if the hawk were to removed from the food chain, which consumer would increase in population

Answers

Answer:

Everything from the hawk's diet

Explanation:

Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.

Light Reactions : ATP :: Calvin Cycle :
a. G3P
b. H2O
c. O2
d. H+

Answers

Answer:

a. G3P

Explanation:

Photosynthesis is the process by which plants synthesize their food from inorganic sources in the presence of light. The photosynthetic process occurs in two stages namely: light dependent stage (light reaction) and light independent stage (Calvin cycle).

The light stage primarily functions to synthesize ATP and NADPH products needed in the Calvin cycle to synthesize sugar (glucose). However, the CALVIN CYCLE produces a three-carbon compound called GLYCERALDEHYDE-3-PHOSPHATE (G-3-P) as one of the precursors of glucose.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

Answers

Answer:

Option D

Explanation:

The complete question is

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

a) Energy was destroyed during certain steps in the experiment.

b) The steps in the experiment required more energy than was available

c) The experiments created energy that was then used up at a faster rate.

d) Some energy was transformed into unwanted heat or sound that was not detected

Solution -

Option D is correct

While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Material produced from living or recently living plants or animals and their metabolic byproduct is?
A) charcoal
B) biofuel
C) biomass
D) MSW​

Answers

Answer:

C) biomass

Explanation:

Hypothesis: If the amount of protein is calculated in three different lipid levels of milk, then whole milk will have the highest level of protein. What is the independent variable in this experiment? Type of protein Amount of protein Amount of milk Type of milk

Answers

Answer:

Type of milk

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment. It is the variable that causes the dependent variable to change.

In this experiment, the hypothesis, which shows the relationship between the independent and dependent variable is stated as follows: IF the amount of protein is calculated in three different lipid levels of milk, THEN whole milk will have the highest level of protein. This shows that the amount of protein is dependent on the TYPE OF MILK used, which is the independent variable.

B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.

Answers

Answer:

C!!

Explanation:

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

What is RNA polymerase?

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
