Answer: Paleozoic
Explanation:
Not as many rocks existed from the precambrian era
This would be primary succession. Primary succession is succession starting from bare rock. Succession may start with weathering of the rock to create small pockets of lose soil. Seeds of pioneer plants may be carried by the wind to fall into pockets of soil with sufficient moisture to allow germination. The growth of pioneer plants will further break up the bare rock, creating a deeper layer of soil. As the plants grow, dead leaves and roots enrich the soil with organic content. Small animals start to colonise the area, such as gophers, who further break up and enrich the soil. The plants change from pioneer plants to plants of a specific biome. Succession will continue in this fashion until until an equilibrium is achieved.
In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
This process is called meiosis. Mitosis produces two identical daugheter cells, each with 12 chrimosomes. Meiosis produces four daughter cells with 6 chromosomes.
Answer:
Corbin recently found out that he has cancer, and he now strictly follows a treatment, diet, and exercise program that the doctor thinks will be helpful in keeping the cancer from spreading. These behaviors best illustrate <u>problem-focused</u> coping.
Explanation:
Problem-focused coping seeks to tackle the stressor head-on allowing the individual greater perceived control over their problem resulting in :
- Managing and changing the stressor
- Use if problem seems alterable
- Confrontice coping
- Planful problem solving
As Cobbin is strictly following treatment, diet and exercise programs that the doctor thinks will be helpful in keeping the cancer from spreading, Cobbin is showing <u>problem-focused coping.</u>
