Step 3: Mix the foreign DNA with chopped plasmids.
Step 4: Add DNA ligase.
Microscope to focus on a specimen identify one safety issue to consider
Answer:
Option 3, of the abiotic factors found in their environment
Explanation:
The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.
The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case, if a bacteria lives in an environment where temperature is less than -5oC or higher than 50oC, then such habitats are considered to be “habitats with extremities” as special physiological mechanisms are required to maintain the homeostasis and survive.
Likewise absence of sunlight further adds to the extremities of the habitat.
Option 3, is correct
Active transport is a cellular transport mechanism. It’s the movement of molecules that are assisted by enzymes along the way to a higher concentration.
Answer:
true
Explanation:
the equator is warmer than the poles because the equator is significantly closer to the sun than are the poles (i.e. the equator "bulges out" toward the sun)
