The missing part of this question is as follow:
Redi placed pieces of meat in several jars. He divided the jars into two groups. He covered the first group of jars with fine cloth. He left the second group of jars uncovered. Redi observed the jars for several days. He saw files on the cloth of the covered jars, and he saw files laying eggs on the meat in the uncovered jars. Maggots appeared only on the meat in the group of jars left uncovered
Answer:
The correct answer is - b. Covering one jar and leaving the other uncovered.
Explanation:
Variable or the factors in an experiment that is subject to change or that affects the particular experiment. In the experiment of F. Redi, he used two groups of jars one covered with fine cloth and the other open and exposed to the environment.
There is a change in the result of the experiment of Redi due to these variables as the jar that was covered has no maggots while maggots appeared in open jar.
The ocean life would die off because less salinity in the water and if the currents decrease in strength the nutrients they carry would not make to the life in the oceans and ocean life would die.
b. solids, liquids, and gases
c. solids and liquids
d. solids and gases
Answer: b. solids, liquids, and gases
Explanation:
A soil is a mixture of solids, liquids and gases. The solids are in the form of coarse to fine sediments which are added up to the soil by the weathering of the parent rocks. The liquids are in the form of water which adds up in the soil through the tiny pores by sources like river, rainfall, oceans and others. The gases such as carbon dioxide, oxygen, nitrogen oxides diffuse into the soil through tiny pores these are essential for the growth of plants and soil microorganisms.
The digestion of proteins, including human flesh, involves enzymatic processes performed by proteases. These begin in the stomach with pepsin and continue in the small intestine with enzymes like trypsin.
The chemical reactions responsible for the digestion of proteins, including human flesh, are primarily enzymatic digestion processes performed by proteolytic enzymes, known as proteases. The process begins in the stomach where the enzyme pepsin starts the breakdown of proteins into smaller chains called polypeptides. This process continues in the small intestine where other proteases, like trypsin and chymotrypsin, further break down these peptide chains. Finally, the smallest units of proteins, amino acids, are absorbed into the bloodstream.

B. Pollution
C. Invasive species
D. Climate change
The correct answer is A. Healthy ecosystems. The remaining three are actually quite the opposite and they destroy the healthiness of ecosystems. A healthy ecosystem is not polluted and has balance between species which in turn ensures that there's no climate change because there's nothing to affect it.
A.) The inputs are different than the outputs.
B.) The atoms of hydrogen, oxygen, and carbon are rearranged.
C.) There are equal numbers of atoms on each side of the equation.
D.) The number of molecules is the same on either side of the equation.
There are equal numbers of atoms on each side of the equation. The correct answer is C.
The balanced chemical equation for cellular respiration, C6H12O6 + 6O2 → 6CO2 + 6H2O + heat + ATP, exemplifies the law of conservation of matter. This law asserts that matter cannot be created or destroyed, only transformed. In this equation, equal numbers of atoms are present on both sides, symbolizing this principle.
While the reactants, glucose (C6H12O6) and oxygen (O2), undergo rearrangement, their total mass remains constant. Carbon, hydrogen, and oxygen atoms are transformed into carbon dioxide (6CO2) and water (6H2O) while releasing energy in the form of heat and ATP.
This equation showcases the fundamental scientific concept of matter conservation in chemical reactions.
