Region of the World                             Percentage    Value in Metric tons
North America                                          17                  23,332,500
Asia                                                          52                  71,370,000
Africa                                                          3                    4,117,500
Europe                                                     18                  24,705,000
Latin America and the Caribbean              8                  10,980,000
Oceania                                                  <u>   2</u>                <u>    2,745,000</u>
                                                               100                137,250,000

We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.

Asia uses 71.37 million metric tons.

In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.

Why is heritable variation important for both artificial and natural selection.
Julli [10]

Identify and describe the various satellites the orbit in our solar system.
Hitman42 [59]

Answer:

Explanation:

The seven largest natural satellites in the solar system (over 2,500 km in diameter) are the four Jovian Galilean moons - Ganymede, Callisto, Io, and Europa - Saturn's moon Titan, Earth's own Moon, and the satellite captured natural of Neptune Triton.

They move around a larger body. They revolve around these bodies because of their gravitational pull. The orbits that they describe when turning on these bodies can be regular or irregular.

Natural satellites of planets in the Solar System

Mercury → 0.

Venus → 0.

Earth → 1.

Mars → 2.

Jupiter → 79.

Saturn → 82.

Uranus → 27.

Neptune → 14.

Which of the following is a reason why sticky end producing restriction enzymes are preferred compared to blunt end ones?
anyanavicka [17]

Answer:

D) Because sticky ends can be temporarily held together by hydrogen bonding between the two strands.

Explanation:

Restriction enzymes cut the DNA at specific restriction sites and by the mechanism of action they can form two types of ends:

  • sticky ends-single-stranded overhangs are formed
  • blunt ends-without overhangs.

The main advantage of sticky ends (their overhangs) is that they can complementary bind to another overhand formed by the same restriction enzyme. So, for example in cloning, if the DNA of interest and plasmid vector are cut with the same restriction enzyme, that  forms sticky ends, fragment of DNA will fit into a bacterial plasmid in one direction.

On the other hand, blunt ends can be inserted into vector in both directions: head-to-tail or tail-to-head.
