Answer:
Organic compounds contain carbon and hydrogen (which may be replaced by other atoms).
The correct option is, B, that is, RADIAL SYMMETRY.
Symmetry refers to the balanced distribution of the duplicated body parts or shapes within the body of a living organism. There are different types of symmetry, we have bilateral, radial and asymmetrical symmetry.
Radial symmetry refers to the type of body plan in which the body parts are arranged around a central axis, that is, the body parts are arranged in a circle around an axis.<span />
Answer:1.Yellow color will be dominant and the ratio is Yellow to green allele is 3:1
2.A recessive test cross should be appropriate.The result will be all yellow colored pea plants.
Explanation:
Since Yy x Yy produces
1YY,2Yy and 1yy then it shows that YY and Yy are 3 yellow pea plants and 1yy green pea plant.
A recessive test cross should be used because a recessive genotype being homozygous can be noticed by its physical appearance
The answer to this question is separated
Answer: Water can dissolve salt
Explanation:
The polarity of water molecules enables water to dissolve many ionically bonded substances.
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions.
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.
The substance being dissolved is called the solute, and the substance doing the dissolving is called the solvent.
