Energy conversion within a plant cell would be limited most severely by removal of the cell's - A mitochondria B chloroplasts C ribosomes D endoplasmic reticulum​

Answers

Answer:

The answer is Mitochondria. I took the test and that's the correct answer.

Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.

What is mitochondria?

Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.

The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.

Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.

explain how and why an earthquake occurs in thorough detail. You should also be identifying the four labels below within your explanation. A good answer would be longer than a paragraph (but < 3)

Answers

Answer:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase

Answers

Answer:

12 chromatids.

Explanation:

If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning

Answers

Answer:

The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)

Explanation:

Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.

Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease  common with ketoacidosis is Diabetes.

which term names part of the peripheral nerves system A spinal cord B brain C sensors​

Answers

Answer:

[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]

Explanation:

There are two divisions of the nervous system: the central and peripheral.

The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.

The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).

So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors

What statement best describes symbiotic relationships?
O Different species live in close associations in an ecosystem.
Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.

Answers

It’s the first answer

The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.

What is the symbiotic relationship?

Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.

For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.

In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.

Thus, the correct option is A. Different species live in close associations in an ecosystem.
