Answer:
The correct answer is option C) "gastrovascular cavity".
Explanation:
Cnidarians are a large group of organisms, most of them found in aquatic environments, known for having specialized cells called cnidocytes which they use to capture their preys. Other characteristic feature of cnidarians is that they have a gastrovascular cavity that serves as the primary organ used for digestion. The gastrovascular cavity is usually surrounded by tentacles that serves to trap their preys. Examples of cnidarians include corals, hydras and jellyfishes.
Question: is plate-based or a meat-based diet is more nutritious
Answer: But it's also common to choose a plant-based diet because it's considered healthier. And that's for good reason. Research over many years has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers (as compared with diets high in meat and other animal products
Is a meat based diet better than a plant-based diet? Answer: Mounting evidence shows that reducing meat and increasing plant-based protein is a healthier way to go. A diet with any type of meat raises the risk of heart disease and cancer, when compared with a vegetarian diet.”
Plant-based diet: A plant-based diet or a plant-rich diet is a diet consisting mostly or entirely of plant-based foods. Plant-based foods are foods derived from plants with no animal-source foods or artificial ingredients. While a plant-based diet avoids or has limited animal products, it is not necessarily vegan.
Meat based diet:
Meat is a complete, high-quality protein containing all of the essential amino acids your body needs for optimal health.
Meat provides more protein per serving (25 grams per 3 ounces) than dairy (8 grams per cup), eggs (6 grams each), legumes (12 grams per ¾ cup), vegetables or nuts (2 to 5 grams per serving).
Minimal viable population, it's the least population an ecosystem can have of a species and not go through catastrophic events.

Hormones facilitate the type of adaptation to exercise, such as stimulating certain proteins for building muscle, or synthesising enzymes which improve the handling of glucose in a cell, and are crucial for endurance.

<u>Answer:</u>
<em>The type of object to be observed determines whether dissecting microscope or compound microscope should be used.
</em>
<u>Explanation:</u>
<em>A dissecting microscope is usually used to observe the surface features of a specimen and compound microscope</em> is used for an in-depth observation of the specimen.
The magnification of dissecting microscope is less than the magnification of compound microscope but dissecting microscope gives a three dimensional image of the specimen. <em>Another special feature of dissecting microscope is its long working distance.
</em>
Dissecting microscope uses the reflected light and thus preparation of specimen is usually not required. These features and its long working distance makes dissecting <em>microscope an excellent tool in forensic and scientific applications. </em>
Compound microscope can be used in situations when a high magnification is required. Looking through the <em>specimen is possible by the use of compound microscope. </em>
<em>Thus the type of specimen and in how much detail it should be examined determines the type of microscope chosen.
</em>
