Explanation:
they help transport some substances through the membrane.
Answer:
synarthroses, amphiarthroses, diarthroses
Explanation:
The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses.
Photosynthesis and cellular respiration basically are dependent on one another. Photosynthesis produces a product of glucose, and oxygen as a byproduct. Cellular respiration uses both glucose and oxygen to produce carbon dioxide and water which are needed for photosynthesis to occur. Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival.
Answer:
Organism having the suitable traits appears more in the population.
Explanation:
Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.
Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.
So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
