Answer:
Carbon monoxide can kill. The gas forms when there is not enough oxygen to produce carbon dioxide -- essentially when the carbon in fuel is not burned completely. Carbon monoxide prevents oxygen in the blood from being carried throughout the body, causing asphyxiation.

The orange beetles are at an advantage because the predator is choosing the green beetles over the orange. The green beetle population may decrease, leaving mainly the orange beetles to reproduce and cause a greater orange colored beetle population over time.
Answer:
Explanation:
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
So, en the exposed example:
- J and K are autosomal genes
- J and K are separated by 60 M.U.
- 60 M.U. means that there is 60% of recombination.
Cross) J K / j k x j k / j k
Gametes) JK Parental jk, jk, jk, jk
jk Parental
Jk Recombinant
jK Recombinant
One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.
1 M.U. -------------- 1% recombination
60 M.U. ------------ 60% recombination
30% Jk + 30% jK
100 M.U. - 60 M.U. = 40 M.U.
40M.U.--------------40 % Parental (Not recombinant)
20% JK + 20% jk
Punnet Square) JK jk Jk jK
jk JK/jk jk/jk Jk/jk jK/jk
J K / j k = 20%
j k / j k = 20%
J k / j k = 30%
j K / j k = 30%
the mutation occurred in the gametes

Answer:
Answer is D. Because the dog and cat are behaviorally isolated from each other.
Explanation:,
Isolation can be explained as a situation whereby organisms that ca interbreed and produce offspring could not, due to some factors.
Behavioral isolation is an example of isolation, and can be explained as a situation whereby two organisms that can interbreed could not, because of the difference in their mating rituals or signal.
In this case, the mating rituals or signal of the dog is different from that of the cat, and thus, prevent interbreeding between them.
Note that, other forms or types of isolation are ecological isolation, temporal isolation and mechanical isolation.
Another name for behavioral isolation is ethological isolation.
