coevolution :) hope this helps
Explanation:
Answer:
To create policies to <em>control or forbid</em> the use of DDT
To create educational programs for the people.
Explanation:
As the individual can not be controlled once it is released, the actions to take abut this problem must be focused on other perspectives. Two main actions would be usefull to improve the condors´ situation:
One of them is to create policies to control or forbid the use of DDT, to reduce contamination in different food and water sources. There are too many animals that get contaminated for feeding on vegetables or other animals grown on perturbed soil, and for drinking polluted water. When these animals die, condor feeds on them and also dies. It is important to avoid using these products that affect the whole biodiversity, including human beings.
The other action is to educate people. It is very important to create educational programs that are accessible to everybody and by which it is possible to teach people about the condors´ biology, feeding behavior, and reproductive rate, among others. People should know that these animals are not dangerous, that they only feed on dead animals, and that their reproduction rate is very low. If people do not have any knowledge about this species and its situation, they will not be able to protect it.
Answer:
The correct answer is - 2 genes.
Explanation:
The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:
suppose there are only two gene - TT dominant over tt and CC dominant over cc
then the cross would be - RRCC - rrcc
gametes - RC and rc
Cross F1: RrCc
Self cross in F2:
offspring by Punnet cross are:
RRCC -->1/16
RRCc, RrCC .---> 4/16
RrCc, RRcc, rrCC--->6/16
rrCc, Rrcc--->4/16
rrcc ----> 1/16
thus, the correct answer is 2 genes
