Answer 1

Answer:

Georges Cuvier.

Explanation:

Georges Cuvier (1769-1832) fue un zoólogo quien propuso que la evolución era el resultado de extinciones producidas por catástrofes a las cuales les sucedían nuevas creaciones con distintas especies. Los ecosistemas con las catástrofes eran destrozados y en los suelos de estos quedaban los  restos de los animales extintos formando parte de los estratos de la tierra.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones

Answers

Answer:

Provides more strength.

Explanation:

It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.

Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation

Answers

Hope this helps :)))

C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.

How Natural disasters reduce population sizes?

Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.

Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.

Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.

On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.

Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.

Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.
