Which situation is an example of competition that could be found in the ocean?


two shark populations utilize the same fish population as their main food source


algae blooms decrease as the number of fish increase


lack of sunlight due to changes in the seasons restricts the growth of certain plants


plentiful oxygen leads to an increase in the number of reefs

Answers

Answer:

A. two shark populations utilize the same fish population as their main food source

I'm guessing this is from Marine Biology. I know this is an example of competition because two different groups of sharks are eating food from the same source. If one group gets to it first every time, they could leave the other group with no food. So it is a competition.

Answer:

two shark populations utilize the same fish population as their main food source

In a high pressure system, cool air ____________ and warms, and the weather is ____________ and ____________.

Answers

Answer:

Sinks; clear: dry.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

The air pressure gradient which typically is the difference in air pressure between two systems affects the movement of atmospheric air. Consequently, this movement has a significant level of impact on the type of weather that is formed between low-pressure and high-pressure systems.

In a high pressure system, cool air sinks and warms, and the weather is clear and dry. Similarly, in low-pressure systems, warm air usually rises and then cools, thus, leading to the formation of clouds and precipitations.

A cell undergoing meiosis has a defect and cannot do crossing over. The cell
completes the rest of meiosis successfully and produces four sperm cells.
Which of the following describes the correct outcome of this defect?
Select one:

The sperm cells will all be the same.

The sperm cells will be identical to the parent cell.

The sperm cells will have reduced genetic variety but will still be different.

The sperm cells will form two pairs of identical cells. Cells in a pair will be different from
the other pair

Answers

Answer:

Option #3

Explanation:

That is the basic terminology that us used during meiosis.

The statement that best describes the correct outcome of this defect is the sperm cells will all be the same. Thus, the correct option for this question is A.

What is Meiosis?

Meiosis may be defined as a type of cell division that significantly produces four daughter cells that are genetically non-identical to the parental cells. These daughter cells are haploid in nature. Germ cells or sex cells are generally produced by this mechanism.

The cells that are formed as a result of meiosis have half the amount of chromosomes as compared to the parental cell. This is because when the germ cells of two different origins fuse together, they will form complete chromosomes.

The egg cells or sperm cells that are produced by this process of cell division will all be the same with respect to the number of chromosomes and physiology along with function.

Therefore, the sperm cells will all be the same is a statement that best describes the correct outcome of this defect. Thus, the correct option for this question is A.

what's the difference between the structure of a nucleic acid and the structure of a protein? ​

Answers

There are two principle differences between the structures of proteins and nucleic acids:

Monomer Composition
Eventual Conformation

The first involves the chemical makeup and bonding pattern of individual monomers of each polymer, those monomers being amino acids in proteins and nucleotides in nucleic acids. Amino acids consist of an amine and carboxyl functional group along with a side chain (commonly referred to as an R group), with the amine and carboxyl groups involved in “linking.” Nucleic acids are of quite a different chemical makeup, composed of a five-carbon sugar and phosphate group backbone, both involved in chaining, from which protrudes a nitrogenous base.

The second involves the “destiny” of the polymer in regards to conformation. A protein’s eventual conformation is always consequential, resulting from interactions between the R groups of its amino acid monomers. Nucleic acids, on the other hand, possess the notable structure of strands. RNA’s case is one of a single strand, while DNA’s is a double-helical arrangement of two.

Why does embryology suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common.

Answers

Answer:

In the examination of the embryological stages of various organisms, it appears to be very similar in their structure, for instance, all vertebrate embryos have gill pouch and that evolved in gills in fish and head and neck in others.

The tail of the vertebrates is also an example that is present during the embryological stage but later regressed in human and other have them. On this basis, it can be stated that embryology suggests an evolutionary relationship.

Anna studies the color of her bedroom wall using different lights. In sunlight, she sees that the wall is white. Anna darkens the room and shines a beam of light that includes all the wavelengths of visible light onto the wall. In this light, what's the wall color that Anna sees?

Answers

Answer:

White

Explanation:

The light is measured by its wavelength, generally in nanometers (nm), and visible light has a wavelength spectrum of 400 to 700 nm. Sunlight can be divided into three components: 1-visible light, 2-ultraviolet (UV) light, and 3-infrared radiation. Since white light is visible light (this color contains all the colors of the rainbow) and sunlight includes the visible light of all wavelengths, the object will look white under this light spectrum.
