Answer:
The correct answer is: Genetic Drift.
Explanation:
- In any population of any species having two or more alleles encoding for different genes, the frequency of occurrence of each allele among the individuals of a population can vary.
- The frequency of one allele may be far more or far less than the frequency of other alleles.
- The frequency of any particular allele is dependent on factors like random mating among individuals as well as natural selection, that tends to increase the frequency of those alleles which provide a survival advantage to the individual in a given environment.
- Genetic drift can be defined as a phenomenon due to which the frequency of an allele encoding for a particular gene undergoes drastic change (increase or decrease) in a population due to random mating as well as natural selection.
- In the given statement, one individual of an isolated population of piranhas underwent synonymous mutation in the beta-globin encoding gene.
- A synonymous mutation can be defined as such a change in the nucleotide sequence of a gene that does not affect the sequence, structure or function of the protein encoded by it.
- The increase in the frequency of the mutated form of the beta-globin gene after five generations to 5% indicates that due to the impact of random mating or natural selection or both, this has happened.
The blood cell will lose water and will undergo lysis.
Cell membrane is permeable to water and can get/lose water via osmosis. Osmosis is induced by the gradient of concentration of the solution. In this case, the 10M salt solution has a very high oncotic pressure that it will attract nearby water. That means the water inside the cells will be taken into the solution and cell will continue to shrink and then die.
Answer:
Global Warming is simply the long-term rise in temperature of the Earth's core, which inevitably would effect the climate systems of the Earth.
The Green House Effect is the natural process that warms the Earths surface.
Explanation:
The Green House Effect--> When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back into space and the rest is absorbed and re-radiated by the greenhouse gases.
