Answer: A vacuole undergoes a change in the plant causing wilting and droping.
Explanation:
The vacuole is an organelle, which is a store house of excess water and stored materials. During dehydration, the plant uses water from vacuole. Thus water and stored materials reservoirs get consumed up in this process, the plant experiences scarcity of water. This causes wilting and droping of plant.
The cell membrane is an envelop outside the cells, which causes plants to maintain their structure during stress for example, plant exposed to hypertonic solution. This prevents the cells to burst.
A virus require a living host. A host can be a plant, animal, human, or any other living organism. It does not have a cellular machinery thus uses host cell machinery to replicate its genetic material and produce its progeny.
The scientific method is a list of steps that scientists use all the time. Scientists use the scientific method to answer questions about certain things and ask questions.
Steps of scientific method:
-Question/problem
-Research
-Hypothesis
-Test/experiment
-Analyze results
-Draw conclusions based on evidence
During meiosis, independent assortment and crossing over of DNA segments result in gametes with diverse sets of genes. Additionally, random fertilization of an egg by a sperm occurs, forming a zygote with unique genetic material from each parent.

Answer:
Adult anteaters compete for food and many young anteaters die
Explanation:
As there are not many predators and the number of ants is abundant, the population of anteaters should grow on a large scale, however, this is not what happens, since the size of the population is the same for twenty years. This shows that the anteater population itself is regulating the size of the population through internal disputes, where anteaters, due to the high birth rate, end up competing for food and shelter, causing the most young and inexperienced individuals to be killed.
