Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
Answer
About 10% energy is converted to biomass from one trophic level to another trophic level.
Explanation
Food chain is composed of different trophic level which are classified on the basis of their mood of food obtain. These include
1. Producers (photosynthetic)
2. Primary consumers (herbivore)
3. secondary consumer (Carnivore)
4. Tertiary consumer (carnivore)
5.Quaternary consumer (Carnivore)
6. Decomposer
As larvae are hatched by insects which belong to second trophic level. About 90% of energy in food is lost at each trophic level. As move down the trophic level the number of organism also decreases in each trophic level. Therefore, energy transfer from one trophic level to another is like a pyramid.
Answer:
The <u><em>second </em></u>line of defense.
Explanation:
In our bodies the <em><u>second line of defense</u></em> includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.
Answer: directional selection, disruptive selection and stabilizing selection
Explanation:
Natural selection is when organisms adapt to the environment and pass down these adaptations to their offspring when they breed
Antheridia- is reproductive that produces MALE gametes. AND
Archegonia- is reproductive that produces LADIES gametes
