Mutation

Mutations play a crucial role in genetic variation, which is fundamental to the process of evolution. These changes in the genetic material can have a range of effects: they may be harmful, leading to genetic disorders or cancer; beneficial, contributing to evolutionary adaptations; or neutral, having no noticeable impact on the organism.

Mutation

Mutation

Global warming is the ongoing rise of the average temperature of the Earth's climate system which has various negative effects.

5 Examples Of Disorders

Chromosomal Disorders
Turner Syndrome
Down syndrome
Single-Gene Disorders
Cystic Fibrosis
Sickle Cell Anemia

6 Genetic Variation

Overpopulation creates an increased demand for energy as well as having negative effects on our environment and ecosystems.

Sources Of Genetic Variation

Over-cultivation is the practice of excessive farming on a piece of land to the point of degradation of the soil as well as the land itself.

Fertilization
Independent Assortment
Recombination

7 Mechanisms Of DNA Repair

Climate change is likely to both increase electricity demand for cooling in the summer and decrease electricity, natural gas, heating oil, and wood demand for heating in the winter.

Recombinational Repair
Mismatch Repair

Finding reusable energy sources can be our first step towards conserving our environment.

Excision Repair

How will climate change affect the production of clean energy?

e.g.: solar, wind, water

Nucleotide Excision Repair
Base Excision Repair
Direct Repair

New infrastructure investments may be necessary to meet increased energy demand.

e.g.: nuclear power plants

3 Effects Of Mutation

Harmful Effects
Cancer
Genetic Disorders
Beneficial Effects

Climate change will affect mountain and lowland ecosystems, the diversity of wildlife, and the distribution of freshwater.

e.g.: forest fires

Evolutionary Adaptions
Neutral Effects

2 Causes Of Mutation

Healthy ecosystems and rich biodiversity are fundamental to life on our planet.

Even small changes in average temperatures can have a significant effect upon ecosystems.

Induced Mutations

The inter-connected nature of ecosystems means that the loss of species can have knock-on effects upon a range of ecosystem functions.

e.g. bees go extinct

Chemical Agents

Carcinogens

Mutagens

Physical Agents

X- Rays

UV Radiations

Spontaneous Mutations

Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favorable conditions.

e.g.: natural habitat disappearing

Natural Chemical Changes
DNA Replication Errors

1 Type Of Mutations

Climate change is supported by scientific evidence.
