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.

D. is the answer BTW this should be on chemistry topic not biology
I would say B but do you have any cladogram to read it, or you are supposed to know it?
B is probably correct because green algae are most primitive group of plants.
Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.
Answer:
All cells all the time.
Explanation:
Photosynthesis is the process of the formation of organic nutrients, glucose in the presence of sunlight by fixing CO2. Cellular respiration is the oxidation of nutrients. The process forms ATP which in turn serve as energy currency for living cells.
Plant cells perform cellular respiration to obtain the energy stored in the chemical bonds of glucose. The energy obtained by cellular respiration is used to perform the vital functions by cells. Therefore, irrespective of photosynthesis, cellular respiration occurs in all the cells of the plants all the time to fulfill the energy requirement for growth and development.
