Explanation Gasoline is a petroleum-derived transparent liquid, which is also known as petrol. It is used as a fuel in combustion engines. Gasoline consists of organic compounds prepared by fractional distillation of petroleum. The similarities between digestion in animals and breakdown of gasoline in an automobile are given below: (i) In the process of breakdown of food in animals, the food enters through mouth and the waste product exists from the anal opening, which is similar in the case of automobile. Gasoline enters into the engine from the fuel tank and the waste product exit from the exhaust...

Summary Introduction

To determine:

The similarities between digestion in animals and breakdown of gasoline in an automobile.

Introduction:

Digestion is a process of breaking down larger food particles into smaller food particles. Digestion is of two types: mechanical and chemical digestion. Mechanical digestion is chewing of food in mouth and smooth muscle contraction in stomach, whereas chemical digestion involves hydrolysis of macromolecules into smaller particles. The food that is hydrolyzed is absorbed by the body and the waste is eliminated in the form of feces.

Students have asked these similar questions

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.
