Answer:

Bacteria reproduce by binary fission

Explanation:

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.

Binary fission begins when the DNA of the bacterium divides into two (replicates).

Genetics Problems (ABO Blood System) The chart below lists the blood phenotypes of 8 individuals. Use the information in the cha
Setler79 [48]

Answer:

Explanation:

Female blood type   Male blood type

Anne Type O            Charlie Type A

Wendy Type B          Scott Type AB

Susan Type AB         Larry Type O

Patricia Type A         Keith Type B

1. Larry has a son with type B blood. Which of the females listed above could be this child's biological mother?

For Larry that is of type O to produce a son with type B blood, his mother has to be either of type B or AB. Which is either Wendy or Susan

2. Anne is pregnant with Scott's child. What is the chance that the baby will have type A blood?  

Since Scott possess the AB codominant type and Anne's type has to be inherited in the recessive form, the chances of producing type A is 50% and B is 50%. Thus, the chance that the baby will be of type A blood is 50%.

3. Because her daughter has type B blood, Patricia insists that Keith is the father. Keith claims that Scott is the father of Patricia's baby girl. Is it possible that Scott is the baby's father?  

Since Scott that is of type AB is the father of a type B child, the mother Patricia that is of A type has to have a genotype that is AO for it to be  possible that Scott is the father.

4. Keith and Wendy have a 4-year old with type O blood. How is this possible?

Keith is of type B blood and Wendy is also of type B blood. It is possible to have a 4-year old with type O blood if if both parents are of the BO genotype.

5. Susan is the mother of Charlie's first two children. The oldest, Dawn, has type AB blood while her sister, Kate, has type B blood. Charlie is now expecting a baby with Anne. What is the chance that this child will have type O blood?

Charlie and Susan can only produce Kate of type B blood if they are AO and AB respectively. Thus, since Charlie's genotype is AO, there is a 50% chance that he can produce a child of type O blood with Anne who is of type O blood.

6. Erin, Patricia and Larry's daughter, is married to Jeff. Jeff was in a serious car accident and needs a transfusion but Erin is told that Jeff cannot be given her blood. Based on this information, provide Erin's blood genotype and blood phenotype.

   For Erin to be unable to give her blood to Jeff, it means Jeff is of O blood type and Erin is not, meaning she can either be A+, B+ or AB. But since her mother is of type A and father is of O, this rules out AB and also B.  Her genotype can't be AA since her dad is of type O blood. Thus, it can be claimed that she is of genotype AO of type A blood type.

7. Scott and Susan's son, Paul, is willing to donate blood to a young girl with leukemia. If the recipient has type O blood, will Paul be able to donate to her?

Since the recipient has type O blood, she can only receive from a type O patient. Paul cannot be a donor because both parents are of AB blood type meaning Scott is either of type A, B or AB. Thus, he will not be able to donate as he is not of O type.

A researcher is carrying out an experiment where she labels a protein with a fluorescent tag (so she can visualize its location
melisa1 [442]

Answer:

The protein likely travels through a common lumen shared by thylakoid membranes and grana, and cannot easily diffuse through the thylakoid membrane.

Explanation:

There is a lot of scientific research in which a specific molecule can be labeled with some fluorescent marker (usually carbon 14). This type of marking allows the researcher to make observations about the movement of these molecules, as you can see in the question above. About the research shown in the question, the researcher realized that the protein labeled with the fluorescent marker moved between the grana and was always in the lumen, so she can conclude that the selocomovement protein moved through the lumen that is shared between the tilacoid membranes and the grana.
