What do the phosphorylated tyrosines on activated rtks do?.
Triggers the intracellular signaling and serves as a binding sites for signaling protein.
Function perform by phosphorylation of tyrosinesThe phosphorylation of tyrosines triggers the assembly of an intracellular signaling. The newly phosphorylated tyrosines serve as binding sites for signaling proteins that then pass the message on one to other proteins.
In conclusion, phosphorylated tyrosines triggers the intracellular signaling and serves as a binding sites for signaling protein.

How do organisms form carbon films?
Answer:
when an organism is covered by sediment,it begins to decay, when decaying,the organism releases a gas.This process in turns leaves a thin film of carbon that preserves part of the organisms.The hallow that forms on the sediment is the carbon film that contain fossils of the organism.
How are the products and reactants of photosynthesis and cellular respiration related?
The formation of food by trapping the sunlight is called photosynthesis. The digestion of the food to get the energy in the presence of oxygen is called respiration.
These two processes are interrelated with each other because the product of photosynthesis is glucose which is made up of carbon dioxide and oxygen.
In respiration, the cell uses the molecule which is made in the process of photosynthesis that is glucose. It breakdown into its monomer and give the energy.
Hence, In this way, these reactions are inter- related.

In which part of the cell cycle do the mitotic spindles assemble, bind to chromosomes, and move the sister chromatids apart?
Answer:
During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers.

Explain why insect farming is more sustainable than raising large livestock, such as cattle or chickens. Do you think more Americans will embrace the idea of eating insects? Why or why not?
Answer:
The major environmental advantages of insect farming compared to livestock production are as follows: (1) less land and water is required; (2) greenhouse gas emissions are lower; (3) insects have high feed conversion efficiencies; (4) insects can transform low-value organic by-products into high-quality food or feed.
Insects release fewer greenhouse gases than traditional livestock. Rearing traditional livestock accounts for 18% of greenhouse gas emissions (pdf, p . 63), which trumps emissions by the transportation industry. ... Insects also release much less ammonia and methane than pigs and cattle.

can you consider having wavy hair as a case of incomplete dominance pattern?why you say so?
Answer:
Explanation:
Hair type is an interesting case of something called incomplete dominance. What this means is that with hair type, if you have one of each version of the gene, you get a mix of the two or wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. Back to your specific situation.

Do you think that our society should try to genetically “engineer” babies? Do you think that one day we will? Explain your answers.
Im giving out brainliest!
Answer:
I think they should not genetically engineer babies because it is inhumane, they might as well make robots and forget about humans. Sadly I think one day we will, if they are able to implant a baby in a woman, they will soon be able to make a baby without a womb.
Answer:
I don't think we should "engineer" babies, they have their own life and changing that to make another that God did not make will turn out weird. God creates the babies, only he can make them perfect. But sadly, yes, I think people will try to "engineer" babies.
Which coast of north America has the greater amount of earthquakes, volcanoes and mountain s?
Answer:
There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes
The west coast of north America has the greater amount of earthquakes, volcanoes and mountains.
What is Earthquake?This refers to violent shaking of the ground due to movement within the earth crust.
The west coast is the area which is closest to the divide between the North American plate and the Pacific plate and contains many tectonic plates which is why it has greater amount of earthquakes, volcanoes and mountains.
