The quadriceps muscles will contract.
Explanation:
Quardriceps are muscles of the thigh located in the front.
It is a group of four vastus muscles named as-the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris.
Muscles posses the ability of contraction so an action potential that will excite the muscle cells will obviously result in contraction of the muscles.
So we can conclude that on depolarizing the muscle cell of the quadriceps will result in contraction of quadriceps.
The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.

2)Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work. Focus on adding healthy food to your diet, rather than just taking unhealthy foods away. Try to eat a family meal every day at the kitchen or dining table.
3)Biomacromolecules are large biological polymers, such as nucleic acids, proteins and carbohydrates, that are made up of monomers linked together. For example, proteins are composed of monomers called amino acids.
4)The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed
5)Cellular metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. Cellular metabolism involves complex sequences of controlled biochemical reactions, better known as metabolic pathways.
6)Sugars, such as galactose, fructose, and glycogen, are catabolized into new products in order to enter the glycolytic pathway.
Answer:
Plants and trees are the primary sources of food for a food chain or a food web. If the population of the primary producers reduces than it affects the whole food web. If the deciduous trees are destroyed due to a fire, there will be less food available for the primary predators. As a result, competition will begin between them and their population will decline. Due to this, the population of other organisms which fed on the primary consumers will also decline.
