Answer:
The first option
Explanation:
Groundwater flows faster where the hydraulic gradient and/or hydraulic conductivity are larger. Groundwater flow velocities are much slower than surface water flow velocities, except in limestone karst formations, where groundwater flows through caves and large solution channels.
Answer:
Amount of air inhaled or exhaled per breathing stroke is called as tidal volume. Tidal volume is 400 ml for women while for men it is 500 ml.
Explanation:
In respiration, tidal volume is defined as the volume of air that a person inhales or exhales in one stroke of normal breathing.
The tidal volume varies in adult men and women. In resting condition, tidal volume is 400 ml for women while for men it is 500 ml.
This tidal volume varies with the requirement of the body. During intense physical exercise the amount of gas intake increases in order to full fill the requirement of body and hence the tidal volume increases.
Answer:
True
Explanation:
B cells are B lymphocytes and are one of the types of white blood cells. Their main role is in the acquired immune system in which they help in the humoral immune response of the body by the secretion of antibodies. The maturation of the B cells occurs in the bone marrow in mammals. But in birds, these cells mature in an organ named bursa of Fabricius which is a lymphoid organ in birds. These B cells were first isolated form the bursa of Fabricius of the birds.
After much physical exertion, Lactic builds up in the body, as well as carbon dioxide levels
It was developed by Alfred Wegener around 1912-1915 time frame. He proposed his theory of the "continental drift". He proposed that the continents plowed through crust of ocean basins. He said that the continents look like a puzzle piece to put together. It's very interesting.
Hope this helped :)
have a great day
