Bacteria exposed to DNA can incorporate the DNA and change phenotype.
Hope this helps.
Have a nice day.
The clear explanation for the forces mentioned in the question given below
Explanation:
1.A non-contact force that is generated between charged objects is known as "Magnetic force" eg: train tracks, new roller coaster, a compass, motor.
2.A non-contact force that is generated from moving charges is known "Electrical force". eg: Electric charge in a bulb.
3. A non-contact force that exists between objects with mass is known as "Gravitational force". eg: The force that causes apple to fall down from trees, The force thatt makes us to walk instad of floating.
4.A force that requires physical contact between objects is known as "Contact force". eg: moving a chair or table across a room, kicking a ball
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Answer:
by lowering activation energy.
Explanation:
Virtual Access to images of mars will help kids better understand science because they get to see what life is like on planets, other than the one they live on. It’s a great educational experience, they get to compare and contrast things from where they are to Mars. Hey
Hope this helps! :)
