Answer:
2.are ectotherms
4. lay eggs
5. have a three-chambered heart
Explanation:
they my corrected answers
The answer would be –genesis and –gram.
Suffixes that have a Greek or Latin roots and that are used
to combine with other words or parts of words are not called suffixes, these
kind of affixes are called combining forms.
One combing form is –genesis.
As an independent medical term, this means the origin of
something in medicine. When a doctor talks about the genesis of a contagion, he
or she is speaking of the point of origin of a contagion.
-genesis used as a suffix, can indicate a particular process
or pathogen. Example is parthenogenesis.
One combining form is –gram.
As an independent medical term, gram indicated the metric
weight of an object as a unit of mass. If nurses talk about how much serving of
food, they are talking about it in grams.
-gram signifies something written down. Example is
pictogram.
Answer:
If we continue to increase greenhouse emissions, more of it will build up in the atmosphere, meaning more of the Sun's infrared radiation will be trapped via the Greenhouse Effect. This will cause the planet to warm.
The correct answer would be the nucleus.
Hope this helped :)
Answer:
Allele frequency
Normal allele 
Mutant r allele 
Genotype frequency
Homozygous normal bugs 
Homozygous mutant bug 
Heterozygous normal bug with one mutant r allele and one normal allele 
Explanation:
It is given that 99% of the bugs were killed after the spray of pyrethrum. This suggests that 1% of the bugs that were not killed must be homozygous for the mutant type allele "r"
Thus, the frequency of homozygous "rr" species i.e 
From this we can evaluate the frequency of mutant "r" allele.
Thus, 

As per Hardy-Weinberg first equilibrium equation, 
Substituting the value of q in above equation, we get

Thus, the frequency of homozygous normal bug is equal to

As per Hardy-Weinberg second equilibrium equation-

Substituting all the available values we get -

Allele frequency
Normal allele 
Mutant r allele 
Genotype frequency
Homozygous normal bugs 
Homozygous mutant bug 
Heterozygous normal bug with one mutant r allele and one normal allele
