Answers

The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons). In this case the mass number would be 11

Explanation:

Yes

Answer:

B. Using negative feedback to increase its internal temperature when it falls below its normal range

Explanation:

The question asked about INTERNAL temp and how its stbalized, we know that MOST to ALL of negative feedback is getting the organism to return to its original state, high body temp was its original state, therfore,Using negative feedback to increase its internal temperature when it falls below its normal range, is the correct answer.

Pay attention to what happens to the things around you as you go about
your day. Describe three examples of Newton's third law in action (use
different ones from those described in the lesson). In your examples
describe the action and the equal and opposite reaction.

Answers

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices. Two other examples are: As a professor paces in front of a whiteboard, he exerts a force backward on the floor. A car accelerates forward because the ground pushes forward on the drive wheels, in reaction to the drive wheels pushing backward on the ground.

Explanation:

A certain species of fish (A) preys on a smaller species of fish (B). The smaller species of fish mostly consumes seaweed. What would be the effect of overfishing species A? If species A is overfished, then the drop in population of species A will have a(n) (direct, indirect or cascading) effect on the population of species B. The population of species B will increase. A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.
​

Answers

Answer:

B. The population of species B will increase, A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.

Explanation:

As population of Fish A is directly dependent on population of fish B and population of fish B is dependent on seaweed. Overfishing of species A will have a direct effect on species B and population of species B will increase as there will be less predator (species A).

Due to overfishing of species A resulting into increase in species B, there will be an indirect drop in the seaweed, because the larger population of species B would consume more seaweed.

Hence, the correct answer is "B".

Which statement best describes the energy flow as it passes from producers to tertiary consumers?
A. 10% of the energy is transferred through each trophic level.
B. 100% of the energy produced passes to each trophic level.
C. 50% of the energy produced is transferred through each trophic level.
D. 1% of the energy is lost as heat is transferred through each trophic level.

Answers

Answer:

The answer is A

Explanation:

At any given trophic level, only 10% of the energy is transmitted to the next level; the remaining 90% is primarily wasted as heat during metabolic activities. Thus, option A is correct.

What is the role of energy flow in an ecosystem?

Typically, only 10% of energy is transmitted from one trophic level to the next. This restriction on the number of trophic levels that an ecosystem may support is referred to as “the 10% rule.” organisms that are alive and the energy they hold.

Each trophic level's energy content diminishes as it progresses through an ecosystem.

The 10% Rule states that only 10% of the energy will be transferred when it moves from one trophic level to the next in an ecosystem.

Therefore, An energy pyramid provides a graphic representation of energy loss at each level of the feeding stages of species in an ecosystem.

ATP is produced in all stages of cellular respiration. Which two statements describe the process of ATP synthesis in the electron transport chain?
A. The ATP synthase spins when the hydrogen ions rush past, acting as a "matchmaker" and grabbing another phosphate group to attach to an ADP molecule.
B. The high concentration of NAD+ acts as a catalyst to speed up the formation of ATP from ADP.
C. The high concentration of hydrogen ions in the intermembrane space allows them to diffuse across the membrane into the matrix.

C. The high concentration of hydrogen ions in the intermembrane

Explanation:

Merry Christmas

The two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.

What is the significance of the hydrogen in the electron transport chain?

In this electron transport chain process of cellular respiration, electrons are passed from molecule to molecule through a series of protein complexes in the inner membrane of the mitochondria, where ATP synthase is an enzyme located in the inner membrane that makes ADP into ATP.

Hence, the two statements that describe the process of ATP synthesis in the electron transport chain are: "ATP synthase spins when the hydrogen ions rush past, and high concentrations of hydrogen ions in the intermembrane space allow them to diffuse." These are options A and C.

How would a small, uncharged lipid move across the cell membrane?
o through simple diffusion, down the concentration gradient
O through simple diffusion, against the concentration gradient
o through facilitated diffusion, down the concentration gradient
O through facilitated diffusion, against the concentration gradient

Answers

Answer:

Through simple diffusion, down the concentration gradient.

Explanation:

The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

Answer:
