In a certain population, the two most heavily diagnosed diseases are schistosomiasis and malaria. over the past five years, mala

ria has accounted for more than half of all disease cases, and schistosomiasis, which accounted for 40% of all disease cases in the community five years ago, accounted for 30% in the past year.

According to the above statement, the conclusion is that if the total number of Schistosomiasis cases are increased over the past five years, then the total number of cases of this disease must have increased by more than 30%. Because five years ago the percentage of cases are 40% and the number of cases are 40/100, so the last year the number of cases of disease are 60. Total increase = 60/30 x 100 = 200, it means total cases which are increases 100% which is more than 30%.

creativ13 [48]

Answer:

A mutation in the DNA sequence of the gene for brown fur  

Explanation:

The mutations are capable of changing the encoded protein product, in this case the gene that encodes for the fur color pigment. This mutation may have occurred during mitosis or meiosis divisions.

If it is a spontaneous mutation that occurred in the germinal line (meiosis) and confers an adaptive advantage, it will increase their frequency in the population.

timofeeve [1]

The correct answer is: B) As land plants became more complex, animal life did as well.

This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.

So, plants were one of the earliest organisms to leave the water and colonize land.

Which part of your brain is essential for receiving information that you are moving your legs?
stealth61 [152]

Motor coretex is essential for receiving information that you are moving your legs.

<h3>What is motor cortex?</h3>
  • The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
  • The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
  • The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
  • For the execution of movements to be precise, coordinated muscle activation patterns are required.

Katarina [22]

Answer:

The Pepsi he drinks at 10 pm

Explanation:

Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
