What is transcription and translation?
The process of transcribing a piece of DNA into RNA is known as transcription. Messenger RNA is created when segments of DNA are translated into RNA molecules that can encode proteins. Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum create proteins following the transcription of DNA to RNA in the cell's nucleus. The entire process is known as gene expression.
What is cell membrane?

successfully growing). A soil ecologist was notified. She
immediately noticed that there were no worms, bacteria, or

Explanation:
The plants stopped growing, so I imagine the microorganisms moved to find a better food source.
Assume that a population of 50
individuals has the following numbers
of genotypes for a gene with two
alleles, B and b: BB = 30, Bb = 10,
and bb = 10. Calculate the
frequencies of the two alleles in the
bopulation's gene pool.
Answers
The population's gene pool, the frequency of the B allele is 0.7 (or 70%) and the frequency of the b allele is 0.3 (or 30%).
To calculate the frequencies of the two alleles (B and b) in the population's gene pool, we can use the allele frequency formula. The allele frequency is the proportion of a specific allele within a population.
Given the genotypes BB = 30, Bb = 10, and bb = 10, we can determine the number of alleles in the population as follows:
Number of B alleles = 2 * (number of BB genotypes) + (number of Bb genotypes)
= 2 * 30 + 10
= 60 + 10
= 70
Number of b alleles = 2 * (number of bb genotypes) + (number of Bb genotypes)
= 2 * 10 + 10
= 20 + 10
= 30
Next, we can calculate the frequencies of the two alleles:
Frequency of B allele = (Number of B alleles) / (Total number of alleles)
= 70 / (70 + 30)
= 70 / 100
= 0.7
Frequency of b allele = (Number of b alleles) / (Total number of alleles)
= 30 / (70 + 30)
= 30 / 100
= 0.3

The theory of endosymbiosis proposes that eukaryotes descended from a primitive combination of both archaea and bacteria. What evidence supports this theory?
Answers
The theory of endosymbiosis proposes that eukaryotes descended from a combination of both archaea and bacteria. Evidence that supports this theory includes the similarities between mitochondria and chloroplasts to free-living bacteria, the presence of double membranes around mitochondria and chloroplasts, and the fact that mitochondria and chloroplasts have their own DNA.
Explanation:
The theory of endosymbiosis proposes that eukaryotes descended from a combination of both archaea and bacteria. Evidence that supports this theory includes the similarities between mitochondria and chloroplasts to free-living bacteria, the presence of double membranes around mitochondria and chloroplasts, and the fact that mitochondria and chloroplasts have their own DNA.
Mitochondria and chloroplasts contain some of the same enzymes and transport systems as bacteria, and are similar in size and shape to bacteria. In addition, they both reproduce by binary fission, similar to bacteria. The presence of double membranes around mitochondria and chloroplasts also supports the theory of endosymbiosis, as this suggests that the organelles were engulfed by the host cell and retained their own membranes.
Finally, mitochondria and chloroplasts have their own DNA, which is circular like bacterial DNA. The DNA of mitochondria and chloroplasts also lacks histones, which are present in eukaryotic DNA, and is more similar to bacterial DNA in terms of gene expression and replication.
Together, these lines of evidence support the theory of endosymbiosis and suggest that mitochondria and chloroplasts were once free-living bacteria that were engulfed by a host cell and evolved into the organelles found in eukaryotic cells today.

O The higher water levels allow longer-legged birds to survive and reproduce.
O The water quality for feeding has been improved by runoff.
The reduced salinity results in more eggs being laid.
Answers
Answer:
Explanation:
The water cycle disruptions have most affected wading birds by:The release of water dilutes food sources for their young.This is because wading birds depend on the natural flow of water to bring in fish and other small aquatic organisms which are a vital part of their diet. When the water cycle is disrupted by the canals and levees, the water flow changes, and the amount and timing of these organisms can be impacted, making it harder for wading birds to find food for their young. Therefore, option (a) is the correct answer.Option (b) is incorrect because longer-legged birds are not necessarily more adapted to survive in higher water levels.Option (c) is incorrect because water quality may not necessarily improve due to runoff.Option (d) is incorrect because reduced salinity may not be a direct cause of increased egg-laying.

The graph below compares the rates of reaction of a burning candle and an exploding firework.
Comparing Chemical Reactions
A graph has time on the horizontal axis and concentration of reactants on the vertical axis. For an exploding firework, the concentration starts high, increases slightly and then decreases rapidly. For a burning candle the concentration starts high, increases more than the firework, and then decreases rapidly. The concentration for the burning candle is higher than the firework at all timepoints.
What can you conclude from the graph?
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Answers
Answer:
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Explanation:
The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.
Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.
In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The rate of reaction refers to the ease with which reactants are converted to products. The higher the rate of reaction, the faster reactants are converted into products.
The activation energy is the energy required for reactants to be converted into products. It is an energy barrier that separates reactants and products.
From the description of the graphs, we are told that the reaction that causes the explosion of firework starts at high concentration, initially increases slightly then decreases rapidly. The fact that it initially increased slightly before decreasing rapidly implies that the high energy required for the reaction to start is high.
On the other hand, the reaction for the candle to burn starts at high concentration, increases more than the firework, and then decreases rapidly because the reaction requires a lesser energy to commence than the reaction for the burning of candle.

What is Y-Linked inheritance?Y-linked inheritance is a type of genetic inheritance that occurs exclusively through genes located on the Y chromosome. The Y chromosome is one of the two sex chromosomes in humans, and it is typically only present in males.
Since females do not have a Y chromosome, they cannot inherit traits that are exclusively Y-linked. In males, however, any genetic variation on the Y chromosome is passed on directly from father to son.
Y-linked inheritance is relatively rare compared to other types of inheritance because the Y chromosome is small and contains relatively few genes. Some examples of traits that are known to be Y-linked include male-specific infertility, hair loss, and some types of color blindness.
