Meat is not a good source of protein because it does not provide the body with all the essential amino acids.
tankabanditka [31]

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

Answer:

The correct answer would be large NA

The resolution of a microscope is defined as its ability to distinguish two closely placed points as different entities.

The NA or numerical aperture of an objective is defined as the ability of a microscope to gather light.

NA determines the resolving power of the microscope that is, the higher the NA the higher will be the resolving power of the microscope.

Do you think that there should be a standard when participating medicine and science ?
9966 [12]
Honestly, this is supposed to be your opinion, but I will give you mine. I think there should by far be a quality standard, that they should always provide good quality things. It all just depends on what kind of standard they are talking about or what the question is referring to. If there are experiments going on, there should definitely be a certain standard of safety and ensure that the person would come out alive. I hope that this could help a bit, and I apologize if this was not the type of standard in which you were looking for. If you need further help, you can send a DM my way and I will respond when I get the chance. Have an amazing day!
