About how many times thicker is a
cell wall compared to a cell
membrane?
A. about twice as thick
B. about five times as thick
C. about half as thick
D. up to 100 times thicker

Answers

Explanation:

I think it's up to 100 times

A barrier enclosing the cell, the cell wall is located outside the plasma membrane. The plasma membrane can be up to 100 times thinner than a cell wall, hence option D is correct.

What is a cell wall?

Cellulose, a polysaccharide sugar that gives the cell wall strength, makes up the majority of its composition.

The leaf blades of L. perenne and T. repens and the stems of Z had the thinnest cell walls (0–9 m) and the thickest (2–0–3 m) among the cells classified as thick-walled.

Compared to gram-negative cells, gram-positive cells have substantially thicker cell walls. The typical thickness of the gram-positive cell wall is 20–80 nm, whereas the typical thickness of the gram-negative cell wall is 5–10 nm.

Therefore, the cell wall is up to 100 times thicker compared to a cell

membrane, hence option D is correct.

if your leg was to get cut off where would you feel the pain?

Answers

The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.

Hope it helps you... pls mark brainliest if it helped you

Answer:

The nerve(s) in your leg.

Explanation:

It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?


Answers

Hey there! I'm happy to help!

Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.

You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.

Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.

Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.

Answers

Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.

The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.

Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.

The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.
