B. an increase in the overall temperature of the Earth
I say this because the polar ice caps on the poles are melting (which is why the polar bear is now endangered.) and are a result of global warming.
Overhunting and overfishing can cause animal populations to grow endangered or become extinct.
Answer:
c = 55° and d = 125°
Explanation:
Given that,

We need to find the measure of angle c and angle d.
We know that the sum of angles of a triangle is 180 degrees. So,
a+b+c = 180
85+40+c = 180
125+c=180
c = 180-125
= 55°
Using exterior angle theorem,
d = a+b
d = 85+40
d = 125°
Hence, c = 55° and d = 125°
<span>Mercury has 0.0553 earth's mass and has no natural satellite. It
is the planet closest to the sun and also the smallest, its surface is
rocky and solid like the earth, has a diameter of 4879 km and is formed
mainly of metal elements. <span>Its orbit around the sun is 88 days and its temperatures are extremely high due to its proximity to the sun.
