Answer:
<em>Respiration and photosynthesis. </em>
Explanation:
<em>Respiration provides the cell with oxygen while photosynthesis provides it with carbon dioxide. Both functions release what is needed for the other. Therefore, these functions interact.</em>
The cost of the electricity if 42000 kWh of electricity is used is ; $1680
<h3>Determine the cost of electricity </h3>
<u>Given that ;</u>
value of electricity used = 42000 kWh
cost rate of electricity = $0.04/kWh
Final step : Determine the total cost of electricty used
unit cost = $0.04/kWh
Totals cost = unit cost * value of electricity used
= 0.04 * 42000 = $1680
Hence we can conclude that The cost of the electricity if 42000 kWh of electricity is used is ; $1680.

The statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes (option C).
<h3>What is the plasma membrane?</h3>
Plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semi-permeability of the plasma membrane means it allows some molecules through but blocks other substances.
The plasma membrane is the cellular structure that protects and encompasses the cell's content.
All living organisms possess the plasma membrane, which is also called cell membrane.
Therefore, the statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes.

Answer:
Explanation:
Compact bone aka cortical bone is a dense, solid and rigid in which bony matrix with ground org. Substances and salts densely filled and leave tiny spaces known as lacunae. These spaces contain osteocytes also called as bone cells. Inside of these osteons there is a central canal which supplies blood vessels and nerves within bone. These vessels provide blood to the spongy bone and living cells housed within compact bones.
Structure of Compact bone: Basic unit of Compact bone is called osteon also known as haversian system. Each osteon consist of four parts.
1. Haversian canal which consists blood vessels and nerves acts as a site of hematopoiesis which is one of the functions of Compact bone.
2.lamellae are concentric rings of strong matrix consisting Calcium and phosphorus. this gives the bone its strength and hardness to bear body weight.
3.Lacunae contains osteocytes.
4.Canaliculi links osteocytes and provide route for nutrients to reach osteocytes.
