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.

It is the property by virtue of which the genes from parents are expressed into the individuals in the progeny.
When one allele is not completely dominant over the other and the result is a blended phenotype. For example, RR is red, rr is white, Rr is pink the dominance in it is called the incomplete dominance.When there are more than two alleles for a gene it is called as multiple alleles.
When there are two alleles that are equally dominant and both traits are expressed independently in the phenotype. For example, RR is Red, rr is white, Rr is red and white it is called as co dominance where the both are expressing.

OC. Prokaryotes do not have mRNA, so there are no codons.
O D. Codons are very similar, no matter whether the cell is prokaryotic or eukaryotic.

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.

What do muscle cells in oxygen deprivation gain from the conversion of pyruvate?
A process called lactic fermentation takes place inside the muscle cells when they are deprived of oxygen. Pyruvate is turned into lactic acid. 2 moles of ATP are gained from this reaction
Muscle cells in oxygen deprivation conditions will produce lactic acid and energy from the conversion of pyruvate.
What is Oxygen deprivation?Oxygen deprivation may be defined as a circumstance in which an extreme reduction in the concentration of oxygen in the body is accompanied by an increase in the concentration of carbon dioxide. It is a condition sustained due to a lack of oxygen.
When there is a lack of oxygen occurs in the muscle cells, the pathway for the breakdown of pyruvate takes place. During which pyruvate is converted into lactic acid along with the liberation of energy.
This accumulation of lactic acid in your muscle cells during sudden activity causes cramps. This breakdown of pyruvate is a unique process that only takes place in the absence of oxygen in the muscle cells.
This process of breakdown of pyruvate into lactic acid is known as anaerobic cellular respiration.
Therefore, muscle cells in oxygen deprivation conditions will produce lactic acid and energy from the conversion of pyruvate.

B)

C)

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.

___ 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.

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.
