Answer:
At the end of DNA replication, each copy is identical to each other (option A).
Explanation:
The concept of DNA replication implies that, from an original molecule, two identical molecules are obtained.
DNA replication is based on a semi-conservative model, since the double strand is separated, and each strand serves as a mold for the synthesis of a new strand. <u>At the end of the replication, two identical DNA molecules will be obtained, each consisting of an original strand and a new one</u>.
The best evidence that the replication process results in two identical molecules is that, otherwise, an individual's genetic information could vary, which does not happen.
The other options are not correct because:
<em> B. The copies cannot be different.
</em>
<em> C and D. They are 100% identical, not partially (50 or 90%) similar.</em>
Answer:
The reactants and the products of photosynthesis and cellular respiration are the same but switched around.
Explanation:
For photosynthesis light energy, carbon dioxide, water are needed to create glucose and the<em> waste product</em> is oxygen. But for cellular respiration the things needed to create energy to move around are oxygen and glucose. Mitochondria (aka the powerhouse of the cell) breaks down the glucose to make ATP energy (Adenosine Triphosphate). Plants store some leftover oxygen for cellular respiration. So basically, photosynthesis and cellular respiration kinda depend on each other.
The correct answer is a series of distinctive anatomical traits that contrast with archaic traits from earlier hominins.
The study of human evolution focuses on the events which led to the development of the human species <em>Homo sapiens</em> as we know it now. The group of hominins includes the modern humans, extinct human species and our immediate ancestors. Earlier hominins possessed some characteristics which are distinctive from the modern humans.
Answer:
Archaebacteria
Explanation:
Carl Woese categorised the bacteria into two domains called the Archaebacteria and the Eubacteria.
The Archaebacteria is the group of bacteria which can survive in the extreme condition as they posses the characteristics of both the prokaryotes and some eukaryotes. The bacteria are known as the extremophiles.
In the given question, the bacteria which lives in the gut of the human uses methane gas and thus are known as the methanobacteria. These bacteria are considered the archaebacteria as they methane for survival.
Thus, Archaebacteria is correct.
