it involved in the transfer of genetic material from one cell to another.
Answer:
The trait must make the individual more fit to survive. True
Explanation:
Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.
The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.
K represents potential energy
A natural gas stove transforms R energy into P energy. What do R and P most likely represent? A.) R represents chemical energy, P represents thermal energy R represents thermal energy, P represents chemical energy ,
R represents electrical energy
Answer:
shells 1, 2 and 3 are full and shell 4 has one electron
Explanation:
The distribution fo the electrons possessed by an atom in the shells surrounding it is termed as its electronic configuration.
According to the rules of writing the electronic configuration:
1. The first shell can be occupied by a maximum of two electrons.
2. the subsequent shells can be occupied by a maximum of 8 electrons.
3. the subsequent shells are filled only once the lower shells have been filled.
Based on these rules, the electronic configuration of potassium should be 2, 8, 8, 1. (2+8+8+1 = 19).
Thus, we can see that the first three shells are filled, and the last one has one electron left.
The answer is SPORES.
Some bacteria, take for example clostridium can be killed with heat but still leave their spores.
They are heat-resistant spores that may survive cooking and later grow and produce large numbers of cells if the storage temperature is appropriate for their growth.
