Answer:
I only know the first one It stores instructions for making other large molecules, called proteins. I think
Explanation:
Answer:
The threshold in biology is explained in terms of neuroscience or action potential that affects nervous system.
The threshold value is the value that identifies incoming signals that should be sufficient enough to generate an action potential. The potentials generated by the signals are additive, and reaches threshold depends on their amplitude and frequency.
An absolute threshold is defined as the minimum level of signals like light, touch or sound , detected by any organism and allows them to react.
While Difference threshold allow to detect difference between two different signals.
Sponges have specialized cells and an endoskeleton, but they lack tissues and body symmetry. ... They include jellyfish and corals, both of which have radial symmetry. All cnidarians have nematocysts, and many are bioluminescent. They may exist in medusa and/or polyp form.
When acid rain falls, aquatic animals get affected due to the spreading of acid rain which harms and destroy wildlife, it can reach to aluminum and then to soil, which basically destroys the ecosystem of the aquatic animals.
In order for a cell to differentiate into its specialized form and function, it need only manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.
