The graph here shows a population of rabbits in an ecosystem that the rabbits are not allowed to enter or leave

A. The death rate is very high.
B. It has access to more resources than it needs
C. The population density is very high.
D. There is great competition for resources.

Answers

Try B I’m not too sure

The statement that is most likely to be true of the rabbit population in an ecosystem at point A is it has access to more resources than it needs. Thus, the correct option is B.

What is an Ecosystem?

An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.

The death rate of any population is high when this population crosses the limit of carrying capacity. And here, point D represents this scenario, so option A is incorrect.

Population density is the measurement of individuals of any species at a specific geographical location, so option C is also incorrect.

The competition for resources is significantly high when the population of any species almost reaches the carrying capacity. And here, point C represents this scenario, so option D is also incorrect.

Therefore, the statement that is most likely to be true of the rabbit population in an ecosystem at point A is it has access to more resources than it needs. Thus, the correct option is B.

When comparing animal to plant cells, they are different in size, shape, and how they store energy. They have similarities, as well. Which organelles perform similar functions in both plant and animal cells. Group of answer choices D. Ribosome, cell membrane, chloroplast C. Cell membrane, cell wall, nucleus

Answers

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.

Which structural characteristics describe a DNA molecule

Answers

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

What would happen on a hot day if your brain did not receive input that your body was starting to heat up

Answers

Answer:

The body will overheat

Explanation:

If the brain of an individual does not receive input that the body was starting to heat up on a hot day, the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating.

Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding. Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.

Why are metamorphic rocks usually harder and denser than their parent rocks?

Answers

Answer:

Explanation:

Metamorphic rocks are harder and denser than their parent rocks because they started off the same as their parent rocks but at some point were met with extreme heat and pressure. These conditions melted and compressed the parent rocks so much that it created metamorphic rock that was extremely hard and dense. This is why metamorphic rocks are usually found deep under the Earth's surface.

There are different types of rocks depending on their size, composition and location.

They are harder and denser than their parent rock because of tremendous radiation and temperature.

They are the rocks that are produced from the before developed rocks through the process of transformation.

They get modified due to the high heat and pressure found in the deepness of Earth.

The process of metamorphosis includes melting of the parent rock which later gets harder.

Therefore, metaphoric minerals are found deep inside the Earth.

Imagine that four genes on a single chromosome in a mutant phenotype of Drosophila cross over at half the normal rate as in the wild-type phenotype. How, if at all, would genetic maps of that chromosome differ between this mutant and the wild-type fly

Answers

We know that frequency of recombination is proportional with the distance between the genes on the chromosome. Therefore when the recombination rate is higher that means the distance between the genes on the chromosome is bigger. If the recombination rate is lower that means the genes are closer to each other on the chromosome. In this case the cross over rate is half the normal rate in the wild-type. That means that on the genetic map the distance between the two genes on the wild type will be twice bigger than the genes of the mutated Drosophila.

Seaweed to Bacteria
C. Bacteria to Seaweed to Fish to Seal
to Polar Bear
D. Seaweed to Bacteria to Seal to Fish
to Polar Bear

Answers

Answer:

C. Bacteria to Seaweed to Fish to Seal to Polar Bear

Explanation:

Every ecosystem consists of multiple organisms. These organisms feed on each other, forming a food chain. The energy within an ecosystem flows through the food chain.

Here, we're supposed to determine which food chain is the correct one. All organisms can be divided into producers and consumers. Producers are organisms that produce their own food, while consumers feed by consuming other organisms.

The only food chain that makes sense is shown in option C. I wouldn't say that bacteria belong to it as the seaweed is an example of a producer. It doesn't consume other organisms. But, fish feed on it, then seals eat the fish, and polar bears eat the seals. This is why we can safely say that option C is the correct one, despite bacteria being present there. Any other combination wouldn't work as, for example, bacteria (A) and seals (B) can't eat polar bears and the fish can't eat seals (D).

Which kind of of electrical charge is found on a hydrogen atom of a polar water molecule? A. A negative charge, because of a covalent bond with oxygen B. A negative charge, because of an ionic bond with oxygen C. A positive charge, because of an ionic bond with oxygen D. A positive charge, because of a covalent bond with oxygen

Answers

Answer:

D. A positive charge, because of a covalent bond with oxygen

Explanation:

A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

Los fosfolípidos se disponen formando una bicapa, dentro de la cual los grupos fosfatos (con mayor afinidad por el agua, es decir hidrofílicos) se orientan hacia el exterior celular y hacia el interior de la célula, mientras que las colas de ácidos grasos (hidrofóbicas, por lo que tiene mayor afinidad por sustancias no polares) se encuentran en la parte interna. Además, la membrana posee otro lípido: el colesterol, el cual tiene como principal función la regulación de la fluidez de la membrana.
