Viruses lack the properties of living things:
1. They have no energy metabolism
2. They do not grow
3. They do not respond to stimuli
4. They do not reproduce independently- they have to replicate by invading living cells.
It is known as a concentration gradient which in diffusion will always flow from ares of high concentration to areas of low concentrations
So i believe the answer to this is A.
Hello,
Question:
Over time bacteria get used to anti bacterial medicine. Doing this can add symptoms and take away the easiest process of healing grout the human and destroying the bacteria.
Using complete sentences, explain how this speeds up the process of evolution in bacteria.
Answer:
Well, the reason medicine speeds up the evolution of bacteria because it needs to put the medicine ineffect for the vaccine to work properly. The faster it works the easier and less painful it will be for that person. Thats why when they go to hospitals they try to give treatment as fast and quickly as possible so there is no further damage. The medicine works almost instantly.
Edited Answer:
The reason bacteria can evolve faster because the DNA which is sharing which the evolution happen much faster, mostly because you don't have to rely on mutations.
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.
