Climate change causes changes in weather conditions over a long period of time.
<h3>What is climate change?</h3>
Climate change refers to those long time changes in the weather condition of a place.
The heat from current climate change ultimately comes from energy from the sun, trapped by carbon dioxide in the atmosphere.
As the earth's temperature increases, the processes on earth are affected such as increased precipitation and increased sea levels.
An example of a positive feedback loop is;
- Temperatures rising cause ice and snow to melt, which causes more heat to be absorbed by the ground, causing temperatures to rise more.
- Melting ice causes more sunlight to be reflected into the atmosphere, causing the temperatures on Earth to increase, which then causes more ice to melt.
The most effective way for an individual to reduce climate change on individual basis is to turn off the lights after leaving rooms.

Answer:
Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.
For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.
Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).
Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.
For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1
Answer:
B
Explanation:
Adaptation can be described as a process that helps the organisms fit their environment and enhancing their evolutionary fitness (reproductive success). Adaptation makes organism become well-suited for an environment and thus, help them to survive and produce more offspring. Also, adaptation may refer to a phenotypic or adaptive trait with a functional role in the success of each organism in their habitat.
They increase the genetic diversity of the species
Answer:
Rubella.
Explanation:
German measles is a viral infection that causes red rashes on the whole body of an infected person. The disease can be easily spread from infected people to healthy people by sneezing or coughing.
The German measles is caused by rubella virus.Rubella virus contains single stranded DNA as its genetic material. Rubella virus causes fever and swollen lymph nodes in infected individuals.
Thus, the correct answer is rubella virus.
