Answer:
I think it decreases the activation energy needed for the reaction to start.
Explanation:
I think that's right but it's not an answer choice.
Answer:
It provides structre and support :)
Explanation:
In this image we can see that A is identical to B, and C is identical to D.
Chromatid (Cht) is a
DNA molecule (the nucleofilament) associated with
histone proteins (PH) and
non-histone proteins (PNH)
<span>Each chromosome of a cell may consist of one or two chromatids depending on its state: just after a mitosis, or after the second meiotic division, each chromosome consists of only one chromatid, the rest of the time,
after DNA replication, each chromosome consists of two completely identical chromatids, connected by the centromere, thus giving the two rods the shape of an X.</span>
Answer:
<u><em>The correct option is D) His results gave the first evidence that atoms were made up of smaller particles.</em></u>
Explanation:
Before the experiments performed by Thomson,scientists believed that atoms were the smallest particles with no sub units. The experiments performed by Thomson provided evidence that atom is made up of even smaller particles. The cathode ray experiment performed by Thomson led to the discovery of electrons which are the negatively charged particles of an atom. The protons are the positively charged particles of an atom. Whereas, the neutrons have no charge.
