Which is a basic characteristic of all living cells?
cell wall
protein coat
energy metabolism
antibiotic resistance
Answer:
Energy Metabolism
Explanation:
In order to a living cell you need to be able to reproduce, have energy metabolism, etc.
This is a basic characteristic of all living cells called as the energy metabolism.
What is the Energy metabolism ?
Energy metabolism refers to all of the reactions worried in producing adenosine triphosphate (ATP) from nutrients, such as each cardio respiration (oxygen present), anaerobic respiration (fermentation) in addition to fatty acid and amino acid metabolism.
The residing cells of each organism continuously use strength to live to tell the tale and grow. Cells ruin down complicated carbohydrates into easy sugars that the cell can use for strength. Muscle cells can also additionally patron strength to construct lengthy muscle proteins from small amino acid molecules.

does not lead to a testable hypothesis
has a simple yes or no answer
Answer:
addresses a gap in knowledge
Explanation:
Every scientific experiment begins with an observation or a question. This question is called a scientific question. A scientific question is a question that helps the scientist or experimenter get to the root of an investigation, like a head start. One important character a scientific question is that it must be able to be tested via experimentation.
In this question, the phrase that best describes a good scientific question is that it should ADDRESS A GAP IN KNOWLEDGE. This means that it should aim at filling a void or contribute to knowledge.

When a true-breeding blue salamander is mated to a true-breeding red salamander, 100%of the offspring are blue. Assuming that salamander skin color is determined by a singlegene, which of the following statements are correct?A. The blue allele is dominant to the red alleleB. The red allele is recessive to the blue alleleC. The blue gene is dominant to the red geneD. The red gene is recessive to the blue geneE. Both A and BF. Both C and D
Answer:
Both A and B
Explanation:
True breed is a breed that is 100% identical with the parent, the traits inherited from that parents are 100% controlled by same allele of a gene hence they are exact copy.
A single gene can have several alleles, it is the allele that combines together that determines what is seen or expressed.
Allele for blue colour is dominant over allele for red color and that is what led to the phenotypic appearance of the offspring which is blue and the red color is masked. Also, because they are true breeds it means the genotype have the same allele e.g. AA

One difference between plant and animal cells is that (1) plant cells have cell walls; animal cells don't (2) plant cells can't move; animal cells can (3) plant cells live in water; animal cells don't ( 4) plant cells have a nucleus; animal cells don't (5) plant cells have vacuoles; animal cells don't
Answer:
1) Plants cells have cell walls; animal cells don’t.
Explanation:
Cell walls function is to help cells stick to each other, which is good for plants since they don’t move around. But as for animal, they need to move around so it’s not good for them to have it.
Without cell walls, animal cells can take on different shapes!
It makes it able to move easier, flexible.

What is the independent variable in this hypothesis, " Palo verde trees experience more growth during years with higher rainfall"?
Answer:
AMOUNT OF RAINFALL
Explanation:
The independent variable in an experiment is the variable that the scientist/experimenter manipulates or changes in order to bring about a response in the dependent variable.
In this case, the independent variable is the AMOUNT OF RAINFALL that the Palo verde trees were exposed to. This is because the amount of rainfall received is what is changed in this experiment while the growth of the Palo verde trees is the dependent variable, which is dependent on the amount of rainfall received (independent).

When the concentration of a substance higher on one side of the cells selectively permeable membrane, certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy. This process is called
A.passive transport
B.active transport
C. Mitosis
D. Replication
Answer:
A.
Explanation:
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
When certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
When diffusion takes place between compartments separated by a membrane permeable to that solute, it is called simple diffusion.
Passive transport does not require any additional energy other than the movement of the molecules, moving these in favor of their concentration gradient.
In other words, simple diffusion does not require ATP expenditure, since it is a spontaneous phenomenon.
The molecules that are mobilized by simple diffusion through the membrane are the nonpolar and small, the fat-soluble and the small polar ones, but without a net electric charge, such as H2O.
In the particular case of H2O, passive transport is called osmosis, the passage of water through the membrane by osmosis always takes place spontaneously and very quickly.
H2O will diffuse from the compartment with the lowest concentration of solutes or hypotonic medium, to the compartment with the highest concentration of solutes or hypertonic medium, in such a way as to equalize the concentrations in both compartments.
Therefore, we can conclude that when certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.

there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years (in fact, over 99% of all species that ever existed are now extinct!). given these facts, why do we care if human activity is driving other species extinct as we grow?
Answer:
This is because humans are causing species to go extinct at a faster rate than the normal rate.
Explanation:
It is documented that there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years. Some may say even if nothing is done there would still be extinction of this species which is true.
We care if human activity is driving other species extinct as we grow because humans are causing species to go extinct at a faster rate than the normal rate.

What is quantitative data ?The data expressing a certain quantity and amount or range is called as quantitative data. The two main types of quantitative data are discrete data and continuous data.
The difference between the qualitative data and quantitative data is the quantitative data is numbers-based, countable, or measurable while qualitative data is interpretation-based, descriptive, and relating to language.

Which of the following about the plasma membrane is not true?
a. It is made of lipid molecules b. It protects the cell's cytoplasm
c. It contains proteins d. It contains most of a cell's DNA
d. it contains most of the cells DNA
The folowing about the plasma membrane is not true is that It contains most of a cell's DNA. Correct Option is 4.
The plasma membrane, also known as the cell membrane, does not contain most of a cell's DNA. The DNA of a cell is primarily found within the nucleus in eukaryotic cells, or in the nucleoid region in prokaryotic cells. The plasma membrane, on the other hand, forms the outer boundary of the cell and separates the internal contents (cytoplasm) from the external environment.
It plays a role in protecting the cell, regulating the movement of substances in and out of the cell, and facilitating communication with neighboring cells. The plasma membrane is primarily composed of lipid molecules (option a) arranged in a phospholipid bilayer, along with various proteins (option c) that have diverse functions in cell signaling, transport, and structural support.
