Answer:
CELLS! Living things use energy, move, consume water and food, etc. Any individual form of life that is capable of growing and reproducing is considered an organism. All organisms get water and other materials from the environment.
Explanation:
Which statement provides a conclusion about the transport of water in and out of cells based on the results of the student's experiment? A. Water moves freely both inside and outside the cell independent of the solute concentration. B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell. C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell. D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
Answer:
B.
Explanation:
The transport of water in and out of cells based on the percent concentration of solutes both inside and outside the cell.
The movement of water in and out of the cell is called osmosis. In the process of osmosis, water or solvent moves from low to high concentration of solute (towards high solute concentration). For example, if a cell is placed in a salt (solute) solution, the water will move out of the cell or towards high salt concentration and the cell will get shrink.
Hence, the correct answer is "B."

How does altitude affect climate patterns in a region? Areas at high elevations have cooler temperatures. Air continues to warm as it rises to a higher elevation. Tropical regions do not have many differences in altitude. High-altitude areas have less variation in seasonal temperatures.
Answer:
A. Areas at high elevations have cooler temperatures.
Explanation:
Areas with high altitude or elevations have cooler temperatures because air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."
Answer:
a

Which statement is FALSE about spontaneous generation theory? Group of answer choices When microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms. Spontaneous generation is a theory that life forms can be generated from non-living objects Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies. Louis Pasteur's swan-neck flask experiment demonstrated that spontaneous generation does not occur.
Answer:
Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies.
Explanation:
As rightly stated in the options of this question, the theory of Spontaneous generation is a theory that life forms can be generated from non-living or inanimate objects. Several scientists including Needham, Redi, Pasteur contributed to this theory experimentally by either proving or disproving it. Their contribution are as follows:
- John Needham boiled a broth containing living matter but noticed cloudy appearance representing microbial growth. Hence, when microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms.
- Francesco Redi, on the contrary, disproved the theory by conducting an experiment using meat. Redi DISPROVED the theory by concluding that flies were responsible for appearance of maggots on the meat. Hence, the statement that "Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies" is FALSE.
- Loius Pasteur also disproved the theory of spontaneous generation by using swan-necked flasks. His swan-neck flask experiment demonstrated that spontaneous generation does not occur

Which of the following best represents a function of a lipid within an organism? O Lipids are components of cell membranes All the answer choices are correct O Lipids are parts of proteins O Lipids form a large part of the helical DNA structure
Answer:
The statement that best represents a function of lipids within an organism is that they are components of cell membranes.
Explanation:
Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.
In living beings, one of the most important functions of lipids is to be the main component of cell membranes.
Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, membrane lipids fulfill a structural and protective function of the cell and its contents.
Regarding the other options:
Proteins are made up of amino acids, not lipids. Lipids are not constituents of the DNA structure.39

9. A family is looking to see how much of their electricity bill is coming from their clothes washer and drier. The washer uses 1500 watts and the clothes drier uses
2000 watts and the family pays $.10 per kilowatt-hour. The appliances runs approximately 30 minutes each day(total together). How much does the family spend
per week to run both these appliances? Show set up with units
Answer:
Per week expenses = $73.5
Explanation:
Given:
Washer uses = 1500 watts
Drier uses = 2000 watts
Kilowatt-hour = $0.10
Find:
Per week expenses
Computation:
Total uses = 1500 + 2000
Total uses = 3500
Week uses = 3500(30)(7)
Week uses = 735000
Per week expenses = (735000)(0.10)/(1000)
Per week expenses = $73.5

What is the most important reason to control the conditions of an experiment?
O to make the experiment easier to repeat
O to reduce the amount of data that must be recorded
O because this is necessary for graphing the data
O because this is necessary for the data to be valid
Answer:
The answer would be the last choice, "because this is necessary for the data to be valid."
Explanation:
This is because in an experiment, things must be controlled or monitored in most ways; otherwise, the result of the experiment will be different from what it was meant to be. An experiment should be as exact as possible. If this is not possible, results may be unreliable.

18. The structural diagram demonstrates two joined amino acids.
Which arrow points to the peptide bond?
A.3
B.1
C.4
D.2
Answer:D
Explanation:
The structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.
What is a peptide bond?The resulting bond that is formed between the two amino acids is called a peptide bond, and the resulting molecule is called a dipeptide. As more amino acids are added to the chain, a polypeptide is formed. The peptide bond is a strong covalent bond that holds the amino acids together in the polypeptide chain. It is important for determining the structure and function of proteins.
Hence, the structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.
