<span>Each type of organic molecule has its own specific type of functional group. Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.</span>
It’s essential for the creation of DNA, cell membranes, and for bone formation in humans. It is also vital for food production.
The answer for this is B. Gravity has nothing to do with weight
Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring
Explanation:
Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.
The answer is;
Biosphere > Biome > Ecosystem > Community > Population
> Organism > Organ System >
Organ > Tissue > Cell > Organelle > Molecule > Atom.
This is a clear representation of the complexity of life on
earth. Over the course of evolution, abiotic elements developed into biotic
elements then to unicellular organism and finally to complex multicultural organisms.
