Which is a reason that explains why DNA replication occurs in a continuous fashion on one parental DNA strand and in a discontinuous fashion on the other parental DNA strand
The reason that explains why DNA replication occurs in a continuous-discontinuous fashion is that DNA polymerase only works to add nucleotides in one direction of the growing chain.
Whta is DNA replication?DNA replication refers to the process by which the genetic material is replicated before cell division.
DNA replication involved specific enzymes that work in a concerted manner to replicate DNA molecules.
DNA polymerase is a specific enzyme used during DNA replication to add nucleotides in direction 5' to 3', which is the direction of the growing chain.

Please help: Does diffusion require energy?
Diffusion is a form of passive transport, which implies that it does not require the use of energy. Diffusion is defined as the movement of particles from an area of higher concentration to an area of lower concentration. In other words, particles experiencing diffusion move “down their concentration gradient."

what's a punnet square? The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.All possible genotypes for the haploid female gametes are listed across the top, one genotype at the head of each column; and down the left side of the square, all of the possible genotypes for the haploid male gametes are listed, one per rowI just made her answer much longer
Mollusk fossils were excavated and collected from a coastal cliff. Scientists studying the fossils observed patterns of changing shell shape in the mollusks. The scientists identified a period of stability or stasis, followed by rapid change, and then stasis again with regard to shell shape. Which of the following statements best predicts the result of a comparison between the fossils found before and after the period of rapid change?
a) The same species will be found in both static periods, but they will have different shell shapes.
b) The same species will be found in both static periods, but the species in the second static period will have smaller shells due to the stress of undergoing capid change
c) Most of the species found in the first static period will be absent in the second static period.
d) Most of the species found in the second static period will resemble each other more than the species found in the first static perlod
The statement that best predicts the outcome of a comparison between fossils found before and after the period of rapid change is that the same species will be found in both static periods but will have different shell shapes.
How does the evolution of species work?For Lamarck the evolution of the species occurs due to the modifications that are imposed by the environment in which they live. New characteristics are acquired by the repeated use or disuse of an organ or body part. Defines that, according to the use of a particular member, it would be developed.
With this information, we can conclude that the statement that best predicts the outcome of a comparison between fossils found before and after the period of rapid change is that the same species will be found in both static periods, but will have different shell shapes.

Based on the information in this table, the daily waste remained the same but the total waste has steadily increased. What are some possible explanations for this?
Hint: Think about population growth and its effects on the planet.
Answer:
With the growth of the population, the amount of waste produced rises. These two factors are correlated because despite the average amount of waste per day being produced per day stays the same, there are more people to create this waste, thus causing more waste per year. For example, if you had 4 friends and 20 candies between you, then the total candies is 20, and the average person gets 5 pieces. If you had 5 friends and 25 candies the next day, then the total amount of candies you have increases, but the average amount each person gets stays the same (5).
The daily waste remained the same but the total waste has steadily increased due to an increase in the population.
From the information that's given in the graph, we can infer that the increase in the population led to an increase in the total waste. In this case, the total waste in millions of tons per year will increase.
Despite that, the daily waste which is the pounds per day per person can still be the same. For example, let's say the population before was 100 people and the total waste was 2000 tons. Then the waste per person will be:
= 2000/100 = 20 tons per person.
Now let's say the population increases to 110 people and the total waste then increases to 2200 tons, then the waste per person will be:
= 2200/110
= 2 tons per person.
The above shows that despite the fact that there's an increase in total waste, the daily waste is still the same.
