Expected prevalence of a disease is:______.
goldfiish [28.3K]

Answer: c) the anticipated geographical spread of a disease based on past observances.

Explanation: Prevalence simply means the widespread of a thing or condition. In epidemiology, prevalence can be defined as the total number of people in a population that is affected by a medical condition or total number of cases of a disease in a population in a given period of time.

Expected prevalence of a disease is therefore the anticipated widespread of a disease or the anticipated total number of cases of a disease in a population based on past observed incidences.

someone please help me with Part A and B on biology please i really need help will give brainliest ​read hard and rotate phone i
finlep [7]

<em>Hi there, I come in behalf of jcherry99,</em>

So, first question -

This shouldn't be that much of an issue, since we have the text to help us out, but I'll try breaking it up into more simpler words:

The placenta is incide the uterus, where the baby starts forming. As you might already know, babies do not eat while they're inside woman's bellies:

So how do they feed?

They feed throught the umbilical cord.

So why is the placenta there? Why would the baby want anything apart from food?

The placenta, instead of trading food with the baby, regulates temperature, supplies it with nutrients, exchanges gas with the mother (which the mother later exchanges with the environment) and gets rid of waste.

And, food is not everything for a baby that is in the urge of developing complex muscles, bones, etc.

Second "question" -

I do not actually know what I'm supposed to do, since there is no question. But I can tell you this - the information contained in part B is correct:

The amnioic sac provides babies with a liquid which allows him to move freely in the uterus, which is very helpful. But, note that he doesn't start moving randomly, he is always in a fetus or similar-to-fetus position.

Hope it helped,

slava [35]

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
