Answer:
B
Explanation:
Cancer is essentially a disease of mitosis - the normal 'checkpoints' regulating mitosis are ignored or overridden by the cancer cell.
The outer cells of a blatocyst become the <u>placenta</u>, an organ that offers protection and nourishment.
Placenta, aka afterbirth, is an organ found in a female body that forms around the baby in order to protect and feed it. It provides nourishment for the fetus, keeps it warm, eliminates any infections that may occur, and overall protects the developing baby.
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
We can use the formula D=m/v to determine the density of the ring.
With that, the correct answer would be A. 2 g/ml.

Photosynthesis
Photosynthesis is a process where plants and other organisms convert light energy from sunlight into chemical energy which is subsequently released as fuel to the organism’s activities. Furthermore, is a process where green plants convert water, carbon dioxide and certain organic salts into carbohydrates. Thus, carbon dioxide is usually absorbed by the producers (Plants or other organisms) to make glucose during the process of photosynthesis
