Answer:
Gene pairs segregate randomly and independently of each other.
Explanation:
Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.
For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.
Answer:
Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
Explanation:
Plant Root and Shoot System. Plants have two Organ Systems: the shoot system and the root system. Stems have many jobs, including supporting the plant; acting like the plant's plumbing system, conducting water and nutrients from the roots and food in the form of sugar (glucose) made in the leaves to other plant parts.
Asexual And Sexual is the correct answer
Answer:
The correct option is 3
Explanation:
An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.
The third option can be easily answered using the "requirements" above.
The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls
The aim would be to determine the effect of different types of grass on the movement of a ball
The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
