Penicillins are a group of antibiotics, so penicillin is able to kill bacteria. Still, some bacteria produce a chemical to be resistant to penicillin, which mean that those bacteria can survive exposure to penicillin.
If one of those bacteria reproduce asexually, its reproduction depends only on itself, and the offspring will be identical to the parent, becaus in asexual reproduction there is no combination of gametes to form a different offspring.
So the offspring will have the same ability as the parent, being able to survive exposure to penicillin.
Therefore, the correct answer is D. Survive exposure to penicillin.
The answer is true, i just took the test.
1) B
(I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition
2) D
Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.
3) A
4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.
<u>Answer:</u>
<h2>
Osmosis</h2>
<u>Explanation:</u>
<u />
The movement of water across the semipermeable membrane is called osmosis.
The semipermeable or selectively permeable membrane allows only certain solutes to pass through the membranes and hinders other solutes. The water level is the same, but the concentration of the solutes is different on both sides of the membrane. So this passive transport of the water occurs to balance the concentration of solutes on both sides of the membrane.
Answer:
C) P wave
Explanation:
Sleep apnea can be described as a potentially serious sleep disorder in which breathing repeatedly stops and starts.
The Obstructive sleep apnea is a type or example of sleep apnea in which an individual can't breathe normally because of upper airway obstruction during sleep. This obstruction could be complete or partial obstructions.
It should be understood that, an echocardiogram uses sound waves to produce images of your heart.
In this case, the P wave portion of the electrocardiogram will be abnormal. This is because, the P wave is the result of atrial depolarization and would therefore have changes associated with atrial enlargement.
