The question is incomplete as it does not have the options which are:

A. More; more; gravitropism

B. More; less; phototropism

C. Less; more; gravitropism

D. Less; less; phototropism

Answer:

B. More; less; phototropism

Explanation:

Auxin is a hormone which is involved in the plant growth and the development by increasing the flexibility of the cell wall of the plant.

In the given question, the vertical root is rotated to the horizontal orientation which will be sensed by the roots and the roots will then redistribute the auxin in the roots.

The auxin will be transported to the lower areas but the growth of the root in the lower portion will be lowered as a result of which root will grow downward. This is considered a condition called positive gravitropism or negative phototropism.

Since the distribution of auxin is dependent on the presence or absence of light therefore this phenomenon will be referred to as the phototropism.

Thus, Option-B is correct.

A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Evgen [1.6K]

A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.

  • All living organisms, from bacteria to people, depend on amino acids for survival.
  • The same 20 types of amino acids are present in all living things.
  • Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
  • Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
  • The body is unable to produce essential amino acids. They must therefore originate from food.
  • Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

Explain the process of cross-pollination.
Anna007 [38]

Cross pollination is the transfer of pollen of different species to stigma of different species of plants.

Cross pollination results in healthy, viable and diverse plants.

Mendel observed that traits could either be dominant or recessive.

Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.

Explanation:

In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.

The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.

Mendel observed that traits are either dominant or recessive in general.  It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.

Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.

The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
