How does the nervous system and endocrine system work together to send messages through the human body? A) The nervous system uses electrical signals, while the endocrine system uses chemical messengers. B) The nervous system uses hormones, while the endocrine system uses neurotransmitters. C) The nervous system and the endocrine system are entirely separate and do not work together. D) The nervous system and the endocrine system both use electrical signals to transmit messages.

Answers

Answer:

The answer is A: The nervous system uses electrical signals, while the endocrine system uses chemical messengers

Explanation: Your body uses electrical signals to move muscles and all types of things like that. The reason you can move your fingers on demand is because of your brain sending electrical signals. Now for pain your body uses chemical signals. Your brain sends out chemical signals letting you know that you are in pain in that specific area.

Which reaction occurs most rapidly at standard conditions?H2(g) + I2(s) 2HI(g)
Cu(s) + S(s) CuS(s)
C6H12O6(s) + 6O2(g) 6CO2(g) + 6H2O(g)
5C2O42-(aq) + 2MnO4-(aq) + 16H+(aq) 10CO2(g) + 2Mn2+(aq) + 2H2O(l)
Ag+(aq) + I-(aq) AgI2(s)

Answers

I don't know of any way to determine the relative rates of reactions other than pretty much just guessing. Even with guessing, I can't decide between the last two. Both occur in solution and (if I recall correctly) both occur quite rapidly. I would guess that the last one, just a simple precipitation, would probably be the fastest.

(NOTE: You have the wrong equation on the last one. It should be Ag+(aq) + I-(aq) --> AgI(s) There is no subscript on the iodide ion in AgI.)

How are the alleles for sex-linked traits inherited? They are passed from the Y chromosome in parents to the X chromosome in offspring. They are passed from the X chromosome in parents to the XY chromosome in offspring. They are passed from parents to offspring on the X and Y chromosomes. They are passed from any chromosome in the parents to the X or Y chromosome in the offspring.

Answers

Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.

Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.

Thus, X-linked traits are passed from parents to offspring via the X chromosomes only. Since both males and females have X chromosomes, it means both genders can have X-linked traits.

Y-linked traits are passed from parents to offspring via the Y chromosomes only. Since only males have Y-chromosomes, it means that only the male gender can have Y-linked traits.

Answer:

they are passed from parent to offspring on the X and Y chromosomes
