Answer:
grams
Explanation:
Given -
Half life of the silicon-32
years
Half life means the time period required by a radioactive element to reduce its mass by half.
Radioactive decay formula is

Where
A represents the amount of radioactive element after time t years
represents the initial amount of radioactive element
time of decay
half-life of the substance
Substituting the given values in above equation, we get -

grams
Explanation:
For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
both immigration and births add individuals to a population.
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.
