Answer:
Homeostasis
Explanation:
Homeostasis is the maintenance of a steady-state/condition in the body to ensure the optimal workings of the cells. Blood sugar level is one of the variables in the body that also has to be maintained through positive and negative feedback loops to maintain the desired level. Insulin is the hormone used for negative feedback (to reduce the blood sugar level when it goes higher than the normal level) and Glucagon is the hormone for positive feedback (to raise the blood sugar level when it goes below the normal levels).
B - exocytosis.
Think of like materials EXitig the cell via EXocytosis
the plants developed due to a lack of water and a need to preserve as much water as possible
The answer is algae.
Plankton includes a diverse group of organisms that live in the water, but are not capable of active swimming against the current. Therefore, since shark, squid and crab can swim and algae cannot, <span>among these groups </span>only algae can be a plankton.
Epithelial tissue is composed of the innervated and avascular layer of cells which are tightly packed. It forms the outermost layer of the body and protects the internal layers and organs.
This tissue can be classified into different categories based on the shape of its cell, and the total number of the layers.
The epithelial tissue with only one layers is known as the simple epithelial tissue.
The epithelial cells that are thin, flat, and scaly are known as the squamous cells.
While the cubodial cells are round or square in shape.
Hence, the given blanks can be filled with classified, simple, squamous, and square.
