Answer:
the characteristic of vertebrates from the following is
This is known as Pancytopenia.
The three hematopoietic cell lines lead to the formation of red blood cells, white blood cells and platelets. All these cells play important roles in various body functions.
Pancytopenia is a condition in which the quantity of red blood cells, white blood cells and platelets decrease in the body of a person. Chemotherapy and radiation are serious procedures that along with killing the cancerous cells also destroy many of the normal cells of the body. Hence, chemotherapy and radiation leads to decrease in all the three hematopoietic cell lines of the body causing a condition referred to as Pancytopenia.

Answer:
Evolution or Adaptation
Explanation:
Because of the available food in the environment, such as big or small, hard or soft seeds based on the weather and the plant's production, the birds have to adapt to be able to consume their new type of food available, if a bird with a small beak tried to eat a large hard seed, it wouldn't be able to, or if a bird with a big beak tried to eat a small seed, it probably wouldn't be enough
Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
