Answer:
1) The statement is false
2) Option A) deoxyribose, phosphate, and a nitrogenous base
Explanation:
1) In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative
2) DNA consists of several repeating units of polydeoxynucleotides where each is made up of a nitrogenous base (Adenine, thymine, cytosine or guanine) linked to
deoxyribose sugar by an N-glycosidic linkage, and then the sugar linked to a phosphate group by phosphoester bond.
I believe it’s build drainage systems
Answer:
The correct answer is- digestion, absorption, transport, elimination
Explanation:
The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.
In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.
This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.
Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.
Therefore the correct order are: digestion → absorption→ transport→ elimination.
Answer: diastema
Explanation:
Diastema is condition in which a gap develops in between the two teeth. The spaces or gaps develop in the upper front teeth. The space or gap may appear between the biting teeth (canines or incisors) and in between the grinding teeth (molars or premolars). This occurs when there is unequal relationship develop between the size of jaw and teeth. The space can be too large that it can accommodate the parts of lower canine.
According to the above description, the condition can be considered as diastema.
Answer:
The plant cells with mutated (nonfunctional) aquaporins support the alternative hypothesis stated by different groups.
Explanation:
Aquaporins are proteins which are responsible for the transportation of water molecules across the semipermeable membrane of the cell. The main function of Aquaporins is to allow water molecules into the cell and block the passage for the ion molecules. Water can also pass through cell membrane through simple diffusion that support the alternative hypothesis.
