Answer:

Continental drift; Mid-ocean ridges

Explanation:

Hess expanded on Wegener’s theory of continental drift.

Continental drift was a theory that explained how continents shift position on Earth's surface i.e how it moved over geologic time relative to each other. This theory was developed in the early part of the 20th century, mostly by Alfred Wegener.

Hess described how hot magma would rise from under the crust at the Great Global Rift as the ocean crust spreads and cools over millions of years, it becomes denser and eventually sinks down into oceanic trenches, which explained how the once joined continents had separated into the seven that exist today .

Hess proposed the idea that mid-ocean ridges are places where crust is created.

Mrac [35]

When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression

Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.

If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.

However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.

alekssr [168]

Answer:

No, Hardy Weinberg Equilibrium is a theory that states the allele and genotype frequencies in a population will remain constant irrespective of the sexs.

Explanation:

Derivations from the HWE Hardy Weinberg Equilibrium assume that organisms are diploid, population size is infinite, and mating is random.

In all the equilibrium the four fundamental factors like the selection, mutation, random mating including interbreeding and small population size. So, if the number of heterozygotes is 34 then the significant level is 0.067.

So higher the significance level higher is the heterozygotes. In the absence of selection and genetic drift, all the frequencies within variables are constant. This principle was named by G, H Hardy.

Answer:

European nations used their Pacific Island colonies in various ways. Some islands were essentially plantations and were dedicated entirely to agricultural production on a large scale. Still other islands served as military bases, nuclear test sites, or trust territories.
