Oceans often get oil and toxic waste dumped into them as a bit of a "cheat" to cheaply dispose of waste. This harms the ocean life greatly. A leading cause of dumping into the oceans is the expense of getting rid of used oil. If a city were to allow residents to dispose of these things at no cost to them, there would be no need for people to dump it into the ocean. This will reduce the harm to sea life.
That is known as a tumor. Or cancer
Sample b is the control group because it’s the group not being tested and being kept the same.
Answer:
B, they share similar chemical properties.
Explanation:
- The environment needs to change in order to natural selection to occur.
Reason:
Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2. Population has some genetic variations.
Reason:
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:
mutation and random mating between organisms
3. Nature select organism with specific traits to survive and reproduce.
Reason:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
