Answer:
A population of rattlesnake in the state of Florida.
Explanation:
A population refers to the group of individuals of a species present together in a defined region at the same time. All the members of a particular population belong the same species and hence, are able to interbreed to produce fertile progeny. Since they belong to same species, individuals of a population also share several common morphological traits.
Some of the attributes of a population are natality (the birth rate), mortality (the death rate), density (number of individuals per unit area), sex ratio, etc.
Therefore, the given example explains the population of the rattlesnake in the state of Florida.
Answer:
Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste.
Explanation:
Answer:
chiasmata
Explanation:
Chiasmata is the meeting point of homologous chromatids regarding meiotic cell division.
This structure conforms to homologous chromosomes when, in meiosis, part of the arm of each chromosome breaks and is recomposed into its homologous. This phenomenon, which is extremely important for evolution, is called chromosomal permutation or crossing-over. This phenomenon is associated with gene linkage, that is, linkage, which provides greater genetic variability and different gametic percentages than would be found according to Mendel's second law.
Based on this, we can conclude that the first suggestion that chromosomes could physically exchange segments came from the microscopic identification of chiasmata.
DNA code is doubled before being passed to new cells. Your answer would be C. Hope this helps! :)
