The publication that described above change asteroid impact hypothesis into a scientific theory that is “set in stone”. Introduction: The scientific theory is defined as a well-sustained explanation at some features of natural world. It is based on the fact which is confirmed so many times a series of observations and experiment.

Question

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?

The cause of K-T extinction ever be proven.

Introduction:

The Cretaceous-Tertiary extinction or K-T event involves die-off of dinosaurs and other animal species. They were died over 65.5 million years ago. The organisms died due to climacteric and other geological changes.

Summary Introduction

To determine:

The scientists believed that evidence pointed to alternative causes for extinction now abandons their hypotheses on this article.

Introduction:

Extinction is defined as the biological process of termination of organisms or group of organisms from a population over a period of time. Extinction occurs due to several different factors such as environmental and geological conditions.

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.
