what is the role of amino acids in protein synthesis
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧Answer:✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
Amino acids, long considered simply substrates for protein synthesis, have been recently shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.
Explanation:
The correct tRNA with the anticodon (complementary 3 nucleotide sequence UAC) binds to the mRNA using the ribosome. This tRNA delivers the correct amino acid corresponding to the mRNA codon, in the case of the start codon, this is the amino acid methionine.
They have been shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.

Identify the correct statement about bond formation between atoms:Required to answer. Single choice.
(1 Point)
It increases the energy and decreases stability
It decreases the energy and increases stability
It increases the energy and increases stability
It involves no change in energyose
Answer:
It decreases the energy and increases stability
Explanation:
When atoms come together, they chemically bond together to form molecules and compounds. The atoms form bonds by either sharing their valence electrons (covalent) or via the ionic charges of each atom.
The formation of bonds between atoms strengthen the molecule formed. This bond formation DECREASES THE ENERGY due to energy loss during the process but INCREASES THE STABILITY of the molecule. This means that atoms in a bond are MORE STABLE than single/individual atoms. However, bonds with higher orders are more stable than that with lower orders.
Liquid is the state of matter of a substance...
A.. that has a definite shape and volume
B.. that has neither a d finite shape nor a definite volume
C.. that has a definite shape and weight
D.. that has a definite volume, bust not definite shape
I need a answe ASAP the subject is science btw
Answer:
D. that has a definite volume, but no definite shape
Explanation:
There are mainly three states of matter and these are: solid, liquid and gas.
Liquid has a definite volume because its particles still remain in contact although they're moving freely. On the other hand, such free movement of the particles render it to have "no definite shape." This is the reason why liquid takes the shape of the container it is poured into.
If you pour a 500-ml liquid into a rectangular-shaped container, it will look rectangular. However, its volume of 500-ml will remain the same.

Giraffes have changed over time to have long necks so that they can reach leaves on tall trees and drink water from a low pool even though their legs don’t bend. What big idea of biology does this situation illustrate?
Answer:
this illustrates that giraffes have adapted over time to their surroundings and needs.
Explanation:
i dont know if this is correct but it seemed like the obvious answer to me if i need to elaborate tell me
The big idea of biology this incident show is adaptation as the giraffes adopted the habit according to the situation which continues since long time.
What is adaptation?Adaptation is defined as a change in habit or body structure of an organism according to situation to get fit for survival in changing environment.
Adaptation is very important factor for survival of organisms and there are several types of adaptation such as behavioral, physiological, and structural adaptation.
Charles Darwin proposed the theory of adaptation which states that "an organism that is able to adapt to changing environment will survive, the rest will be eliminated.
Therefore,The big idea of biology this incident show is adaptation as the giraffes adopted the habit according to the situation which continues since long time.

After examining the fossil record, scientists have determined that scorpions today are much
smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion
species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the
following conclusions is supported by this information?
F Scorpions living today have increased their numbers since they first appeared.
G Scorpions in the fossil record are smaller than their descendants are.
H Scorpions have changed as a result of natural selection,
J Scorpions do not appear in their original state in the fossil record.
After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. Scorpions in the fossil record are smaller than their descendants. Thus option G is correct.
What is fossil ?A fossil is nothing but the impression living organism, commonly observed fossils are from bones, formed from shells, exoskeleton, hairs, skin imprints, and even petrified wood.
Animal footprints, tracks, trails and become fossilized, if a specimen is older than 10,000 years, it qualifies as a fossil. From evolutionary perspective fossils provide the important information and insight about an organism and its habitat.
The bodies of the organisms do fossilize under right environmental conditions, these fossils are called as soft-fossils and leave an imprint of their bodies on the rock.

Which of these is not considered a potentially hazardous food?
Answer:
Packaged foods ( e.g. muffins, cookies or candies ) are not considered as a potentially hazardous food .
Explanation:
A potentially hazardous food is that food ( natural or man made ) which supports the rapid and progressive growth of infectious and toxin - producing microorganism. These foods are typically foods having high protein content or carbohydrate content , have high moisture content or low acidity . Examples of potentially hazardous food includes meats, eggs , cooked beans or peas ,cut fruits and vegetables , cooked vegetables, cooked rice , raw seeds and sprouts , etc. So , packaged foods are not considered as hazardous as they are packaged and so are protected from microbes as they are not in contact of atmosphere . All the other foodstuff , even boiled food is also hazardous as they provide necessary conditions required by microbes to grow like moisture, etc.
