Answer:
The temperature contrast from rural to urban areas is typically greatest during clear evenings with light winds. Rural areas cool off much faster at night than cities, as urban areas retain a lot of the heat stored in roads, buildings and other structures.

use the concept of natural selection to explain why organisms typically adapt over time
Answer:
natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species
Explanation:
Answer:
Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species. Eventually, the more favorable traits are incorporated into a species as the organisms that had those traits survive while the ones who do not die. This process takes time because it occurs through individuals with the favorable traits passing those traits on to future generations. Typically, the less favorable traits will not be eradicated in one generation.

Drug manufacturers must test their new products before they can be marketed. A pill containing a new drug was given to participants in Group A. A pill containing NO drug was given to the same number of participants in Group B. In this test, the drug given to the participants in Group A was the —
The drug given to the participants in Group A was the clinical trial drug.
After the manufacturing of a drug, the new drug needs to be evaluated before being pushed into the market for population use.
Researchers usually follow three main steps:
Preclinical drug trialsAnimal trials Human clinical trialsDuring the human clinical trials, drugs that have passed animal tests are used for human clinical trials.
This involves the use of two groups:
Group A: A pill containing a new drug known as the clinical trial drug will be given to participantsGroup B: A pill containing NO drug known as placebo will be given to the same number of participants.The results obtained from both grouped would be evaluated. This will give the manufacturer a clear view concerning the new drug, if it is safe and effective in people.

Pablo and Johanna must complete a yearlong study for their biology course. After some discussion, they decide to compare dog diets. To test their hypothesis that the local veterinarian's special dog food mix will enhance growth and development, each student adopts a puppy from the local pound. Pablo plans to feed his goldendoodle the special diet, while Johanna plans to use generic dry kibble from the supermarket for her bulldog. Pablo and Johanna have too many ________.
Pablo and Johanna have too many independent variables.
In order to conduct an experiment, 3 kinds of variables are used. These are:
Dependent variable Independent variable Control variableA dependent variable is a variable that the experiment seeks to observe and measure, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable. Finally, the control variable is the variable that remains the same throughout the experiment in order to limit the influence they will have on the outcome. If the value we wish to measure changes, the presence of control variables helps to narrow down and correctly credit the cause of this change, leading to a valid experiment.
In the situation given, Pablo and Johanna have too many independent variables. The dependent variables that Pablo and Johanna wish to measure are dog growth and development. The independent variable is the one they change in order to see what effect it will have on the dependent variable, in this case, the dog food. However, the experiment would not be valid because the breed of dog should be a control variable to ensure correct data, given that different breeds of dogs grow and develop at varying rates. This variable is instead an independent variable in this given experiment, given that it changes between the two groups and will affect the outcome.

Explanation:

it was correct.
photosynthesis and cellular respiration work together to create the life cycle. without Cellular respiration we would die and without photosynthesis we would die. They are equally important without one the other could not function
have a great day
:)
Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.
What is the relation between cellular respiration and photosynthesis?Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.
The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.
Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.

Which type of biomolecules are made up of fatty acids?
a. carbohydrates
b. proteins
c. lipids
d. nucleic acids
Answer:
c. lipidsExplanation:
As,
A lipid is a phospholipid, a major structural component of all cell membranes. It is composed of a glycerol molecule, two fatty acids
The type of biomolecule that is made up of fatty acids is Lipids and thus, option C is the correct answer.
Nucleic acids, Lipids, Proteins, and Carbohydrates, are some of the significant biomolecules. The characteristics of lipids are listed as follows:
The organic molecule that is specifically related to fatty acids and can be able to dissolve only in organic solvents and not in water are called lipids. The lipid molecule is composed of 1 molecule of glycerol and 3 molecules of fatty acids that are linked to one another. Oils, waxes, fats are some examples of lipid molecules.Thus, we can conclude that lipids are the type of biomolecules which is made up of fatty acids.
