In which of the following circumstances may animal work begin before receipt of IACUC approval? A. It is a continuing study awaiting three year renewal and for which the renewal protocol has been submitted to the IACUC.
B. It is a small pilot study on non-AWAR species.
C. It is a teaching activity that uses students' personally owned dogs and cats.
D. There are no circumstances in which animal work may begin before IACUC approval.

Answers

Answer 1

Answer:

Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)

Explanation:

The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.

Salts are covalently bonded.
The atoms in a molecule of water (H2O) are bonded together with ionic bonds.

Answers

The true statement of chemical bonds is covalent bonds share electrons between two atoms.

A covalent bond is a type of interaction that involves one or more pairs of electrons (e-) being shared between two atoms.

In a covalent bond, shared electrons are jointly attracted by both atomic nuclei.

A double covalent bond occurs when four electrons are shared between two atoms, whereas a triple covalent bond involves the sharing of six electrons.

An ionic bond is when one atom gives its electron to another atom, e.g., during the formation of sodium fluoride.

In conclusion, covalent bonds share electrons between two atoms.

What is the layer of myelin that surrounds an axon called?Group of answer choices

1. Node of Ranvier
2. Perichondrium
3. Perimysium
4. Myelin sheath
5. Periosteum

Answers

The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.

I think the answer is Nodes of Ranvier but I’m not sure. I hope this helped <3
