Answer:
Generally the primary organic molecules in cells which support the metabolic and biochemical process of the cells are bio molecules Theses are Carbohydrate
Protein
Lipids
and Nucleic acids of DNA and RNA. They can also be the minute hormones and metabolites present in the cells.
Generally, CHO provide structural supports to the cells,and acts as sources of energy.
Protein forms most enzymes for biochemical reactions,and aids movements, through muscle contractions. Besides,muscles are made of protein.Therefore protein forms the structural basis of the muscles.This aids movement and locomotion for support.
Lipids are the richest source of energy for the cell,and provides support the cells membrane.
The nucleic acids,are primary concerned with the transfer of inheritable characteristic from mother cells to the daughters during reproduction.While the DNA is the genetic information been transferred,the RNA is the vehicle for transmission of the genetic information as protein from the parents' nucleus to the offspring.

The mutation that causes SCD causes what kind of change in the structure of hemoglobin?
Answer:
A group of blood disorders generally passed on from the parents to the offspring is known as SCD or sickle cell disease. Of the disease, the most common is the SCA or sickle cell anemia. In the disease, the red blood cells comprise an abnormal form of the oxygen-carrying protein hemoglobin.
Generally, humans comprise hemoglobin A, A2, and F types. Of the three types, the hemoglobin F dominates till the age of 6 weeks, after which hemoglobin A dominates till the end of life. However, in the persons diagnosed with SCA, at least one of the beta-globin subunits in hemoglobin A gets substituted by a different form known as hemoglobin S. In the disease, a single nucleotide mutation in the beta-globin gene takes place, in this at 6th position, the glutamic acid gets replaced by Valine.
a beaker cannot be used for measuring the volume of a liquid because
Answer:
Beakers should not be used for measuring a liquid's volume because beakers can be inaccurate. For example, they are typically accurate within 5 percent. Beakers should only be used for approximating volume.
A better choice for accurate volume would be a graduated cylinder, since they are accurate within 1 percent. The best options are pipets, burets and volumetric flasks. All three are accurate within less than 0.2%.
Essentially, beakers are not precise, and therefore should not be used for measuring the volume of a liquid.

What type of weak bond occurs when atoms and molecules are temporarily attracted to each other by virtue of their proximity and
charge
The weak bonds that occur when atoms and molecules are temporarily attracted to each other by virtue of their proximity and charge are Vander Waal forces.
What are Vander Waal forces?Van der Waals forces are weak forces that keep electrically neutral molecules together. At some point, these molecules have an induced dipole, which means they have a partially positive and partially negative charge for a brief period of time, leading them to attract one other.
They are forces of Van de Waals: The movement of electrons causes dispersion forces between non-polar molecules (union between atoms of the same element or between atoms with very little electronegativity difference).
Therefore, Vander Waal forces are the weak bonds formed when atoms and molecules are temporarily attracted to each other due to their proximity and charge.

which of the following best describes the role of an enzyme in living organisms
Answer:
They cause DNA to replicate. They denature each other. They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
The statement that best describes the role of an enzyme in living organisms is enzymes always break down substrates into monomers during a reaction. The correct option is c.
What are enzymes?
Enzymes are proteins that increase the rate of the reaction. In the human body, enzymes are used to break down food molecules. Enzyme inhibitors are biological or chemical substances that bind to an enzyme's active site and prevent the enzyme from performing its activity.
The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. This in turn dictates the enzyme's three-dimensional structure, including the active site's shape.
Therefore, the correct option is c, Enzymes always break down substrates into monomers during a reaction.

a) kidneys eliminate bicarbonate ions.
B) kidneys retain bicarbonate ions.
c) kidneys retain hydrogen ions.
d) kidneys eliminate carbon dioxide.
Answer:
B) kidneys retain bicarbonate ions
Explanation:
Respiratory acidosis involves the inability of the lungs to remove the Carbon dioxide in the body which result in the blood being acidic.
Jane was said to suffer a chest injury that resulted in impaired breathing and respiratory acidosis. Her body will compensate for this imbalance through the kidneys having the ability to retain bicarbonate ions. This helps to reduce the acidity as the ions are alkaline in nature.
Which of the following relies on amolecule binding to the repressor to prevent the repressor from binding to the operator?
a. repression
b. gene expression
c. an operon
d. induction
Answer:
d. induction
Explanation:
A repressor is a protein capable of inhibiting target gene expression by binding to both operator sites and gene silencers. A DNA-binding repressor inhibits the interaction between the RNA polymerase and the DNA promoter sequence, thereby suppressing transcription into RNA. Moreover, the RNA-binding repressor is a protein that binds to the messenger RNA (mRNA) molecule in order to prevent its translation into protein. An inducer can start transcription by interacting with the repressor, thereby separating it from the DNA operator sequence.
The number of possible chromosomal orientations during metaphase I is equal to the number of chromosome pairs raised to the 2nd power.
A. True
B. False
Answer:
A
Explanation:
The statement is entirely true.
During metaphase 1 of meiosis, each tetrad - a chromosome consisting of 4 chromatids - formed in prophase has 2 possible orientations. Hence, the total number of possible chromosomal orientations would be 2 raised to the power of the number of chromosome pairs present in the cell.
For example, humans have 23 pairs of chromosomes in each of their cells, hence, the total number of possible chromosomal orientations would be [tex]2^{23}[/tex] which is equal to 8,388,608 possible orientations.

HOPE IT HELP....You decide to halve the time you spend in the shower each day and to turn off the water while you’re brushing your teeth and washing your face at the sink. Evaluate the effect that these actions might have onto different aspects of the water cycle if every person in your neighborhood also performed them.
Answer:
Decreasing the consumption of water helps to maintain the fresh waters of our planet, the less we consume the less quickly they will end.
If we abuse fresh water, one day the planet will end and the salt water from the seas will have to be filtered, which is much more expensive and more polluting.
Explanation:
In addition, we must bear in mind that the less we use the water, the less we will contaminate it with chemicals such as shampoos, rinse creams, soap, therefore less water will end up in the non-recyclable water cycle.
All the water we use will end up being polluted and will not enter the natural cycle of water from river rainfall, irrigation and evaporation in the skies.

Given the following DNA template, what is the appropriate mRNA strand
3' TACTTCAAACCGATT 5'
Answer:
5' AUGAAGUUUGGCUAA 3'
Explanation:
The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.
The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.
For the DNA sequence;
3' TACTTCAAACCGATT 5'
The mRNA sequence will be synthesized;
5' AUGAAGUUUGGCUAA 3'
