Answer:

The discoveries made by earlier scientists led to the development of modern atomic theory. The modern atomic theory claims that each element is made up of atom of different kind. It explains that atoms are made up of sub-atomic particles.

Claim: Works from earlier scientists helped in the formulation of the atomic theory.

Evidences:

John Dalton brought forward the theory that all matter is made up of atoms which are spherical and can move.
J.J thomson discovered the electrons.
Robbert Millikaan measures the charge on an electron.
James Chadwick discovered the neutron.

Reasoning: All these evidences show that the discoveries of the earlier scientists led to the discovery of modern atomic theory.

rjkz [21]

The given statement that although cleft lip and cleft palate frequently occur together, cleft palate is repaired soon after birth and repair of cleft lip is deferred until the child is between 1 and 2 years old is false.

It is a birth defect because the development of mouth did not take properly inside the mother's womb. The surgery of this condition can be conducted within 3-6 months of birth.

C) No, because cutting mistakes could lead to incorrect cloning.

Explanation:

in molecular cloning, if you want to insert a specific gene of interest in to specific vector, the selection of enzyme and strategy before that is very important. The restriction enzyme should be selected which restrict at the desired location in the cloning sites. Any mistake in these selection or undesirable mutation mistakes can lead to in correct or unsuccessful cloning results.
