B.Two daughter cells created at the end of mitosis
C.A homologous pair of chromosomes
D.Two sister chromatids formed during interphase
Answer:
A.Four daughter cells created at the end of meiosis

Answer:
AGU
Explanation:
AGU and AGC are the two codons that code for the amino acid, Serine. These codons are made of three nucleotides, thus they have a triplet nature. AGU that code for serine is made of Adenine, Guanine and Uracil joined together, carried on the messenger RNA to be added to the growing polypeptide chain
What process occurs during transcription? (2 points)
Synthesis of proteins that are coded for by mRNA
Copying of DNA to form an mRNA strand
Replication of DNA to produce a complementary DNA strand
mRNA folding up by forming complementary bonds with itself
Answer:
Copying of DNA to form an mRNA strand
Explanation:
In transcription, DNA is copied to form an mRNA strand with complementary bases.
The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.
This is the first step of protein synthesis.
This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.
So, the correct answer is Copying of DNA to form an mRNA strand
Answer: The correct answer is Copying of DNA to form an mRNA strand

Which of the molecules above is a tRNA molecule?
none of the above.
A
Ծ Ծ Ծ Ծ
C
B
Answer:
B
Explanation:
Transfer RNA (tRNA) is an RNA molecule involved in the process of translation by which cells synthesize proteins. These molecules (tRNAs) have 76-90 nucleotides in length which form characteristic stem-loop structures, and they are considered adaptor molecules because tRNAs serve as the physical link between the messenger RNA (mRNA) and specific amino acid residues of the growing polypeptide chain. A tRNA is composed of a trinucleotide region (i.e., the anticodon region) that binds to the codon in the mRNA, and a region that attaches to a specific amino acid in order to transfer it to the ribosome, where protein synthesis takes place.

7. You and your lab partner are doing an experiment in the physiology lab. Each of you has an isolated muscle cell and you are supposed to stimulate it with an electrode as soon as its absolute refractory period ends. Your partner has a cardiac muscle cell and you have a skeletal muscle cell. Which one of you will use your electrode more times in one minute
Answer: I will use the electrode on the skeletal muscle cell more times in a minute than my partner will.
Explanation:
Based on the information given, an electromyograph tracing can be used on order to know when to use the electrode for the scenario explained.
An electromyograph is simply a machine that is used for the detection and the recording of the electrical potential that's been generated by muscle cells when such muscle cells are activated.
Due to the fact that a skeletal muscle cell while my partner has a cardiac muscle cell, I'll have to use the electrode on the skeletal muscle cell more times in a minute than my partner will.
A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer). C)Exons 2 and 3 must contain a number of nucleotides that when divided by 3, leaves the same remainder (that is, 0, 1, or 2). D)Exons 2 and 3 must have different numbers of nucleotides. Multiple Choice
Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

a small ball has a volume of 17 ml and a mass of 39 g. what is the density of the ball
Answer:
The right answer is "2.30 g/ml".
Explanation:
Given:
Volume,
= 17 ml
Mass,
= 39 g
Now,
The density will be:
= [tex]\frac{Mass}{Volume}[/tex]
By substituting the values, we get
= [tex]\frac{39}{17}[/tex]
= [tex]2.30 \ g/ml[/tex]

"Red rust is one of the destructive diseases in tea plants which results adverse effect on tea yield. It is caused by a type of algae." Which discipline of Biology is related to explain the above statement? a. Mycology b. Agronomy c. Pathology d. Phycology
Answer:
C
Explanation:
The correct answer would be plant pathology.
The branch of biology that is generally concerned with the study of diseases is referred to as pathology. When such a study has to do with plants, it is known as plant pathology.
Mycology is the branch of biology that has to do with the study of fungi, phycology deals with the study of algae, while agronomy deals with the study of economically important crops.
Hence, the correct option is C.

Jaleel and Lisa are simplifying the expression 2 (x minus 2) + 2 as shown. Jaleel's Method 2 (x minus 2) + 2 = 2 x minus 4 + 2 = 2 x minus 2 Lisa's Method 2 (x minus 2) + 2 = 2 x minus 2 + 2 = 2 x
Answer:
Jaleel is correct
Explanation:
Given
[tex]2(x - 2) + 2[/tex]
Jaleel
[tex]2(x - 2) + 2 = 2x - 4 + 2 = 2x - 2[/tex]
Lisa
[tex]2(x - 2) + 2 = 2x - 2 + 2 = 2x[/tex]
Required
Who is correct
Analyzing the solutions
For, Jaleel; we have:
[tex]2(x - 2) + 2 = 2x - 4 +2[/tex] --- this is correct
[tex]2(x - 2) + 2 = 2x - 2[/tex] --- this is correct
For Lisa, we have:
[tex]2(x - 2) + 2 = 2x - 2+2[/tex] --- this is incorrect because:
[tex]2(x - 2) + 2 \ne 2x - 2+2[/tex]
Hence, Jaleel is correct

How Do Eukaryotic and Prokaryotic Cells Differ?
Answer:
The cell nucleus is the fundamental feature that distinguishes eukaryotic cells from prokaryotic ones. A membrane surrounds the nucleus in eukaryotic cells, separating the DNA inside from the cytoplasm and other organelles. The nucleus of prokaryotic cells is not enclosed by a membrane, thus it is not a genuine nucleus. The nucleoid portion of the cytoplasm is where prokaryotic DNA is found. In comparison to eukaryotic cells, prokaryotic cells are generally smaller and less complicated.
OAmalOHopeO
Answer: The difference between eukaryotic and prokaryotic cells is that eukaryotic cells are those which have a membrane-bound nucleus that contains genetic material, as well as organelles that are also membrane-bound. Whereas, prokaryotes are cells that don’t have a nucleus or membrane-encased organelles.

In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells
Answer:
fat in tissue
Explanation:
Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.
However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
Answer fast pleAse i really need the help
Answer:
Due to different reproduction methods.
Explanation:
Organisms from eubacteria, plantae and animal kingdom are used different reproductive strategies which leads to genetic diversity. Bacteria use asexual reproduction which produces identical offspring while on the other hand, plants and animals use sexual reproduction that produces offspring that is different from plants which leads to variation in the organism so that's why we can say that different reproductive strategies is responsible for genetic diversity.
