The right answer is Watson and Crick.

The famous science journal "Nature" published an article of two pages, accompanied by one figure, titled "A Structure for Deoxyribose Nucleic Acid". Its authors are James Dewey Watson (24) and Francis Crick (36).

They synthesized the work of their scientific colleagues and were able to explain with a remarkable art of deduction how the DNA molecule contained in the cells of all living beings was duplicated.

How many times larger is the number of hydrogen atoms than oxygen atoms in a molecule of water, H2O? ______ b. Is this number th
garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.

How are long term and short term environmental changes similar? and how are they different?
netineya [11]

Answer:

Explanation:

Environmental changes occurs from time to time, we have the short term changes that do not last for a very long time and the long term changes that last for a while. Accumulate of short term changes can extend to long term as some of the long term effects are as a results of short term changes in the environment.

Short term environment changes can be favourable to some organism and adversely affect others. Raining season causes increase in growth and development of most plant species but a long period of drought and dryness makes its hard for some plant to strive while some plants can strive well in long period of drought. This makes the two changes different, the both have individual effects on plants response.

daser333 [38]

Answer:

The answer is D. Synthesizing DNA.

Explanation:

The synthesis (S) phase of the cell cycle is of critical importance to precisely replicating the genomic information encoded in the nucleus of the cell.

The major work of the S phase of the cell cycle is replicating the entire complement of DNA. To do this, the cell activates pre-replication complexes to make replication origins. These are simply areas of the DNA where replication will begin.
