It is student A .
It contains the study of plants and soil
Answer:
After every 0.192 centimorgan
Explanation:
If there are 125 million base pairs then according to the parallel ratio compare rule it should contain an average of 650 genes. If every gene has to be marked by a single marker on each end then a total number of 651 markers are used after every 0.192 centimorgan distance.
Cells with the full set of chromosomes are
diploid somatic cells.
Answer:
Strawberries and raspberries aren't really berries in the botanical sense. They are derived from a single flower with more than one ovary, making them an aggregate fruit. True berries are simple fruits stemming from one flower with one ovary and typically have several seeds.
Answer:
The phenomenon through which certain pollutants (harmful chemicals) get accumulated in tissues of organisms at different trophic levels in increasing concentrations along the food chain, is called Biomagnification.
Explanation:
1)Suppose, DDT is being used in a farmland.
2)There's a water body nearby the farmland and the water is contaminated with the DDT(let's say the quantity: 0.003 ppb).
3)Now the aquatic organisms (Zooplankton) which consume this water also consuming the DDT also.(0.04 ppm)
4)Next these Zooplanktons are consumed by small fishes. (0.5 ppm)
5)These small fishes are then consumed by Large fishes. (2 ppm)
6)These Large Fishes are consumed by Humans or Birds afterwards. (25 ppm)
7) So at each step DDT is also getting accumulated and at each successive trophic level the quantity of Accumulated DDT gets magnified as the organisms on higher trophic levels consume more biomass than the previous ones. This is a classical example of Biomagnification.
