Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>
<u></u>
- The process by which an embryo transforms into a fetus is known as embryogenesis.
- The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
- Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
- The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
- An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.

Photosynthesis results in increased biomass for a plant. I<span>n photosynthesis, carbon dioxide and water
yield glucose and oxygen. So, the carbon dioxide and water are taken in and are create a glucose. Glucose can be transformed into organic molecules, such as starch, which will increase biomass.</span>
