Answer:
Explanation:
The theory of uniformatrianism was proposed by James Hutton, a Scottish Geologist by profession.
This theory was a contrast proponent to the tenets of the theory of catastrophism in existence before then in the scientific circles
The theory states that "the present is the key to the past and geologic processes occurring today have happened in the times past".
- The theory correlates geologic processes as continuous in nature rather can punctuated situations.
- Erosion occurring today has been changing the land surface on earth as far back into the geologic times and periods.
- From the image, the erosional activities are still continuing today.
Answer:
Courtney is looking at Prokaryotic Cell.
Explanation:
Ok, when Courtney is observing the science experiment, and finds a cell that includes DNA and has a nucleoid region but does not have nucleus, it is a prokaryotic cell and only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes, where pro means before and kary means nucleus.
Let's explain what is a prokaryotic cell: prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. And most prokaryotes have a cell wall outside the plasma membrane.
Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
Hey there!
Here is your answer:
Since there are not options im going to go with what i know:
<u>(Alleles)</u>
<span><u>heterozygous: A,a</u>
</span><u>homozygous: a,a</u>
<u>Therefore the Punnett square should look like this:</u>
<u>A, a</u>
<u>a IA,a I a,a</u>
<u>a IA, a I a, a</u>
Therefore the answer is 50% A,a , and 50% a, a!
If you need anymore help feel free to ask me!
Hope this helps!
