Persian cats often have certain diseases and disorders, especially of the eye and nose since their heads have an unusual shape. Persian cats were developed by artificial selection by humans.
Which of the following traits is deliberately selected for when breeding Persian cats?
A.
flat faces
B.
inherited diseases
C.
genetic diversity
D.
all of these
Answer:
the answer is A
Explanation:
It couldn't be D or C because you don't want to give your cat a diseases and so that means it couldn't be D which is all of the above.
Your stomach pH is about 2. Would you expect starch
digestion to take place in the stomach?
Answer:
The correct answer would be - no or very less.
Explanation:
Digestion of the carbohydrates including starch begins within the mouth with the help of amylase into maltose. Most of the starch digestion takes place in the small intestine.
The significant digestion of starch does not take place in the stomach due to the acidity of the stomach as at low pH, amylase denatured or stay inactivated. Once the starch fragments reach the small intestines pancreatic amylase digest starch.

Put the following events of eukaryotic translation in chronological order:
1. Binding of mRNA and ribosome at the mRNA start codon
2. Stop codon releases the ribosome and translation stops
3. Complementary base pairing between initiator codon and anticodon of initiator tRNA
4. Peptide bond formation between amino acids
5. Release of Finished protein product
Answer:
1, 3, 4, 2, 5
Hope it helps!
Proteins translation occurs in the cytosol. It involves the association of mRNA to the ribosome and to tRNA. The codons determine the amino acids sequence. The order is 1, 3, 4, 2, 5.
------------------------------
Protein synthesis involves transcription -which occurs in the nucleus-, and translation -which occurs in the cytosol-.
Once in the cytoplasm mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes might be floating freely in the cytoplasm or attached to the rough endoplasmic reticulum.mRNA and ribosomes also associate with different tRNA that carries amino acids.The ribosome recognizes the start codon in the mRNA and starts reading the strain in a 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain.
Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.
The new amino acid joins the growing chain through peptidic bonds between the carboxyl and amino groups. The tRNA leaves the ribosome and sets free to join another amino acid and repeat the cycle.
The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA.
When the ribosome meets the stop codon, protein synthesis finishes. The polypeptide is released.
The correct order of steps is
1. Binding of mRNA and ribosome at the mRNA start codon
3. Complementary base pairing between initiator codon and anticodon of initiator tRNA
4. Peptide bond formation between amino acids
2. Stop codon releases the ribosome and translation stops
5. Release of Finished protein product

Explain why an area with extreme temperatures like one in the Arctic would be resistant to invasion by a biotic disturbance.
Answer:
Negative responses protect our body by taking the deviation and making it less harmful to the body. When you cut your finger and lose blood, negative feedback kicks in to slow and stop the flow of blood.
The reason of area having high temperatures should be because of the negative response.
Reason of area with extreme temperatures:Due to the negative response, it protect our body by considering the deviation and it make less harmful to our body.
Also, when you cut the finger and blood comes so there is the negative feedback that kicks for stopping the blood flow.

For the following template
DNA sequence:
3 TÁC AGA - GGT -
TCG - ATC 5'
a) provide the amino acid
sequence
b) provide the anticodons in
order
c) Mutate the above DNA
sequence to introduce a
silent substitution. Write the
mutated DNA sequence
down.
Make sure to clearly
indicate if your answer for
each part by labeling it a) or
b) or c)
Answer:
a) Methionine- Serine- Proline- Serine- STOP.
b) UAC- AGA - GGU -
UCG - AUC
c) AUG- UCG- CCA- AGC- UAG
Explanation:
A) The DNA sequence in this question is given as follows: 3 TÁC -AGA - GGT -
TCG - ATC 5'. This sequence undergoes transcription and translation (gene expression) in order to give rise to an amino acid sequence.
The mRNA sequence that will result following transcription is: AUG- UCU- CCA- AGC- UAG
Following translation, each codon in the above mRNA sequence will result in the following amino acid sequence: Methionine- Serine- Proline- Serine- STOP.
B) Anticodons are a group of three nucleotides that are complementary to a codon found on the tRNA molecule. The anticodons for each codon on the mRNA sequence is: UAC- AGA - GGU -
UCG - AUC
C) Silent mutation is a type of substitution mutation in which one or more nucleotide base is replaced by another in such a way that it does not change or alter the amino acid sequence. Using the mRNA sequence: AUG- UCU- CCA- AGC- UAG
A mutated sequence is as follows: AUG- UCG- CCA- AGC- UAG. Note that, G has replaced U in the second nucleotide. However, there is no change in amino acid that results because the same UCU that codes for SERINE is also encoded by UCG.
The red shift of light from most galaxies is evidence that
Answer: This means that the further away the galaxies are, the faster they are moving. ... Red-shift data provides evidence that the Universe, including space itself, is expanding. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.

What process moves the water from the roots to the leaves
Answer:
The process is called transpiration stream. in plants transpiration stream is the uninterrupted stream of water and salutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast- interface of the substomatal cavity. it is driven by capillary action and in some plants by root pressure.

which describes how mRNA is used by a cell?
A it is used to stop toxins from entering the nucleus
B it is used to prevent mutations in DNA
C it is used to transfer info to the ribosome
D it is used to replicate DNA for meiosis
Answer:
C it is used to transfer info to the ribosome
Explanation:
The ribosome is responsible for the production of proteins, so when mRNA enters a cell, the code is sent to the ribosome so that it can begin constructing the proteins.

Imagine you are a forensic investigator giving a presentation to a school assembly. A student asks you, “If people have such a similar genetic makeup, then why do you use DNA to understand whether suspects are innocent or guilty of a crime?” Describe how you might answer the students question.
Answer:
While at first, it might look like everyone had similar genetic makeup the human genome is actually incredibly complex we each have an individual set of our own genetic makeup even identical twins have different sets. Another factor is other evidence we have, you can not solely decide if someone is innocent or guilty on a single piece of evidence.
