Answer:
The potential risks associated with plant-based pharmaceuticals include: pollen transfer to related species, contamination of non-transgenic crops intended for the consumption by humans, allergic reactions to the drugs produced from the genetically engineered plant, and persistence of genetically engineered material to persist in the environment and accumulate in non-target organisms. Risk assessment of plant-made pharmaceuticals should be reviewed on a case-by-case basis because the plants used to produce proteins each have different risks associated with them.
Answer:
Species separated by a physical barrier for a long time, suffer allopatric speciation, so they can not interbreed anymore.
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flow, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Vicariance is the geographical separation of an original population into two or more new groups. Discontinuities in the physical environment like rivers, mountains, water, etc., are physical barriers that impede genetic flow between the separated groups.
The process of allopatric speciation involves different steps:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Answer:
is always a higher organism
Explanation:
lets take an example:
food chain consisting of zooplankton, small fish, big fish and man
as the order goes in the question ,the organism at the end of this food chain is man
Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).
