Answer:
Insertion
Explanation:
Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or exchange of a gene segment.
Insertion is a type of mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.
Here is an example of insertion mutation:
Base sequence: AUG GCC TGC
Product: met ala gln
Insertion:
Base sequence: AUG GCC C TG C
Product: met ala Leu
So we can see that the product protein is changed because of insertion.
Hope it helps!

Answer:
The correct answer is ''gravity.''
Explanation:
Tropisms are movements or changes in posture that a living being normally makes in response to a continuous environmental stimulus. Plants have hormones that respond to the gravitational impulse of our planet. Gravity deeply influences their growth and development (positive geotropism) and plants have been found to bend in response to gravity due to redistribution of the plant hormone auxin at the root tip, so that auxin is redistributed to the underside of a root that grows when it is rotated 90 degrees, the stems will still grow upward, away from the center of the Earth (negative geotropism), just as roots will always grow in the reverse direction (positive geotropism).
I would say that wind is the top agent of erosion that is assisted by gravity because gravity pulls down the sediments that the wind is eroding.
Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
