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.
Haploid. This means that the cells produced during the second meiotic division contains only one set of chromosomes. During mitotic division, the cells produced are diploid. This means that they contain two sets of chromosome. There is a pair of each chromosome. However, a haploid cell contains only one chromosome out of the pair. The production of haploid cells by the second meiotic division produces gametes or sex cells. It is essential that gametes have only one set of chromosomes since gametes combine during sexual reproduction. It then allows for the correct two sets of chromosomes to be found in the offspring.
Relative dating best helps determine fossil age. It's where layers of sedimentary rock and fossils pile up on top of each other; the oldest fossils being in the bottom layer and the youngest in the top.
Answer: A) genes involved in the cell cycle.
