The correct answer is C - carbon dioxide.
The distribution of gases in the earth's atmosphere is as follows:
1. Nitrogen - 78 %
2. Oxygen - 21 %
3. Argon - 0.93 %
4. Carbon dioxide - 0.038%
Nitrogen, oxygen and argon are permanent gases whose percentage in the atmosphere does not change from day to day.
Gases such as carbon dioxide, nitrous oxides, methane, and ozone are known as trace gases which make up 0.1% of the atmosphere.
I think it's false. For example, when tectonic plates shift/meet, it causes an earthquake. Earthquakes can cause serious damage, (like trees falling, water ending up where it shouldn't be, animals' habitats being disturbed, etc.), so I would say that it's false that the climate is not directly effected by the movement of tectonic plates because it effects it greatly. Hope I helped! :)
Answer:
The answer is Eurasia, North America, Africa, and South America.
Explanation:
False. Interphase is not technically a part of mitosis.
During interphase, the cell is performing its normal functions and preparing for mitosis.
Answer:
The proportion of the genotypic recombinants among the offspring from this cross is 75%
Explanation:
Separating the alleles from the parents independently, We have AB, Ab, aB, and ab.
These should be crossed using punnet's square, we will therefore get the genotypic of the 16 progenies as: AABB, AABb, AaBB, AABb, AAbb, AaBb, AaBB, AaBb, aaBB, AaBb, Aabb, aaBb, aabb, aaBb, Aaaa and AaBb. From these, only those in bold retained the genotype of their heterozygous parents. Therefore, 12 out of 16 are genetic recombinant, which are the offspring that differs from their parents after a cross. This made the proportion to be 12/16 X 100 = 75%.
