Answer: Option (a) is the correct answer.

Explanation:

An atom consists of three sub-atomic particles namely protons, neutrons, and electrons.

Protons have positive charge, neutrons have no charge, and electrons are negatively charged.

Protons and neutrons reside inside the nucleus of an atom whereas electrons revolve around the nucleus of the atom. The electrons which are in the outer most shell take part in a chemical reaction and thus leads to formation of new compounds.

Hence, we can conclude that the outer electrons are the parts of an atom that are involved in chemical reactions.

Can someone help me with that question

Answer:

fine details such as the wings, legs and other fragile structures are preserved effectively giving us a window into how the preserved organism would have appeared in life. without the presence of amber, we wouldn't be able to examine a majority of small prehistoric organisms.

Explanation: amber is able to preserve a snapshot of the ancient world in ways that other forms of fossilization simple fails to do. while an imprint of a feather could be preserved in rock the actual feather could be captured within amber. Amber also preserves small organisms that otherwise would have been lost to time such as the insects seen in the photo above.  And much like the gecko seen below it can show us how these organisms truly appeared in life.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

what is the difference between the closed conformation and open conformation of chromatin packing? biology
Oduvanchick [21]

The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.

  • The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
  • With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
  • All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
  • While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.
