Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.
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:
symbiotic
Explanation:
symbiotic relationships benefit both organisms
I would go for 'c'. The reason being, is that it doesn't do much, and I am also assuming that offshore drilling will not affect underwater sources, which are linked to the ocean.
Answer:
Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms.
