The nervous and endocrine systems both use chemical messengers to communicate with target cells and maintain homeostasis. However, the nervous system's effects are immediate and short-lasting, while the endocrine system's effects are slower and longer-lasting.
Explanation:The nervous system and the endocrine system share a common role in maintaining the body’s homeostasis. Both use chemical messengers to communicate with target cells. In the nervous system, nerve cells or neurons produce neurotransmitters, which are released at the synapse to communicate with target cells. The endocrine system, on the other hand, uses hormones, which are produced by various glands and sent into the bloodstream to reach target cells throughout the body. However, there is a difference in the speed and duration of action. The effects of the nervous system are usually short-lasting and immediate, while endocrine system responses are slower and tend to have prolonged effects.

Which choice describes dna after replication has taken place? two molecules, each with one original and one new strand one molecule with two original strands and one molecule with two new strands two molecules, each with two new strands two molecules, each with two old strands?
The answer choice which describes deoxyribonucleic acid (DNA) after replication has taken place is: A. two molecules, each with one original and one new strand.
DNA replication can be defined as a biological process through which two (2) identical replicas of deoxyribonucleic acid (DNA) molecules are produced from an original deoxyribonucleic acid (DNA) molecule, especially during cellular division.
This ultimately implies that, DNA replication involves the duplication of a double-stranded DNA to produce two (2) identical deoxyribonucleic acid (DNA) molecules i.e one (1) original and one (1) new strand.
In conclusion, two deoxyribonucleic acid (DNA) molecules, each with one original and one new strand are produced after DNA replication has taken place.

Answers
1. Lead was once widely used in the United States as a gasoline additive but it was banned due to health risk.
2. Radon is a radioactive gaseous decay product of uranium that is found in rocks, soil and water.
3. Radon is a leading cause of lung cancer in the United States because the by-product of this can get trapped in the lungs.
4. Mercury poses a health risk to humans who eat large quantities of marine fish such a tuna and swordfish.
