Answers

Answer 1
Answer:

Answer:

The correct answer is option A, that is, nerves.

Explanation:

The nerves are also known as neurons that make up the nervous system. The nerves are considered as the unique cells, which conduct messages from one section of the body to another, as minute electrical signals. These messages are also called nerve impulses. There are three distinct kinds of neurons known, and each one exhibit a somewhat different function. These are relay neurons, sensory neurons, and motor neurons.
Answer 2
Answer: A. Nerves, it's literally the only one that makes sense

What is the isotope and isotopic notation symbol for Z = 29, A = 65?

Answers

Isotopes are atoms with the same number or protons and electrons but different numbers of neutrons. 
Here, we got Z = 29 so the charge of the nucleus is 29, and A is the atomic mass. 
Since the atom number (Z) is 29, so i guess the isotope is the Copper. 
Isotopic notation: Cu_(29)^(65)

Hope this Helps :)

Final answer:

The isotope with atomic number Z = 29 and atomic mass A = 65 is for Copper and its isotopic notation is 65Cu.

Explanation:

The isotope with atomic number Z = 29 and atomic mass A = 65 is for the element Copper (Cu). To write this in isotopic notation, you represent it as 65Cu. Here, the atomic number Z (number of protons) is represented by Cu and the mass number A (number of protons + neutrons) is represented by the superscript number 65. Thus, the isotope notation symbol for this is is 65Cu.

All chemical reactions use reactants in a specific proportion or stoichiometry to form products. The __________ reactant regulates the amount of products produced. A) excess B) limiting C) proportional D) stoichiometric

Answers

The correct answer is B) Limiting.


Hope this helped!

Answer:

B: Limiting

Explanation:

The limiting reactant regulates the amount of products produced, because you have the least amount of the limiting reactant.
