Answer:
B. diaphragm
Explanation:
this structure flutters and causes the chest cavity to largen
The answer would be lipids, they are a type of biomolecule and a nucle is an organelle
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Answer:
Yes global temperature could rise due to lead (Pb)
Explanation:
From the recently study as "Potential Effects of Global Warming on Atmospheric Lead Contamination in the Mountains" it is clear that lead (Pb) is contaminating water and that water is being used by plants which also a cause of seasonal fluctuations. Due to these fluctuations winters and summers are changing although this is a very small change. But this is resulting in melting ice from glaciers.
