Answer:
Gas exchange during respiration occurs primarily through diffusion. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs.
Explanation:
Answer:
On a simplified level, photosynthesis and cellular respiration are opposite reactions of each other. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
During asexual reproduction
The correct option is (d) The early solar system had large amounts of water; so, the oldest objects in the solar system should also be abundant in water.
The statement that answers the scientific questions in the form of scientific data that supports the claim is called a scientific claim. There is need for the justification of the claim. The scientific claim here is The early solar system had large amounts of water and the justification to the claim is water is found in all the primitive bodies like the comets and the asteroids and in many dwarf planets like ceres. There are many evidences that shows that there are abundant amount of water in our solar system.
The answer is

The interdependence
of body systems is essential because all systems work together to maintain
homeostasis. Homeostasis in body systems refers the regulation of internal
conditions keeping it stable and relatively constant. In humans this refers to
its ability to maintain stability in its internal environment while responding
to changes in external conditions. It serves as a sensor that detects changes
in the conditions that need to be regulated to meet the demands of the
condition and give the necessary feedback. Regulation of body temperature and
the balance between acidity and alkalinity are examples of homeostasis in the
human body.</span>
