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:
You drove through Iowa in the spring and noticed that along a stretch of several kilometers, every third fence post had a male red-winged blackbird perched on it defending its nesting territory. This is an example of <u>uniform dispersion.</u>
Explanation:
There are usually three dispersion patterns :
- Clumping
- Uniform dispersion
- Random dispersion
Clumping is the most common.
Uniform dispersion occurs when
- resources are scarce
- Individuals are evenly spaced in a habitat
- Due to competition or territorial behavior
While Random dispersion occurs when resources are plentiful.
Hence ,This is an example of <u>uniform dispersion.</u>
Answer:
B. Habitat
Explanation:
Habitat destruction is the process by which natural habitat is damaged or destroyed to such an extent that it no longer is capable of supporting the species and ecological communities that naturally occur there. It often results in the extinction of species and, as a result, the loss of biodiversity.
