Answer: Option A) 7
Explanation:
Taxa simply refers to the each category of classification used for biological purposes.
Thus, each taxon in the linnaen system of classification formed by Carolus Linnaeus are arranged as follows:
Kingdom --> phylum/division --> class --> order --> family --> genus --> species
Thus, they are they are seven (7) in total
Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
where a species lives is their habitat.
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
