Answer:
A, pleiotropy.
Explanation:
Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.
Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.
Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.
Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.

Answer: If the global warming trend continues and permafrost under the tundra melts, the biome that would you predict would replace it is:
Boreal Forest
Explanation: A boreal forest is a vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.
During an emergency what you would usually want to do is a so-called threat and hazard analysis - C.
You would do this because you would want to observe and note which is a source of threat for you in a certain emergency situation. You would also to this to observe the possible hazards of doing a certain action/certain actions.
Anterior, middle, and posterior
Answer:
adsorption, penetration, biosynthesis, maturation, release
Explanation:
The virus after infecting the cell produces several progenies which after reaching a certain number cause the lysis of the cell and are then released out from it. This process of entering the host by the virus and then lysing the cells to be released is termed as a lytic cycle.
There are 5 stages involved in this lytic cycle:
1. Adsorption - when the virus finds its attachment site on the bacteria it gets attached to the viral receptor and then is adsorbed on the bacteria, this is the first step required to gain entry into the host.
2. Penetration - once the virus is attached to the host the next step is to penetrate it and enter inside the cell. For this, the virus secretes lysozyme and then inserts its genetic material inside the cell.
3. Biosynthesis - this stage involves the utilization of the enzymes and nucleotides of the host to make up the DNA of the phage.
4. Maturation - once the phage DNA is made the next stage is to assemble the phage DNA with the capsid and this is termed as maturation.
5. Release - this step involves the breakage of the plasma membrane of the host cell and the release fo the phage particles.
