The inter-tropical convergence zone because it is a shifting zone between the tropics of cancer and capricorn were surface wind converge.
The inter tropical convergence zone is a belt of low pressure which circle the earth generally near the equator. The trade winds of the northern and southern hemisphere come together at this zone of inter tropical convergence.
The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:
-Certain genes could affect the metabolism of skin melanocytes.
-Other genes can determine the distribution of melanin in the thickness of the skin.
-Some genes could determine the relative amounts of each of the two possible types of melanin.
-Others may affect the production of certain hormones involved in the activity of melanocytes.
Answer:
a. The apparatus that was used to distinguish heavy DNA from the light ones were the centrifuge tubes. The samples of DNA gathered are placed in the centrifuge tubes comprising cesium chloride. The light and the heavy DNA get distinguished on the basis of density after performing high-speed centrifugation for the duration of two days.
b. At the time of the beginning of the study, the three prevailing models for the replication of DNA were conservative, semi-conservative, and dispersive. According to the conservative model, the original parent strands remained in combination post replication, and the daughter duplex is formed of newly produced DNA.
On the basis of the semi-conservative model, the two DNA duplexes formed at the time of replication exhibits one of the parental strands and one newly produced strand. While on the basis of dispersive model, the two new DNA duplexes comprise segments of parental and daughter strands.
c. The conservative model for the replication of DNA was ruled out definitively by performing density gradient experiments.
d. The dispersive model was discarded by using heat to denature the DNA duplex, and by comparing the densities of the single-stranded DNAs. If this model was accurate then the strands would have exhibited intermediate density.
