Answer:
B. very high genetic variation
Explanation:
Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.
This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.
Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.
1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.
2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.
3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.
4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.
Eye color and ear shape are inherited.
Body height is mainly inherited/ influenced.
Species cannot be changed? So my guess is that C. Is the correct answer as it is not a inherited trait.
If that is wrong, then the answer is D. Because I would think body height is influenced by the two parents.
Answer:
apex refers to the highest point or vertex of a plant stem or root. The shoot apex is where fresh stems, leaves, and other parts of a plant grow after the old parts fall off or dry up.
Explanation:In experiments conducted plants with the apex grows and its height increase while the height of the plant without the apex does not change.In another experiment plant with the apex grows towards the direction of sunlight which is positive phototropic movement and the plant without the apex does not turn towards light.therefore we can conclude there is an effect of the apex on the growth of a plant.
A seed of a flowering plant or gymnosperm may contain tissues from three generations. Similar to gymnosperms, angiosperms also are seed producing plants, but are distinguished from gymnosperms by features such as flowers, endosperm within the seeds, and the production of fruits that contain the seeds.
