How can knowing if an organism is a prokaryote or eukaryote assist in classification?
Answer: Similarities, Differences and Organelles. Literally meaning to possess a “true nucleus," eukaryotes consist of animals and plants. Clearly seen under a microscope, the enclosed nucleus separates these cells from prokaryotes; in addition, eukaryotic cells also contain organelles.
Explanation:
Knowing that an organism is a prokaryote or an eukaryote will assist in its classification because prokaryotes and eukaryotes belong to separate domains with distinct characteristics.
Prokaryotes are organisms whose cells are microscopic, primitive, and lack nucleus and membrane bound organelles. They are divided into 2 sub-domains:
ArchaeaBacteriaEukaryotes, on the other hand, are organisms whose cells are more complex with nucleus and membrane-bound organelles. They are divided into 4 sub-domains or kingdoms:

By simply eating a banana, a child could be protected against disease without getting a shot!
What would you do?
A. Encourage your patients to eat genetically modified fruits and vegetables
B. Continue to use the vaccinations despite the cost
Answer:
A
Explanation:
is the answer cuz just by eating a banana the disease can be prevented
Encouraging patients to eat genetically modified fruits and vegetables which protect them from getting sick. So, the correct option is (A).
What is Genetically Modified food?
Genetically modified foods are also known as GM foods or genetically engineered foods or bioengineered foods. These are produced from organisms whose DNA has been altered using genetic engineering methods.
These are derived from organisms whose genetic material (DNA) which has been modified in a way which does not occur naturally, e.g. through the introduction of genes from a different organism.
There are several benefits of GM foods in agriculture like
1. Increased crop yields
2. Reduced costs for food or drug production
3. Reduced need for pesticides
4. Enhanced nutrient composition and food quality,
Thus, encouraging patients to eat genetically modified fruits and vegetables which protect them from getting sick. So, the correct option is (A).

What are two ways that a frog’s tongue is different from a human’s?
Which of the following might restrict the growth of a population?
O Mild winters
O Increased predation
o Increased numbers of prey
O Ample rainfall
30 POINTS!!!!
Answer: Increased predation, and mild winters.
Explanation: As the prey population increases, there is more food for predators. So, as the number of predators increases, more prey are captured.
Mild winters would cause all of the plants to die, therefore prey would also die due to lack of food and cause predators to die as well for the same reason.
Side note: It might also be ample rainfall but I didn't know if they meant ample rainfall as in flooding or not, if it means flooding then that could be an answer, too. And I also wasn't sure if this was multiple choice or not.
Good luck! :)
