Give two incidents of osmosis process

Answers

Answer:

Raisin In Water. If you put a raisin into pure water, it swells up over time. This happens because raisin contains a higher concentration of sugar and other solutes than water, so water moves into the raisin cells by osmosis. Since the solvent (pure water) enters into the raisin cell, this is an example of endosmosis.

b) substrates work on enzymes, allowing them be be denatured.

c) the shape and size of the enzymes does not matter.

d) enzymes are not specific and work on a variety of substrates.

Answers

Answer:

the answer is option b hope you understand

The lock and key mechanism of enzyme and substrate means that if they don't fit, it is the wrong substrate or the enzyme is denatured.

WHAT IS AN ENZYME?

An enzyme is a protein substance that regulates biochemical activities in living cells by acting as a catalyst.

Enzymes act on substrates but they do not get changed during the process. This means that enzymes can be used over and over again.

Enzymes are substrate-specific i.e. they act on specific substrates. The lock and key model explains the mechanism of action of enzymes. Enzymes attach to substrate at their active sites and act on them to form products.

The lock and key model explains that if enzyme and substrate don't fit, it is either the wrong substrate or the enzyme is denatured.

Consider an experiment in which subjects are given a pill to test its effectiveness in reducing the duration of a cold. Which of the following is the best way to treat the control group.
A. Give the control group two pills instead of one.
B. Do nothing with the control group.
C. Give the control group a pill that looks like the test pill but does nothing

Answers

Answer:

c.

Explanation:

(comment if you need an explenation and I'll give it)

Give the control group a pill that looks like the test pill but does nothing is the best way to treat the control group. Option C is correct.

The best way to treat the control group in this experiment is option C: give the control group a placebo pill that looks like the test pill but does not contain any active ingredients. Here's why:

Ensuring Validity: A control group is used to establish a baseline for comparison. By giving the control group a placebo pill that looks identical to the test pill, researchers ensure that both groups experience the same psychological and physical conditions except for the presence of the active ingredient. This helps eliminate potential bias and confounding variables that could affect the results.

Blinding: Giving the control group a placebo maintains blinding, where participants do not know whether they are receiving the active treatment or the placebo. This prevents participants' expectations or beliefs from influencing the outcomes, enhancing the experiment's validity.

Placebo Effect: The placebo pill accounts for the placebo effect, a psychological phenomenon where participants experience improvements in their condition due to their belief in the treatment's effectiveness. By giving the control group a placebo, researchers can assess whether the test pill's effects are genuinely due to the active ingredient or influenced by participants' perceptions.

Ethical Considerations: It's important to provide some form of treatment to the control group to ensure they are not harmed or misled. Giving them a placebo pill with no therapeutic effect is an ethical way to include them in the study while minimizing potential risks.

Overall, using a placebo that mimics the appearance of the test pill ensures a controlled and rigorous experiment, where the effects of the active ingredient can be accurately evaluated. This approach maintains scientific integrity, valid comparisons, and ethical considerations.

What process makes children different than their parents?

Answers

Answer:

So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called 'genetics'.

Explanation:

Even where children's genes look identical to their parents, their bodies and minds could well differ, influenced by many other factors, including the portions of the parents' DNA that don't code for genes, their environment, and their behavior.

Explain the similarities and differences that exist between these species and humans.

Is the fossil record complete for humans? Explain your answer.

Answers

Answer:

A  Gigantopithecus, Paranthropus, Adripcines, and an Orrorin.

The similarities they have with us are the face features, personality traits, and DNA. The differences is that they have way more body hair, communication, and mental abilities.

Explanation:

Hope this helps you :)

Chimpanzees and bonobos are the two species that closely related to humans.

The fossil record shows that the DNA of human and ape are closely related to each other which indicates that about 6 million years ago humans shared a common ancestor with the Great apes such as chimpanzees and bonobos.

Human DNA is similar to chimpanzee DNA about 98.6%. Both are also similar in physical makeup and intelligence. The main difference between human and chimpanzee is that the chimpanzee walks on four limbs and they can't swim whereas humans walk on two limbs and can swim so we can conclude that the chimpanzee and bonobos resembles to human to a great extent.
