Answer:
E) virus
Explanation:
<em>The description is a case of an attack by a virus known as 'baculovirus'.</em>
When a caterpillar is attacked by this virus, it gradually takes over the caterpillar's body system and programs the sick organism to move towards light which is usually the top of the plant.
Apart from the fact that the virus takes over the body of the caterpillar, it also triggers the body of the organism to melt, thus rupturing into liquid-like substance when touched.
The correct option is E.
The answer is C. kudzu, zebra mussels, and brown tree snakes are all invasive and caused harm to the environment they were introduced to one way or another.
The principles of probability can be used to predict the outcomes of genetic crosse
Answer:
-100
Explanation:
If the total water potential in the soil around a plant root were -50 kPa, water would move from the soil into the root if the water potential inside the root cells were -100 kPa.
The water potential of a substance represents the measure of potential energy in water molecules in a system as compared to that of pure water. It is also a measure of the tendency of water to move from one region to another.
<em>Usually, water will move from the region of high water potential to the region of low water potential. Hence, for water to move from the soil into the root, the root must have a lower water potential than the soil.</em>
The soil had -50 kPa water potential, hence the only option that is lower than -50 kPa is -100.
The correct answer is -100 kPa.
Answer;
Not get any isolated colonies
Explanation;
-An isolated colony of bacteria is the progeny of a single bacterial cell. An isolated colony represents a pure source of an organism from which a pure culture can be started.The idea behind streaking for single bacterial colonies has to do with purity.
-When you have a single colony isolated from the rest of the colonies on the plate, it is a pure colony “grown up” from a single bacterium (that was isolated from the rest of the sample, streaked out on the plate).
