Virtual Access to images of mars will help kids better understand science because they get to see what life is like on planets, other than the one they live on. It’s a great educational experience, they get to compare and contrast things from where they are to Mars. Hey
Hope this helps! :)
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
Answer:
Option-C
Explanation:
The mitochondria organelle is a membrane-enclosed organelle which perform the function of producing energy in the cells.
The inner membrane layer of the mitochondria is adapted in a way that increases the surface for the enzyme which produces an energy molecule called ATP. Therefore the enzymes that synthesize the ATP molecule are known as the ATP molecule.
The ATP in the cell is produced by a complex process known as cellular respiration. The citric cycle takes place in the matrix of the mitochondria.
Thus, Option-C is the correct answer.
Answer:during action potential the cell membrane becomes more permeable to sodium ions to depolarized the cell to pass the nerves
Explanation: During resting potential the cell membrane contain more potassium ions inside of the cell then outuside to keep the cell negatives internally and this job has been doing by sodium -potassium pump which push two k+ ions inside of the cell & pulled 3 Na+ ions outside of the cell and thus maintain resting membrane potential but when neurotransmitter attached to the channels and tells it to open.So, they activate the m sodium gate which usually closed at resting membrane potential and start the movement of more sodium ions to inside of the cell to depolarize the it.
