Hope this helps
The molecule that is solid at room temperature is the saturated fats.
Fatty acids or lipids are organic compounds that are poorly soluble in water but miscible in organic solvents.
The two major types of fatty acids are
Saturated fatty acid and Unsaturated fatty acid.Saturated fatty acids contains no double bond in their carbon chains. This is the main reason why they are solids at room temperature.
The sources of saturated fatty acids include:

What stages of the water cycle where water moves downward from the force of gravity
Answer:
Precipitation, Surface Runoff and Infiltration process
Explanation:
There different stages of the water cycle where the water comes back on earth due to the gravitational force are as follows-
Rainfall/Precipitation- The water vapour in the cloud undergoes the process of condensation, it leads to the occurrence of rainfall, where the water comes freely over the ground surface from a certain height.
Surface Runoff- These refer to the flow of water rapidly along a steep slope, under the influence of gravity that eventually adds to the streams, lakes and rivers.
Infiltration process- This is the process where the water from the earth's surface percolates through the rocks and flows downward and eventually mixes with the groundwater.

A. Producers create energy for the other trophic levels to use.
B. Producers consume other trophic levels to pass their energy up the food chain.
C. Producers capture the energy from the sun for all other trophic levels to use.
D. Producers recycle nutrients back into the food chain
Answer:
D
Explanation:
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water

Which revision changes the dependent clause into an independent clause?
After the conversation with her publisher, because she decided to write an autobiography.
Since the conversation with her publisher, when she decided to write an autobiography.
After having the conversation with her publisher, when she decided to write an autobiography.
After the conversation with her publisher, she decided to write an autobiography.
Answer:
The correct answer is - After the conversation with her publisher, she decided to write an autobiography.
Explanation:
The revision that alters the dependent clause (incomplete thought) into an independent clause (a complete thought) is the following one:
"After the conversation with her publisher, she decided to write an autobiography."
The reason behind this is that an independent clause is a clause that expresses a complete thought and no need for other clauses to be associated.
The other options (a and b) are grammatically incorrect when presented as independent clauses, whereas D is completely okay.
Answer:
D - After the conversation with her publisher, she decided to write an autobiography.

Human blood type is an example of which two types of genetics?
A. Multiple alleles and Polygeic inheritance.
B. Incomplete dominance and Polygenic inheritance.
C. Codominance and Multiple alleles.
D. Codominance and Incomplete dominance.
Answer:
The correct answer is option C. "Codominance and Multiple alleles".
Explanation:
Human blood type is a concept developed to understand how blood transfusion can be successfully performed, and is based on the presence and absence of antibodies and antigens in the surface of the red blood cells. Human blood type is an example of genetics codominance and multiple alleles. It is an example of codominance because some people express both allele A and allele B in what is known as blood type AB; and it is an example of multiple alleles since there are three alleles: type A, type B and type O.
The distribution of blood on basis of antibodies and antigenic heritage is called blood type. The main groups of blood types are A, B, AB, and O.
The correct answer is:
Option C. Co-dominance and Multiple alleles.
This can be explained by:
Among the presence of two alleles, neither of them can suppress the presence of another allele that is, both of the alleles will be expressed simultaneously this is called Co-dominance.In human blood type when the allele for A and B is present then, they will be expressed concurrently and the blood group will be of AB type.The ABO blood kind in humans is an example of multiple alleles. Human genes for blood type exist as [tex]\text I^{\text{A}}[/tex] , [tex]\text I^{\text{B}}[/tex] and [tex]\text I^{\text{O}[/tex]. Only two of the three genes is expressed in the human cells
Therefore, Human blood type is an example of Co-dominance and Multiple alleles.

What is the purpose of having ampicillin in the plate?
Answer:
Ampicillin in a plate do as to help in maintaining ampicillin resistance plasmid in the growing medium
Explanation:
Ampicillin is an antibiotics that help to kill E.coli bacteria .
While growing bacteria in a plate or growing medium, it is important to add ampicillin to the plate so to maintain ampicillin resistance plasmid.
The absence of ampilicin, the bacteria will lose their resistance after they might have gone through some cell divisions and any bacteria that doesn't have resistance plasmid will be more vigorous than those that have and will outcompete them

4. Using a complete sentence, state what would most likely happen to the production of oxygen by duckweed plants if the intensity and duration of exposure to light were increased.
Answer:
See the answer below
Explanation:
If the intensity and duration of exposure to light are increased for a duckweed plant, the rate of photosynthesis would increase and this would lead to an increase in the amount of oxygen produced.
From the equation of photosynthesis:
[tex]6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2[/tex]
the more the rate of photosynthesis, the more the amount of oxygen produced. Also, an increase in the intensity of light generally increases the rate of photosynthesis (and oxygen production) provided that other reactants can catch up. The rate of photosynthesis would become limited by the reactant that is available in the lowest quantity.

c. being immune to scorpion stings
d. razor sharp teeth
Answer:
c.
Explanation:
over time you adapt to be immune to scorpio stings
Being immune to scorpio stings is an example of a biochemical adaptation. Thus c is correct option.
What is biological adaptation?
A biological adaptation is defined as physical change in an organism that allow the organism to survive in their environment. Adaptation can be seen in three form i.e structural behavioral and physiological.
Adoption has been described from the time ancient Greek philosophers known as Aristotle.
In the process of adaptation the source of all genetic variation there would be no genetic changes occur.
When there is increase in mutation genetic change occurs in a population.
Adaptation is generally relates to biological fitness which is responsible for rate of evolution due to change in allele frequencies.
Therefore, being immune to scorpio stings is an example of a biochemical adaptation. Thus, c is correct option.

what is the purpose of having distilled water as one of your test substances?
Distilled water does not have any cellular or mineral contamination. It is used in experiments for accurate results.
What is distilled water?It is a type of water that is completely purified of any kind of impurities. It does not have any minerals, salts, or organic materials.
Distilled water is the liquefied stream. When the water is boiling, it turns into a stream. This is collected and the steam is turned back to liquid. The steam doesn't carry an impurity of water with it and so distilled water formed from steam is also devoid of any impurities.
Distilled water is safe to drink but it will not taste anything like regular water. The water in our homes is supplied with minerals. These minerals are required for various processes in our body. Distilled water doesn't have any such minerals. Hence it's safe to drink but it's not beneficial.
Therefore, distilled water is used in experiments as there is no chance of contamination or reaction with this. This is used as a control against the test substances.
