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.

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.

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.

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.

1. Cushion plants - these are compact, low growing plants. These characteristics help them to survive in cold and windy conditions. They trap airborne dust and use it as a source of nutrients.

2. Arctic poppy - this has a hairy stem to retain heat. The flower can track the sun in the sky to maximize the amount of sunlight it receives so that it can increase photosynthesis.

3. Cotton grass - this grass has small seeds that can easily be dispersed by the wind to ensure its survival. It is low lying to protect it from cold winds and has thin leaves to reduce water loss by transpiration. Cotton grass grows and produces seeds quickly as soon as the temperature increases.

4. Lichen - this organism does not need soil to grow. It grows very slowly, can withstand very cold temperatures and survives beneath snow.

Many of a plant's hormones are secreted into intercellular fluid, while many of an animal's hormones are secreted into the blood.

Hormones are those substances which gives an organism  the ability to respond to both internal and external stimuli which are necessary for their growth and maintenance.

Plant hormones are also known as plant growth substances which are produced in small amounts within the plant body (intercellular fluid).

They control growth and growth movements by accelerating or inhibiting cell division, elongation and differentiation.

Examples of plant hormones include auxins (produced at the apices of shoots) and gibberellins.

The animal hormones are secreted by endocrine glands directly into the blood stream. There are then transported to where ever they are needed.

Examples of animal hormones include:
