The answer is A. An electrocardiogram (EEG) measures the electrical activity of the heart to see if there’s any irregularities in the heartbeat. Irregularities in your heartbeats can be caused by many things including blockages which can cause strokes and heart attacks. It’s a good idea for students or any athletes to get an EEG as part of their physicals to rule out any heart issues.
Answer:
The correct answer is C) gene flow
Explanation:
The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.
Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.
Therefore the primary criteria for determining species boundaries is gene flow.
Fat is less soluble in water compared to phospholipids.
This is because, fat is made up of three molecules of fatty acids which are not polar in nature at all, thus they mixed very poorly with water.
Phospholipids on the other hand has its molecules divided into two distinct regions, the head and the tail region. The head region is hydrophillic and it is polar in nature, that is, it mixes well with water. The tail region is made up of the fatty components and it is hydrophobic.
Because of this difference in structure, phospholipid will dissolve better in water.
