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.

In which environment will decomposition occur the fastest?
A. Antarctica
B. The Sahara desert
C. The Arctic Ocean
D. The Amazon Rainforest
Answer:
Antarctica
Explanation:
In general, decomposition is most rapid in well-aerated environments. Most micro-organisms do not function above moisture contents of 30% by volume. At high soil-moisture contents, oxygen becomes limiting and only facultative and obligate anaerobic bacteria can function
Decomposition is the breakdown process of the larger molecule and dead matter into a simpler form. The rate of decomposition will be fastest in the Amazon rainforest. Thus, option D is correct.
What is decomposition?Decomposition is a biochemical process where the decaying and dead organic materials undergo physical and chemical changes to produce smaller and simpler substances.
The process includes the activity of fungi and bacteria (decomposers) to break and split the larger-complex substance. The process will best occur in the Amazon rainforest due to its conditions.
The temperature and atmosphere of the Amazon rainforest are most suitable for the action of decomposers. It has an abundant amount of moisture, oxygen, and moderate temperature to thrive the microorganisms.
Therefore, option D. the Amazon rainforest will have the fastest rate of decomposition.

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.

Name the process that plants and animals use to maintain an inner cellular environment stable
Answer:
homeostasis
Explanation:
Which scenario resembles science but fails to meet the criteria for science?
O Researchers collecting data about the impact of human activities in cities
O An experiment to determine the foods preferred by squirrels
O Water pollution study paid for by an industrial waste company
O Health study repeated by different scientists around the world
The scenario that resembles science but fails to meet the criteria for science would be a water pollution study paid for by an industrial waste company.
One of the criteria for scientific research is objectivity. Scientific research must be objective and free from any form of bias.
There is a saying that he who pays the piper dictates the tune. An industrial waste company financing a water pollution research would definitely not want a report that will indict the company from a business point of view. They will either try to influence the research or report only the findings that will not indict them.
Hence, a water pollution study being paid for by an industrial waste company sounds like anything but science.

Why is replication in science a good thing? (1 point)
O It means more opportunities exist due to new technology.
o It means no questions need to be asked about the findings.
o it means several teams are working to solve a problem.
o It means the results are more likely to be reliable.
NEED HELP!
Answer:
it means the result are more likely to be relialble
Replication in science is a good thing as the results, in that case, are more likely to be reliable. So the correct option is D.
What is meant by replication in science?The scientific claims are considered to be credible if they can be replicated using the same data. Replication means repeating a scientific procedure or a scientific experiment and getting the same results.
The purpose of replication is to obtain advanced understanding by using and confronting the exact same understanding, but by using new evidence.
In an ironic statement, it is said that if the existing understanding is weak, the value of replication will be the highest. A successful replication is evidence of the generalisation of the results obtained by the initial study of the experiment.
Unsuccessful replication means that the result may not be as reliable as previously thought to be.
Therefore, replication in science is a good thing as the results, in that case, are more likely to be reliable.

Why are beakers and flasks not used to measure liquids
Answer:
Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor. They can hold a much larger volume than any of the other types of glassware, however, which makes them useful for mixing solutions.
Explanation:
Answer: Because they do not give accurate measurement
Explanation: beakers and flask are used to hold liquid higher in quantity or volume , so their measurement lines aren't precisely used for measuring nd it wont give u accurate answer EXCEPT u do a guess work or project

How does parasitism differ from other symbiotic relationships?
Answer:
Parasitic symbiotic relationships consist of a parasite and a host. In a parasitical relationship only the parasite receives any benefit from the relationship while the other organism known as the host is harmed. In other symbiotic relationships like mutualism. Mutualism symbiotic relationships is where both organisms benefit and commensalism is where one organism benefits and the other is unaffected. A Parasitical relationships main difference from other symbiotical relationships is that only one organism benefits while the other is harmed.
I hope this helps :)
Explanation:
Firstly parasitism is the relationship between two species of plants and animals in which one benefits at the expence of the other, sometimes without killing the host organism while symbiotic involves the interaction between two different organisms living in close physical relationship
The difference between these two relationships are:
Parasitic relationship:
a. the organisms involved are called host and parasite.
b. the parasite benefits while the host is harmed.
c. some parasites make their hosts completely devoid from nutrients.
Symbiotic relationship:
a. the organisms involved are called symbionts
b. the organisms involved are mutually benefited
c. no special structures are used.

Hopefully this helps you a little bit
You work in a lab that studies brains and behavior. You and your labmate have both submitted rodent brains to a colleague to be sectioned. Your species is a squirrel that is known for storing large numbers of nuts each autumn in a variety of hidden locations. Your labmate's species is a mole with almost nonexistent eyes. How do you predict their brains will compare
The squirrel had a larger brain and is smarter. I say this because the squirrel has to be smart enough to gain a large amount of nuts, hide those nuts from others, and remember where those nuts are. On the other hand, the mole is less smart bc it is primarily underground. The mole's location underground helps to keep it safe from other predators so it doesn't have to worry too much about that. the mole also can't see which means that sight isn't of enough importance to keep.
