how does the operator region of dna work to regulate gene expression?.
Answer:The promoter is found in the DNA of the operon, upstream of (before) the genes. ... Some regulatory proteins are repressors that bind to pieces of DNA called operators. When bound to its operator, a repressor reduces transcription (e.g., by blocking RNA polymerase from moving forward on the DNA).

A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?
Answer:
The correct answer is - blue and red both.
Explanation:
Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.
Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.
RR mate with BB

B RB RB
B RB RB

tropical forests must be cleared to plant oil palms.
Explanation:
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
Non-renewable energy refer to a type of energy that is generated through artificial sources or that cannot be replenished. It includes coal, natural gas, fossil fuels, petroleum
Many environmental advocates believe that biofuel made from palm oil is not an appropriate replacement for fossil fuels such as petroleum because tropical forests must be cleared to plant oil palms. Palm fruits are region selective plants and as such wouldn't didn't thrive in regions other than tropical forests.

What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.
how is specific gravity extracted from the earth?

Crossing over occurs at the ends of chromosomes, rather than near the centromeres. As a result of crossing over, sister chromatids are no longer identical to each other. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA. Crossing over prevents homologous chromosomes from separating during meiosis I.

In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.
Explanation:

Explain how the oxidation of pyruvate links glycolysis with the citric acid cycle.
Pyruvate oxidation is the step that connects glycolysis to the citric acid cycle through the generation of acetyl-CoA.
The first thing that happens after glycolysis is that pyruvic acid passes from the cytoplasm to the mitochondrial matrix, crossing the membranes.
Pyruvic acid undergoes oxidation, a CO2 molecule is released and an acyl group (CH3-CO) is formed.
In this reaction, one molecule of NADH is formed, as in glycolysis the final product was two molecules of pyruvic acid, now two of NADH will be formed for each molecule of glucose.
Each acyl group binds to a Coenzyme A and acetyl Coenzyme A is formed, at this time the citric acid cycle begins.
Acetyl-CoA is degraded in the citric acid cycle to produce energy when cellular needs demand it.
Therefore, we can conclude that glycolysis achieves from the degradation of glucose to obtain 2 molecules of pyruvate, which is a previous step to give acetyl-Coa, which is the starting molecule of the citric acid cycle.

Why will doing a defibrillator cause the heart to pump ?
Answer:
it shocks the hearts muscles jolting the heart into working again.
Explanation:
Answer:
Defibrillation delivers an electrical shock that causes all the heart cells to contract at the same time. This stops the abnormal rhythm and allows the heart to restart normal electrical activity.

Explain mendel's experiment with peas on inheritence of characters considering only one visible contrasting character.
Ples answer in making points, it is for 5 marks.
➜ Mendel conducted breeding experiments with garden peas:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
Note: Here, F1 means First fillial generation and F2 means Second fillial generation.
Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.
