They are similar to blood vessels that are found in the cardiovascular system, but they carry lymph instead of blood.
Answer:
2 unit
Explanation:
According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.
Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.
that is 2000→200→20→2
note: only 10% of the total biomass is received by the next trophic level.
therefore tertiary consumers will receive 2 units of biomass.
Answer:
Independent variable: Adding/not adding soil.
Dependent variables: Does the plant grow? Amount of leaves, plant length.
Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.
Explanation:
Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.
Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.
Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.
Answer:
The level of metabolism in cells is affected by between multiple signaling pathways. These signals are integrated in the cytoplasm, and their net strength determines how much glucose to use, how much glucose to store, and how much protein to make.
True
Explanation:
Reasons why metabolism in cells is affected by multiple signaling pathways is as a result of energy consumed during the process of metabolism as it requires lots of energy for protein synthesizing, glucose storage among others.
