The standard unit of radiation related to biological hazards is known as the Roentgen.
Answer is membrane protein
Plasma membrane or cell membrane is made of lipoprotein (lipid and protein). The structure of the plasma membrane is based on the fluid mosaic model which gives basic description of the structure and behavior of membranes. The plasma membrane is a mosaic of phospholipids, cholesterol and proteins. Many proteins can move within the plasma membrane through membrane diffusion. The membrane proteins regulates the coming and going of substances into and out of the cell.
Answer:
the electrical impulses get sent through the conduction pathways which cause ventricles to contract and this allows heart to pump blood.
Explanation:
The electrical impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.
And it should be understood that, an electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). The electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood.
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
