Answer:
The given statement is false.
Explanation:
In ecology, one of the means of measuring diversity is Simpson's Diversity Index. This index is generally used to count the biodiversity of a habitat. The index considers the number of the present species, and at the same time each species' abundance.
Simpson's index denoted by D determines the possibility that two characters selected abruptly from a sample will fit to a similar species or some classification other than species. When the value of D is 0, it signifies infinite diversity, while when the value is 1 it denotes no diversity. Thus, the bigger the value the lower will be the diversity.
Answer:
The genotype is the part of the genetic makeup of a cell, and therefore of any individual, which determines one of its characteristics.

Its 18 electron
1st orbital : maximum = 2 electrons
2nd orbital : maximum = 8 electrons
3rd orbital : maximum = 8 electrons

Complete question:
Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:
Answer:
The lynx and the wolf are the only secondary consumers on the list.
Explanation:
In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.
The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.
The following links are the consumers: herbivores are primary consumers and feed on producers. <u>Carnivores are secondary consumers and feed on herbivores</u>, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.
On the other hand, the moose and the elk, are both first consumers.
Answer:
Miasma theory was replaced because John Snow collected data that showed that germs cause disease.
Explanation:
The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.
John Snow, an english physician, was one of the main contributors to the <u>microbial theory of disease</u>. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This <u>data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease</u>.
