A student formulated a hypothesis that cotton will grow larger bolls (node) if magnesium is added to added to the soil. The stud
ent has two experimental fields of cotton, one with mannesium and one without. Which data should be collected to support this hypothesis? (a) height of the cotton plants in both fields
(b) diameter of the cotton bolls in both fields
(c) length of the growing season in both fields
(d) color of the cotton bolls in both fields Why?
According to the hypothesis, the application of magnesium to cotton plants would support the growth of large cotton bolls. The field without magnesium would serve as control here. Cotton bolls from both the fields should be collected and their diameter should be measured.
If the diameter of the cotton bolls from the field with magnesium application is more than that of the cotton bolls from the control field with no magnesium, the hypothesis is correct. Therefore, measurement and comparison of the diameter of cotton bolls from the experimental and control field would allow the student to check the hypothesis.
Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium or, when it's along articulating surfaces, the synovial membrane
A VIRUS consist of RNA or DNA Genes and are therfore known as RNA Virus or DNA Virus
RNA genomes is seen in majority of Viruses. Bacteriophages possess double stranded DNA genomes whereas Plant viruses possess single stranded RNA genomes
Viral genomes are linear, as we see in the adenoviruses and circular as we see in the polyomaviruses
The shape of the genome is not determined by the type of nucleic acid present in it.
The genome is often divided into separate parts, in RNA and DNA viruses, and thus we called as segmented.
It's definitely not the woman, so I'd say it's B. As the trait is recessive, a person who doesn't have hemophilia itself is likely to be able to pass it on to there children.
