Answer:

a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol

Explanation:

All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.

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.

ioda

When a person  see a cell with blue fills of varying lengths representing the values, the cells most likely have data bars applied to them.

<h3>What are Data bars?</h3>

Data bars are known to be a kind of  conditional formatting that alters based on the data that is said to been shown.

The bigger the number, the fact still remains that the  longer the bar that appears in a cell. They often do look like an advanced feature but they are said to be easier to input the data bars to a spreadsheet in Excel using few clicks.
