Answer:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest
Explanation:
Among the given choices:
A) Of the stars listed, Proxima Centauri and Barnard's Star appear red because they burn the hottest.
This is not the correct answer because temperature of Barnard's star is 5000° F which is lowest in the data.
C) Small dwarf stars, like Proxima Centauri and Barnard's Star, do not burn as hot as medium dwarfs.
Proxima centauri being a small dwarf has a higher temperature than sun which is a medium dwarf.This shows that small dwarfs can burn hotter than medium dwarfs. So this option is not suitable.
D) Proxima Centauri and Barnard's Star are the closest because they are classified as "small dwarfs."
This is not correct choice because the data clearly states they are at greater distance.
So ,the correct choice is:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest.
Because: Sun is closest to the Earth and thus will appear the brightest as maximum light from it Reaches the Earth. Barnard's star is Farthest so less light reaches the Earth from it and it appears the dimmest.
Answer:
When ATP molecules are used to fuel movement.
Hopes this helps :))
The correct answer would be D), over millions of years, Pangaea broke apart and drifted to form the seven continents.
Answer:
The correct answer is an element.
Explanation:
An element refers to a component whose atoms comprises a similar number of protons, or it can be said that the atoms of a specific element exhibit the same atomic number. Chemically, they are the simplest components, which cannot be further differentiated by any chemical means. The elements can get converted into other elements with the help of nuclear methods.
Biotechnology, by the word itself is a technology that is centered in
biology. It is the exploitation of biological process. Biotechnology has
harness the cellular and bio molecular processes to develop technologies and
product that help us elevate our lives. With the help of biotechnology, we are
able to modify the products for its specific use. Let me give you an example of
the following:
<span>1. </span>Medicine: In medicine, the modern biotechnology had
provided products that could combat rare diseases. Currently, around 250
biotechnology health care products and vaccines were made as well as those that
are known to be untreated.
<span>2. </span>Agriculture: With the help of biotechnology, we can
reduce some of the environmental footprint. It has been reported that it is
more than 13.3 million farmers used biotechnology products to prevent damage
from the yield cause by the pest.
<span>3. </span>Conservation: Biotechnology also help us reduce
greenhouse gas emissions.
