Answer:
2 (if you are just talking about Mitosis)
Explanation:
In Mitosis (the reproduction of body cells) there are two diploid (and identical) daughter cells
In Meiosis (the reproduction of gametes) there are four haploid (but non-identical) gametes (or reproductive cells)
I am pretty sure that you are talking about Mitosis but I wanted to add in Meiosis just for kicks.
The type of immunity that provides lifetime immunity for the body against a specific pathogen is called acquired immunity. It is also referred to as adaptive or specific immunity.
Acquired immunity is not present at birth. it is learned. As a person's immune system encounters foreign substances (antigens) the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its uniqueness lies in its ability to learn, adapt and remember.
Acquired immunity takes time to develop after first exposure to a new antigen. However afterward, the antigen is remembered, and subsequent responses to that antigen are quicker and more effective than those that occurred after first exposure. Memory of a particular antigen is kept by the B and T lymphocytes.
Answer:
Proteins reflect DNA sequences, so scientists study proteins to look for genetic similarities and differences in organisms.
Explanation:
lymphocytes are specialized T cell ,B cell, and natural killer cell .
these cells are distinguished from other lymphocytes by a protein on their surface known as the B cell receptor .these protein is specialized to recognize and attach to specific antigens.

1. Answer is "it provides all the elements for lipids".
The elements of glucose are carbon, hydrogen and oxygen. Hence, if the molecule glucose were broken down, those elements are released.
The elements of lipids are same as glucose. But sometimes lipids contain sulfur and phosphorous.
In proteins there is nitrogen as element other than carbon, hydrogen and oxygen.
Nucleic acids also have carbon, hydrogen, oxygen, nitrogen and phosphorus as elements.
Hence, glucose molecule cannot provide all the elements for proteins and nucleic acids but can provide elements for most of lipids.
2. Answer is “NO”.
The four types of macromolecules are carbohydrates, lipids, proteins and nucleic acids. Elements of those macromolecules are as follows.
Carbohydrates - carbon, hydrogen, and oxygen
Lipids - carbon, hydrogen, oxygen sometimes nitrogen and phosphorus.
Proteins - carbon, hydrogen, oxygen and nitrogen sometimes sulfur and selenium.
Nucleic acids - carbon, hydrogen, oxygen, nitrogen and phosphorus.
Sugars are also type of carbohydrates. Hence, sugars can provide only carbon, hydrogen, and oxygen as the elements. Therefore, sugars cannot provide all the elements that needed to make four types of macromolecules. But sugars can provide elements to make carbohydrates and most of lipids.
