<u>Answer:</u>
Approximately, the oldest stromatolites are 3.6 billion years old on earth.
<u>Explanation:</u>
- Stromatolites is not only oldest earths fossil but conspiracy in that they are singular visual portal in deep time on earth.
- It is defined as laminated accumulation structure that is they stick up above sea floor .
- Stromatolite buildings includes oldest fossils which are 3.5 billions old when the earth were too unfriendly to support life.
- The study of fossil age, evolutionary, method of formation are known as paleontology.
- These specimens are considered as old fossils which are around 3.4 to 4.1 billions years old.
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>
Answer:
dimerization and phosphorylation
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism .
It would be A, they both have different properties, as they say it, different functions.
Because it transports energy for all cellular metabolic activities.
Hope this helps! :)
(if you could rate/thank me that would be amazing!)
