____________ polymerase is used to add new RNA nucleotides to make RNA.
Answers
RNA polymerase is used to add new RNA nucleotides to produce RNA.
RNA polymeraseIt is the enzyme responsible for copying the sequence of DNA into the sequence of RNA during the process of transcription.
The information encoded in DNA is used to produce RNA during the process of transcription.
The production of RNA takes place by the enzyme RNA polymerase, by using the antisense strand of the DNA as the template by supplementing the complementary RNA nucleotides to the 3 prime terminal of the developing strand.
The enzyme RNA polymerase combines with the DNA at a sequence known as the promoter at the time of the beginning of transcription.
Thus, the given blank can be filled with RNA.

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna
Answers
Answer:
C
Explanation:
The correct answer would be that more closely related species will have more similarities in DNA.
The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.
The correct option is, therefore, C.
Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.
The correct answer is:
Option C. More closely related species will have more similarities in DNA
The DNA stores the genetic information of the organisms and codes for the traits of the organism.
The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.
The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.
Therefore, option C is correct.

During photosynthesis, molecules inside chloroplasts in plant cells absorb energy from the Sun. Which statement best describes how photosynthesis follows the law of conservation of energy?
a. Light energy from the Sun is converted into kinetic energy in plant cells.
b. Chemical energy from the Sun is converted into light energy in plant cells.
c. Light energy from the Sun is converted into chemical energy in plant cells.
d. Chemical energy from the Sun is converted into thermal energy in plant cells.
Answers
During photosynthesis, the law of conservation of energy is followed when light energy from the sun is converted into chemical energy in plant cells. So the correct option is C.
What is photosynthesis?During the process of photosynthesis, the chlorophyll present in the chloroplasts of plant cells performs the function of trapping sunlight.
The sunlight trapped by the chloroplasts represents light energy. In plant cells, the light energy is converted to chemical energy. The chlorophyll molecule is photochemically excited and loses an electron. Thus it performs an oxidation reaction.
The chemical energy causes hydrolysis of water. The water molecule produces oxygen and hydrogen molecules. The oxygen molecule is released as a product of the photosynthetic reaction.
The hydrogen molecule is used for the reduction of carbon dioxide to form glucose which is a six-sugar molecule.
Therefore the correct option is C.

Answers
Answer:
The answer is B. base Have a great day!!!
The correct answers are:
1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.
The pH scale is the standard scale that specifies if an aqueous solution is acidic or alkaline/ basic. pH means the relative concentration of hydrogen ions, H+, and hydroxy OH- ions in the solution.
Lower pH values (0 - 7) exhibit more hydrogen ions which means the solution is acidic for instance Strawberry kool-aid add into the water strawberry kool-aid releases H+ ions in the solution.Hence strawberry kool-aid is an acid.
Higher values in the pH scale (7-14) are an indicator for the alkaline or base solution, Alka-seltzer changes pH from 5.4 to 8.3 which means the solution concentration of OH- ions increases and the solution becomes basic.Hence, the solution is basic and the Alka-seltzer gives hydroxy ions in the solution.
Given that baking soda is a strong base and hydrochloric acid is a strong acid, mixing both leads to salt and water as both have almost equal strengths of acid and base neutralization, therefore, the solution would be neutral or slightly acidicOn the basis of the given explanation, we can say that bleach is base as it has a pH value of 9.4 whereas coffee is acidic as pH value is 5.Thus, the correct answer is - 1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.
