Answer:
a. True
Explanation:
Proteins are biopolymers composed of amino acids that appear in chains. These amino acids are formed by peptide bonds. Due to the functions they carry out, proteins are essential for the existence of life. Proteins can be found in both animals and vegetables. In animals, there are proteins that help protect the body, others are in charge of regulating metabolism. On the other hand, in plants proteins participate in cell division processes, membrane transport, catalysis of biochemical reactions, photosynthesis and respiration processes, synthesis of sugars, starches, and other compounds.
True. Protein can be found in both animals and vegetables. Therefore, option (A) is correct.
All living species need amino acid-based proteins to shape, function, and regulate their cells and tissues. Meat, poultry, fish, eggs, and dairy are protein-rich. These sources often supply all needed amino acids.
Proteins in vegetables and plant-based diets differ from animal-based proteins. Plant-based protein sources include legumes, soy, nuts, seeds, and grains like quinoa and amaranth. A balanced amino acid profile can be achieved by eating a variety of plant-based proteins. Therefore, option (A) is correct.

nitrogen fixation
assimilation
carbon cycle
Bacteria from the soil absorb nitrogen from the air and convert it into ammonium. This is an example of nitrogen fixation .
Answer:
The correct answer is - option D. rubbing hands in warm water.
Explanation:
The control group or the control is the variable or that is used in an experiment to check if the results are actually due to the experiment or to compare the result or effect of the experiment.
In this experiment, the independent variables are soap and the sanitizer and the dependent variable is the count of bacterial culture. To check the result or to compare the result that results are due to the experiment the control group is rubbing the hand vigorously in warm water.
B. produce mucus that protects parts of the digestive organs from the effects of powerful enzymes needed for food digestion
C. secrete buffers in order to keep the pH of the digestive tract close to neutral
D. provide protection against invading bacteria and other disease-causing organisms that enter the digestive tract in food
b. It is an electric discharge between two similarly charged surfaces.
c. It is caused by the rapid expansion of air along an electrical strike.
d. It always begins in a cloud and strikes the Earth.

The mouth and teeth break up the food and mix it with saliva.
Answer:
stomach
Explanation:
The stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric (say: GAS-trik) juices that also come from the stomach's walls.
