In order of importance, the world's four most important crop species are: CORN, WHEAT, RICE AND POTATOES. 
Corn is the most produced grain in the world and it is used as raw material for production of different types of food. Wheat is the leading source of vegetable protein in the world, it is usually grown in dry and cold climates.

Answer:

1.A

2.C

3.D

4.C

5.A

Explanation:

1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.

2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents

3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit

4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).

5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant

When you drink sea water, what type of solution do you expose your cells to?
Alex Ar [27]
The answer should be 1, hypertonic. 

Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules. 

Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration. 

So, the answer should be 1, hypertonic. 

In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!

A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
