Explanation:
As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Well the endoplasmic reticulum has both smooth and rough bodies. Smooth is the synthesis of fats and detoxifies harmful bodies. Mostly in the liver. And the rough mainly synthesize proteins which are basic components of life. Proteins are sent all over the body and are used for many functions. The golgi is used to package those proteins and send those proteins through the body. Mitochondria creates energy and is the power house of the cell. And the plasma membrane is like the gate keeper. Decides what can enter it exit the cell and prevents harmful things from coming in. Allows proteins to leave.
Answer: A
Explanation: there clearly isn’t no dinosaurs now so it can’t be b or c
The name is chemoreceptors; this is because they both respond to chemical in solution. A receptor is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some cellular/tissue response; e.g. a change in the electrical activity of a cell. Chemoreceptors are cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptors may monitor external stimuli, as in taste and olfaction, or internal stimuli, such as the concentrations of oxygen and carbon dioxide in the blood.
The Ordovician is best known for its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts (early vertebrates). A typical marine community consisted of these animals, plus red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods.
