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.

Phototropism refers to the growth or movement of an organism (often a plant) in response to light stimulus. Negative phototropism occurs when an organsim grows away from specific chemicals.
- If a plant is grown in the absence of gravity, its roots will exhibit negative phototropism and auxin hormones will accumulate on the side away from the light source (Option C is correct).
- In this case, negative phototropism occurs in response to auxin hormones.
- On the other hand, positive phototropism occurs when a plant grows towards the light source.

Answer:
By the separation of the East African Rift, there were a difference among them.
Explanation:
Both Monkeys and Apes, have a common ancestor, in the late Oligocene, around 25 million years ago. But later, there were a branch in the East African Rift. This was a product of the crash of the Asian and Indian Continental plates, pushing the Tibetan Plateau. In an area that some day were flat, now some mountains, deep lakes and valleys appear. The new mountains, were a natural barrier for the sea wind, causing a dry weather and the lost of forest in this are. Since this is a topographical limits for some species, then the differentiation starts to Apes and Monkeys. One of the evidences is that the first hominids could develop the brain capacity, also the brain size.
