Explain why DNA requires structural robust and efficient storage and organization mechanisms/structures.
Answer:
DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.
Explanation:
DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.

___ NaF + ___Br2 ___NaBr + ___ F2
right answers only
Answer:
1. A (2,1,2,1)
2. C (single displacement reaction)
Explanation:
1) In this question, the given reaction is as follows:
_ NaF + _Br2 ➡ _NaBr + _ F2
In order to balance this chemical reaction between sodium fluoride (NaF) and bromine gas (Br2) to give Sodium bromide (NaBr) and fluorine gas (F2), we need to make use of COEFFICIENTS.
The same number of atoms of each element must be present on the reactants side and the products side.
- There are two atoms of fluorine on the product side, hence, we place coefficient 2 behind NaF
- There are two atoms of bromine on the reactant side, hence, we place coefficient 2 behind NaBr
After this, we get the order of coefficients as 2,1,2,1
2) A single displacement reaction is a type of reaction in which only ONE element is substituted by another element in a compound. In this reaction, 2NaF + Br2 ➡ 2NaBr + F2, fluorine is displaced by bromine in the compound NaF or in other words, bromine substitutes fluorine in the compound, hence, it is a SINGLE DISPLACEMENT REACTION.

Answer:
D
Explanation:
I just took this quiz so you are welcome
Codons are similar, both prokaryotic or eukaryotic cells have the same type of codons.
Codons are similar, both prokaryotic or eukaryotic cells have the same type of codons. Codons of both cells start with the same point or material but end with different point or materials. These codons are also different in these cells such as Prokaryotic codons usually specify different amino acids than those of eukaryotes.
The translation of codons is mediated by tRNAs in eukaryotes, but translation requires no intermediate molecules such as tRNAs in prokaryotic cells. Prokaryotic codons have contain different bases than that is present in eukaryotic cells so we can conclude that codons of both cells are similar in characteristics.

in which case would facilitated diffusion be needed?
A. With large polar molecules moving against the concentration
gradient
B. With very small non polar particles moving down the
concentration gradient.
C. With very small polar particles moving against the
concentration gradient.
D. With large non polar molecules moving down the concentration
gradient.
Answer:
The case in which facilitated diffusion would be needed is in the transport of large non-polar molecules moving down the concentration gradient.
Explanation:
Facilitated diffusion (FD) involves a form of passive transport, that is, it does not require energy and mobilizes substances across the cell membrane in favor of a concentration gradient.
The passive transport mechanism of FD is necessary only in the case of transport of very large molecules or polar molecules that:
Cannot be transported by simple diffusion, due to the selective permeability of the membraneThey follow a concentration gradient, from the place with the highest concentration to the one with the lowest concentration.For FD to occur, it requires the use of a protein, which acts as a carrier of the molecules to be mobilized.
The other options are not correct because:
A and C. Passive transport, as facilited diffusion, implies movement in favor of a concentration gradient.
B and C. Non-polar small or very small molecules can cross the membrane by simple diffusion.
With large non-polar molecules moving down the concentration gradient.

is the energy an object has because of the movement of its molecules.
A. Heat
B. Thermometer
C. Particles
D. Temperature
Temperature is a measure of kinetic energy because molecular motion is regarded as kinetic energy. The average kinetic energy of the molecules in a gas increases as its temperature rises, resulting in more motion. Thus option D is correct.
What is kinetic energy?A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
The molecular kinetic energy rises and the molecules start to move faster when heat energy is added to a system.
By increasing the temperature, the velocity of the particles is accelerated.
In contrast, lowering the temperature slows down the motion of the particles until it eventually stops entirely at absolute zero (0 K). The particles will have kinetic energy since they are moving.
Therefore, Temperature is the energy an object has because of the movement of its molecules.

What type of cell is c?
A)
animal
B)
bacterial
C)
Tungal
Eliminate
D)
plant
Answer:
D
Explanation:
Diagram C represents the structure of a plant cell. Thus, the correct option for this question is D.
What are the characteristics of a plant cell?Plant cells have certain distinguishing characteristics that may significantly include the presence of chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
Animal cells and bacterial cells do not have chloroplast thus they cannot perform photosynthesis (preparation of food with the help of sunlight, water, and carbon dioxide.) Within the cell membrane, reaction centers are present which absorb light energy.
Both photosynthetic bacteria and plants contain chlorophyll, but the types of chlorophyll differ in their structure. An animal cell is a type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles.
Therefore, diagram C represents the structure of a plant cell. Thus, the correct option for this question is D.

Jessica: Pitch is how high or low a sound is. The pitch depends on vibrations. High pitch sounds have low amounts of vibrations
Rachael: Pitch describes how high or low a sound is. Sounds are caused by vibrations. The more vibrations, the higher the pitch.
Harvey: Pitch is caused by vibrations. The more vibrations, the lower the pitch of the sound.
Derek Pitch is how high or low a sound is. All sounds have mostly the same pitch.
Who has the best description of pitch?
Jessica
O Rachel
O Harvey
O Derek
Answer: Rachel
Explanation:
Pitch indeed refers to the highness of lowness of a sound. We are able to sense pitch based on the frequency of the sound wave with a higher frequency (more vibrations) having a higher pitch and a lower frequency having a lower pitch.
This is why lighter strings on guitars produce a higher pitch because when struck, they vibrate more as opposed to heavier strings. Rachel is therefore correct.
