Answer:
Dissociation of actin subunits occurs.
Explanation:
When we add phalloidin to a solution containing G-actin, the phalloidin binds to actin filaments more tightly as compared to actin monomers which leads to a decrease in the constant rate of dissociation of actin subunits from the ends of the filament. This dissociation stabilizes the actin filaments through the prevention of filament depolymerization. So we can conclude that addition of phalloidin to actin leads to stabilizing of actin filaments.
Answer:
Mutation.
Explanation:
Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.
The correct answer is A. 20.2 s
Explanation:
The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:
20 + 19.2 + 21.5 = 60.7 - Results of each of the trials
60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials
This means the average time for the toy to move on dirt was 20.2s
Molecules are moving because they have energy. As the liquid cools down, the amount of energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. Even in this solid stage, the molecules are still moving – we just can’t see it.
The process of development of adults from the unfertilized egg is known as parthenogenesis. Parthenogenesis occurs in insects such as bees, wasps and bumble bees. Normally, males are produced in these insects. The individuals develop from unfertilized eggs and contain the single (haploid) set of chromosome.
