D. storage of materials
Answer:
A. collection of waste material or diffusion of material
Explanation:The walls consist of a very thin layer of epithelial tissue encased in a moist membrane which enables the diffusion of nutrients and oxygen out of the blood and the diffusion of waste products into the blood
Capillary walls are only one layer thick cell layer. Passage of oxygen in and out of the capillaries is controlled mostly by the process of collection of waste materials. Thus, the correct option is A.
What are blood vessels?
Blood vessels are the channels through which blood is distributed to all the body tissues. The vessels make up the two closed systems of tubes that begin and end at the heart. One system is the pulmonary vessels, which transports blood from the right ventricle to the lungs and back to the left atrium.
There are three types of blood vessels which are arteries, veins, and capillaries. These vessels plays a very specific role in the circulation process in the body. Arteries carry the oxygenated blood away from the heart to the other tissues. Veins carry the deoxygenated blood form the body tissues to the heart and lungs and capillaries make the passage between these blood vessels.
Therefore, the correct option is A.

Why would an airplane flying at 10,000 meters above the ground have more gravitational potential energy than the same airplane flying at 1,000 meters above the ground?
Answer: because the
Explanation: A flying airplane has potential energy has it flies above the ground level. And since the airplane is flying motion is associated with it and thus possesses kinetic energy.
The plane at 10,000 m will have more gravitational potential energy because it is directly proportional to height.
What is gravitational potential energy?
The energy stored by an object as a result of its position is called potential energy.
When an object is at a height, it is able to store gravitational potential energy. This energy is because of the attractive force of gravity acting on the object as a result of its height.
Gravitational potential energy is mainly dependent on two factors. These are - the mass of the object held at a height and the height at which it is held i.e the vertical distance between the object and the earth.
Gravitational potential energy is equal to
P E = m × g × h
Where m is the mass of the object
g is the acceleration due to gravity
h is the height
Therefore, gravitational potential energy is directly proportional to the mass of the object and the height at which it is held.
Since in the above case, we are talking about the same airplane so mass will be common. But at a height of 10,000m gravitational potential energy will be considerably higher compared to at a height of 1000 m.

How does slow movement aid sloths in acquiring food?
Answer:
Sloths are so slow moving that algae is able to grow symbiotically in their fur. This algae can be licked out of the sloth's fur to provide it with nourishment.
Explanation:
The slow movement aid sloth in acquiring food, as slow and limited movements need less food and nutrition. It also helps in digesting food and the metabolism also works slowly.
What are sloths?Sloths are arboreal Neotropical mammals that are very slow-moving and are herbivores, they eat leaves and algae, and twigs. They live in evergreen forests and tropical rainforests.
They are so slow that algae grow above their furs, which helps them camouflage between green forests from predators. Because they are quite adept at concealment. They not only live nearly entirely in trees and only venture out if absolutely necessary, but they also harbor algae in their fur that help them blend in.
Therefore, due to their limited and slow movements, sloths require less food and nutrition when foraging for food. Additionally, it aids in food digestion and slows down metabolism.

how many years would it take a radio signal from the exoplanet wolf 359 to reach earth? Wolf is 7.9 light years from earth.
Answer:
Radio waves move at the speed of light which is aproximately 300,000 km per second or 3.8*10^8 m/s
1 ly = 9.461*10^15 m
Then
7.9 light-years = 7.4*10^16 m
By, velocity = distance/ time
time = distance/time
t = 7.4*10^16/3.8*10^8
= 1.9473684*10^24 seconds
Converting seconds to years (1 year = 31536000 seconds)
1.9473684*10^24/ 31536000 years
=6.17096989 ×10^16 years
How does heat gases cause increase in pressure
Answer:
When a gas is trapped inside a container which has a fixed size (its volume cannot change) and the gas is heated, the particles will gain kinetic energy which will make them move faster. This causes the force on the walls of the container to increase and so the pressure increases.

Answer:
Mitosis
Explanation:
Mitosis is a type of cell division where the cell replicates its DNA and splits into two identical daughter cells. This occurs in some types asexual reproduction or in cell proliferation.
Meiosis produces genetically diverse daughter cells with half the amount of DNA as the parent. It occurs as part of asexual reproduction.
During budding, the cell divides asymmetrically as part of asexual reproduction.
Symbiosis is when two organisms interact with one another, and is usually benefit to both of them. It is not a type of cell division

Mitosis
Explanation:
A new organism develops from a small bud that forms on the parent. It grows into a copy of the parent through mitosis.
g The Drosophila melanogaster genome contains approximately 24 million bases of exon sequence, 20 million bases of intron sequence, and 76 million bases of intergenic sequence. Calculate and compare the percentages of exon and intron sequences in Drosophila melanogaster genome to that of the human genome.
Answer:
When it is compared to the human genome, the Drosophila melanogaster genome contains a higher proportion of exons (20%) and a minor proportion of introns (16.6%).
Explanation:
The Drosophila melanogaster genome contains 24 million bases (Mb) encoded by exons + 20 Mb introns + 76 Mb intergenic sequences = 120 Mb >>
- Exon sequences= (24 x 100)/120: 20 %
- Intron sequences= (20 x 100)/120: 16.6 %
- Intergenic sequences= (76 x 100)/120: 63.3 %
On the other hand, the completion of the human genome sequencing showed that only 1.1% encodes proteins (i.e., they are exons), 24% are introns, and 75% are intergenic sequences. Moreover, it is also important to highlight that the D. melanogaster genome contains about 13,000 protein-coding genes, while the human genome contains nearly 22,000-30,000 protein-coding genes.

Explain how a carbon atom in carbon dioxide becomes a hydrocarbon and organic compound before becoming carbon dioxide again.
Answer:
See below
Explanation:
Used in photosynthesis to become glucose, converted into glycogen in the body. Lipogenesis then converts it into fat, which is then again metabolized in respiration to become CO2
Carbon dioxide is consumed by plants and converted into hydrocarbon compound glucose by photosynthesis and during cellular respiration, hydrocarbon is released to carbon dioxide again to release into the atmosphere.
What is photosynthesis?Water and carbon dioxide are converted into oxygen and glucose in photosynthesis, plant takes glucose and generates oxygen as a byproduct.
Oxygen and glucose are converted into water and carbon dioxide in cellular respiration. The by-products of the process include carbon dioxide, water, and ATP, which would be turned into energy.
During cellular respiration, hydrocarbon is released to carbon dioxide again to release into the atmosphere. The process of respiration involves the production of carbon dioxide and water as a result of the breakdown of carbohydrates.
Therefore carbon dioxide is converted to hydrocarbon and during cellular respiration is again released as CO2.

When plasmids are mixed with histones, they will bind fewer histones than the equivalent length of linear DNA. Upon addition of a topoisomerase, more histones will be bound. Explain this observation.
Answer:
Topoisomerases relax the positive supercoil of the plasmid when histones bind, thereby allowing for more histones to bind.
Explanation:
Plasmids are closed-circular DNA. Unlike linear DNA which can bind a greater number of histone molecules due to greater freedom of rotation, when plasmids binds to a histone molecule, a negative supercoil is introduced in the plasmid. However, since the plasmid is closed and the DNA is not broken, a compensatory positive supercoil in the unbound region of DNA is introduced. This limits further binding of histone molecules to the plasmids.
However, with the introduction of topoisomerases, they relax the positive supercoils, thereby stabilizing the negative supercoil. Further binding of histone molecules are initiated with the formation of negative supercoils and relaxing of positive supercoils result in more histone molecules bindingd to the plasmids.

5. what is the difference between intercellular communication and intracellular communication?
6. what are plasmodesmata?
Answer:
Cells are the basic building blocks of all living things. ... Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus.
Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located.
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
What is the difference between intracellular signaling and intercellular signaling? Intracellular signaling occurs within a cell, and intercellular signaling occurs between cells.
