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
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?
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.

You are building a birdhouse when you cut your finger. Predict which body systems would be immediately involved with your
reaction to the cut.
Answer:
A.
Explanation:
These systems will be involved!
Hope this helps, have a great day.
The nervous system, circulatory system, and integumentary system are body systems involved immediately when you cut a finger.
The integumentary system is the system that groups the natural covering of an organism, for example:
SkinBarkShellThe nervous system is in charge of electrical signals. These signals are those produced by the senses such as taste, smell, sight. Also, they are responsible for sending signals of pain, satisfaction, pleasure, and others to the brain.
The circulatory system is the system in which blood is transported throughout the body for oxygenating and energizing the entire body.
When someone cuts themselves they feel pain (nervous system), blood comes out (circulatory system) and their skin opens and some of its lower layers (integumentary system) can be seen. Therefore, the correct answer is A.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

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

D)
E)
Indiana is home to fossilized
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.
