Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.
Answer: 4
Explanation: There are 4 valence electrons in group 14, the Carbon group.
Answer:
a) Genes b and c are farthest apart.
Explanation:
Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment which is then incorporated into the chromosome or plasmid of recipient bacterial cell.
Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.
The following goal the U. S. Integrated Ocean Observing System (IOOS) is not intended to address is to promote ocean ownership.
<h3>What is the Integrated Ocean Observing System?</h3>
The United States' Integrated Ocean Observing System, is a network of people and technology.
It collaborates to collect and transmit data on our coastal waters, Great Lakes, and seas.
Some of its work is gathering data in the ocean, while others are on land or in space.
Thus, the correct option is C, which promotes ocean ownership.
