Answer: All animals, from humans to the dinosaurs are part of the carbon cycle. When animals eat food, they get carbon in the form of carbohydrates and proteins. The carbon combines with oxygen to form carbon dioxide [CO2] and is released back into the atmosphere as a waste product when animals breathe and exhale.

Explanation:

Both seals and sea lions, together with the walrus, are pinnipeds, which means "fin footed" in Latin.

But seals' furry, generally stubby front feet — thinly webbed flippers, actually, with a claw on each small toe — seem petite in comparison to the mostly skin-covered, elongated fore flippers that sea lions possess.

Secondly, sea lions have small flaps for outer ears. The "earless" or "true" seals lack external ears altogether. You have to get very close to see the tiny holes on the sides of a seal’s sleek head.

Third, sea lions are noisy. Seals are quieter, vocalizing via soft grunts.

Fourth, while both species spend time both in and out of the water, seals are better adapted to live in the water than on land. Though their bodies can appear chubby, seals are generally smaller and more aquadynamic than sea lions. At the same time, their hind flippers angle backward and don't rotate. This makes them fast in the water but basic belly crawlers on terra firma.

Sea lions, on the other hand, are able to "walk" on land by rotating their hind flippers forward and underneath their big bodies. This is why they are more likely to be employed in aquaria and marine shows.

Finally, seals are less social than their sea-lion cousins. They spend more time in the water than sea lions do and often lead solitary lives in the wild, coming ashore together only once a year to meet and mate.

Sea lions congregate in gregarious groups called herds or rafts that can reach upwards of 1,500 individuals. It's common for scores of them to haul out together and loll about in the sand, comprising an amorphous pile in the noonday sun.

Answer:

The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.

Explanation:

A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.

Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

Answer:

Small vessels that carry blood away from the heart to the capillaries are Arterioles. Muscular-walled vessels that carry blood away from the heart are Arteries. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are Capillaries. Small vessels that connect to the capillaries that carry blood back to the heart are Venules. Vessels that carry blood back to the heart are Veins.

Explanation:

We have different types of vessels in our bodies. We can divide them by their size and structure. Starting from the ones that carry blood away from the heath, we have the arteries. Arteries are vessels of big diameter that have muscle around them. Then, the arteries branch into arterioles, which have a smaller diameter. The arterioles branch into capillaries. These are small vessels with thin walls that allow the exchange of nutrients, wastes, and gases with the neighboring tissues. Once that the blood flows through the capillaries, it goes to the venules, which are small veins that will carry the blood to the veins and these to the heart. The veins do not have muscles in their structures, and their walls are thinner than the ones in the arteries.

The lagging strand cannot be replicated continuously, and the need for ligase to join the fragments best explains why ligase is necessary for DNA replication. Here option D is the correct answer.

DNA replication is the process by which a cell duplicates its DNA prior to cell division. It involves the synthesis of two new strands of DNA, the leading strand, and the lagging strand. The leading strand is synthesized continuously in the 5' to 3' direction, whereas the lagging strand is synthesized in short fragments called Okazaki fragments.

The lagging strand is synthesized in the opposite direction of DNA unwinding, making it necessary to synthesize it discontinuously. As the replication fork progresses, short Okazaki fragments are synthesized in the 5' to 3' direction away from the replication fork. However, these fragments are not yet connected to form a continuous strand.

This is where ligase comes into play. Ligase is an enzyme that plays a crucial role in DNA replication by catalyzing the joining (ligation) of the Okazaki fragments on the lagging strand. It forms phosphodiester bonds between adjacent nucleotides, sealing the gaps between the fragments and creating a continuous, double-stranded DNA molecule.

The correct option is (a). The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR).

The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR). BMR is the amount of energy that your body requires to maintain basic functions like breathing, circulation, and maintaining body temperature while you are at rest. It's influenced by factors such as age, gender, weight, body composition, and genetics. Basal metabolic rate (BMR) is a measure of how many calories the body uses when at rest. The basal metabolic rate is the minimum number of calories the body requires to sustain its vital functions, including heartbeat, respiration, and maintenance of body temperature, while at rest. This is typically measured while you are awake, but relaxed and in a fasting state. Basal metabolic rate (BMR) refers to the amount of energy that your body requires to maintain basic functions while at rest, and it is influenced by several factors. BMR accounts for around 60-70% of your total daily energy expenditure, which means that it plays a significant role in weight management. For instance, if you have a high BMR, you will burn more calories even when you are not active, which can help you lose weight or maintain a healthy weight. However, if you have a low BMR, you will burn fewer calories even when at rest, which can make it harder to lose weight.To calculate BMR, one needs to take into account their age, gender, weight, height, and body composition. The formula used to calculate BMR is different for men and women.

For instance, for men, the formula is BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years).

For women, the formula is BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years).

Knowing your BMR can help you determine how many calories you need to consume daily to maintain your weight or achieve your weight loss goals.

Explanation:

The percentage of white moths in the natural population in 1962, assuming the population was in Hardy-Weinberg equilibrium (HWE) for the G locus, is 20% (option D).

In Hardy-Weinberg equilibrium, the allele frequencies remain constant from generation to generation if certain conditions are met. For a single locus with two alleles, such as the G locus in this case, the equilibrium frequencies are p^2 for the homozygous dominant genotype (G/G), 2pq for the heterozygous genotype (G/g), and q^2 for the homozygous recessive genotype (g/g), where p and q are the frequencies of the two alleles.

If we assume that the white allele (g) is recessive and the brown allele (G) is dominant, and the percentage of white moths in 1962 is represented by q^2, then the value of q^2 is 20% or 0.20. Taking the square root of 0.20 gives us the frequency of the white allele (q), which is approximately 0.447. Since q represents the frequency of the recessive allele, the percentage of moths in the population that are white is approximately 44.7%, which is closest to option D (20%).

Selective reabsorption is the method through which components from the filtrate are transferred back into circulation. The correct answer is (B).

In the renal tubules of the kidneys, selective reabsorption takes place when urine is formed. The first stage of filtering takes place in the renal corpuscle, where blood is filtered into the renal tubules through the glomerular filtration barrier. As a consequence, a filtrate made up of water, ions, nutrients, and waste products is created.

Not every component in the filtrate, though, is a waste product that must be removed from the body. In order to sustain homeostasis, certain molecules, including glucose, amino acids, vitamins, and certain ions, must be reabsorbed into the circulation. Active or passive transport of these beneficial compounds from the filtrate in the renal tubules back into the peritubular capillaries surrounding the tubules is involved in selective reabsorption. This procedure aids in preserving vital chemicals and preventing the loss of urine.

Explanation:

From this experiment they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know. Since they have been accustomed to feeding from the feeder that is south they may continue to do so, but since it is not the farthest from the hive and there are other feeders located closer they may chose the new feeder. If they do decide to change feeder, then it tells the researchers that the Bees are able to calculate the distance and know that the new feeders are closer, while which feeder they choose might give them information on how bees determine direction.
