Avogadro tells us that we have 6.023 x 10^23 SiO2 units per gram, so there would be 6.023 x 10^23 / 60 ≈ 1 x 10^22 SiO2 units in a gram of pure SiO2, and with SiO2 composed of 3 atoms<span>, that puts us at </span>3<span> x 10^22 atoms per gram of SiO2. Now, a grain of sand does not weigh 1 gram. It weighs less</span>
Answer: Only Options A, C and E are correct
A) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
C) Sympatric speciation does not require geographic isolation.
E) Sympatric speciation can be due to sexual(mate) selection
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
> live in the same territory or nearby territories ( i.e not living in isolation)
> DO NOT interbreed, but select a sexual mate from a much diverse territory which results in an uneven gene flow or disruption of alleles among the population of same species of the parents organisms.
Answer: If you break the two terms down, "intraspecific" just means within a species, while "interspecific" means between them. Consequently, interspecific competition is all about competition between two or more species, while intraspecific competition involves different individuals of the same species.
Great question
The 3 domains are bacteria, archaea, and eukarya. The domain bacteria consists of the kingdom 'bacteria'. The domain archaea consists of the kingdom 'archaea.' The domain eukarya consists of the kingdoms 'plantae', 'animalia', 'fungi', and 'protista.'
