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.

Explain the difference between repetition and replication. plz
Answer:
Repetition: Doing something over and over/doing something repeatedly
Replication: Duplicating something/duplicating yourself
Explanation:
I hope this helps :)
Answer:
Repetition refers to performing multiple trials throughout an experiment.
Repetition reduces mistakes and increases one’s confidence in the results.
Replication refers to the ability of a process to be repeated by another individual.
When a scientist replicates another’s experiment, the experiment should produce the same results.

what is a filament? (plant topic)
Answer:
The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops. The word filament is from the Latin word filum, which means "thread." Filament, in fact, can be a synonym for thread.
Answer:
A filament is the slender threadlike object or fibre, especially one found in animal or plant structures.
a filament can also be defined as the slender part of a stamen that supports the anther.

Questions:
1. How is a cell membrane like the plastic bag in the experiment?
2. Define diffusion.
3. List two reasons why molecules will not diffuse into cells.
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.

Which element has fewer than four dots in its electron dot diagrams?
O arsenic (As)
sulfur (S)
krypton (KI)
O gallium (Ga)
Answer:
O gallium (Ga)
Explanation:
Your Welcome;)
The element that has less than four dots in its dot structure is gallium.
What is Lewis structure?The term Lewis structure has to do with the arrangement of outermost electrons in an atom. The Lewis structure consists of the symbol of the element as well as the number of electrons in the outermost shell shown as dots.
Gallium is a member of group 13 hence it has three electrons in its outermost shell. Therefore, gallium has less than four electrons in its dot structure.

Which of the following statements about eukaryotes is not true?A) They contain organelles like mitochondria, chloroplasts, the endoplasmic reticulum and the nucleus.B) They are usually 10 to 100 microns in diameter.C) They can be either unicellular or multicellular.D) They are also called archaea.E) All of the above are true of eukaryotes.
Answer: Option B, D and E.
They are usually 10 to 100 microns in diameter.
They are also called archaea.
All of the above are true of eukaryotes.
Explanation:
Eukaryotes are organisms that have nucleus and it is surrounded by nuclear envelope and membrane bound organelles in the cell cytoplasm.
They can either be unicellular or multicellular compared to prokaryotes that are Majorly unicellular.
They are not usually 10 to 100 microns because most eukaryotes are multicellular organisms and they are bigger in sizes visible to the eyes like fish, goat,humans.
Eukaryotes are not usually archaea because archaea is are Majorly prokaryotic organisms that are unicellular and have no nucleus.

Why do you think invasive species are more of a problem in human altered biomes (anthromes) than they are in a biome that has not been altered by human activities?
Answer:
invasive species are a problem both in anthropogenically altered and natural environments
Explanation:
An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.

The diagram is a model of the structure of glucose. The structural formula of glucose, C6H1206, shows a ring of 5 carbon atoms and 1 oxygen atom. 4 carbons in the ring are each bonded to an -H and an -OH group in addition to 2 neighboring atoms in the ring. The fifth carbon is bonded to a CH2OH group. What structural feature does glucose share with larger carbohydrates? A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom B. the presence of double covalent bonds between carbon atoms C. strong bonds between carbon atoms that cannot be broken D. ionic bonds between carbon atoms and oxygen atoms
Answer:
The correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom
Explanation:
Carbohydrates are the primary and major component of diet, these molecules give vitality to the body, predominantly by means of glucose, a fundamental sugar, which is an part of the starch and a fixing in different staple nourishment diet choices.
the significant chemical formula of carbohydrates is (CH2O)n. It can be exhibited or express by the proportion of the carbon to hydrogen to oxygen which is 1: 2: 1 in the particles of starches. Starches are additionally arranged into three sub-sorts, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the basic sugars, for instance, glucose.
Thus, the correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom

If a pea plant's alleles for height are tt, what is true of its parents?
A. Both parents were tall.
2 Pts
B. Both parents were short.
C. Both parents contributed a recessive allele.
А E
D. Both parents contributed a dominant allele.
Answer:
C
Explanation:
tt is a recessive allele so it can only be tt if the parents were both tt&tt or Tt&Tt
Answer:
C.
Reason:The plant got it's tt alleles from it's parents, so they would have had to have the recessive alleles to pass it down. This does not necessarily mean that the plants were short, though, as parent plants who both had Tt alleles would have had a chance to have an offspring with tt alleles also.
