Population extinction is a natural occurrence, but because the pace of extinction on a global scale is increasing, understanding extinction is crucial for conservation. To evaluate proposed extinction processes, the rate of extinction in experimental populations of brine shrimp (Artemia franciscana) was evaluated. As was predicted, the chance of extinction was decreased by a larger initial population, a larger maximum population size supported by the environment, and less change in environmental variables. However, contrary to popular belief, maximum population size and environmental variation were more significant than initial population size. Unexpectedly, the importance of deterministic population oscillations brought on by inborn nonlinear dynamics and overcrowding was equal to or greater than that of the assumed processes.

<h3>What is extinction?</h3>

Extinction happens when species become endangered due to environmental factors such habitat loss, climate change, natural disasters, human overuse, and pollution, or because of evolutionary changes in its constituent parts.

Answer:

Mendel's law of independent assortment

Explanation:

Gregor Mendel is a really important figure in genetics, his work on pea plants provided us with many of the fundamentals of genetics that we still have today!

Mendel proposed 3 laws:

1. The law of dominance - this law states that where there are two different alleles (heterozygous) the organism will always express the dominant trait over the recessive trait

2. The law of segregation - this law states that offspring will inherit one allele from each parent, because allele pairs separate in the process of meiosis, such that each gamete contains 1 allele of each trait. When the zygote is formed, it contains an allele from each parent.

3. The law of independent assortment - this law states that traits are independent from one another at the time of gamete formation. The genes are segregated separately from one another, as the presence of one does not impact the presence of another.

This example shows that all combinations of the height and color allele are possible, and therefore nicely demonstrates the law of independent assortment

Paul [167]

False, an environment containing no calcium is not the best for Brian shrimp egg hatching. The following evidence statements can be used to support our answer.

  1. Control shows 9 hatchlings after 72 hours whereas the treatment of 10mg/100ml concentration of calcium shows 17 hatchlings.
  2. Control shows 9 hatchlings after 72 hours whereas the treatment of 20mg/100ml concentration of calcium shows 28 hatchlings.
  3. Control shows 9 hatchlings after 72 hours whereas the treatment of 10mg/100ml concentration of calcium shows 39 hatchlings.
