The process of sexual reproduction includes fusion of female and male gametes coming from both the parents. In the process of sexual reproduction, a new individual is produced due to the combination of two haploid gametes, one from the female parent, and the other coming from the male parent.
The importance of sexual reproduction:
1. The joining of DNA from two distinct individuals results in the increase in the genetic variation in the offspring.
2. This further results in diversity in the population that assists in natural selection.
<u>Answer</u>:
C. Winds carry air pollution across oceans and continents.
Planet Earth has complex global wind and air current systems. Thus, air pollution produced in one place, will never remain there for ever. It some cases, due to wind patterns, the majority of the pollution may be carried away to some other place on the globe. This is why US should be concerned about air pollution in China. Even if the distance between the two countries is signinificant, it does not mean that US will remain unaffected by China's activity.
Answer:
Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.
A single gram of carbs provides about four calories of energy. 15 grams per 2.2 pounds.
I think 20 because
2n=20
n=20/2
N= 10
And chromosomes replicate themselves during interphase so the answer is 20.
