Explanation:

The nucleotides which are found in the DNA molecule are made up of nucleoside moieties and phosphate molecule. These are of five types which include adenosine, guanosine, uracil, thymine, and cytosine.

Nucleotides are the organic molecules which consist of a nucleoside and a phosphate moiety. The nucleotide molecules serve as the monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all life forms on the Earth.

A nucleotide is one of the main structural components, or the building blocks, of DNA and RNA molecules. A nucleotide consists of a base which has one of four nitrogenous base which could be purine and pyrimidine such as adenine, thymine, guanine, and cytosine plus a molecule of sugar and one molecule of phosphoric acid.

Answer:

newborn infants. Bioassayable andimmunoassayable renin activities were elevated during the first six days after delivery. At 3 to 6 weeks of age, although elevated above that in adult control subjects, renin activity was lower than in the first postnatal week. Cord blood renin values were greater than those for maternal renin during labor. Renin substrate concentration was elevated in infants less than six days of age and also in 3- to 6-week-old infants. The enhanced activity of the renin-angiotensin system may contribute to the increased renal vascular resistance and the altered renal hemodynamics that occur in the newborn infant.

Answer:

A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.

Explanation:

The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.

Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.

This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

Explanation:

Crabs, pilchards, blennies and snappers are the examples of secondary consumers.

Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.

They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.

This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.

Answer:

Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.

Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.

However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.

The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.

The lens is normally clear and is located behind the iris. The pupil directs light to the lens.

Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.

Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.

The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).

Thus, eye lens helps to focus the object.

6. As the lunar cycle progresses from the full moon to new moon the light will appear to decrease

7. The “growing light” that appears during the first half of the lunar cycle is referred to as waxing.

8. The third quarter / 7th phase occurs at 21 days into the cycle and shows the left half of the moon illuminated.

9. In a crescent stage less than half of the Moon appears illuminated and during a gibbous stage more than half appears illuminated.

Explanation:

The "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

It has much significance and is related to the moon, which is a natural navigation aid for mariners, providing light at night and it has an impact on the life cycles of animals and plants, including breeding and migration, and the gravitational pull of the moon and the sun causes the tides to rise and fall.

Hence, the "growing light" that appears during the first half of the lunar cycle is referred to as the "waxing phase" ,the first quarter phase occurs 21 days into the cycle and in the crescent stage, less than half of the moon appears illuminated.

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

Explanation:

The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.

The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.

The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.

RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.
