One difference is that plant cells have a cell wall while animal cells does not
Explanation:
Answer is Chloroplasts have their own DNA.
Chloroplasts and mitochondria are the two cell organelles which have their own DNA. This DNA is separate from the DNA which is found in the nucleus of the cell. The DNA of both chloroplast and mitochondria can replicates and both can undergoes division. The DNA of both organelles produce many proteins and enzymes required for their function.
The fourth way chemicals can enter the body is by injection. It can happen when a sharp device (like a needle) punctures the skin and injects a chemical (or virus) directly into the bloodstream, however it is unusual in most industries.
<h3>What in biology is the blood stream?</h3>
The phrase "bloodstream" refers to the flow of blood within an organism's body. In humans, the circulatory system, which is made up of a complicated network of arteries and veins, is where blood travels.
<h3>Where does the bloodstream reside?</h3>
The blood is gathered in veins and moves to the right atrium and right ventricle while being depleted of oxygen. The pulmonary circulation starts here: Low-oxygen blood is pumped from the right ventricle into the pulmonary artery, which divides into progressively smaller arteries and capillaries.

Answer: They divide it on eons.
Explanation:
They can see it from geologic strata and the fossil record. Major volcanic events altering the Earth's environment and causing extinctions may have occurred 10 times in the past 3 billion years. Different eons have different animal and plant life. (eg. trilobites)
Answer:
Explanation:
The Radiative Zone is located just beyond the sun's Inner Core, at a distance of 0.25 to 0.7 solar radii. Photon emission and capture by hydrogen and helium ions cause energy to be radiated in this zone.
