Which end of the water molecule attracts most of the electrons and acts negative?

Answers

Answer 1

Answer: A water molecule is a polar molecule because ot the shape of its molecule. One side of the water molecule is positively charged while the other is negatively charged. The oxygen and the hydrogen atom in water shared electrons by covalent bonding, the oxygen atom has a slight negative charge and attract most of the electron to itself.

Which is a function of the central nervous system? A. pumping blood through the body B. controlling coordination in the body C. fighting bacteria that enter the body D. breaking down carbohydrates in the body

Answers

Answer: B. controlling coordination in the body.

Explanation:

The central nervous system consists of the brain and the spinal cord.
The central nervous system generates messages in the form of electrical impulses that are carried to the glands and muscles located in the body with the help of the motor neurons.
The motor neurons signal these glands and muscles to perform the required function and thus, the central nervous system helps to coordinate the body.

the answer is the second choice B.

Acetylcholinesterase is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine. Which of the following explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine?It would require a level of activation energy too high for acetylcholinesterase to react with other neurotransmitters.
      Binding with an alternate neurotransmitter would inhibit the reaction of the enzyme with acetylcholine.
      Reacting with another neurotransmitter would halt the production of the enzyme and raise the overall activation energy.
      Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered.

I think it might be the last one

Answers

"Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered" definitely best explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine. You were right. Good job. :)

What is meiosis?

Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce gametes (eggs and sperm). It involves two rounds of cell division, resulting in four daughter cells with half the number of chromosomes as the parent cell. Meiosis is important for maintaining the correct number of chromosomes in a species, as well as creating genetic diversity by mixing up the genetic information from the parents. It is a complex process that involves a series of phases including prophase I, metaphase I, anaphase I, telophase I, and then prophase II, metaphase II, anaphase II, and telophase II. During meiosis, homologous chromosomes pair up and exchange genetic information through a process called recombination, and then separate during the first division. The second division separates the sister chromatids, resulting in four haploid cells that are genetically distinct from each other and from the parent cell.

A. Interphase

B. Prophase I

C. Metaphase I

E. Telophase I

F. Prophase II

G. Metaphase II
