1. **In the procedure shown below, a calcium chloride solution is mixed with a sodium sulfate solution to create the products shown. Which of the following is illustrated by this activity?
a. The law of conservation of mass
b. The theory of thermal equilibrium
C. The law of conservation of energy
d. Newton's 2nd Law
The reaction follows the law of conservation of mass since the mass remains same before and after the reaction. Therefore, option (A) is correct.
What is the law of conservation of mass?According to the principle known as the rule of conservation of mass, during a chemical reaction, mass can neither be created nor destroyed. When coal is burned, for instance, the atom of carbon that it contains transforms into carbon dioxide. The mass of the carbon atom remains constant even as it transforms from a solid structure to a gaseous state.
The study of chemical reactions, as well as their generation, places a significant emphasis on the principle of mass conservation. Scientists are able to make accurate forecasts regarding the amounts of products that will be produced from a certain reaction if they are aware of both the amounts of reactants and their identities.
Thus, in the above reaction the mass is conserved and option (A) is correct.

Answer:
This is because there may be one large producer or a small number of very large producers. For example, adult oak trees are extremely large and a single one may be home to hundreds of organisms. Thus, the number of organisms in the lower level of the pyramid of numbers will be less.

Which of the following molecules are needed for photosynthesis?
Answer:
Carbon dioxide and oxygen is needed for photosynthesis, and water if you have the choice.
Explanation:
The molecules needed for photosynthesis are carbon dioxide and water.
What is photosynthesis?Photosynthesis is a process performed by green plants where they are able to synthesize their own food material from inorganic material using sunlight.
Photo - light and synthesis - to make. So the word photosynthesis means to "make something using light".
In green plants, the mesophyll cells of the leaves contain a green pigment called chlorophyll. It is present in the grana of their chloroplast. The chloroplast is thus the site for photosynthesis.
The inorganic matter required for photosynthesis is obtained from the environment. The carbon dioxide is obtained from the atmosphere by the stomata and water is absorbed by the roots.
The chlorophyll traps the sunlight which provides the energy for the hydrolysis of water and the formation of glucose and oxygen as a byproduct.
Therefore, the molecules required for photosynthesis are carbon dioxide and water.

In tomatoes, the following hypothetical pathway gives rise to different fruit colors. Y gene R gene Precursor substrate Intermediate substrate Product and lacks color and fruit is and fruit is yellow fruit is red green from chlorophyll Mutations in the genes for both of the enzymes produce lack-of-function, recessive alleles. What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual
Answer:
Explanation:
From the information given:
The analysis of the hypothetical pathway gives:
Y gene R gene
Green fruit → Yellow fruit → Red fruit.
If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:
RrYy × RrYy
The progenitors to undergo the segregation are as follows:
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
(red) (red) (red) (red)
Ry RRYy RRyy RrYy Rryy
(red) (green) (red) (green)
rY RrYY RrYy rrYY rrYy
(red) (red) (yellow) (yellow)
ry RrYy Rryy rrYy rryy
(red) (green) (yellow) (green)
Thus; the expected phenotypic ratio is:
= 9(red) : 3(yellow) : 4(green)
The expected phenotypic ratio is:
= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)
Reverse transcriptase is a useful enzyme to have when?
Answer:
Reverse Transcriptase (RT) is essential for HIV replication because the viral RNA genome on its own is highly susceptible to degradation by intracellular RNases. RT rapidly makes a much more nuclease-resistant double-stranded DNA copy of the RNA template that later integrates to form the proviral DNA.
This molecule is used by retroviruses to create DNA by using mRNA as a template. We know that normally transcription is the synthesis of mRNA from DNA. This can be useful in bioengeneering when using a virus as a vector to alter the genetic material of the host.

Which of the following statements about the structure of DNA is true?
A) It contains adenine, uracil, guanine, cytosine, and phosphorus.
B) It is composed of phosphates, nitrogenous bases, and ribose sugars.
C) It is composed of a single strand that consists of deoxyribose and phosphate.
D) It contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.
Answer:
D
Explanation:
dna does not contain uracil. (uracil is in RNA)
dna does not have ribose sugars (ribose sugars are in RNA)
dna is not a single strand.
dna contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.
DNA is a double stranded molecule. It has two strands of deoxy ribose sugar and the phosphorus groups where the H and OH bonding is present as well. It contains A,T,C and G. 4th option is correct.
What is the the full form of DNA ?DNA stands for deoxyribonucleic acid. It is made up of nucleic acid comprised with the sugar at which O is removed at the 2nd position.
DNA is double stranded in nature. The strand one of between the two strands where the first is called as template strand and the other one is called as coding strand. DNA copies DNA and the process is called as replication. DNA replication unit must have one ori that is origin of replication, promoter that is mostly attached at the 5' end of the strand.
The unit continues to add on bases in order to make the strand until the synthesis is complete. The nitrogenous bases of DNA are A,T,C and G where A stands for adenine, T for thymine, C for cytosine and G for guanine.
Therefore only option D is correct.
