Explanation:
Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.
What are the various types of energy?The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.
Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

How has the discovery of Gram Staining
revolutionized how microbes are treated
Answer:
See the answer below
Explanation:
The discovery of Gram staining has revolutionized how microbes, especially bacteria, are classified. Bacteria that are positive for Gram staining are classified as Gram-positive while those that are negative to the procedure are termed Gram-negative.
What constitutes positivity or negativity to the Gram staining procedure is the ability of the cell walls of bacteria to either retain a dye or allow it to be washed off during the procedure. The components of the cell wall differentiate Gram-positive bacteria from the Gram-negative ones and confer the ability to retain dye on the former. Gram-positive bacteria have thick peptidoglycan cell walls and lower lipid contents as compared to the Gram-negative bacteria and with this, they are able to retain the color of the stain used during the Gram staining procedure.
During the Gram staining, a scoop of the bacterial isolate is usually smeared and heat-fixed to a glass slide. Thereafter, crystal violet drops are added to the slide, poured off, and then rinsed with water. A few drops of iodine are then added and allowed to stay for a few seconds before being poured off and rinsed. A decolorizer (an alcohol) is then added to the slide, allowed to stay for a few seconds before it is washed off. The addition of a counterstain follows and the slide is allowed to stay for another few seconds before the stain is washed off. The slide is then rid of water and then viewed under the microscope. A Gram-positive bacterium will able to retain the color of the dye which is purple while a negative bacterium will lose the color of the dye and appear red under the microscope.
Which statement is not an example of intercellular communication? A message travels between gap junctions. An electrical signal causes muscle cells to contract together. A molecule stimulates a target cell via a receptor. A message is distributed across plasma membrane.
Answer: D
Explanation:
A message distributed across a plasma membrane is not an example of intercellular communication. Therefore, option D is correct.
What is intercellular communication?information that is transferred from one cell to another. Cells communicate with one another by making physical touch or by releasing a chemical that is subsequently absorbed by another cell. Cells must communicate with one another in order to develop and function appropriately.
Multicellular organisms use four different types of chemical signaling to communicate with one another: paracrine, autocrine, endocrine, and direct touch.
Examples of intercellular communication are when a message travels between gap junctions, an electrical signal, causes muscle cells to contract together, and a molecule stimulates the target cell via a receptor. Hence, option D is correct.

What is the purpose of the cellular process
The correct answer is H. transcribing information in the DNA sequence for the use by the cell
Explanation
The process shown in the image is DNA transcription, this is the first procedure in gene expression. In this process, the information contained in the DNA sequence is transferred to the protein sequence using various RNAs as intermediaries. During this, DNA sequences are copied to RNA by an enzyme called RNA polymerase that synthesizes messenger RNA (maintains DNA sequence information for the use by the cell), so DNA transcription could also be called messenger RNA synthesis. According to the above, the correct answer is H. Transcribing information in the DNA sequence for the use by the cell.

It warms air entering the body.
O It exchanges oxygen and carbon dioxide.
O It pumps blood to the organs.
O It creates sound through the voice box.
Answer:
it exchanges oxygen and carbon dioxide
Explanation:
You inhale oxygen and exhale carbon dioxide
Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.
The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.
It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.
The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.
The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.
Thus, the option 3 is not the function of the respiratory system.

What is cellular respiration ?
A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.
