It cannot be possible to break even in an energy transformation. Thus, option D is correct.
what is energy transformation?
The primary forms of energy are light, mechanical, chemical, nuclear, electrical, heat, and sound.
Energy only convert from one form to another is known as energy transformation or conversion.
The Sun is the primary source of energy that is nuclear energy changed into electromagnetic energy like light energy.
This light energy travels in the form of waves reach the earth surface taken up by plants for doing photosynthesis.
Now light energy is converted into chemical energy which can be used up by animal and human in their food.
The chemical energy of the food converted into heat and mechanical energy which maintain the body’s temperature and involve in various physiological process like motion, breathing, standing, or running.

Answer:
I think option A

Answer:
A
Explanation:
That is what it is made up of and what it has to have.
Sam has a mutation in a gene that affects the function of a transfer RNA (tRNA). Human cells have 20 different types of tRNAs, and each adds a different amino acid to growing peptide chains, which form proteins. Based on what you know so far, would you expect this mutation to affect all proteins produced in Sam's cells? Explain your reasoning.
Answer:
No
Explanation:
The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.

write a summary about the cell theory
Answer:
Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:
all organisms are made up of one or more cells,
all the life functions of an organism occur within cells,
all cells come from preexisting cells.
Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:
all known living things are made up of one or more cells,
all living cells arise from pre-existing cells by division,
the cell is the fundamental unit of structure and function in all living organisms,
the activity of an organism depends on the total activity of independent cells,
energy flow (metabolism and biochemistry) occurs within cells,
cells contain hereditary information (DNA) which is passed from cell to cell during cell division,
all cells are basically the same in chemical composition in organisms of similar species.
The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Later, Rudolf Virchow made significant contributions to this theory.
Why is it important to study cell theory?Cell theory is critical for understanding biology because cells are the foundation of all life. We can have unicellular organisms such as bacteria and yeasts. cell division, the division of a cell from one to two to four, is the foundation of all living things' growth and development.According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Rebuttal:
Answer:
Explanation:The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

Answer:

The oceans are primarily composed of carbon and hydrogen elements.
What are elements?An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.
The six elements found in all organisms are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur; collectively called biological elements and shown as the acronym CHNOPS. These elements can bond with each other as well as other elements to create molecules.
Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

Answer:
pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution
A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. When a solution is neutralized, it means that salts are formed from equal weights of acid and base. i hope this helps you
