If the first nucleotide after the promoter on the bottom DNA strand is changed from C to T, what would the resulting nucleotide be on the mRNA
When the DNA's C is changed to T, the corresponding nucleotide on the mRNA strand will be A (adenine) to maintain the complementary base pairing.
Nucleotides encode genetic information in DNA. Due to complementary base pairing laws, DNA sequence alterations impact mRNA transcript nucleotides. If the first nucleotide following the promoter on the bottom DNA strand changes from C (cytosine) to T (thymine), the matching mRNA strand nucleotide becomes A.
Because C pairs with G (guanine) in DNA and RNA. T in DNA matches A in RNA owing to complementary pairing. The DNA sequence will influence the mRNA sequence during transcription, which may impact the protein synthesised during translation.

The graph above shows the initial rate of an enzyme-catalyzed reaction at
different substrate concentrations in the presence of a constant
concentration of the enzyme.
Connect the primary structure of the enzyme to its overall shape.
The overall shape of an enzyme changes after the attachment with the substrate.
Enzymes are proteins composed of amino acids that linked together in one or more polypeptide chains. This sequence of amino acids in the form of polypeptide chain is known as the primary structure of an enzyme.
The tertiary structure is the enzyme's overall three dimensional structure, which occurs due to interactions between the R groups of the amino acids that make up the protein and the active sites of the substrate with which the enzyme can attach so we can conclude that the overall shape of an enzyme changes after the attachment with the substrate.

The primary structure of enzymes determinies their functions and their secondary and tertiary structures. R groups remain in the center of the molecule and stabilize the structure.
--------------------------
To answer this question, we need to remember that enzymes are proteins, and hence, they share many properties. From now on, we will refer to the enzyme as proteins or molecules.
AMINO ACIDSAmino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH2), and one R group.
The composition of the R group is what makes them different from each other.
PROTEINS -enzymes-Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.
The peptidic bond is the union of two amino acids by their carboxyl and amine groups.
The R group of each amino acid is involved in stabilizing the molecule through their interactions.
The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.
Protein functions also depend on the aminoacids sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
PROTEIN STRUCTURE
The primary structure refers to the sequence in which the amino acids are arranged in the chain.
The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds.
The three-dimensional structure makes them even more stable in the environment and capable of properly accomplishing their biological role.
When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.
The hydrophilic R-groups remain in the center of the molecule, facing the protein interior, and avoiding interaction with water.

The sympathetic nervous system's stimulation response is balanced by the parasympathetic nervous system's ________ response.
Answer: akinesia
Explanation:because it’s a nervous system
The sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.
The autonomic nervous system (ANS) is divided into the parasympathetic nervous system and the sympathetic nervous system.The parasympathetic nervous system is responsible for normal body functioning and homeostasis, whereas the sympathetic nervous system deals with the fight, flight, or freeze responses.The parasympathetic system promotes rest-and-digest activities when the body is at rest.In conclusion, the sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.

Is the cholesterol molecule mostly polar or mostly nonpolar?
Answer:
Most of the cholesterol molecule in non-polar and therefore associations with the non-polar fatty acid tails of the phospholipids. However, the hydroxyl group (-OH) on cholesterol carries a negative charge and therefore associates with the polar environment of water either inside the cell or outside.
Explanation:

How do lenses correct vision?
A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.
Answer: D
Explanation:
Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.
Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.
What is the function of lenses?Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.
Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.

No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection.

The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
