C. Australia was covered in ice during a key geologic period.
at the time of coal forming, Australia was closest to the south pole, so it was too cold.
<span>Matter is recycled within and between ecosystems through biogeochemical cycles.

Answer:
f(A1) = 0.9700, f(A2) = 0.0300
Explanation:
The frequency of homozygous recessive genotype of children is
As per Hardy weinberg's equation, frequency of homozygous recessive genotype is represented by
Here 
Thus, frequency of recessive allele would be
as per first law of Hardy weinberg
Hence, option C is correct
Answer:
(a) <u>16</u> % of the alien genome is comprised of G.
(b) 17% of the alien genome is comprised of T.
(c) 17% of the alien genome is comprised of A.
(d) <u>22</u> % of the alien genome is comprised of X.
Explanation:
Assuming the alien follows Chargaff's rules which states that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases.
So if:
16% contains C ; 16 % pairs with G = 32% C-G pairing.
22% contains Y ; 22 % pairs with X = 44% X-Y pairing.
44% G-C + 32% X-Y = 76%
100%-76% = 34% the remaining should be split between T and A which is 17% each one.
Answer:
C. nucleus
Explanation:
Karyon is a Greek word which means a kernel or nut and it depicts organisms that do not have a true nucleus. The shape of the nucleus was used in giving it the name karyon.
Prokaryotes are organisms that lacks a true nucleus and do not have membrane bound organelles.
Eukaryotes on the other hand have true nucleus with membrane organelles.
