Answer:
Number 3
Explanation:
Dominant: 20, Recessive: 20
An allele is the alternative of a gene. On his case, these beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r).
As states earlier there are 20 red beans (20 dominant alleles) and 20 white beans (20 recessive beans) and each beach represent an allele.
The right option is; Hemiplegia
Hemiplegia is the paralysis that affects one half side of the body. Hemiplegia affects an arm and a leg on the same side and it can be either left or right side of the body. Hemiplegia is caused due to injury to the brain area that controls movements of body parts such as trunk, limbs, and face. Right hemiplegia is caused by injury to the right side of the brain while left hemiplegia is caused by injury to the left side of the brain. The level of hemiplegia of paralysis differs from an individual to another and it may change over time.
Answer:
XYY, spermatogenesis.
Explanation:
Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.
The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.
Thus, the correct answer is XYY and spermatogenesis
Answer:
D) products, such as cans and glass bottles
Explanation:
Minerals are naturally occurring inorganic solid substances that have more or less chemical composition and characteristic physical properties. Minerals are used for many purposes. Minerals (such as aluminum and boron) are used by industries to produce products such as cans and glass bottles. Minerals are also used in the construction/ building of houses and other buildings. Limestone, shale and gypsum are used to produce cement. Minerals such as diamond, pearls, and ruby are also used to make jewelry such as rings but an industrial society would MOST LIKELY use minerals to make products such as cans.
