Answer:

hope it helps have a nice day

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: Because desserts are very hot, we know that there aren't much plants due to the lack of rain/water, they're dry. Rainforests have lots of plants, so it's not B, and since the dessert is high temperature, A is obviously off the list.

Taiga is cold so it won't be good for soil and the plants won't grow as good as the wet rainforest so we can pick A. Then B for #2

assuming that the population was in HWE for the G locus, what percentage of moths in the natural population was white in 1962?
A. 2%
B. 4%
C. 8%
D. 20%
E. 64%

Answers

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%).

Which of the following best explains why ligase is required for DNA replication?
Ugase facilitates the binding of RNA polymerase to the promoter region.
Ligase enables the newly synthesized DNA to twist into a double helix
Ligase forms the hydrogen bonds between complementary bases in the two strands of DNA
The lagging strand cannot be replicated continuously, and ligase is needed to join the fragments

Answers

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.

How do you suppose changes in DNA lead to speciation

Answers

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.

Muscular-walled vessels that carry blood away from the heart are _______. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are _________. Small vessels that connect to the capillaries that carry blood back to the heart are ________. Vessels that carry blood back to the heart are _________.

Answers

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.

Materials are returned to the blood from the filtrate by which of the following processes?
A. filtration
B. selective reabsorption
C. excretion
D. secretion

Answers

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.

What are chromosomes?
a.)
A condensed form of DNA that occurs when the cell is dividing
b.)
A form of uncondensed DNA found within the nucleus of the cell
c.)
A structure found within the nucleus that produces subunits of ribosomes
d.)
A cell organelle that houses the DNA and controls activity within the cell

Answers

A condensed form of DNA that occurs when the cell is dividing, option (a) is correct.

Chromosomes are condensed structures of DNA that occur when the cell is dividing. During cell division, DNA molecules undergo a process of condensation and coiling, resulting in the formation of visible chromosomes. These structures contain genetic information in the form of genes. Chromosomes ensure that genetic material is evenly distributed to daughter cells during cell division.

They consist of a central region called the centromere, which plays a role in the separation of chromosomes during cell division, and two arms known as chromatids. Each chromatid contains a copy of the DNA molecule. Chromosomes are temporary structures that revert back to an uncondensed form of DNA called chromatin during interphase, the non-dividing phase of the cell cycle, option (a) is correct.

Researchers allow bees to feed from a feeder located 500 meters due south of the hive for several days in a row. They then place a new feeder due south of the hive and place feeders in several other directions from the hive as well, but all are now 450 meters from the hive. They leave the original feeder empty. Next, they determine which feeders that new bees from the hive now visit. What information can they learn from this experiment alone

Answers

Answer:

they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know.

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.

Name 4 morphological and 2 behavioral traits that can distinguish between a seal and a sea lion.

Answers

Answer:

#HEY MATE HERE IS YOUR ANSWER#

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.
