Answer:
d. the groups will probably diverge genetically, and speciation may occur
Explanation:
The geographical isolation of two populations of a species for a longer time period leads to allopatric speciation. During the process, the isolated populations accumulate genetic variations to become adapted to the prevailing conditions of the habitat.
Accumulation of genetic variations leads to reproductive isolation between the population. After several generations, the individuals of the two isolated populations are unable to interbreed due to genetic variations. Now, these two populations are said to belong to two different species. The isolated lizard populations would also accumulate genetic variations resulting in allopatric speciation.
Prions are infectious agents that are made up of proteins which can fold in multiple ways. The three dimensional folding shape of a prion is determined by folding and intra molecular bonding of the linear amino acid chain. The folding and the intra molecular bonding on the other hand is determined by the amino acid sequence in the prion.
Answer:
<em>Reversed polarity</em> is when the hot and neutral connections at a receptacle are wired backwards/inverse—Home wiring is color-coded, and the black wire is “hot,” meaning that it is electrically charged or, as it is sometimes called, the “live” wire!
Answer:
The most appropriate answer would be the first option.
Adaptive immunity is a part of the immune system which protects our body against infectious agents with the help of B lymphocytes and T lymphocytes.
It is characterized by its memory that is, it creates the memory of a lifetime for particular antigen or pathogen once it has come across.
As Adrian caught the virus a few years ago his immune system had developed a memory for the virus.
So, as soon as his body contracted the same virus his body recognizes it easily and produce quicker and higher amplitude immune response against it.
Answer:
After fertilization, a single cell divides successfully to form a multicellular structure. What happens next in order for this structure to develop tissues and organs to meet the needs of the organism? The cells undergo differentiation into particular body parts.
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).
