What do hydrometers test?

rusak2 [61]

Hello.

The answer is: A. the buoyancy of water

hydrometer is an instrument used to measure the specific gravity of liquids; that is, the ratio of the density of the liquid to the density of water, Used for measuring the relative density of liquids based on the concept of buoyancy.

Both ancestral birds and ancestral mammals shared a common ancestor that was terrestrial. Today, penguins (which are birds) and

Talja [164]

Answer:

2

Explanation:

The bones in the forelimbs of penguins and seals are best described as analogous, while the flippers of penguins and seals are homologous.

Analogous structures are structures that are similar in different organisms, even though they are unrelated to each other. For instance, the wings of birds and the fins of a penguin or a fish.

Homologous structures are similar structures in related organisms. Both the penguins and the seals have flippers. Another example is the human arm and the wings of a bat. Both have similar structures internally, but while a human lifts items with their hands, the birds use theirs for flying.

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.
