<span>The answer is B) independent assortment. The principle of the independent assortment was originally stated by Gregor Mendel. It explains that the random and independent distribution of homologous chromosomes occurs during cell division meiosis. This gives different traits an equal opportunity to inherit together.</span>

Based on the estimates of Alfred Wegener approximately when did the supercontinent called Pangea begin to split apart?

77julia77 [94]

Answer:

Option: a. 200 million years ago

Explanation:

Million years ago, Earth had one supercontinent called Pangaea and surrounded by an ocean (Panthalassa). Alfred Wegener proposed the concept of one big continent after putting together different records of confirmation. He was able to give his theory by examining fossils of plants, trees, animals, and reptiles that found in different continents. About 200 million years ago, the supercontinent began to split up into two parts; Gondwana from Laurasia. Today's countries, including Africa, Antarctica, India, South America, and Australia are part of Gondwana, where Europe and North America from Laurasia.

Why do the poles have the coldest climates on earth?

Hi there!

The answer is 3., but 1. is VERY close to the correct answer. 1. is incorrect, because the sun's rays do not slant, but the Earth does.

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5). What is the equation of the line parall

DENIUS [597]

Answer:

y=4x-16

Explanation:

The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.

Given points (-3,-3) and (-1,5)

We are to find the equation of the line parallel to the given line with an x-intercept of 4.

First, we determine the value of the gradient of the line.

Gradient,

$m=\frac{y_2-y_1}{x_2-x_1} \\=\frac{5-(-3)}{-1-(-3)} \\=\frac{5+3}{-1+3}\\=\frac{8}{2}\\m=4$

Two lines are parallel if their gradients $m_1 \: and \: m_2$ are equal.

The gradient of the line parallel to the given line $m_2=4$

Since the x-intercept of the new line is 4, a point on the new line, $(x_1,y_1)=(4,0)$

Substituting $(x_1,y_1)=(4,0)$ into the equation of a line: , $y-y_1=m(x-x_1),$ we have:

$y-0=4(x-4)\\$Therefore:\\y=4x-16$

Therefore, the equation of the line is: y=4x-16
