Summary Introduction

To explain: The mechanisms that might allow a species to maintain its characteristic distribution.

Introduction: There are three main ecological categories of organisms present in both fresh water and marine ecosystems. These are plankton, nekton, and benthos. The organisms that actively float on water are known as plankton. For example, fish, crabs, and sea stars.

Expert Solution & Answer

Explanation of Solution

The mechanisms that might allow a species to maintain its characteristic distribution are as follows:

  • The physical and chemical characteristics of water masses, such as temperature, nutrients, and salinity limit the horizontal or geographic distribution of plankton.
  • Gyre systems do not mix with surrounding masses. However, it shows little mixing with surrounding masses. In these masses and other masses, planktons are uniformly distributed.
  • Biotic factors such as limitations of food and predation may influence the patchy pattern of distribution.

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.
