The true statement about cholesterol is that; " It impacts membrane fluidity."

Cholesterol is one of the steroids in the body and serves as a constituent of many hormones. Cholesterol consists of a hydrophilic and a hydrophobic part hence it is able to interact both with aqueous and nonpolar environments.

Cholesterol impacts membrane fluidity in the sense that it regulates the direction of membrane fluidity. At high temperatures, cholesterol raises the membrane temperature whereas at high temperatures, it intercalates between phospholipids thereby preventing stiffening.

It is what makes each type of living creature different

Explanation:

DNA is basically our blueprint, how we were designed. It's almost impossible for someone's DNA to be exactly the same. Given the exclusion of twins, there is always going to be something different about creatures, even when it comes to doppelgangers!

Hope this helps!

DNA is important as it is what makes each type of living creature different. The correct option is D.

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

Nucleotides are chemical building units that make up DNA. A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components.

Nucleotides are joined together into chains, with the phosphate and sugar groups switching places, to create strands of DNA.

DNA is crucial for inheritance, protein coding, and supplying guidelines for life and its processes in all living organisms.

DNA controls a person's or an animal's growth, reproduction, and final demise. There are 46 chromosomes in total in each of a human cell's 23 pairs of chromosomes.

Thus, the correct option is D.

Correct alternative: a) The yellow color is dominant and the green color is recessive.

As observed in his experiment, Mendel identified that two factors determine the color of peas: a dominant for the yellow color and a recessive that expressed the green.

The dominant gene is the one that determines a characteristic, even when in simple doses in the genotypes. The recessive gene is only expressed when in double dose, because in the presence of a dominant, it becomes inactive.

Answer:

Some laws limit hunting, which may explain why there are so many. Since they are not hunted by humans, more of them have the ability to grow and reproduce. They also may not be hunted if they are in an area surrounded by houses. Hunting in these areas would be dangerous for other people.

The lack of natural predators could also be a reason. If there is nothing to eat them, they will grow and continue to reproduce. This can then lead to overpopulation.

Explanation:

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

The dew point if the dry bulb temperature is 20°C and the relative humidity is 17 % is 1.6°C.

Dew point is the temperature at which air becomes saturated with water vapor and begins to condense. The dew point is a significant meteorological parameter that represents the measure of atmospheric humidity. The dew point is a critical component in calculating relative humidity and heat index.

It also plays a crucial role in predicting the possibility of dew, frost, and fog. Given the dry bulb temperature of 20 C and the relative humidity of 17%, we can calculate the dew point as follows:First, find the saturation vapor pressure using the equation:Es = 6.11 × 10(7.5T / (237.7 + T))where T is the temperature in degrees Celsius.So, Es = 6.11 × 10(7.5 × 20 / (237.7 + 20)) = 23.48 mmHg.

Next, find the actual vapor pressure using the formula: E = RH/100 × E_s where RH is the relative humidity as a percentage. So, E = 17/100 × 23.48 = 3.99 mmHg. Finally, we can calculate the dew point using the formula: Td = (237.7 × log10(E/6.11)) / (7.5 - log10(E/6.11))Td = (237.7 × log10(3.99/6.11)) / (7.5 - log10(3.99/6.11)) = 1.6°C. Therefore, the dew point is 1.6°C.

Answer:

C) The rate applies to more individuals each year.

Explanation:

Suppose the initial population was 200 people and birth rate was 10% of that. So thats 0.10 * 200= 20 babies that year.

Next year the population is 200+ 20 = 220 people. Now if the birth rate is still 10% then you will have 0.10 * 220 = 22 babies that year.

Did you see that? The number of babies increased by 22-20= 2 extra babies each year.

Therefore, since rate applies to more individuals each year, you'll get increase in population

Answer and Explanation:

1. Hypothesis: The more sunflower seeds the students get, the better they will do on a quiz.

2. Dependent Variable: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.

3. Independent Variable: number of sunflower seeds. Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.

4. Constant Control Group: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment

5. Experimental Group: Groups 2 and 3, that received different amounts of seeds.

The data shows a significant decrease in grizzly bear deaths from 581 in the earlier period to 281 in the later period.

The information about grizzly bear deaths in Alberta from 1976 to 1988 and from 1988 to 2000 affects the prediction made in question 1 by providing additional data points and context.This decrease in grizzly bear deaths suggests a possible declining trend in the population. If the overall trend continues, it is reasonable to assume that the population has decreased further since 2000.

Taking this new information into account, the prediction made in question 1 should be revised. Instead of assuming a stable population or a slight increase, it would be more accurate to predict a decline in the grizzly bear population in Alberta. However, it is important to note that additional factors, such as conservation efforts or changes in habitat, should also be considered to gain a comprehensive understanding of the population dynamics.

Answer:

a. protects the environment.

Explanation:

Using water efficiently means using it wisely and not wasting it. When we use water more efficiently, we reduce the amount of water we consume, which helps to conserve water resources. This is important because water is a limited resource, and by using it efficiently, we can ensure enough water is available for future generations.

By using water more efficiently, we can also protect the environment. Water is essential for many ecosystems and habitats, and by conserving water, we can help maintain the balance of these ecosystems. Additionally, using water efficiently can reduce the need for energy-intensive water treatment and distribution processes, which can help reduce greenhouse gas emissions and mitigate climate change.

So, using water more efficiently helps protect the environment but also helps conserve water resources for the future.

Explanation:

The substance is mixed uniformly throughout, and each part of the substance contains the same ratio of materials in the same proportions, making it a homogeneous mixture. Option A is correct.

A mixture is made up of different types of substances or compounds. Depending on the composition of the mixture, it is classified as a homogeneous mixture or a heterogeneous mixture. The mixture in which all the components are equally distributed and can't separate is called a homogeneous mixture. Example: The air has different gases, but they can't be separated by hand.

In a heterogeneous mixture, the compounds or molecules do not mix together properly and can be differentiated, such as the small pebbles in the bag of rice. Aluminum, gold, copper, and other metals are examples of pure substances as they are made up of single particle.
