Answer:

Thermal energy can be transferred by conduction, convection or radiation

Explanation:

Thermal energy is the energy that flows from one point to another due to temperature differences between the points. There are three ways by which thermal energy is transferred which are conduction, convection and radiation.

In conduction, thermal energy is transferred in solids usually metals due to their good heat conductivity. An example is seen in the use of metals for preparing meals. Heat (or thermal energy) is transferred from the fire to the metal to the food.

Convection occurs in fluids (liquids and gases). It usually occurs in a cyclic manner. For example in heating water, thermal energy is gained by water molecules closest to the heat source (at the base of the container) and become lighter causing them to rise to the top. The molecules at the top become denser and sink to the bottom whereby they gain energy and rise in a similar manner. This repeated phenomenon occurs in a cyclic form whereby there's displacement of colder and denser molecules by warmer and lighter molecules. Another example is the occurrence of sea and land breezes.

Radiation occurs without the need of any material medium unlike conduction and convection. In radiation, heat is directly transferred from one point to the other without being transferred by molecules. This is seen in how thermal energy from the sun reaches the earth. In other words, heat is transferred in a vacuum

The codon is a triplet of nucleotide bases in an RNA chain that code for amino acids during the process of translation.

During translation, the tRNA reads the mRNA sequence in triplet of nucleotides which is called as codon which is then used to decipher the amino acid to be added in the polypeptide chain.

As there are 20 amino acids, there is a redundancy of the codons, that is, many codons can code for one amino acid.

There is one codon that is always present at the beginning of the RNA which is called the start codon which is AUG. It initiates the translation process.

At the end of the RNA sequence is the stop codon which is UAA, UAG or UGA which bring the translation process to an end.

The codons given correspond to the following amino acids:

1. AUG - Methionine

2. GAA - Glutamic acid

3. CGG - Arginine

4. UGA - Stop codon

Since the observed percentages are very close together as less than 3 percent apart, it is just due to random chance.

The observed discrepancy between the percentages of the two groups might just be a matter of chance. The medical word for inflammation (swelling) of the sinus and nasal lining is rhinosinusitis, or more often, sinusitis.

The face bones' hollow spaces that connect to the nasal passages are known as the sinuses. Like the inside of the nose, the sinuses are lined by mucous membranes. There were no differences in the compared treatments for illness complications, disease recurrence, or study dropouts due to adverse events.

The role of both sexes in fulfilling the function of the reproductive system is to produce gametes. Therefore, option (B) is correct.

Both males and females produce specialized reproductive cells called gametes. In males, these gametes are sperm cells, while in females, they are egg cells or ova. The production of gametes is essential for sexual reproduction as it allows for the fusion of sperm and egg during fertilization, resulting in the formation of a zygote and subsequent development of an embryo.

While the reproductive systems of males and females have additional functions and roles, such as the production of hormones, maintenance of homeostasis, and support for the growth and development of the embryo and fetus, the fundamental role shared by both sexes is the production of gametes for sexual reproduction.

Option 3 is Correct. When natural selection favors two or more extreme phenotypes that each have a distinct advantage, this process is known as 'diversifying' or 'disruptive selection,' which increases genetic diversity.

Natural selection that favors phenotypic extremes is known as disruptive selection. This indicates that intermediates are the target of active selection. In contrast to stabilizing selection, it promotes genetic variety. When conditions favor individuals at both ends of a phenotypic spectrum over those with intermediate traits, this is known as disruptive selection.

The average phenotype of the trait is minimized and the two extreme phenotypes of the trait are favored by disruptive selection (diversifying selection). Disruptive selection is therefore the reverse of stabilizing selection in the result since it leads to a bimodal distribution of a characteristic in the population.

Sciatica is indeed a painful condition resulting from pressure on the sciatic nerve, leading to pain sensations that radiate down the leg. The sciatic nerve is associated with the lumbosacral plexus, which is a network of nerves that arises from the lumbar and sacral regions of the spinal cord. This plexus plays a vital role in the functioning of the lower limbs, as it provides motor and sensory innervation to various muscles and skin areas.

The lumbosacral plexus is formed by the anterior rami of spinal nerves L1 to S4, and it is divided into the lumbar plexus and the sacral plexus. The sciatic nerve, specifically, is the largest nerve arising from the sacral plexus. It is composed of two distinct nerves, the tibial nerve and the common fibular (peroneal) nerve, which are enclosed within the same connective tissue sheath.

The sciatic nerve emerges from the pelvis through the greater sciatic foramen and descends into the posterior thigh, providing innervation to the hamstrings and other muscles in the leg. It is responsible for transmitting signals related to movement and sensation between the spinal cord and the lower limb.

In summary, the sciatic nerve is associated with the lumbosacral plexus, specifically the sacral plexus. Pressure on the nerve can lead to sciatica, causing pain and discomfort that radiates down the leg.
