The answer is DNA ends. These ends often overhangs and anneal with another DNA end, forming a new base form. These ends will anneal with the use of hydrogen bonding which can help stabilize the ends. However, certain prerequisites must be followed to maintain the bond.

Answer:

The unbonded terminals of the DNA are known as sticky ends. They are called sticky as they exhibit complementary bases. The generally used restriction enzymes cleave the two complementary strands of DNA at distinct locations, producing sticky ends or overhangs.

These sticky ends permit for perfect base pairing and it takes place due to hydrogen bonding. These sticky ends permit one to insert DNA. These sticky ends play an essential role in molecular cloning as they make sure that the fragment of DNA is administered into the plasmid in an accurate direction.

19. If a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified?

Illusion [34]

<u>ANSWER:</u>

The correct option is B- Qualitative.

<u>EXPLANATION:</u>

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.

Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.

Select ALL the correct answers.A forest was cleared to build a road. Which two would be the most likely effects on the ecosystem

Kryger [21]

Answer:

Some species will develop adaptations to survive in the deforested land.

Some populations will migrate out of the deforested area.

Explanation:

The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.

Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

I hope this helps! :)

You are given two true-breeding groups of rabbits. The first group has floppy ears and white coat color. The second group has st

malfutka [58]

Answer:

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct
