Answer:
They are caused by an increase in global temperatures
Explanation:
Global warming will cause a change in the weather patterns of a region – called climate change. A place could experience extreme weather such as increased dryness or wetness. This is mainly due to takeup of this heat by the oceans hence influencing global currents.
As the oceans become warmer, they are able to absorb more carbon dioxide from the atmosphere. This causes these water to have a higher acidity than normal because of the formation of carbonic acid.
The answer is <span>C) Bb x Bb
</span>
B - the allele for black and white coloration
b - the allele for brown and white coloration
There are in total 11 offspring (<span>8 black and white and 3 brown and white),
In a monohybrid cross when both parents are heterozygous (Bb), the phenotype ratio is 3:1. We have ratio 8:3.
The ideal ratio would be 9:3 because it is the same as 3:1.
Therefore, the parents Bb and Bb will have </span>8 black and white and 3 brown and white with the ration 8:3 ≈ 9:3 = 3:1

Answer:
c
Explanation:
serotonin as it has neuro cells which can be fixed changed or duplicated.
This model of red and orange lines represents the process of transcription.
The 5' labels refer to the end of the strand with a nitrogenous base. false
The 5' label at the end of the DNA strand refers to the phosphate group of the last nucleotide of the strand.
The model correctly shows an arrowhead on the 3' ends of the strands. false
The arrowhead on the 3' ends of the DNA is incorrectly put there. This is because arrowheads are only used to show the direction of the formation of RNA.
The 3' labels refer to the end of the strand with a phosphate group. false
The 3' labels refer to the end of the strand with a hydroxyl group of the last nucleotide of the strand.
Hydrogen bonds between the red and orange strands are not shown but are implied by the model. true
The newly formed RNA molecule is bound to the template DNA with hydrogen bonds. Normally, models describing the transcription process need to show the presence of the hydrogen bonds.
The red lines represent DNA. true
The red lines represent the unwinded double-stranded DNA.
The orange lines represent RNA. true
The orange lines represent the RNA molecule formed based on the template strand of nucleotides
The model shows the correct polarity between the orange and red strands. false
The RNA polymerase builds the RNA molecule by creating a strand that grows from 5' to 3' (this is correctly shown at the model). However, the template strand of DNA is read by the DNA polymerase in the 3' to 5' direction. Therefore, the model needs to show that the RNA molecule is bound to the other strand of DNA, the one with the 3'-5' direction.
