Answer:
thanks to the genetic code, this allows cells to decode an mRNA in an amino acid chain
Transfer RNAs, or tRNAs, connect the mRNA codons with the amino acids for which they encode. One end of each tRNA has a three nucleotide sequence called anticodon, which can be attached to a specific codon of the messenger RNA. The other end of tRNA carries the amino acid that specifies the codon that is present in the messenger RNA
Active Transport - requires chemical energy because the process of transport is the movement of biochemicals from areas of lower concentration to higher concentration.
<span>Passive Transport - does not require energy because the process of transport is the movement of biochemicals from areas of higher concentration to lower concentration. </span>
Types of transport:
Active Transport - endocytosis, cell membrane/sodium-potassium pump and exoctyosis
Passive Transport - diffusion, facilitated diffusion, and osmosis.
Types of particles transported:
Active Transport - proteins, ions, large cells, complex sugars
<span>Passive Transport - anything soluble in lipids, small monosaccharides, water, oxygen, carbon dioxide, sex hormone, etc.</span>
One of the major components of cellular membranes is a class of molecules known as glycerophospholipids, which are synthesized from glycerol-3-phosphate (G3P) in a de novo pathway that initially produces phosphatidic acid (PA) and diacylglycerol (DAG) or cytidine diphosphate-DAG (CDP-DAG) (1–3
FRICTION is the force of resistance that acts on an object when the object moves against other matter
Explanation:
There are many types of friction. An example is static friction between objects that are not moving relative to each other. Kinetic friction, on the other hand, is between moving objects. Viscosity is related to friction in flowing liquids.
When a solid matter is moving in a fluid (such as water or air), the friction is usually referred to as drag.
Friction is experienced in everyday life. An example of its importance is in the braking of moving vehicles. Without friction, cars would be unable to halt to a stop when brakes are applied. The friction allows the tires to rub against the brake pads and the road and the kinetic energy of the car is transformed and dissipated as heat energy enabling the car to come to a stop.
