1. The observation of Wegener's theory was that the identical fossils were found on continents that were far apart. Alfred Wegener's  refined theory of continental draft tried to pinpoint pieces of proof that the continents were previously combined into a sole continent he called Pangaea. Wegener's theory hypothesized that it was the continents that were able to shift through the rock of the seafloor to their existing locations.

2. When tectonic plates moves, the feature that is been seen is new ocean ridges and seafloor. Although when these plates collides, earthquake occurs. Tectonic plates are the pieces that explains the movement of the earth. The upper most layer of the earth is made up of these plates. They are categorized in major plates, minor plates and micro plates.

3. A convection cell is cold, dense material sinks while hot, less dense material rises. It is basically a happening that transpires when density variations occur within a body of liquid or gas. These density differences effect in increasing and/or decreasing of flows, and these are the key components of a convection cell.

In humans, brown eyes are dominant to blue eyes. If a blue-eyed man has children with a brown-eyed woman whose mother has blue e
nlexa [21]

Answer:

50%

Explanation:

This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.

According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).

Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.

Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.

Temporal lobe which spans both cerebral hemispheres of the brain and below the lateral fissure is significant in interpreting sensory information. Its communication with the hippocampus is also vital for the long-term memory. There is a visual area in the temporal lobe that processes   and interprets visual information from the eye hence one is able to recognize objects.
