The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence

Explanation:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.

The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The show follows the home and academic life of several researchers

polet [3.4K]

There are several information's of immense importance already given in the question. Based on those information's the answer can be easily deduced.
Initial number of bacteria in the culture = 1000
Number of bacteria after t hours = 1000 (2)^t
Then
1000 (2)^t = 50000
2 ^t = 50
t = 5.6

I hope the procedure is clear enough for you to understand.

A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

Explanation:

The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

This phenomenon between the differences in land and water temperature causes land sea breeze to occur.

Water has a very high specific heat capacity.
This implies it takes more heat to cause a monumental increase in its temperature.
It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.

A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.

Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.

guajiro [1.7K]

Answer: Promoter

Explanation:

Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called RNA polymerases which perform this process of transcription. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.

A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is and contains the information needed to activate or deactivate the gene it regulates. The promoter has a binding site for the RNA polymerase enzyme in charge of mRNA synthesis and when it recognizes this site, transcription begins.
