What’s Newton’s first law
Klio2033 [76]
Newton’s first law had to do with inertia, which is a property that explains that something in motion will continue in motion unless stopped by a force of some sort.

“An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”

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.

Explain why it is an advantage for plants to store carbohydrates as starch rather than as sugars​
Darina [25.2K]

Answer:

More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Explanation:

When plants have a period of dormancy to survive, they store their food as starch. They store enough of this energy so as to be able to restart with and to be able to maintain metabolism for the entire period of dormancy.

In addition, we know that starch is not water soluble, hence, lacks the ability to pull water into storage cells or cause irregularity in water balance. More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.

Glucose is not directly transported by plants to storage. Rather, in a plant stem, the form of carbohydrate being transported is sucrose and this is because it is a non-reducing and does not react with oxygen during transport in the stem to specialized storage plastids.
