Energy of activation ________. a. is the energy required for molecules to react with each other b. requires the use of enzymes c. allows for feedback inhibition d. acts on the products of metabolic reactions
Answer:
a. is the energy required for molecules to react with each other
Explanation:
Activation energy may be defined as the extra energy required to start a reaction and the conversion of reactants into its products. It is the energy required to energize or activate molecules or atoms to undergo a transformation or a chemical reaction.
It is necessary for all types of chemical reaction to proceed. With the help of a catalyst the reaction rate increases as the energy of activation lower for the reaction to start.

List the process(es) you see in the model that take carbon dioxide OUT of the atmosphere.
Help:)
Answer:
D
Explanation:
The only process in the model that takes carbon dioxide out of the atmosphere is process D.
Process D is otherwise known as photosynthesis and it is peculiar only to green plants and blue-green algae.
During this process, the atmospheric carbon dioxide combines with another inorganic substance (water) in the presence of sunlight energy to produce carbohydrates (glucose). Oxygen is released as the by-product of the process and the equation is as below:
[tex]6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2[/tex]
5. The lion researchers in the film have studied 20% of the park and identified 41 lions. (Show your
work/justify your answer for each section.)
a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
Answer:
800 km²
Explanation:
If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.
4000 x .20 = 800
800 km² is your answer.
If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].
What do you mean by the researcher?A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.
According to the question,
The total area of Gorongosa park = Gorongosa park is 4,000 km²
The area which is already studied = 20%.
Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².
The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].
Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

How can the arrangement of atoms help explain how the white phosphorus and red phosphorus can both be pure phosphorus substances?
Answer:Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate.
Explanation:
Chemical element phosphorus has the atomic number 15 and the letter P in its symbol. Phosphorus, a multivalent nonmetal belonging to the nitrogen group, is generally always found in the form of inorganic phosphate, which is phosphorus in its maximally oxidized state.
What is phosphorus?The mineral phosphorus, which is also available as a supplement, is naturally present in many foods. It serves the body in a multitude of capacities. It is a crucial component of cell membranes, bone, and teeth. It maintains a healthy range of blood pH and aids in the activation of enzymes.
All tissues and cells must have phosphorus for growth, maintenance, and repair as well as for the creation of DNA and RNA, the genetic building blocks. The balance and usage of other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc, depend on phosphorus as well.
Thus, Chemical element phosphorus has the atomic number 15.

5. What type of microscope
would be best for studying cilia
Answer:
Scanning electron microscope and electron microscope.
Explanation:
Scanning electron microscope is a type of microscope which can produced the image of cilia. Electron microscope is a type of microscope would be the best for studying cilia because it has higher magnification power i. e. 10,000,000x, which able us to study different parts of cilia so we can say that electron microscope is the right choice for studying cilia.
What is the independent variable?
What is the dependent variable?
Answer:
the independent is the age of the tree and the dependent is the diameter
Explanation:
the diamter of the tree is based off of the age as we can see that it gets bigger the older the tree is
Answer: Independent variable: age of the tree (years), Dependent variable: tree diameter (mm)
The diameter of the tree is dependent on what age the tree is. As the tree gets older, the diameter increases. The dependent variable depends/relies on the value(s) of the independent variable.
1. What is the most important mutation that led to human life?
Answer:The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

c. It is the liquid portion of blood that includes the clotting factors.
d. It is the liquid portion of blood including the formed elements.
e. It contains the blood antigens that determine blood type.
Answer:
The correct answer is - option C.
Explanation:
Plasma is the liquid portion of the blood that carries water, salts, and enzymes in it and comprise almost 55% of the total blood volume. Other 45% of blood contains RBC, WBC, and platelets.
It is a yellow liquid that contains a clotting factor that helps in clotting blood if any injury occurs. Antigens are present on the RBCs not in the blood plasma that determines blood type.

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.
