Dams provide water for 40% of irrigated land, yet there are disadvantages to dams. Which of the following is NOT a disadvantage of dam use?
a) loss of water due to evaporation
b) provide electricity for many countries
c) increase in salinity due to evaporation and runoff
d) increase in sediment buildup leads to less available water
e) depletion of river water
b) provide electricity for many countries
The statement which is not disadvantage for dams b) provide electricity for many countries
Dam is a building that is used as a barrier to the flow of river water so as to form a reservoir with water reserves. Dams are used to raise the water level in rivers to the height required for water to flow into irrigation canals and rice fields.
The flow of water in the dam can also be used as an alternative source of hydroelectric power that is capable of producing large amounts of electricity. By using a water wheel, the rotation of the water wheel in the dam will produce strong energy of motion. The motion energy from the water wheel can be utilized to generate electrical energy.
Apart from providing many benefits, the dams they build can have negative impacts such as damaging the ecosystem. salinity will rise due to evaporation that occurs in the water in the dam, as well as the amount of water will decrease due to the extinction of sediment causing reduced air availability. The volume of river water will also decrease because the water is trapped in the dam. The process of evaporation of water in the dam due the sun's heat energy can heat up the water in the dam and cause the water molecules to move faster and turn into a gas called water vapor. water vapor and rises into the atmosphere. Evaporation of dam water causes the amount of water in the dam to decrease, thus causing the water salinity to increase.

all the facts are true about leading strand that it is made continuously, - daughter strand elongates toward replication fork, only one primer needed and synthesized 5' to 3'
The straightforward new strand is the one that goes from 5' to 3' toward the replication fork. Because the DNA polymerase and the replication fork are travelling in the same direction, this strand is produced continually. The leading strand is the one that is constantly being created.

when you added primary antibody to the wells, what happened if your sample did not contain the antigen
when you added primary antibody to the wells, If the antigen was not detected, the main antibody was washed off.
Antibodies and proteins shield you from harmful chemicals when they come into touch with your body. Antibodies are created by your immune system to bind to these foreign chemicals and remove them from your body. Immunoglobulin is another term for an antibody. A foreign substance that enters your body is referred to as an antigen. This includes venom, allergens, bacteria, viruses, fungus, and other poisons. Your immune system makes an antibody protein that it employs to find and eliminate particular antigen. Surface molecules on antigens are different from ones your body typically produces. Your immune system thus recognizes an antigen as soon as it enters your body. Your immune system requests antibody defense in order to fight against this antigen invasion. The B cell produces antibodies (specialized white blood cells). A B cell expands and clones when it comes into touch with an antigen. These plasma cells, also known as cloned B cells, continuously produce antibodies into your lymphatic and blood systems.

Anatomically, the precentral gyrus houses the primary motor cortex, which controls free will movement. The temporal lobe, which is found behind the ears, is the second-largest lobe. The internal occipital lobe is separated from the parietal and internal temporal lobes by the parieto-occipital sulcus, a very deep sulcus that runs through the posterior region of the hemisphere.
The insula plays a crucial role in the processing of gustatory and sensorimotor information, risk-reward behavior, autonomic nervous system function, pain pathways, and auditory and vestibular functions.
