Summary Introduction

Introduction:

The concentration and percentage of body fluids and water varies according to the age. The percentage of body fluids decreases with the increase in the age of the person.

Answer to Problem 1DYKB

Correct answer:

The percentage of water is highest in an individual (lean) male athlete with age of 35years . Therefore, option d. is correct.

Explanation of Solution

Reasons for the correct statement:

Option d. is given as “a lean 35years -year old athlete”.  The concentration and volume of water decreases with age therefore the percentage of water will be highest in an individual of 35years of age.

Hence, option d. is correct.

Reasons for incorrect statements:

Option a. is given as “a frail 76 - year-old woman”. The percentage of body weight will be less in a 76 year old person. Hence, option a. is incorrect.

Option b. is given as “a chunky 52 -year old male athlete”. The percentage of water will be less in an 52 old male athlete. Hence, option b. is incorrect.

Option c. is given as “a healthy 88 -year old man”. The percentage of water will be less in a person of age 88 year of age. Hence, option c. is incorrect.

Hence, options a., b., and c. are incorrect.

Conclusion

Volume and concentration of fluid and water decreases with increasing age, as with the increasing age the amount of skeletal tissue and adipose tissue deposited in the body degrades.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
