If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is ______ compared to the cell.
A: hypertonic
B: none of the above
C: isotonic
D: hypotonic
Answer:
it would be A: hypertonic
If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is hypertonic compared to the cell.
TONICITY:
Tonicity is the ability of a solution to induce movement of water in and out of a cell. Tonicity can either be hypertonic, hypotonic or isotonic in nature. Hypotonic solution is a solution that is lesser in solute concentration compared to the cellular solution while hypertonic solution is a solution that is greater in solute concentration compared to the cellular solution. This means that the glass of water with 20% salt is hypertonic (higher in concentration) to the cell containing 5% salt.Learn more about hypertonic solution at: https://brainly.com/question/8984839?referrer=searchResults
What characteristic of viruses distinguishes them from cells? They lack an independent metabolism. Their traits do not evolve in response to selection pressures. They are not separated from their environments. They do not have hereditary material.
Answer:
The correct answer is "They lack an independent metabolism"
Explanation:
Viruses are usually active/alive in a living environment and become inactive in non-living environment; these is because they rely on the metabolic activities of the invaded living environment/cell. This property is a sharp contrast to normal living cells that are able to metabolize different substances independently using several organelles.
Answer:
The do not have hereditary material.
Their traits do not evolve in response to natural selection.
They lack the ability to live independent of a host.
They are not separated from their environments.

Why do you think the starch molecule shown is a good source of energy for an organism?
A. The many bonds in the starch molecule store energy.
B. The starch molecule is made of atoms.
C. Starch is the only type of molecule that provides energy.
D. A starch molecule is made of more than one kind of atom.
Please help! I suck at Science!
Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
Answer:
Oxygen cycles keeps the flow of oxygen at a constant rate.
Explanation:
The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.
Answer:
A.) The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

Do fungi have cilia, flagella or pseudopodia for locomotion?
i) Yes
ii) No
Answer:
Yes
Explanation:
Cilia and flagella are also known among plants and animals, although they are absent from the true fungi. In some protists, single cilia have, in effect, been replaced by compound ciliary organelles (e.g., membranelles and cirri), which may be used effectively in locomotion and feeding.
3. Which of the following is a defining characteristic of a prokaryotic cell?
a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement
Answer:
C
Explanation:
Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.
The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.
What is a prokaryotic cell?Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.
They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.
The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.
Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

Why don’t we have a complete fossil record of all life that’s ever lived?
Answer:
Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.
Explanation:
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.
Please mark me as the brainliest
Answer:
Sediment has to cover the bones in order for fossilization to take place
Explanation:
Fossil formation requires a mix of physical and biological conditions. Fossils have to be exposed in oder to find them too, so there might be some that are just too deep in the earth for us to find them
