A piece of DNA from the parent to the offspring.
For example when you were born you're mum transferred some of her traits (hair color, personality ect.) on to you. Same with your dad. So you might look like your dad but have the same personality as your mum.
Mark me as a brainlest plz! hope this helps :)
Answer:
<em>B. All living organisms are composed of one or more cells, which came from pre-existing cells.
</em>
Explanation:
Scientific theory is given as an answer to a natural happening in the earth but scientific laws are detailed idea of how nature will act under certain conditions.
Theories are given after an experiment has been performed under controlled conditions. Scientific theory cannot be changed to scientific laws and scientific laws cannot be changed to scientific theory.
Scientific theories are broader in scope, and give overall clarifications of how nature functions and why it shows certain attributes. Similarly, all cells comes from pre-existing cells is an example of cell theory.
They can estimate how old the universe is by testing rocks from different planets and comparing ages and comparing with our earth so since we know approximately how old are earth is we can tell how old the universe is
This might be more answerable if there were a picture to better describe the problem
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>
