Ans.
In flowering plants, the male reproductive part or stamen is made up of a stack-like structure, known as filament and an ovule-like structure, known as anther. In anthers, microsporangia are present that produce pollen through mitosis.
Thus, 'if anthers are removed from a flower, it will not be able to form seeds as seeds are developed from zygote, that forms by the fusion of male gamete (pollen) and female gamete (ovum).'
Answer:The closer a location is to the equator, the more energy it receives from the sun. Therefore, a location's air temperature is affected by its distance from the equator. The amount of energy from the Sun does not change during El Niño years so there must be some other cause for cooling in New Zealand
Explanation:
Answer:
A. The gene for surface protein was transcribed and translated.
Explanation:
Because all living organisms use the same genetic code, it is possible to express genes from one organism in the other. In this case, the DNA sequence that corresponds to the hepatitis B surface protein gene has been inserted into the banana, and the protein is expressed.
For the protein to be expressed, the gene must have been successfully transcribed into an mRNA by the banana plant machinery. This mRNA has then been translated into a protein that means the hepatitis B surface protein is now present in the cell.
