Answer:
A
Explanation:
These are the properties of an acidic solution. The higher the H+ ions in the solution the higher the acidity. H+ is also a measure of pH because pH is the negative log of the H+ ions in a solution. The more the H+ ions, the lower the pH of the solution. The H+ ions also allow the solution to conduct electricity because they take up the electrons and transport across from the anode to the cathode. Acidic solutions are also corrosive because they are highly oxidizing – the H+ ions accept electrons to turn to H₂ gas.
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.
They have to adapt to the water, the animals in the ocean, the way they hear and see.
Hopes this helps:
Answer: In 1998 scientists discovered that fungi split from animals about 1.538 billion years ago, whereas plants split from animals about 1.547 billion years ago. This means fungi split from animals 9 million years after plants did, in which case fungi are actually more closely related to animals than to plants.
Have a great day.
