Given what we know about the water cycle we can confirm that the process that happening in the biome is the process of condensation
Although the water cycle can be divided and subdivided into various processes, we can simplify it into four simple steps:
EvaporationCondensationPrecipitation CollectionThe one saw in the biome and one of the most essential parts of the cycle is condensation. It is the collection of water molecules into a single group that, when dense enough, fall back onto the earth as rainfall. In nature these take the form of clouds, meanwhile, in the biome, they appear as water on the sides of the container.

in aerobic respiration, what is the ultimate fate of the electrons released from the breakdown of glucose?
Answers
Answer:
They are combined with oxygen and hydrogen ions to form water.
Explanation:
The electron released from the breakdown of glucose transfers in the electron transport chain and is used in the formation of a proton gradient across the membrane.
What is aerobic respiration?In the presence of oxygen gas, cells undergo cellular respiration, which is how energy from food is produced. The majority of plants, animals, birds, humans, and other mammals all engage in this sort of respiration regularly. As byproducts of this process, water and carbon dioxide are created.
The energy that was stored in carbohydrates and lipids during photosynthesis is released during the process of aerobic respiration and made available to living things. Glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation are the four phases.
Protons are pushed out of the matrix and into the intermembrane space as a result of the electrons moving through the electron transport chain. The electrons eventually reach oxygen, which reacts with protons to create water.

The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as
Answers
The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.
Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.
Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.
Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

Answers
An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----
The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown
They are therefore expected to produce heterozygous lines.
The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.
A dominant trait is known to mask the expression of other traits.

What is the term used to describe homologous chromosomes exchanging genetic material during meiosis?.
Answers
The term used to describe homologous chromosomes exchanging genetic material during meiosis is called crossing over.
CROSSING OVER:
Crossing over is the process whereby non-sister chromatids of homologous chromosomes (similar but non-identical chromosomes from each parent) exchange genetic material. Crossing over occurs in the prophase I stage of meiosis where homologous chromosomes lie side by side to form a structure called tetrad or bivalent. Crossing over ensures genetic diversity in the offsprings produced meiosis.Learn more about crossing over at: https://brainly.com/question/18824252?referrer=searchResults

visceral reflex arcs differ from somatic in that ________.
Answers
Explanation:
somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs.
The difference between visceral reflex arcs and somatic reflex arcs is that visceral turns require two motor neurons.
What are visceral reflex arcs?For instance, somatic reflexes require a direct link between the skeletal muscle and the ventral horn of the spinal cord. The central neuron of a visceral reflex sends a signal to a ganglion, which then sends another signal to the target effector.
While somatic reflexes are aware, visceral reflexes are unconscious. Compared to somatic reflexes, visceral reflexes entail a somewhat slower reaction time.
Visceral reflex arcs use two motor neurons along with glandular tissue and non-skeletal muscle to carry out a reflexive reaction. Skeletal muscles only have one motor neuron, therefore somatic reflex arcs include them.
Therefore, two motor neurons are involved in visceral arcs, which differ from somatic.

Mr. Allen wanted to fill balloons for a party. He rented a helium tank that contained 0.4 cubic meters of helium gas. He was concerned that the gas would not fill many balloons, but it filled 27 large balloons! Why was the small tank of helium gas able to fill so many balloons?
A. Helium mixed with air when it came out of the tank.
B. The helium expanded to fill its new containers, the balloons.
C. Helium molecules are very small in size.
D. The volume of gas in the balloons equaled the volume of gas in the tank.
Answers
Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.
Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.
This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.

what is the difference between ribose and deoxyribose
Answers
Ribose is a 5-carbon simple sugar. The chemical formula of this sugar molecule is H−(C=O)−(CHOH)4−H. This is the prime component of ribonucleic acid strands. It forms ribonucleotides.
Deoxyribose is a hexose sugar and is found in RNA. Deoxyribose binds a phosphate at the 2′ position. deoxyribose has one less oxygen molecule than ribose.
Deoxyribose, on the other hand, is a monosaccharide too. It also has the same 5-carbon formula as that of ribose sugar but loses an oxygen atom. Its chemical formula is H−(C=O)−(CH2)−(CHOH)3−H
