Answer: My best guess would be B but i might be wrong that sounds most right to me. :)
Explanation:
I think that about half of all babies are able to walk independently by 12 month of age. It said that babies tend to take their first steps from the age of 9. Babies usually start to crawl before they can walk. This is because their arm are usually more effective. After crawling they learn to stand up with their feet first and later learn to walk while holding things. The next step after that is walking.
Not all babies walk at the same time. There those that learn before the other so there is no need to worry if your child does not walk by 12 months.
Answer:
A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.

Answer: All of the statements are true.
Explanation:
Purines are biologically synthesized as nucleotides and in particular as ribotides, that is, bases attached to ribose 5-phosphate. Adenine and guanine are both derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system.
Purine nucleotides can be synthesized in two distinct pathways. First, purines are synthesized de novo, starting with simple starting materials such as amino acids and bicarbonate. the purine bases are assembled already attached to the ribose ring. Alternatively, purine bases, released by the hydrolytic degradation of nucleic acids and nucleotides, can be salvaged and recycled. Purine salvage pathways are mostly noted for the energy that they save and the remarkable effects of their absence.
All statements are correct because the organization of purine synthetic enzymes involves multifunctional enzymes, reversible enzyme formations, through out the sequence there is maintenance of high local concentration and the ten steps requires only six enzymes.
