Answer:
Being cylindrical, phospholipid molecules spontaneously form bilayers in aqueous environments. In this energetically most-favorable arrangement, the hydrophilic heads face the water at each surface of the bilayer, and the hydrophobic tails are shielded from the water in the interior.

Where must an mRNA attach before protein production can begin?
Answer:
to a Ribosome
Explanation:
mRNA is produced inside the nucleus of a cell according to the genetic information present in the DNA of the cell. this process is known as Transcription.
Then it's sent to ribosomal subunits in the cytosol through nucleopores. then it attaches to the ribosome. the ribosome reads the nitrogenous base sequence and pairs the tRNAs with complementary nitrogenous bases. (your answer is here, but if you want to know more, continue reading it.)
Each tRNA contains a tri-nucleotide that is collectively known as an anticodon which has the complementary bases of the relevant codon on the mRNA.
Each tRNA has captured a protein. the type of protein is determined by the sequence of the anticodon.
It means two tRNAs with two different anticodons cannot bring the same protein to the ribosome.
the Ribosome separates the proteins attached to tRNAs and links them as a chain.
the final result is a polypeptide chain. I explained to you the basic protein synthetic process.

explain the roles of mRNA and tRNA in protein synthesis
Answer:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax
The thorax is a very vital and important organ in the human body.
It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.cIt is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.
When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases. When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases. Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law. Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.

Explain the importance of decomposers to a food web and their interaction with quaternary consumers.
Answer:
Decomposers recycle the nutrients in dead organisms allowing it to completely travel through the food web cycle, from producer, to consumer and back again
Explanation:
This recycling also applies to quaternary consumers, the predators that generally have no natural enemies, allowing the nutrients in their bodies to be recycled.

Answer:
Most of the iron that is removed from degraded hemoglobin is: recycled to the red bone marrow.
Most of the iron removed from degraded hemoglobin is recycled in the red bone marrow.
What is Hemoglobin?Hemoglobin is defined as an iron-containing oxygen-transporting metalloprotein present in the red blood cells of nearly all vertebrates as well as the tissues of some invertebrates that carries oxygen from the respiratory organs in the blood to the rest of the body.
The blood protein hemoglobin that helps carry oxygen throughout the body and carbon dioxide to your lungs. High hemoglobin levels can cause dizziness, fatigue, easy bruising, and other symptoms.
The iron which is present in hemoglobin which is removed is recycled from the red bone marrow.
Thus, most of the iron removed from degraded hemoglobin is recycled in the red bone marrow.

Give advantages of endothermic animals
Answer:
The advantages of endothermy are well known: the ability to occupy thermal niches that exclude many ectothermic vertebrates, a high degree of thermal independence from environmental temperature, high muscular power output and sustained levels of activity, to name but a few.
The major advantage of endothermy over ectothermy is decreased vulnerability to fluctuations in external temperature. Regardless of location (and hence external temperature), endothermy maintains a constant core temperature for optimum enzyme activity.

the two proteins directly involved in muscle contraction are broadly called
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.

What are coral reefs?A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Coral reefs are massive structures made of limestone deposited by coral polyps. Often referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species.
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.
