Answer:

the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Answer:

Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.

Sometimes genes, for no known reason, change their form in a process called spontaneous __________.

cupoosta [38]

Answer:

Mutation.

Explanation:

Mutation may be defined as the sudden heritable change in the DNA sequence of the organisms. Mutation can results in the change in the genotype and phenotype of the organisms.

Two main types of mutation are spontaneous mutation and induced mutation. Induced mutation occurs intentionally with the help of the mutagens. Spontaneous mutation is the natural mutation that occurs for the no known reason.

Thus, the answer is spontaneous mutation.

Choose the equation that represents an exponential function that passes through the point (2, 36).

Alla [95]

Since we were given only one point, we have to test each exponential function for the point $(2,36).$

Since exponential functions are of the form $y=n(a)^{kx}$ , The correct option is between option A and option C.

For option A,

$f(x)=4(3)^{x}$

On substitution, we have;

$36=4(3)^{2}$

$\Rightarrow 36=4\times 9$

$\Rightarrow 36=36$ .

Since the point satisfied the exponential function $f(x)=4(3)^{x}$ , the exponential function goes through it.

Hence the correct answer is option A.

No need to test for option C again.
