Viruses is what falls into the grey area of living and nonliving
Answer:
They are bilaterally symmetrical and have a soft body sometimes covered with a shell.
Explanation:
Mollusks are bilaterally symmetrical organisms which means only two planes can divide their bodies into two identical halves. They are triploblastic organisms with organ system level of body organization. Mollusks have a soft body that is usually covered by a dorsal shell composed mainly of calcium carbonate. The foot is a broad, flat and muscular structure located ventrally. Foot serves these organisms in locomotion. The various body organs are present as visceral mass located above the foot. The visceral mass is covered by a thin sheet of tissue called mantle. Example: clams, snails, and squids.
Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

The butterfly finds flowering plants for nectar in the meadow. In the process of sucking nectar, they pollinate the plants. The meadow plants such as grasses, forbs and sedges plants provide food for field mice that eat their leaves , roots, and bulbs. The mice also create burrows in the meadow where they breed their young. This, therefore, provides a good hunting ground for owls that prey on mice.
Because through natural selection, only the fittest survive. when the fittest come together and reproduce then the species continues and evolves with only the fittest and strongest genes.
