why is it important to have suberin on epidermis
Explanation:
Suberin functions as a physical barrier, preventing water loss from the tissues it surrounds as well as providing protection against pathogens. It also forms a significant component of the wound healing process in plants; indeed the main model system to study suberin and the suberization process is the potato tuber.

if transcription occurred from left to right, which strand is the template strand?
Explanation:
If the polymerase is moving from left to right, the strand that is oriented from 3' to 5' left to right is the bottom strand. This is the template strand. The top strand is called the coding strand (or sometimes the non-template) strand.

How does the tilt of the Earth and the Earth’s revolution around the sun cause seasons?
Please help.
I might even mark brainiest if the answer is straight forward.
basically if your country is facing the sun it is summer, if its facing away from it, winter. if half, spring or fall. that's why it gradually gets colder or hotter because we slowly spin away or towards the sun.
Q.1: The building in this photo was damaged during an earthquake.
Can we feel plate movement when there isn’t an earthquake?
Q.2: How far do you think a plate can move in one day?
Q.3:How far do you think a plate can move in one year?
When considering plate tectonics and the rate at which tectonic plates move, we can say that daily, the plates will move fractions of a millimeter, which can result in up to a few centimeters yearly, which is why we don't feel this movement when there isn't an earthquake.
Plate tectonics refers to the movements of large-scale plates that make up the earth's lithosphere. Despite their massive size, and very beneficial to us, these plates move very slowly and gradually. The plates can move at rates up to half a millimeter per day, which will result in about 14cm yearly.
This seemingly slow speed is actually among the highest number recorded for plate movements, most in fact will move much slower than that. It is due to this very slow movement speed that we do not feel the movement of plate tectonics when there is no earthquake.

Difference between i) bacteriostatic and bactericidal and ii) broad and narrow spectrum?
Answer:
Narrow-spectrum antibiotics target a few types of bacteria. Broad-spectrum antibiotics target many types of bacteria. Both types work well to treat infections. But using broad-spectrum antibiotics when they're not needed can create antibiotic-resistant bacteria that are hard to treat.

How can some large molecules and charged ions get through the cell membrane?
Answer:
In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.
Some large molecules and charged ions get through the cell membrane as
a result of osmosis, diffusion, facilitated diffusion etc.
Molecules get through the cell membrane through diffusion which is the
movement of substances from a region of higher concentration to a region
of lower concentration.
Facilitated diffusion is the same with diffusion but it makes use of a
substance for transport.

What is excretion and egestion
Answer:
Explanation: Excretion and Egestion Difference
Excretion is the process where an organism excretes the byproduct of a metabolic process using the different cellular and organ functions. Egestion, on the other hand, is the term associated with the excretion or elimination of undigested food from the digestive system of an animal.
Answer:
Basically egestion is when undigested food becomes waste and comes of out the body through the anus, and excretion is when your body removes toxic and waste material and excess products from organisms.

What is this ? Convergent boundary, Divergent boundary or Transform boundary? Explain
Answer:
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
chlorophyll is the main pigment found in plants. other pigments are also present. if these other pigments were lost from a plant, but chlorophyll remained, what effect would this likely have on the plant and why?
Answer:
Chlorophyll is the main pigment found in plants. Other pigments are also present. If these other pigments were lost from a plant, but chlorophyll remained, what effect would this have on the plant? The plant would no longer be able to absorb wavelengths of light distinct from the ones absorbed by chlorophyll.

Should water h20 be included in the model as a reactant or a product
Answer:
The water should be omitted as a reactant or product to have a well-balanced equation only if the water reacts as a solvent.
Explanation:
The water acts as a pure liquid and the increase of concentration of pure liquid is impossible. So, it is of no use when it acts as a solvent. As a product form water can be obtained as a liquid or gaseous substance. Their ability can increase the supply of hydrogen or oxygen to the reaction. When it is used as a main reactant it should be included.
As a role of solvent, it has no use in the chemical reaction. It has insignificant values as a role of solvent so it should be formatted while having the well-balanced equation. There are a lot of examples in which water is not included in the chemical reaction.

Answer:
7) the environment is hypotonic because it is less concentrated than the inside of the cell
8.)the mass would decrease because the stuff inside the cell (which is more concentrated in comparison) would diffuse across the cell membrane into the environment in order to maintain equilibrium
9.) Diffusion in order to maintain equilibrium (moving things across a barrier from a more concentrated area to a less concentrated area in order to have an equal concentration on each side) does not require energy. However, moving matter out of the cell in Diagram C would require energy because it involves moving mass from a less concentrated area to a more concentrated area.
