. Ions like [tex]Na^+, Mg^2^+, Ca^2^+[/tex], etc. are most prevalent.
Therefore, ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.

Is the widely accepted scientific theory that characteristics of a population may change over time, and that current species may gradually give rise to new species.
Answer:
Evolution theory
Explanation:
The evolution theory was developed by Darwin and it is a generally accepted theory that deals with gradual changes in the characteristics of organisms due to their quests to adapt to continuous changes in the environment.
As the environment of organisms keeps changing, the population of the organism keeps adjusting. Individuals that are able to adjust to the changes survive and are able to reproduce while the weak ones gradually die off from the population.
Hence, the entire characteristics of the population is changed with time as a result. The continuous changes sometimes lead to some species within the population giving rise to a new species entirely.

Where should the biosphere label appear in the system model? Use reasoning to explain your answer.
Answer:
Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.
In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.
The biosphere label should be appeared in the system model that contains geological sphere of the earth.
What is biosphere?
It is the one of the sphere that comprise of the geological sphere of the earth like the geosphere, hydrosphere and atmosphere. In this, there should be the existance and the interaction of the living organism.

This question is about the nutritional content of two foods, X and
Y. The diagram shows two burning foods, X and Y, being used to
increase the temperature of water. The temperature of the water
in each test tube is recorded at the start of the experiment, before
the food is set alight. It is recorded again at the end of the
experiment, after the food has stopped burning. The initial mass
of each food and the volume of water should be kept constant in
both experiments. Explain why these should be kept constant.
