B. It provides information about why certain measurements are made in an experiment
From experience, to be able to have background research helps in the design of an experiment because it would tell you what is being measured in a experiment. Without the background information, my whole class got lost on what to do until my teacher told us what we had to measure and how we could measure the experiment.
Answer:
chromosomes.
Explanation:
Chromosomes occur as strands of long-chain protein molecules called DNA. Chromosomes are made up of two strands each called chromatid . The chromatids are joined at a point called centromere. During prophase, the chromosomes become tightly coiled and so appear shorter and thicker. Parts of chromosomes form functional units called genes which determine different activities of the cell. Genes are hereditary and can be transmitted from parent to off-spring.
Answer:
an average of 3 weeks (19-21 days)
Explanation:
Mendelian genetics one of the fundamental laws is The Law of Independent Assortment. The law states that parental traits are passed independently from parent to child. The recessive trait, vestigial Wings, occurs in an approximate phenotypic ratio of 1.3. In monohybrid Cross of heterozygous (Rr) parents the expected phenotypic ratio correlates with the given 1:3 result therefore l can conclude that the parents are both heterogeneous (Rr) for vestigial wings. Normal Wings-R, Vestigial Wings (Parent 1) Rr* Rr (Parent 2) R*R- RR- Normal Wings (Child 1) R*r Rr- Normal WIngs (Child 2) r * R - Rr- Normal Wings (Child 3) r*r- rr Vestigial Wings (Child 4) 1 Vestigial Wings: 3 Normal Wings
