Answer:
is used by commercial airplanes
Explanation:
The stratosphere is used by most commercial airplanes. This is because this layer of earth is stratified and more stable.
- The lowest level of the atmosphere is the troposphere.
- This layer is where all the bulk of the atmospheric gases are domiciled.
- Weather conditions occur here.
- This layer is not safe for flight due to its turbulent nature.
- The ionosphere is responsible for the transmission of radio signals around the earth.
- The earth's weather occurs in the region of the troposphere.
The statement given is the function of RNA.There are three types RNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis. Rribosomal RNA (rRNA) molecules form the ribosomes, ribosomes are the site of protein synthesis. Transfer RNA (tRNA) molecules carry amino acids and add to the chain of amino acids to form polypeptide chain or protein molecule.
Answer:
Forward chaining as the name suggests, start from the known facts and move forward by applying inference rules to extract more data, and it continues until it reaches the goal, whereas backward chaining starts from the goal, move backward by using inference rules to determine the facts that satisfy the goal.
Sensory information
The somatosensory cortex is a structure located in the middle of the brain on both the right and left hemispheres. The somatosensory cortex is responsible for processing information we receive from all our senses, including:
1. Visual information- what we see
2. Auditory information- what we hear
3. Kinaesthetic information- what we can touch or feel
4. Olfactory information- what we can smell
5. Information from our taste buds
The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.
