Indirect methods like mark and recapture become a strong tool to estimate population size or density in species on which it is impossible to apply a direct methods. Because of their biological and ecological characteristics, the Gypsy moth and the Green lizard populations are good examples for which mark and recapture would work well.

------------------------------------------------------

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the Mark-Recapture technique.

The Mark-Recapture technique assumes that

the population is closed during the sampling season, there is no mortality nor natality,
marks in the individual last the whole sampling season, and they do not affect the marked individual or their behavior.
marked individuals are randomly distributed in the population, and
all the individuals have the same probability of being sampled.

The method consists of capturing a sample of individuals belonging to the population under study. After capturing the individuals, the researcher marks and releases them again. The third step is to sample again: The researcher captures new individuals and counts how many of them are marked. These marked individuals belong to the first sample.

Indirect methods like this become a strong tool to estimate population size or density in species on which it is impossible to apply a direct method such as counting individuals.

For instance, if we need to estimate insects population density (Gypsy moth population) or reptiles population density (Green lizard population) because of their biological and ecological characteristics, the best way of doing it is by applying indirect methods. These species characterize as small-sized, fast to escape, they can hide in small inaccessible places, they have nocturnal habits, their reproductive rate is too high, and their distribution rate is wide. Among many other characteristics, their population density can not be estimated by direct methods. Mark-Recapture technique is the most suitable one.

What factor prevents us from finding fossils from the precambrian era?

ad-work [718]

Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.

Semmy [17]

The nurse can give the client antidepressants such Duloxetine. Even though one is not depressed, one can still take this as this can also alleviate pain. Another medication the client can take is an anti seizure medication. An example of this is Pregabalin. It would prevent nerves from sending pain signals to the brain thus can also help ease the pain of a person suffering from Fibromyalgia.

As you stated before, cellulose is found throughout the cell walls of plant cells. Cellulose makes cell walls rigid, so that would indicate that cellulose is a carbohydrate.

Define the verb "adapt". Does survival in a particular environment through coping is synonymous with evolution? Why or why not?

notsponge [240]

Answer:

The word adapt means to get adjusted to a change.

yes, survival in a certain environment is similar to evolution. Both must use adaptation in order for life to keep living through changes in the environment. Each help life sustain itself in a very unique way.

According to one hypothesis, life on earth emerged from (bluegreen algae/ amino acids/ molten metals/ crustal rocks) in the pres

Yuri [45]

1) The answer is bluegreen algae

Bluegreen algae or cyanobacteria are thought to have started life on earth because they converted the atmosphere that didn't have a lot of oxygen, into an atosphere with enough oxygen to exist life. That oxygen was a product of their photosynthesis.

2) The answer is lightning.
By Primordial Soup Theory, life began as a result of the combination of chemicals from the atmosphere and lighning (a form of energy) to make amino acids. Aminoacids are necessary to build proteins, and proteins are necessary for all the organisms.
