The correct answer to this question would be:
The microorganisms that make up the
normal human flora are important for <u>“preventing the colonization and multiplication of pathogens”.</u>
The human flora or human microbiota is
the totality of microorganisms which resides on or within our body. The normal flora of humans is composed of a few
eukaryotic fungi and protists, but bacteria are the most abundant and obvious
microbial components of the normal flora. The microorganisms of the
normal flora help the body fights against the pathogens by challenging for
microenvironments more effectively than such pathogens or by supplying
nutrients the body can use.
Answer:
scientific consensus changed as scientists learned more about organisms.
Explanation:
The classification system for organisms has changed from seven levels to eight level of classification system because scientists learned more about organisms. This new learned information allow scientists to change the existing classification system. When the scientist find new species that may have to change classification systems in order to accommodate them and placed them accurately in the classification system.
Answer:
In sexual reproduction, two parents are required to produce a new organism. Most plants and animals, including human beings, reproduce sexually
2. the production of new organism by combining genetic information from two individuals of different types (sexes). in most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by others (female).
To solve this problem we first need to find the amount of gametes a fruit fly produces in a meiotic division. For this we will use the formula 
, where n represents the number of gene pairs. In our case then, 
= 2.2.2.2 = 16
So a fly produces 16 different combinations of gametes. If this fly crosses another one, we have a universe of possibilities of combinations given by the multiplication of the male and female gametes. In the case, then, it would be 16 x 16.
16 x 16 = 256
The answer would be D
polar ice caps melting would result in cities on the ocean having an even higher chance of flooding due to the increase in the sea level
