Answer: 1. 0.6 m/sec. 2. 6m/sec
Explanation:
Frequency = 0.1/sec wavelength = 6 m
speed = freq x wavelength = 0.6 m/sec
speed = distance/time = 60/10 = 6m/sec
Hi
<span>Firstly, the white blood cells tend to have a higher surface to volume ratio then other cells because the are more amorphous. That would lead to an relative increase in plasma membrane, which contains receptors for identifying antigens. Thats why, the white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration. It's basically because this.</span>
<span>linnaen classification was 2 kingdom classification,named plantae and animalia, on the basis of nutrition w.h.whittaker included 5 kingdom classification monera,protista,fungi,plantae,animalia.
so option b)plant and animal kingdom is right,
actually linnaeus put all protists,monerans,and plants in one kingdom plantae,though they have different cell structure,and mode of nutrition.</span>
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
