Answer:

They can grow because the fibers in cotton attract and hold water while allowing some free space for air to penetrate. ... With these, seeds can grow almost in any medium provided that they have just enough water and oxygen.

Template DNA 5' GATTCAGAGA 3'

5' GAUUCAGAGA3' mRNA strand

codes of mRNA GAU, UCA, UAG

Explanation:

5' GATTCAGAGA 3' is the example of DNA strand having the sequence.

The DNA strand is leading strand and is in 5' to 3' direction

the complementary DNA strand is formed in 3'to 5' direction as the strand of 5' to 3' acts as a tempelate for complementary strand.

During replication which is semiconservative a new template is formed by adding the nucleotides to the growing strand.

DNA synthesis always takes place in 5' to 3' direction.

5' GATTCAGAGA 3'

3' CTAAGTCTCT 5' Complemntary strand

Transcription is a process in which DNA sequence is transcribed into mRNA which carries codes for amino acids.

The 5' to 3' strand is called sense strand

3' to 5' strand is called antisense strand. mRNA is transcribed from antisense strand and is a copy of sense strand.

so the transcribed DNA strand as mRNA will be shown as:

3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

GAU codes for = Aspartate

UCA codes for = serine

GAG code for = glutamate (when due to mutation GAA will become GAG)

A will not code as it is not in triplets.

Which type of population growth is shown in this graph? Population of Bacteria

Lesechka [4]

Answer:

Bacterial population shown in the graph is of Exponential type.

Explanation:

When the rate of population increases over time in proportion to the population size, it is known as exponential growth of population. Bacterial reproduction happens in an hour time span for many bacterial species by splitting itself in half.

This shows how the exponential growth occurs in bacteria. The amount of population gets increased with added organisms in generations of species.

The protoplasm and cytoplasm of a plant are interchangeable terms.TrueFalse

Svetllana [295]

No, they are not interchangeable because p<span>rotoplasm is the living content of a cell that is surrounded by a plasma membrane (cell membrane). Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macro-molecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. </span>

Assume you are growing a bacterial culture in a glucose medium. your lab partner adds more glucose in hopes of speeding up the e

timama [110]

Bacterial cells died because they plasmolyzed. when higher amount of glucose was added in the medium, the medium became hypertonic in comparison to plasma of the bacterial cells. As a result, water moves from the cells to medium by osmosis making the cells to shrink and lose their normal functioning which cause their death.
