In nature, mutation rates aren't usually high enough to maintain alleles that are not favored in a population by natural selection.
While in the wild, many populations are led by natural selection. This means that favorable traits are passed down through generations, while unfavorable traits are not. Traits that are best suited for the environment of the organism will prevail to help the chance of survival.
Mutation rates usually aren't high enough to create traits that are unfavorable to an organism. While mutations are still possible, it is still unlikely. The traits that are chosen by natural selection are most likely to be passed onto organisms and their offspring.

All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.

(C) two
(D) one
Defined as variation of life on Earth, ____________ is the number and relative abundance of different species.
Answer: Diversity
Explanation: The earth is composed of different species of organisms spread across various parts and regions of the earth. The idea of having varying classes of species scattered on the earth is called diversity culled from the word diverse, which is used to describe a property of Variation in component. Hence, diversity explains the variation in the number and size of different species, culture and languages (biodiversity) and other components of the human existence. Additionally, the concept of diversity helps us realize the need to respect and embrace our differences in other to foster progressive relationship.
Variety is important within populations because
Trevor wanted to find out what fertilizer worked best for growing marigolds. He put Miracle Grow on one, Scotts fertilizer on another, and no fertilizer on the third marigold. What is the control?
a. Marigold with no fertilizer
b. Type of fertilizer
c. Plant growth
d. Amount of water
Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.

Did the enzymes from Claire's small intestine break down the
protein at a low, normal or high rate?
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.
Small intestine of Claire break down the protein at a low rate.
The enzymes from Claire's small intestine break down the protein at a low rate because the proteases is present in a very low amount in the small intestine. The proteases enzyme is responsible for the break down of proteins.
If proteases is present in large amount then the protein present in food is broken down at a faster rate while on the other hand, if the proteases is present in small amount then more time is needed to digest the protein so that's why Claire's small intestine break down the protein at a low rate.

What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodiversity? How could a disturbance affect the biodiversity of the coral reef?
Answer:
The two abiotic conditions in the coral reef that contribute to the high biodiversity are:
TemperatureSunlightWhilst the abiotic factors are
Plant and BacteriaExplanation:
The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.
The above factors contribute immensely to the stability and operability of the great reef.
The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.
It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.
The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.
It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

What are control variables?
Answer:
scientific experimentation is an experimental element which is constant and unchanged throughout the course of the investigation
Explanation:
throughout the course of the investigation.
The control variables themselves are not of primary interest to the experimenter.

Explanation:
Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be described as the smallest living unit?A.) OrganelleB.) DNAC.) ProteinD.) Cell
Answer:
The correct answer is:
Cell (D.)
Explanation:
The cell is the basic structural, functional and biological unit of a living organism that is the smallest unit of life. It is said to be the building block of life. Being the smallest unit of life, a cell is a collection of organelles and biomolecules that can function independently and still possess the qualities of life. These structures are enclosed in a cytoplasm, within a membrane, and these biomolecules include Nucleic acids (DNA, RNA), proteins etc.
