Answer:

The climate change may turn diseases spread in different areas of the Globe.

Explanation:

Climate change is producing the environment to evolve constantly. We may see rising temperatures across the Globe and with it some changes on rainfall as well. Those features will dramatically change the whole environment and could possibly turn habitats, that were in the past not associated with disease vector insects, into places like the northeastern from United States and thus, mosquistoes like the the vector of malaria can be a possible disease to hit developed countries.

Coin flipping simulates the events of mitosis and the production of sperm or eggs
a_sh-v [17]
Coin flipping simulates the events of mitosis and the production of sperm. This is because females carry XX chromosomes so all eggs will have a singular X chromosome. It is the sperm that determines the sex of the foetus: males have XY chromosomes and therefore sperm will carry either X or Y chromosomes (a 50/50 chance, just like flipping a coin)

Drag each tile to the correct box. Explain the process in which hormones secreted by the pancreas function with respect to incre
olga55 [171]

Answer:

The correct order is:

  1. High amount of glucose in the blood, sending signals toward the pancreas.  
  2. Synthesis of hormones by beta cells.
  3. Binding of hormones with receptors on the liver.
  4. Intake of glucose molecules from the blood by specific transporters.
  5. Release of hormones from the receptors  

Explanation:

  • The pancreas produces two hormones important for the regulation of blood glucose levels.
  • The two hormones, glucagon and insulin, increase and decrease the blood sugar respectively.
  • Insulin lowers the blood glucose by stimulating the body cells to increase the intake of glucose.
  • The brain senses high/low blood glucose, then, sends signals to the pancreas to initiate the synthesis of insulin or glucagon by the beta cells.
  • These hormones bind to receptors on body cells; on hepatic cells, in case of insulin.
  • The receptors initiate cellular signaling that facilitates intake or exit of glucose in or out of body cells.
