Answer: A
Explanation:
(A) A mutation is a small-scale change in the nucleotide sequence of a DNA molecule. A point mutation is shown but there are several other types of mutation, ... Replication errors can also lead to insertion and deletion mutations ... on function, but longer extensions might interfere with folding of the protein and so result in ...
2 The body has to always maintain a constant internal environment. For example, the hormones
aldosterone and antidiuretic hormone (ADH) help regulate the balance of bodily fluids by causing the
kidney to excrete or retain fluids and electrolytes. This constant regulation of hormones and bodily fluids
to maintain balance is an example of which cellular process?
F) Active Transport
G) Negative Feedback
H) Positive Feedback
J) Homeostasis
Answer:
H
Explanation:
I am not 100% sure but that seems like a reasonable answer
Answer: J
Explanation:Homeostasis takes place in order to maintain a balance.

0 D. Light waves
TRUE OR FALSE: The molarity of a flaccid plant is equal to the molarity of the solution. The molarity of a turgid plant is greater than the molarity of the solution. The solute potential of a turgid plant is lower than the solute potential of the solution. The molarity of an plasmolyzed plant cell is greater than the molarity of the solution.
Answer:
1. The first statement is true because water movement takes place until it reaches an equilibrium.
2. The second statement is false because the concentration inside the cell will be greater until water moves inside the cell.
3. The third statement is true because solute concentration is high outside.
4. The fourth statement is true because it loses water in a hypertonic solution.

42 is the correct answer
Answer:
42 is the answer to 6 x 7
Explanation:
Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
lung cells
skin cells
heart cells
Answer:
skin cells.
Explanation:
for connexus friends
The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.
The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.
Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.
Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

If the function of an aquaporin is inhibited, how would the transport of water into the cell be affected? (3 points)
A. Water molecules will no longer be able to cross the cell membrane.
B. Water molecules will move across the cell membrane at a much slower rate.
C. Water molecules will only be able to cross the cell membrane by active
transport
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
Answer:
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.
What is the function of Aquaporin?The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.
Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.
If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.
Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

You want to alter this model so it also shows the flow of energy through the biosphere. To start, you draw a sun. Then, you draw arrows from the sun to the trees and the photosynthetic algae, which are examples of . From there, arrows would be drawn to the moose and the fish, which are . Finally, you would draw arrows connecting groups to , which are represented by microbes responsible for decomposition on this model.
Answer:
The correct answer is :
1. Autotrophs
2. Heterotrophs
3. Saprophytes
Explanation:
In a flow of energy through a biosphere, organisms that trap sunlight for producing their energy on their own known as autotrophs such as plants and photosynthetic algae. These organisms are able to produce their energy and food on their own.
The moose and the fish are the organisms, depends on another organism for their food which means they are heterotrophs and these organisms only get 10% of the energy of what they depend on.
Plants and animals when dies or dead organic matter are decomposed by various microorganisms known as saprophytes to get their energy.

What is the difference between diffusion and facilitate diffusion
Answer:
Diffusion is the passage of molecules from a high-concentration region of the molecule to a lower-concentration area of the molecule.
Facilitated diffusion is the passage of a molecule with the assistance of a protein channel or carrier from a region of high concentration to an area of lower concentration.

1) State whether plants perform cellular respiration and explain why or why not.
2)Explain which cell would likely contain more mitochondria, a muscle cell or a skin cell. Use your knowledge of energy; mitochondria and their function to support your answer.
Answer:
1) plants use photosynthesis to produce glucose, but the use cellular respiration to release energy from glucose so yes they do perform cellular respiration
2) a muscle cell because mitochondria is the site of cellular respiration (releasing energy from glucose) and they need more energy for muscle contraction

A seismograph station is located several thousand kilometers from an earthquake’s epicenter.
Explain the order that the S and P waves will arrive at the station.
By using the characteristics of the S and P waves explain why they arrive in the order they do.
Answer:
The P waves will arrive at the station first because they travel the fastest at an average of 6.1 km/s. The S waves will arrive second, traveling slower at approximately 4.1 km/s. The two different waves would have arrived 3 minutes apart, based on the S-P Wave Interval Chart.
Explanation:
Answer:
The P waves will arrive at the station first because they travel the fastest at an average of 6.1 km/s. The S waves will arrive second, traveling slower at approximately 4.1 km/s. The two different waves would have arrived 3 minutes apart, based on the S-P Wave Interval Chart.

Answer:
Herbivore
Explanation:
The grasshopper eats grass and does not seem to eat anything else in the food web, so it is a herbivore. Herbivores are organisms that eat plants, and since the grasshopper furfills this definition, therefore it is a herbivore. It is not a carnivore because carnivores do not eat grass. It is not a decomposer because it does not break down dead material. It is not an omnivore because it does not eat both plants and animals.
