Answer:
B = hydrogen bonding
Explanation:
The water molecule consist of two hydrogen atom one oxygen atom. There is large electronegativity difference between oxygen and hydrogen. Both atoms are bonded through covalent bonds.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial negative. The partial positive end of one water molecule attracted towards the partial negative end of other moleucle. The attraction between them is called hydrogen bonding. In this way large mole are connected with each other. Hydrogen bonding is actually a weak bonding.
Answer:
It is important because plants would not be able to produce food for themselves, so the plant would die. Animals that feed on plants would not be able to survive, and animals that feed on other animals would die too because they would not have any food.
From experiments that scientists did with bacteria and viruses
Answer:
A. Blood pH will decrease slightly.
Explanation:
Answer:" AI'll practice these now and try to start them as soon as I can after my surgery."
Explanation:
→Leg exercise should commence immediately after surgery to avoid blood clot..
→Blood circulation to the legs can be aided by pumping the ankle or drawing a circle with the ankle
→Range of motion practise should be intensified;the injured parts should be flex slowly, and toes should be used to draw alphabets, with each leg lifted individually, not in prone position.
→Hip abduction should be carried out, so that the body is away moved from the center of the body
