Answer:

In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>

Explanation:

The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.

Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.

Answer:

What came before the big bang.

Explanation:

The Big Bang Theory is a model for the origin of the universe. The model describes the change that the universe has gone through from its conception. It argues that the universe expanded from a high-density and high-temperature state. However, one of the questions that remain unanswered is what came before the Big Bang, as we do not have the knowledge yet to determine whether this event was primordial.

The mechanism that breaks the linkage between linked genes is
gregori [183]

Answer:

Crossing over

Explanation:

Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.

Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.

The cell model below shows 2 solutions separated by a selectively permeable membrane indicated by the red dashed line.
e-lub [12.9K]

So naturally, Water loves to be with water. This is just a common knowledge of biology. The side with the least amount of water will recognize that the opposing side has more water. Water molecules in Side A will essentially try and cross the selectively permeable membrane and go onto the crowded side. This will make the Cell in A become lysed and it will shrink. Your answer will be:


C. The Water level will increase on side B and decrease on Side A until concentrations are equalized.

Illusion [34]

Answer:

D

Explanation:

Bacteria can reproduce quickly which is why it is sometimes hard to get rid of a cold.
