Explanation:
This is because a gamete will go fuse with another gamete and the sets of alleles from both will combine to form the required diploidy required for growth to a mature organism. If the gametes were diploid, then when two gametes fuse, the resulting zygote would be tetraploidy. Unless this is the natural ploidy for the organism – like in some plants – then the resulting zygote would not develop or the resulting mature organism would have abnormalities.
Answer:
Rhizobium is a bacterium that has positive effects on plant growth. Different strains display a wide range of effectiveness, from a little positive effect to a massive one. The strains used in the study did not show a positive effect promoting plant growth, so we could say that they ARE NOT Rhizobium strains and need to be properly identified.
Explanation:
C. The increase in average global temperatures caused by greenhouse gases
If you study biology, you should know that its goal is the study of life. So the answer is D.Measuring the rate of squirrel births in a woodland habitat
