A team led by evolutionary biologist Hopi Hoekstra set out to test the hypothesis that predators are an agent of natural selecti

on on mouse color. They made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. Complete a paragraph about two advantages and one disadvantage of using model mice instead of real mice in this experiment.

Answer:

One advantage of models is that all the mice are exactly alike except for color, enabling the control of all variables except the one being studied. Models are also easier to work with than live mice. One disadvantage of using models is that they do not have the same smell and behaviors as real mice.

Another advantage is that models can be reused for the experiment for a longer period of time with less maintenance.

Degger [83]

Answer:

Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.

alisha [4.7K]

PZ120 is not considered to be an enhancer to transcription in the metallothionein 2a gene.

<h3>About metallothionein 2A.</h3>

Metallothionein-2 is a metallothionein protein that in humans is encoded by the MT2A gene.

In human it is expressed in;

  • pericardium
  • right lobe of liver
  • olfactory bulb
  • left uterine tube
  • external globus pallidus
  • right lobe of thyroid gland
  • upper lobe of left lung
  • Region I of hippocampus proper
  • right lung
  • left lobe of thyroid gland

It's molecular function are;

  • Protein ion binding
  • Zinc ion binding
  • Metal ion binding

It helps in various biological processes;

  • response to metal ion
  • cellular response to interleukin-3
  • cellular response to erythropoietin
  • negative regulation of growth
  • cellular response to zinc ion
  • interferon-gamma-mediated signaling pathway
  • cellular copper ion homeostasis
  • cellular zinc ion homeostasis
  • detoxification of copper ion
  • cellular response to cadmium ion
  • cellular response to copper ion
  • nitric oxide mediated signal transduction
