Explanation:
Cells through out the body develop and perform different functions.Different types of cells constitute to form tissues,and different tissues constitute to form an organ and different organs constitute form an organ system and different systems perform specific functions.The organ systems such as the digestive,circulatory,excretory,nervous,Respiratory,lymphatic system and reproductive system These systems are complex by the action of enzymes these systems are carried out.Without the enzymatic action the functions of a system cannot carry out.
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious.
Yes all information about DNA above is right , DNA stores<span> biological </span>information<span> in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.</span>Dna store information which is dependent on genetic code , which dependent on the genetic code. The code which define relation between the sequence of bases in DNA (or its mRNA transcript) .Every cell in the human body carries a bundle of DNA in its
nucleus — nearly 30,000 genes, and the chunk fromdna become proteins.. Each of the 46 chromosomes in a human
cell’s nucleus bears thousands of genes.
Answer is 12 billion kilometers
That is what quizlet says
Answer:
Harry will take 21 seconds
Explanation:
Speed = distance covered / time taken
Harry covers 12 miles in 6 minutes so,
the speed of Harry will be 12/6 = 2 miles per minute.
Therefore, if he covers 0.7 miles then time taken by him will be,
Time taken = distance covered / speed
= 0.7 / 2
= 0.35 minutes
= 0.35 x 60 seconds
= 21 seconds
I hope this helps :)
