contains many small spaces
Intro
Done
Answer:
strong, dense outer layer of a bone- compact bone
tissue in the hollow part of the bone- bone marrow
lightweight, inner layer of a bone that
contains many small spaces- spongy bone
Explanation:
Compact bone is also known as cortical bone and is a major property and source of skeletal frames in the body due to its strong, dense outer layer.
Bone marrow is the tissue in the hollow part of the bone. It is important as it helps in the production of blood cells
Spongy bone is also known as cancellous bone. It is the lightweight, inner layer of a bone that contains many small spaces which contains a high proportion of bone marrow.
Answer:
The nucleus.
This organelle is where most DNA or genetic material is found in cells.
B. carbon dioxide
C. oxygen
D. nitrogen
Answer:
B. carbon dioxide is the correct answer.
Explanation:
The greenhouse effect is caused by human activities like cutting the forest and fossil fuel burning, increase the level of carbon dioxide gas(greenhouse gases) and creates global warming.
When the fossil fuel is burned carbon combines with oxygen to form Carbon dioxide and it increases the concentration of greenhouse gases and give rise to global warming.
The Greenhouse gases Carbon dioxide traps the radiating heat from the Earth, this heat is absorbed in the form of infrared radiations and the radiation is emitted which warmer the lower atmosphere and Earth surface,this result in melting of ice sheets, glaciers and warming the ocean
Thus carbon dioxide greenhouse gases which creates global warming.
