C. The snails use about 10% of the plant's energy to carry out life
processes.
Explanation:
The tonsils located at the base of the tongue are the lingual tonsils.
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.
b. macrophages
Macrophage cell use acid to kill bacteria and fight infection in the human body but it can also replicate the bacteria so it kills itself off. So duplicates beforehand and attacks the bacteria before it spreads.
Answer:
1. Observation
2. Question
3. Hypothesis
4. observation
5. prediction or test
Explanation:
1. A question is being asked when something is being enquired about and generally consists of words like who, what, where, why, when etc with a question mark. Hence the below given statement is a question
Where is the whale meat being solid in Japanese markets coming from?
2. Observation is an interpretation made after viewing something for a certain period of time with concentration. Hence below given statement is an observation –
The availability of whale meat in Japanese markets exceds that expected from the reported legal captures of whales
Whales are being harvested illegally and their meat sold in markets in Japan
3. Hypothesis is an “if” and “then” scenario, in which a fact is rejected when there are not enough causes to support it.
If whale-s are being illegally harvested, reported whale captures will be far lower than the number of captures predicted by genetic analyses of whale meat in markets
4. prediction, or test1
When something is being experimented on or with to reach a conclusion. Hence the below given option is a prediction or test
Scientists subject whale meat to genetic analysis to determine its likely capture location and to extimate whale captures at that locationDrag each statement under the step in the scientific method that it demonstrates.
