14 1: According to your observations, how many cells are in anaphase?
A: 19
2: Place the phases of a stem cell in the correct order.
A: mitosis, gene expression, differentiation
3: What general type of cells do fibroblasts make?
A tissue
4: During mitosis, what happens to the parent cell?
It produces 2 daughter cells
5: In which phase of mitosis do the chromosomes line up along the center of the cell?
A: metaphase
6: Immediately after an embryo forms, it begins to replicate new cells. What type of cells are most likely to form during early divisions?
A: totipotent cells
7: Why is mitosis a longer and more complicated process of cell division than binary fission?
A: Mitosis has checkpoints that must be met to continue the cycle
8: Some differentiated cells almost immediately become senescent, exit the cell cycle and undergo terminal differentiation. Other cells have a great need to proliferate to grow and repair the organ or tissue, so they do not go into senescence for a long time. Which cell type would be most likely to delay senescence and terminal differentiation so that it could continue to replicate in order to grow and repair itself?
A: skin cells
9: When scientists and doctors seek to heal wounds and cure disease, stem cells are a great option because they can repair damage and grow new specialized cells. From the list, which type of stem cell would be the best option for curing the widest variety of diseases?
A: embryonic stem cells
10: How important are microtubules in cell division?
A: They organize and separate the chromosomes
11: How does cell differentiation differ from mitosis?
A: Cell differentiation produces cells with different gene expressions
12: What type of cell is shown in the figure?
A: diploid cell
13: What is a force in the figure?
A: The figure shows where mitosis occurs in the cell cycle
14, 15, 16, 17; Good luck with the trials I’ve been in this prison for a while I think it’s time to face the questions myself wish me good luck everyone I won’t be back on Jiskha until my next mission Here are the written responses which are 3-5 sentences as required.
Raul learns about fetal development but is confused about the role mitosis plays in fetal growth. In 3-5 sentences, explain what mitosis does in fetal development. Include how the same DNA is found in each cell and how the fetus grows. (4 dots)
Mitosis is the reason the fetus grows. It does this by doubling and dividing the chromosomes. By doing this, growth occurs. Most fetuses will be born within 40 weeks of pregnancy, but in reality only about 5% of babies born two weeks early or two weeks late are normal.
In three to five sentences, explain the advantage of keeping some of the DNA needed for mitochondria in the cell nucleus and some in the mitochondria itself. (4 marks)
Mitochondrial DNA is the small circular chromosome present inside the cell organelle called mitochondria used for energy production. This type of DNA is passed from mother to offspring. Mitochondrial DNA (mtDNA) has several advantages over nuclear DNA such as species identification including higher copy number, absence of sequence ambiguities of heterozygous genotypes, higher mutation rate faster.
In 3-5 sentences, construct a summary of the gene expression process, starting with DNA and ending with proteins. (4 dots)
The process of gene expression begins with the transcription of genetic information contained in DNA into genetic codes in the form of messenger RNA. The messenger RNA then undergoes processing such as tail modification and removal of the non-coding sequence before the genetic codes are translated into their respective amino acids in a process known as translation. Amino acids are linked together by peptide bonds and the resulting primary protein structure is folded in specific ways according to their functions.
In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
Maps have the advantage of objectivity and presentation of all phases of mitosis, but their disadvantage is the suppression of information, which can confuse students. A scientific model (or map) should be able to show a scientific process or thing as it actually occurs, or as close to it. These maps should be objective, direct and well explained, allowing students to understand what they present. About the maps presented in the question above, it can be said that the first one presents the phases and the results of mitosis in a very representative way, but it removes the name of the phases, which can confuse the student. The second presents the names of the phases, but does not show what happens in each of them, which can also confuse the student. The answer is actually 19 Yeah thanks a million Sage Angel, 2 questions were missing from my test but that’s not a problem. Assuming you’re not honored, the 2 questions you haven’t covered are:
DNA is encoded into RNA, which must travel from the nucleus to the cytoplasm to be read. Why does the cell need to transcribe DNA into RNA rather than copy DNA directly?
A: DNA is double stranded and cannot pass through the nuclear membrane; RNA is single stranded.
How many cycles of mitosis produce 64 daughter cells?
A: 6 What about the whole test? Thanks! I have to look for essay questions but thanks Sage Angel, really helpful Thanks sage angel Tsym this helped a lot lol Lifesaver Sage Angel lifesaver. thank you a real help, you are a real help Thank you wise angel! Oh my Connexus Prisoner #891002. Lol. See you later, my partner Sage Angel is a real jerk here. Thanks!!!!! Thanks man Thanks @real help and @Sage Angel. 💕 I think the answer is 41
