Answer:
c) A study of how disease rates vary among different population groups
Explanation:
Epidemiology is the systematic and scientific study of the distribution of the health-related issue in a specified population.
The Epidemiologists studies the disease and its cause in a population by the collection of the data which gives an insight in the distribution of the health issues in the population living from a small area like school to a country.
The epidemiological studies help the society by reducing the risk of the negative health outcomes, in spreading awareness about the health issues and in framing the health policies.
Thus, Option-C is the correct answer.
Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.
The answer to your question is D. Heat Transfer
{I got this from online hope it helps}The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived. So yeah it’s true
