29. A teacher presented the two models below to the dass. The models represent a eukaryote and prokaryote cell. The teacher asked the students to label the structure of each cell that contains the genetic code and
tell where it is located.
structure C, located in the cytoplasm in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the nucleus in Cell B
structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the cytoplasm in Cell B
Answer:
C. structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
Explanation:
This question contains images that depicts an eukaryotic cell (animal) and a prokaryotic cell (bacteria). According to the question, a teacher asked the students to label the structure of each cell that contains the genetic code (DNA) and tell where it is located.
In an eukaryotic cell, the genetic material (DNA) which contains the genetic code is located inside a well defined membranous structure called NUCLEUS while the genetic material in a prokaryotic cell is found naked in a region of the cytoplasm called NUCLEOID as they lack a membrane-bound nucleus. Based on this explanation;
- Structure C is the genetic material (DNA) which contains the genetic code of cell A (eukaryotic cell), hence, the genetic code of cell A is found in structure C, which in turn is located in the centrally-placed NUCLEUS.
- Structure C is the genetic material containing the genetic code of cell B (prokaryotic cell), hence, the genetic code of cell B is found in structure C, which in turn is located in the CYTOPLASM.

Why would the "fixed migratory pattern" of the blue whale or sea turtle make these species vulnerable to extinction?
Answer:
Taking a fixed migratory pattern would be unpleasant for whales, whales already have a low reproduction rate, having a fixed pattern would decrease it's encounter with other whales, this decreases the low chance of it's reproduction.
Explanation:
The migratory pattern would be unpleasant for whales, whales have a low reproduction rate fixed pattern would decrease it's with other whales, this decreases the low chance of it's reproduction.

Greg Developed and Ear infection. His doctor gave him an antibiotic. The antibiotic killed all the bacteria in his body. What other effect could the antibiotic have
Some of the antibiotics doctors prescribe to treat an ear infection such as amoxicillin, cortisporin (neomycin/hydrocortisone) solution or suspension.
What is infection?The infection is invasion and growth of germs in the body. The germs can be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it.
Antibiotics can have side effects as when children take antibiotics at the first sign of an ear infection, they are more likely to have vomiting, diarrhea, and allergic reactions because of the medicine. Also, antibiotics can kill “friendly” germs in the body and cause other problems like diarrhea.

UAA is a codon that signals to stop making a protein, and so it is therefore called a ______
Answer:
stop codon
hope this helps, good luck :)
UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.
What is a codon?Codon may be characterized as a sequence or collection of three consecutive nucleotides in a DNA or RNA molecule that significantly codes for a specific amino acid. These sequences of nucleotides give a signal to the start or end of translation.
A stop codon is also a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA) that specifically signals a halt or inhibits to protein synthesis in the cell. Out of 64 different trinucleotide codons, there are only three stop codons are there, namely UAA, UAG, and UGA.
The start codon is the initial set of codons in an mRNA transcript that is translated by a ribosome. CAG is a start codon. Nonsense codons also play an important role.
Therefore, UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.

What are some examples of climatic conditions that support certain species and inhibit others?
Answer:
The cold temperatures, snow and ice, lack of daylight in winter and lack of darkness in winter, make good conditions for the survival of polar bears, seals, caribou, etc., but seriously prohibit the survival of mosquitoes and most other insects.
Explanation: Here's your answer, hopefully this will be help!
The examples of the climatic conditions that support certain species and inhibit others involved the snow, ice, etc.
Examples of the climate conditions:The cold temperature, snow, and ice, absence of daylight in the winter season, and absence of darkness in winter seasons resulted from the polar bears survival.
But at the same time, it restricts the mosquitoes and other insects survival.

Rinoy wants to electroplate copper on an iron nail.
0 What should he use as the positive electrode and negative
electrode for this process?
(0) Which electrolyte should he use for the process?
(ii) Which of the two electrodes will gradually wear away
during electrolysis-anode or cathode?
Answer:
See explanation
Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
