Answer:
It spreads by conjugative plasmid.
Explanation:
Bacterial population spreads their antibiotic resistance by conjugative plasmids, a circular DNA with locus for partitioning and origin of replication. Conjugative plasmids exist naturally in bacteria. Normally they multiplyand live inside the cells, using their synthetic machinery, but can also transfer its genes to neighbouring cells. It is this characteristic that causes rapid antibiotic resistance in bacterial population even if those bacterial species are not related to each other.
Answer: when conditions for survival are unfavorable
Since there is two organism involved, sexual reproduction also increase the genetic variability of the population. This makes the population could adapt in wide condition. When the condition of the habitat changes and make survival is harder for general population, there might be someone with genetic variability that become favored instead.
Answer:
Plant biotechnology can be defined as the use of tissue culture and genetic engineering techniques to produce genetically modified plants that exhibit new or improved desirable characteristics.
Explanation:
These crops offer several benefits both farmers and consumers.

Answer:
is there supposed to be a picture
6.941 tells you the nucleon number (total number of protons and neutrons in the nucleus of an atom)
3 tells you the proton number( number of protons in the nucleus of an atom.)
When drawing this you must know the number of protons , electrons, and neutrons of that element. Well in this question, everything’s been given. No. of protons = 3
No. Of electrons = 3 *REMEMBER, NUMBER OF PROTONS AND ELECTRONS ARE EQUAL WHEN THE ELEMENT IS IN ITS ATOMIC FORM.
No. Of neutrons= 4 neutrons. When rounding 6.941, it is 7. Then simply subtract 7-3 to get 4.
Now time to draw this. First you must know the number of electron shells does lithium has. Since lithium is in period 2, it has 2 electron shells.
Then, you must know what is the valence electron of Li. It is 1, since it is a group I element/alkali metal.
Also remember the structure. Electron are surrounding the nucleus of the atom on electron shells while the nucleus is in the center of the atom. Nucleus contains the protons and neutrons. REMEMBER THE FIRST SHELL SHOULD CONTAIN ONLY 2 ELECTRONS WHILE THE SECOND SHELL WITH 8 ELECTRONS AND GO ON.
Hope this helps and if I’m correct can you add me to the brainliest?
