Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle, while Eukaryotic cells contain membrane-bound organelles, including a nucleus.
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
Answer:
ans is A long term energy
storage
Answer:
B There will be blue colonies only
Explanation:
This screen in called the blue white screening. This is a rapid test that allows scientist to check for their insert of choice in the colonies at a glance. The concept is that where the insert is located the <em>lac Z </em>gene in the vector is interrupted and therefor Xgal, a reporter can be produced. Where there are blue colonies being formed the plasmid has self-ligated and the <em>lac Z</em> gene is not interrupted and the X-gal can be formed rendering a blue color.
Answer:
Scientists are studying a group of ant colonies in the Arizona desert. Which question about the ants can be answered scientifically?
Explanation:
The correct answer will be option- Does the amount of sunlight in a day affect how much food the ants eat that day.
Explanation:
A scientific method is a systematic approach to understand and explain any natural phenomenon in nature. The scientific method involves making, ask a scientific question, do background research and propose a hypothesis which could be tested to produce a real answer to the scientific questions.
In the given question, the scientist wants to study the ants in the desert through scientific method. The possible question that could be answered will be the how the amount of light can affect the quantity of food consumed by ants as the amount of food can be studied through the experiments by proposing a hypothesis.
Thus, the selected option is the correct answer.
