Chromatin plays a important role in metabolism of cell and it regulates the genetic activities of the cell as well. To create chromosomes, chromatin fibers are coiling and condensing. Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.

So, for genome replication, transcriptional silencing, DNA repair, and recombination, chromatin architecture is essential.

DNA molecule bonding is Alternating

The best description of arrangement of the sides of the DNA molecule bonding is; Alternating.

The DNA molecule is made up of of two strands that are wound around one another to form a shape known as a double helix.

The double-helix can be compared to a twisted ladder and is therefore categorised as alternating.

Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

Explanation:

Answer: Like humans, dogs need to keep themselves cool to protect their bodies. They do sweat, but not in the same way. They only have sweat glands only on the paw pads and nose leather. Since they are covered with fur, it is more challenging to keep their bodies cool.

After your dog runs around, you will notice that he begins to pant heavily. Dogs rely on panting to keep their bodies cool. Panting causes the evaporation of water from the nasal cavity, tongue, throat and lungs, which helps lower their body temperature.

They also experience the same dilation in blood vessels as humans, which brings blood to the surface of the skin, allowing the air in the environment to cool them.

Any dog is at risk for heat-related problems, especially in warm, humid weather. Our brachycephalic friends are at a much greater risk than their long-nosed counterparts. Large breeds with thick coats, such as Bernese Mountain dogs or Pyrenees are also more prone. Dogs with pre-existing heart conditions or respiratory issues are also more likely to be overcome by the heat.

When these dogs pant to try and cool themselves, they have to work harder to do so. This only raises their body temperature even higher, making it worse instead of better.

Photosynthesis is a biological process that occurs in plants, algae, and some bacteria. It is the process by which these organisms convert light energy from the sun into chemical energy in the form of glucose (a type of sugar).

The human heart muscle cell has more mitochondria than a skin cell because it needs more energy. Muscle cells need more energy to function which the mitochondria produces.

One reason why a human heart muscle cell would probably contain a higher proportion of mitochondria than a skin cell is mitochondria.

Each cardiac muscle cell, or cardiomyocyte, is a tubular structure made up of chains of myofibrils, which are rod-like components inside the cell. Sarcomeres, the primary contractile units of muscle cells, are repeated in sections to form the myofibrils.

Because it requires more energy, the human heart muscle cell has more mitochondria than a skin cell. To function, muscle cells require extra energy, which the mitochondria produce.

Therefore, human heart muscle cells are likely to have a higher percentage of mitochondria than skin cells for a number of reasons, including mitochondria.

For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.

Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.

In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

At a pH of 8, all the molecules as unfastened amino acids could have at the least one advantageous and one poor price, because the carboxylic acid could have a -1 price and the amino terminus could have a +1 price. According to the given table, arginine and glutamic acid may even have charged facet chains. Free amino acids include at the very least  companies which could come to be charged. The first is the carboxylic acid terminal, which exists as neutral -COOH whilst protonated and negatively-charged -COO− whilst deprotonated. The 2d is the amino terminal, which turns into the positively-charged -NH3+ whilst protonated and the neutral -NH2 whilst deprotonated. Note that "protonated" isn't constantly synonymous with "advantageous." A protonated role may be both advantageous or neutral, relying at the institution in question.

Every cell in your body has DNA, which is the form in which your genetic code is stored. It creates your body's manual of operations. Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.

A chromosome is referred to be a "homologous chromosome" if it has a similar genetic makeup but also includes replication-induced variations. Sister chromatids are the two halves of a certain chromosome that are joined at the centromere. Chromosomes known as "replication chromosomes" arise after the cell has undergone the process of DNA replication to prepare for cell division.

Answer:

D. Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

Explanation:

Adaptation does not happen overnight, and humans didn't breed foxes to have white fur. Smaller ears and noses allow less exposure to the cold because of their smaller surface area, which prevents heat loss. Foxes with smaller noses and ears didn't die of hypothermia, which allowed them to survive and breed and pass their genes to their offspring.

Human activity has caused trophic cascades in several species, with one notable example being the reintroduction of gray wolves to Yellowstone National Park in 1995.

Prior to their reintroduction, the park's ecosystem had suffered due to the absence of wolves, as their absence had allowed the elk population to grow unchecked, resulting in overgrazing of vegetation and a decline in biodiversity.

Once the wolves were reintroduced, they began to prey on the elk, which reduced the elk population and allowed vegetation to recover. As a result, the habitat of other species, such as beavers, songbirds, and even fish, improved, as they were able to utilize the newly regenerated vegetation.

This is a classic example of a trophic cascade, where the removal or addition of one species can have a cascading effect on the rest of the ecosystem.

Human activities such as hunting, deforestation, and pollution have disrupted many ecosystems, causing trophic cascades that can have far-reaching consequences for biodiversity and ecosystem functioning.
