Answer:

B) 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.

What do you think will happen if we continue to destroy the world's rainforests?​
AVprozaik [17]

Answer:

CO2 levels will dramatically increase as well as food level supply will decrease. Oxygen levels will decrease too.

Explanation:

 Plants take in CO2 and produce Oxygen. Without plants, they can't take in CO2, and it is a necessity for them to take it in. Plants would die. Food supply would decrease because plants produce glucose during photosynthesis. Glucose is a kind of natural sugar that will be lost. Plants produce fruits or vegetables, so if there are no plants then no food.

Hope this helps!

Oduvanchick [21]

Answer:

The correct answers are B and C. The tsunami waves were as high as 500 feet, and it was triggered by a 9.1 magnitude earthquake.

Explanation:

The 2004 Indian Ocean tsunami was a series of tsunamis that swept the shores of most countries along the Indian Ocean on December 26, 2004, killing almost 280,000 people. This is considered one of the biggest natural disasters in history. The tsunami was caused by a huge 9.1 magnitude earthquake that shook the underwater off the west coast of Sumatra. This was the third largest earthquake measured by a seismometer. The ensuing tsunamis reached a height of 30 meters in some places when they made landfall. It has been confirmed that 131,028 people have died in Indonesia. More than 30,000 died in Sri Lanka and thousands died in India and Thailand. In Somalia, 4,500 km from the epicenter, 176 people were killed and about 50,000 people lost their homes. $ 14 billion in emergency aid was collected for the worst-affected countries.

What is a reproductive strategy
Bumek [7]
A reproductive strategy presents an approach of a type of an organism to reproduction and of taking care of it's offspring.  

Generaly speaking, there are two main reproductive strategies, K and R reproductive strategies.

The organisms that apply the R strategy produce a great number of small, independent offspring and when the offspring is born or hatched it's left to
try to survive on its own. This strategy is used by bacteria, many invertebrates, and reptiles.

On the other hand, the K strategy organisms produce a small number of offspring that they care of for a significant amount of time after they are born. This strategy is used mostly by mammals and birds.
