Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).
Explanation:
A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.
According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.
What is the independent variable in this experiment?
Answer:
The amount of light they receive.
Explanation:
In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.
The independent variable in this experiment is the amount of light received by each plant.
What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.learn more about independent variable here:

What type of cell is shown in the model?
A. Bacterial cell
B. Eukaryotic cell
C. Plant cell
D. Prokaryotic cell
Answer:
it is a Eukaryotic cell (B)
Explanation:
by process of elimination we can limit it down to B and D, a prokaryotic cell would look nothing like this so therefore it is B
The cell shown in the figure is a model of an eukaryotic cell. An eukaryotic cell consists of all the cell organelles and a well-defined nucleus. Thus, the correct option is B.
What is Eukaryotic cell?
An eukaryotic cell is also known as a true cell. These cells contain all the membranous cell organelles such as mitochondria, chloroplast, etc. and a true well-defined nucleus which are absent in the prokaryotic cell. An outer cell wall or cell membrane is present which encloses the protoplast (living matter) of the cell.
All the animals and plants are made up of eukaryotic cells. These cells contain all the organelles and hence are capable of independent existence. The genetic material is present in the form of DNA (deoxyribonucleic acid) in the nucleus of cells.
Therefore, the correct option is B.

how do mutations and natural selection lead to resistant populations of bacteria
Answer:
Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.

High tide is occurring on the sides of the Earth that are_______.
A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.
High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.
What is high tide?When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.
The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.
On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.
The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.
Thus, the correct option is D.

What were the ancestors of mitochondria according to the endosymbiotic theory?
20 points
A. Aerobic eukaryotes
B. Aerobic bacteria
C. Anaerobic bacteria
D. Chloroplasts
Answer:
d is your answer
Explanation:
Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.
What is endosymbiotic theory ?According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.
Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.
Therefore, aerobic bacteria are the ancestors of mitochondria.

Succession Interactive!
What is the difference between primary succession and
secondary succession?
Primary succession occurs in an area that is disrupted by a
fire or other natural disaster but secondary succession does
not.
Primary succession occurs after secondary succession.
Primary succession involves only plants but secondary
succession involves animals too.
Primary succession occurs in an area with no life and no soil
but secondary succession happens in an area where an
existing community was disrupted.
Answer:
Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.
Explanation:
Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.
- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.
- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.

An mRNA cap will be found on ____________.
a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.
