Answer: The correct answer is- Observation.

Hypotheses is a statement that is hypothetical and can be proved wrong or right with the help of various experiments or observation.

Thories are explanatios of some important feature of nature that are established by collecting facts and observations over time.

Laws describe principles that corresponds to system of rules and regulations that are developed by experimental evidences and observations.

Thus, Observation is the right answer.

dangina [55]

I'll say that it is +1 since hydrogen is desperate to lose an electron to fulfill the octave rule (that the molecules want to gain 8 electrons and if they can't do it, they want to lose all their electron). Electron is - so if it lose a electron, it becomes +.
Hopefully this helps.
PS. I'm not certain of my answer but it is logical.

Chromosomes contain __________. Chromosomes contain __________. one type of macromolecule: nucleic acid no macromolecules, just

vovikov84 [41]

Answer: two types of macromolecules: nucleic acid and protein

Explanation:

Chromosomes particularly eukaryotic chromosomes are made up of nucleic acids in particular DNA (deoxyribonucleic acid) and some proteins which include histone proteins and non histone protein that helps in the packaging of an almost 2m DNA into a very tiny 0.6microm nucleus. The histone protein includes H2A, H2B, H3, H4 which forms an octamer around which the DNA is wrapped (structure of a nucleosome) and linker histone H1 joined to a linker DNA that links two nucleosomes.

Deletion of a DNA base from a gene affects an organism by—

sergiy2304 [10]

Answer:

Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.

Explanation:

A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:

Transcription of the mRNA, which will have the sequence of altered bases.
During translation, the mRNA codons will encode at least one different amino acid.
The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.

In summary, the deletion of a base in the DNA will affect the protein to be synthesized by changing the amino acid sequence of its structure.

The other options are not possible, because the deletion of a base in the DNA of a gene

Does not influence the number of chromosomes that the gametes will have.

It does not produce long chains in the chromosomes.

It does not affect the ribose structure of the nucleic acids.
