Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
Explanation: Hope those are the only answers you needed. I just saw the stars next to them and figure those were the only ones you needed.
Answer:
Plants
Explanation:
Fungi have neither chlorophyll or chloroplasts. They feed on already manufactured food. They parasitize the plants because they have chlorophyll and make their own food. The fungi send haustoria to the roots of the plants where they obtain manufactured food.
Answer:
The Geographic barrier would have led to speciation in the finches which started from the founder effect where the finches were brought to other areas of the Galapagos. They were separated geographically so they could not mate with each other. Over time, evolution occurs through natural selection and genetic drift. This leads to the population being so different so they have reproductive barriers and can no longer interbreed. They become different species.

Hope this helps you understand better.
Answer:
Bacteria have cytoplasm and ribosomes which are common with the cells of other living organisms.
Explanation:
Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
