What effect would the enzyme have on the time to make 1 mg of product?
Answer:
The time to make the product will be reduced.
Explanation:
Enzymes are substances that acts as biological catalysts and speed up the rate at which a chemical reaction occurs by lowering the activation energy of the reaction. The activation energy is the energy required for the chemical reaction to occur.
Hence, when making a product of size 1mg, the presence of an ENZYME will reduce the amount of time required for the products to form i.e. the reaction will be sped up.
The effect the enzyme would have on the time to make 1 mg of product is reduction in the time to make the product.
First, let us define what enzymes are.
Enzymes are proteins that act as biological catalysts; and catalysts accelerate chemical reactions.
Simply put, enzymes make reactions go faster or we say enzymes speed up a chemical reaction.
Enzymes make reactions go faster by lowering the reaction's activation energy.
Activation energy is the minimum amount of energy that must be provided for compounds to result in a chemical reaction
Hence, since enzymes make reactions go faster, then the effect the enzyme would have on the time to make 1 mg of product is, reduction in the time to make the product.

HELP.......Which best describes a way photosynthesis provides resources to animals?
Answer: I think B.
Explanation: A and D make no sense, and I just learned about photosynthesis and animals or plants need for water cannot decrease.
Photosynthesis increase plant growth, providing places for many animals to live.
What is photosynthesis?Photosynthesis provides resources to animals indirectly, by serving as the source of energy and organic matter for plants. During photosynthesis, plants convert light energy into chemical energy stored in organic molecules like sugars.
These sugars and other organic compounds produced by photosynthesis are then used by plants as a source of energy and building materials. When animals consume plants or other organisms that have consumed plants, they obtain the energy and organic matter stored in these molecules, allowing them to use the resources generated by photosynthesis for their own growth and survival. Therefore, photosynthesis plays a critical role in the food chain and supports the entire ecosystem, including the survival of animals.

What proteins are crucial for creating and maintaining DNA replication forks? Choose the best explanation.
Answer:
Explanation:
The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule
The protein that is crucial for creating and maintaining DNA replication forks is DNA helicase, which is in option A. Helicases are enzymes that unwind and separate the DNA double helix, creating the replication fork.
DNA helicase use energy from ATP hydrolysis to break the hydrogen bonds between the DNA strands, allowing for the replication process to proceed. DNA polymerases are a group of enzymes responsible for synthesizing new DNA strands during replication. They add nucleotides to the growing DNA chain, following the template provided by the parental DNA strands. DNA polymerases catalyze the formation of phosphodiester bonds between the nucleotides, resulting in the elongation of the new DNA strands. SSBs bind to single-stranded DNA exposed at the replication fork and stabilize the unwound DNA strands. They prevent the separated DNA strands from re-annealing or forming secondary structures, ensuring that the DNA template remains accessible for replication.

Answer: A company decides to switch to solar energy to produce electricity for their building. Why might they have made this decision? Select the two correct answers.
The two correct answers would be:
Solar energy systems have minimal environmental effects
Solar energy does not produce air pollutants or carbon dioxide
Explanation:
If you look up how to get solar energy it helps you easier understand why they have minimal environmental effects and how it does not produce air pollutants or carbon dioxide.
A business decides to transition to using solar energy to power their structure. Systems that use solar energy have negligible environmental impacts. Carbon dioxide or other air pollutants are not produced by solar energy.
What is Solar energy?The amount of sunlight that reaches the surface of the earth in an hour and a half is sufficient to meet all of the world's energy needs for a complete year.
Solar energy systems either use photovoltaic (PV) panels or mirrors to focus solar radiation to convert sunlight into electrical energy.
The basic principles of solar radiation, photovoltaic and concentrating solar-thermal power technologies, the integration of electrical grid systems, and the non-hardware components (soft costs) of solar energy are covered in the resources and information provided below.
Therefore, A business decides to transition to using solar energy to power their structure. Systems that use solar energy have negligible environmental impacts. Carbon dioxide or other air pollutants are not produced by solar energy.

In chickens, feather color is codominant. If a black chicken BB is mated with one that is black and white (BW) what are the chances of having a chicken that is black and white?
Answer:
1/2
Explanation:
BWxBB= BB BB BW BW BW is black and white and BB is all black
The chances of having a chicken that is black and white from a mating between a black (BB) chicken with one black and white (BW) chicken will be 50 percent (50%).
In genetics, codominance occurs when two alleles of the same gene are both expressed in heterozygous individuals.
In consequence, in codominance, the phenotype of heterozygous individuals results in a mixture of both codominat alleles.
In this case, the first parent is homo-zygous for the allele 'black' (genotype BB), thereby this individual only can produce gametes with the B allele (100%).
Moreover, the second parent is heterozygous for the alleles 'black' and 'white' (genotype BW), thereby this individual can produce two types of gametes in equal proportion (50%): gametes having 'B' allele and gametes having the 'W' allele.
In consequence, in this case, it is expected to obtain individuals expressing the homo-zygous 'black' phenotype (genotype BB) and individuals expressing the heterozygous 'black and white' phenotype (genotype BW) in equal proportion (i.e., 50% genotype BB, 50% genotype BW) >>
Punnet square (F1):
W B
B 1/2 BW 1/2 BB
In conclusion, the chances of having a chicken that is black and white from a mating between a black (BB) chicken with one black and white (BW) chicken will be 50 percent (50%).
