In terms of cells the answer is ribosomes
Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies
.
Sampling - Done by counting the animals in a small area and then estimating how many are in the larger area. You go out and take samples from different places so you can take the average. In most cases, it is not possible to count every member of a population so an estimate is made.
Mark and recapture - Another estimating method is a technique called "mark and recapture." This technique gets its name because some animals are first captured, marked, and released into the environment. Then another group of animals is captured. The number of marked animals in this second group indicates the population size.
Indirect observation - The members of a population may be small or hard to find. It may be easier to observe their tracks or other signs rather than the organisms themselves.
Direct observation - The most obvious way to determine the size of a population is to count, one by one.
Answer:
This is known as <u>a density-independent limiting factor</u>
Explanation:
Answer:
Dogs smell a lot better than humans, because they have more complex nose structures that allow them to follow any scent
Answer:
Mushrooms with gills, typically available in supermarkets, have meiotically produced spores located in or on BASIDIA and belong to the phylum BASIDIOMYCOTA.
Explanation:
Mushrooms are fruiting bodies of certain fungi that belongs yo the phylum BASIDIOMYCOTA. They are incapable of producing their own foods( because of lack of chlorophyl) therefore are saprophytic in nature. It derives its nutrients for growth from metabolizing non living organic matter.The structure that you normally see above the ground is the part of the mushroom that is producing and dispersing spores which is located at the BASIDIA.
Mushroom are used for different purposes:
- the edible species are useful in cooking since it provides vitamin D to the diet.
- it's extracts can be used for medical purposes.
