If you cut a tree trunk into pieces, the resulting pieces and dust add up to the same mass as the original trunk. This is a demonstration of
Answer:
The law of conservation of mass
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
If a diploid tomato cell has 24 chromosomes, how many chromosomes will the tomato's sex cells have?a.12c.24b.6d.48
Answer:
12!
Explanation:
Sex cells only carry half of what makes up the organism's DNA. This is so that when they find a mate, in this case- another tomato, their sex cells and their partner's sex cells will add up to the appropriate amount of chromosomes in the organism's DNA. In this case, 24.
How might this change affect the structure and function of the protein?
Answer:
Explanation:
Three-dimensional folding of a protein is due to interactions among the R groups of the amino acids. Cysteine has a sulfhydryl group, which may form a disulfide bridge with another part of the polypeptide chain. Valine has no sulfhydryl group and is nonpolar, which will affect how the polypeptide will fold.

The function of the respiratory system is to break down food.
RESPIRATORY SYSTEM:Respiratory system is one of the system of living organisms that consists of organs, which functions in exchange of gases in and out of cells. The major organ of the respiratory system is the lungs. However, respiration majorly deals the breakdown of food molecules in the cells. These breakdown of food molecules release energy in form of ATP, which is needed to perform cellular activities. Therefore, the function of the respiratory system is to break down food.Learn more about respiratory system: https://brainly.com/question/3305440?referrer=searchResults

Lipids are...
A. Protein molecules
B. Similar to water molecules
C. Polar molecules
D. Nonpolar molecules
Answer:
The answer you are looking for is D.
Explanation:
Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. (non- polar molecules)
Lipids are fat molecules and are hydrophobic (water repulsive) in nature. Thus, option D is correct.
What are Lipids?Lipids are important biomolecules and are widely distributed in biological systems. Lipids are organic macromolecules.
Lipids are insoluble in water (polar) and require non-polar solvents mainly hydrocarbons for dissolution like petroleum, ether etc. Thus, non-polar in nature.
Lipids include array of molecules like fats, wax, steroids, vitamins (fat-soluble; A,D, E and K), hormones, oils etc and have diversified functions.
Lipids form an integral part of the cell membrane. It also surrounds membranous structures. It protects the cellular membranes by creating an insulating layer.
Lipids are essential for storing and conserving energy in mammalian body. It helps in metabolism of glucose by converting extra glucose to glycogen in adipose tissues.
Lipids also act as transport molecules in the body. Many lipids function as chemical messengers.
Therefore, Lipids play a pivotal role in living system.

Explain how to focus a microscope using the high power lens. Include any safety issues you need to be aware Answer
Answer:
Include any safety issues you need to be aware of. Answer: To focus a microscope using the high-power lens you have to use the focus adjustment knob but be careful because if you crank down too hard, you can damage the microscope and the slide.
Explanation:
Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).You must be very careful when using the high power lenses so you do not jam them into the slide. Ocular Lens - The ocular lens, or eyepiece, magnifies the image.

Sexual reproduction leads to variation which provides protection as different organisms will be more prone to different things
If the DNA code reads CCAATTGG then the tRNA code would read?
Answer:
CCAAUUGG
Explanation:
A tRNA is all the letters stay the same unless there is a T or a U. a T turns into a U and vise versa.
In case DNA code offers the reading CCAATTGG, the reading of the code tRNA would be:
CCAAUUGG
The term "tRNA or Transfer RNA" is described as the small atoms that may function for the purpose of carrying/transferring amino acids.In the given situation, "tRNA" code for the provided DNA code reading would be similar to the DNA except for T. The letter "T" would be replaced with U in tRNA and U become T while converting it to DNA.
Thus, "CCAAUUGG" is the correct answer.
