The structure of nucleic acids,  DNA and RNA, is formed by their sugar-phosphate backbone. The directionality of molecule is determined by its backbone, which is made up of alternating groups of sugar, phosphate.

In biological processes, energy is frequently stored or transferred via sugar phosphates (that have extra or replaced phosphate groups). They also serve as the foundation for DNA and RNA. Near the modified nucleotides, the sugar phosphate backbone shape is changed.

The multiplex electrical structure of the sugar-phosphate backbone makes a theoretical explanation challenging. Across the entire backbone, a portion of the electronic density is delocalized, and the degree of the delocalization is influenced by the backbone's conformation due to hyper-conjugation effects. Localized orbitals at the 1,3 positions interact with donors and acceptors to produce hyper-conjugation.

Explanation:

Order:

I-bare rocks,

II-pioneers (mosses, lichen, algae, fungi)

III-annual herbaceous plants

IV-perennial herbaceous plants and grasses

V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

(please mark me brainliest) :)

Lichens, hearty shrubs, and trees is the correct order in which the organisms return to an ecosystem during primary succession after an area's ecosystem has been wiped out. Thus, the correct option is C.

Primary succession is the ecological succession which begins in essentially the lifeless areas, such as the regions in which there is no soil or where the soil is incapable of sustaining life where no life form ever existed because of recent volcanic eruption, newly formed sand dunes, or rocks that are left from a retreating glaciers.

The correct order of the Primary Succession is:

Stage I- Bare rocks,

Stage II- Pioneer species such as mosses, lichen, algae, and fungi

Stage III- Annual herbaceous plants

Stage IV- Perennial herbaceous plants and grasses

Stage V- Shrubs, shade intolerant trees, and shade tolerant trees.

The transcript of the gene that creates the protein is known as messenger RNA (mRNA). The transcription of the DNA sequence results in the production of mRNA.

The DNA sequence and the mRNA sequence are complementary, which means that the mRNA sequence is the DNA sequence's reverse complement. The nucleotides are organised in the 5'-3' orientation in the provided DNA sequence. The nucleotides must be read in the 3'–5' orientation in order to get the mRNA sequence.

As a result, the mRNA sequence is AGACTGCCATGAAGTT. Because the mRNA sequence is composed of the DNA sequence's complementary nucleotides, it is the reverse complement of the DNA sequence.

For instance, the DNA sequence's first nucleotide, T, and its complementary nucleotide, A, which is the This is the mRNA sequence's first nucleotide. The second nucleotide of the DNA sequence is A, while the second nucleotide of the mRNA sequence is U, which is complementary to A. The sequence is consistent with this pattern.

The two glands found in the sheep brain are the pituitary gland and the pineal gland. The pineal gland is found outside the dura mater.

The pituitary gland, also known as the "master gland", is a pea-sized gland located at the base of the brain that secretes hormones that regulate various bodily functions such as growth, reproduction, and metabolism. The pineal gland, located near the center of the brain, produces the hormone melatonin, which helps regulate sleep-wake cycles and other circadian rhythms. Unlike the pituitary gland, which is located within the protective bony structure of the skull, the pineal gland is located outside the dura mater, which is the outermost of the three layers of protective tissue surrounding the brain and spinal cord.

What is sympathetic nervous system?

A network of neurons in your body called the sympathetic nervous system aids in the "fight-or-flight" reaction. When you're under stress, in danger, or engaged in physical exercise, this system becomes more active. Its effects include accelerating respiration and heart rate, enhancing vision, and slowing down bodily functions including digestion.

The sympathetic nervous system regulates the muscles that enlarge the pupil.

The mother is the parent that gave the boy the colorblind gene.

In humans, color blindness is a recessive, sex-linked trait that is carried on the X chromosome.

Since males only inherit one X chromosome from their mother and one Y chromosome from their father, they are more likely to express sex-linked recessive traits if they inherit the affected allele from their mother.

In this scenario, the boy's father is colorblind, which means he must have inherited the colorblind gene from his mother since his father could not have passed it on to him (his father could only pass on the Y chromosome to him).

The mother is not colorblind, which means she must have inherited at least one normal allele for color vision. Since the boy is colorblind, he must have inherited the colorblind allele from his mother, who must be a carrier for the trait.

Therefore, the balanced equation is 4C2H5F + 13O2 -> 8CO2 + 10H2O + 2F2.

We need to determine the appropriate coefficient for the O2 molecule.

To balance the equation:

4C2H5F + __O2 -> 8CO2 + 10H2O + 2F2

We need to determine the appropriate coefficient for the O2 molecule.

Let's start by balancing the carbon (C) atoms. There are 4 C atoms on the left side (4C2H5F) and 8 C atoms on the right side (8CO2). To balance the C atoms, we need a coefficient of 2 in front of the C2H5F compound:

4C2H5F + __O2 -> 8CO2 + 10H2O + 2F2

Next, let's balance the hydrogen (H) atoms. There are 10 H atoms on the right side (10H2O). To balance the H atoms, we need a coefficient of 5 in front of the H2O compound:

4C2H5F + __O2 -> 8CO2 + 10H2O + 2F2

Now, let's balance the fluorine (F) atoms. There are 4 F atoms on the left side (4C2H5F) and 2 F atoms on the right side (2F2). To balance the F atoms, we need a coefficient of 2 in front of the C2H5F compound:

4C2H5F + __O2 -> 8CO2 + 10H2O + 2F2

Finally, let's balance the oxygen (O) atoms. There are 16 O atoms on the right side (8CO2 + 10H2O). To balance the O atoms, we need a coefficient of 13 in front of the O2 molecule:

4C2H5F + 13O2 -> 8CO2 + 10H2O + 2F2

Therefore, the balanced equation is:
