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.

In the ovarian cycle, the surge of ______ triggers ovulation.
Cloud [144]

In the ovarian cycle, the surge of LH triggers ovulation.

During evolution when the level of estrogen is sufficiently high, it produces a sudden release of LH, usually around day thirteen of the cycle. This LH peak triggers a complex set of events within the follicles that result in the final maturation of the egg and follicular collapse with egg extrusion.

A surge in LH causes your ovary to release a mature egg around the second week of each menstrual cycle. A high LH level around this time means that you're at that moment in your cycle when you're most likely to get pregnant. Levels of LH are low for most of the monthly menstrual cycle. However, around the middle of the cycle, when the developing egg reaches a certain size, LH levels surge to become very high.

Answer:

1.) 80 chromosomes in each of the daughter cells. 2.) Two daughter cells are produced. 3.) The daughter cells are identical.

2.) The parent cell divides to form the two daughter cells in cytokinesis.

3.) The daughter cells are direct replicas of the chromosomes in the parent cell unless there is a mutation in the DNA when it is being copying.
