a) Produces and secretes hormones that regulate metabolism, growth, and development
b) Provides support and movement for the body
c) Breaks down food into nutrients and wastes
d) Supplies oxygen to blood and removes carbon dioxide from the blood”
The statement that best describes the function of the human body system in the given diagram is “Supplies oxygen to the blood and removes carbon dioxide from the blood”. Hence, option (d) is the correct answer.
The human body system in the given diagram is the respiratory system. The characteristics and function of the respiratory system are described as follows:
The respiratory system includes lungs, airways, and blood vessels It is the organs and tissues network that helps the individuals to breathe The primary role of the system is to move oxygen throughout the body with the help of blood and remove the waste gases like carbon dioxide from the blood that is obtained from various organsThus, we can conclude that the function of the respiratory system is defined by the statement " Supplies oxygen to the blood and removes carbon dioxide from the blood”. Hence, option (d) is the correct answer.

i need help with this can someone help me?
Explanation:
Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

Students are conducting a lab estimating the time it takes for the cell cycle in normal chicken cells. They find that the average time for one complete cell cycle is 22 hours.
What differences would they expect to see in cancerous chicken cells?
A Cancerous chicken cells will spend more time in interphase.
b Cancerous cells will not complete all phases of the cell cycle.
c Cancerous chicken cells will complete mitosis in a shorter amount of time.
d Cancerous chicken cells and normal cells will have the same total time to complete the cell cycle.
Answer:C!
Explanation:
Cancerous chicken cells will complete mitosis in a shorter amount of time.
The difference they would expect to see in cancerous chicken cells is cancerous chicken cells will complete mitosis in a shorter amount of time. The correct option is c.
What are cancerous cells?Cancerous cells are those cells that cause cancer in organisms. These cells are the converted form of normal cells. The normal cells are converted into cancerous cells by the means of mutagens.
The cell cycle is the cycle of the division of a cell. The cell divides itself and forms a new daughter cell. That's how a body increases the older cells to divide and produce new cells. The process is called mitosis.
Now, the normal cells divide at a constant and normal rate that is needed, but the cancerous cells divided abnormally and rapidly which cause tumor in the body.
Thus, the correct option is c. Cancerous chicken cells will complete mitosis in a shorter amount of time.

Which property of water explains how water droplets are absorbed by a paper towel?
Water's adhesion to other types of molecules
Water's high heat of vaporization
Water's high surface tension
Water's buffering capacity
Answer:
A. water's adhesion to other types of molecules
The property of water that explains how water droplets are absorbed by a paper towel would be its adhesion.
Adhesion refers to the force of attraction between the molecules of different substances. It is as opposed to cohesion which is the force of attraction between the molecules of the same substance.
When the adhesive force between water molecules and the molecules of another substance is greater than the cohesive force between water molecules, water will stick to such a substance. If the reverse were to be the case, water will not stick to the substance. Instead, the water molecules will form droplets on the substance.

A strand of messenger RNA is attached to a ribosome and is directing protein synthesis. The next exposed codon of this messenger RNA has the code GAA. It is most likely to bond with a transfer RNA that has which amino acid?
Answer:
Glutamic acid or Glutamate
Explanation:
This question is describing the process of TRANSLATION, which is the process by which protein is synthesized from a mRNA template. In the process of translation, a molecule called transfer RNA (tRNA) reads mRNA codons and carries its corresponding amino acid to the growing polypeptide chain.
According to this question, strand of messenger RNA is undergoing translation in the ribosome. However, the next exposed codon of this messenger RNA has the code GAA. A tRNA carrying an amino acid that corresponds to the codon GAA will attach to it. This amino acid is GLUTAMIC ACID.
N.B: codon GAA encodes amino acid GLUTAMIC ACID

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

A population of rabbits lives on one side of a wide river. Another population of rabbits lives on the opposite side of the river. They cannot cross the river. If speciation occurred as a result of the river, what kind of speciation was this? ___________
Answer:
Allopatric speciation
Explanation:
The kind of speciation that occurs when 2 populations of rabbits separated by water become different species is allopatric speciation.
Allopatric speciation occurs when two populations of the same organisms become physically separated and each population ends up developing unique characteristics that make them distinct species. This is as opposed to sympatric speciation in which a new species just spontaneously emerge from the existing population without any being separated from the population.
Other forms of speciations include parapatric speciation which occurs as a result of the spreading out of a population over a large geographical area and peripatric speciation which occurs as a result of the breaking off of a small group from a large group of organism.
In the illustration, the two populations of rabbits are separated physically by the river. Hence, the speciation that will occur if each population goes ahead to form a new species would be allopatric speciation.

The image shows a spruce tree, which is a gymnosperm.
Which characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant?
naked seeds
green leaves
thick bark
tall height
Answer: Naked Seeds
Explanation:
Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.
What is gymnosperm?Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."
Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.
This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Therefore, option A is correct.
