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.
The food in the protein group and dairy group are high in saturated fats and cholesterol, it raise LDL in blood.
<h3>
What is cholesterol?</h3>
Cholesterol is a waxy like substance synthesized from two sources such as liver and from animals like meat, poultry, diary product.
There are two types of cholesterol, one is bad called LDL cholesterol and second one is good called as HDL.
LDL narrow down the arteries by depositing fats in it, the condition known as atherosclerosis which leads to increase in risk for heart attack, stroke and peripheral artery disease.
On the other hand, HDL protect against heart attack and stroke
Third component called triglycerides are the common type of fat act as a reservoir of excess energy.
Hence, LDL is the correct answer.

Answer:
A.) a negative charge that exist because of a covalant bond with Hydrogen
Explanation:
Polar covalant bonds have a negative charge in H2O there is 2 Hydrogen and 1 Oxygen
Biodynamics advocates natural, chemical-free, integrated practices to promote regenerative and self-sustaining agriculture, which appears to be a good thing.
However, woven throughout it is a great deal of mysticism and spirituality, involving ideas about 'life forces' and 'cosmic energies,' which were a hallmark of Steiner's theories and are far from scientific.
Biodynamics has been referred to as "pseudoscience" and even a "belief system" on several occasions, and while it has many pragmatic and level-headed practitioners, it also has a very wacky fringe.
A recent piece on the site 'Word on the Grapevine' sparked the newest round of controversy, with the author, Joshua Dunning, delving into the more esoteric aspects of biodynamics.
