<span>The question above is incomplete, the remaining part of the question is given below:
1. Since more offspring are produced
than an environment can support, organisms within a population must compete for
resources to survive.
2. Due to variations within the population, some competitors will be better
equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped
offspring.
4. Variations that help with survival will be passed on to future generations
and will rapidly change the whole population.
Which point is flawed as written above?
A. point 1
B. point 2
C. point 3
D. point 4</span>
ANSWER
The correct option is D.
All the options written above about Darwin's theory are quite correct with the exception of option D. Charles Darwin was the scientist who proposed the theory of evolution by mean of natural selection. Darwin submitted that, due to the scarcity of needed resources in an environment, it is only the fittest individuals in a particular population that will be able to survive and produce offspring that share their adaptability features. As this continue from generation to generation, it leads to evolution, which is defined as the changes overtime, which give rise to new species that share a common ancestors. Contrary to the point made in option D, evolution by natural selection is not a rapid process at all, it is a process that occur over a long period of time.
Answer;
-Bone tissue becoming stronger.
The mechanical stress applied to bones during moderate physical exercise leads to bone tissue becoming stronger.
Explanation;
-Bones and muscles both become stronger when muscles push and tug against bones during physical activity.Swimming and bicycling are not weight-bearing activities, so they do not directly help build bones. But swimming and bicycling do help build strong muscles, and having strong muscles helps build strong bones.
-Weight-bearing physical activity causes new bone tissue to form, and this makes bones stronger. This kind of physical activity also makes muscles stronger. Bones and muscles both become stronger when muscles push and tug against bones during physical activity.
An example of vesiscle-mediated transport would be cell secretion by exocytosis.
The reason why this would be an example of vesicle-mediated transport is because all the other types of transport listed here are not something you would call vesicle-transport; the substances don't really get transported in vesicles. This is different in exocytosis where the compounds gets packaged into vesicles.
