Construct a Punnett square for the following cross. A woman who is a colorblind carrier marries a man who is colorblind. What will be the chances of their sons also being colorblind? What will be the possible phenotypes of their daughters?
Answers
By colour blindness you mean red-green colour blindness I guess because there are different kinds of colour blindness.
Red-green colour blindness is a s.e.x-linked recessive trait disease, which is encoded on the X chromosome. So following are the result of a cross of colour blind men and carrier women:-
1 normal boy (XY)1 Normal girl (XX)1 Carrier girl (XcX)1 Affected boy (XcY)First cross, by the method of punnet square
Look at pictures now!
Conclusion: there are 50-50 chances of both the result.

Which of the following statements most accurately describes the outcome of cell division by mitosis?
Choose 1 answer:
Cell division by mitosis reduces the amount of genetic material in each daughter cell by half.
Cell division by mitosis results in daughter cells with different genes, allowing the cells to carry
out different functions.
Cell division by mitosis results in two daughter cells that are genetically identical to the parent
cell.
Answers
Answer:
Cell division by mitosis results in two daughter cells that are genetically identical to the parent cell.
Explanation:
Cell division by mitosis results in two daughter cells that are genetically identical to the parent cell. The correct option is C.
What is mitosis?Mitosis is the process, a cell replicates and then splits its chromosomes, creates two identical nuclei in prep work for cell division.
Mitosis is usually accompanied by the equal division of the cell's material into two daughter cells with exactly identical genomes.
Mitosis occurs in the following stages: The chromosomes shorten and thicken during prophase.
Metaphase - Chromosomes align in the center of the cell. Chromatids splits at the centromere and start moving to opposite poles during anaphase.
Telophase - The formation of two nuclei after nuclear envelopes reform around each chromosome group.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Thus, the correct option is C.

What type of cell is Cell City and what type of cell does Celley come from?
Answers
The eukaryotic cell is a type of of cell city and the type of cell celley comes from is from a prokaryotic (bacterial) cell.
What is a cell?Cell is defined as structural, functional and simplest unit of life.
Eukaryotic cell and Cell city analogyBy analogy, If we compare an eukaryotic cell to a city,
Then, the eukaryotic cell's nucleus, from which everything is directed, is the City Council. It's responsible for the design of operations within the cell, the DNA, for the city is contained in there and nothing will happen without it.Additionally, the cell membranes are analogous to the city walls and hence, everything outside the cell membranes is outside the city's jurisdiction.
What is a bacterial cell?Bacterial cells come in many shapes and sizes, and essentially, bacteria are prokaryotes, with chromosomes composed of a single closed DNA circle and lacking well-defined nuclei and membrane-bound organelles.
E.coli as a prokaryotic cellEscherichia coli., like many other bacteria cells lacks a membrane bound nucleus and have genetic material floating over the cell cytoplasm. Additionally, they lack cell organelles like Golgi body, etc.
On this note, one can conclude beyond reasonable doubt that E. coli is a prokaryotic organism.
There are two types of organisms based on the numbers of cell they have:
Unicellular organisms: Organisms with only one cell.Multicellular organisms: Organisms with more than one cell.Learn more about prokaryotic and eukaryotic cells:

Answers
The process mitochondria use to make energy in the form of ATP is called cellular respiration. It is the powerhouse of cells. Using the oxygen available within the cell, mitochondria convert chemical energy from within the cell into ATP energy that the host cell can use.
This process is called oxidative phosphorylation. In the mitochondrial matrix, a chemical called NADH is produced by a reaction known as the citric acid or Krebs cycle. NADH is then used by enzymes embedded in the inner membrane of mitochondria to generate adenosine triphosphate.
