Citrus2011 [14]

The burden of diseases A and B in country Z is that disease B has a higher prevalence than

disease A. That is option D.

<h3>Health statistics of Country Z</h3>

Health statistics is used by professionals to summarize the health status or information on the health of individuals in a particular geographical location.

The basic statistic tools that can be used to check the health status of a population are,

prevalence

Case fatality ratio

The prevalence rate is the total number of cases of a disease existing in a population divided by the total population.

The prevalence rate of disease A = 225 per 100,000 population while the prevalence rate of disease B = 500 per 100,000 population.

Therefore, the burden of diseases A and B in country Z is that Disease B has a higher prevalence than

disease A.

Answer:

D. The first flowering plants were introduced toward the end of the Mesozoic era.

Explanation:

Following the Paleozoic Era, the Mesozoic Era or Age of Conifers began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.

The Mesozoic era is marked by 3 divisions:

the Triassic Period,
the Jurassic Period,
and the Cretaceous Period.

Animals and plants slowly recovered after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.

By the end of the Mesozoic Era, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the Triassic, and the conifers, cycads and gymnosperms of the Jurassic.

Varied dispersal mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.
