<u>Answer:</u>
Better spreading of reproductive cell is not a benefit of bioflims for bacteria.
Option: (d)
<u>Explanation:</u>
- Bioflims can allow for adhesion of colonies, that can attach surface such as rock, tooth and it includes single or group of micro organism.
- Bioflim bacteria can share 'nutrients' and it is sheltered from 'harmful factors' in environment like desiccation, antibiotics, etc.
- It allow resistance for sanitation, that hold bacteria together and also exclude most disinfectant and antibiotics. It is resistant to sterilization.
Answer:
The presynaptic membrane is formed by the part of the presynaptic axon terminal forming the synapse and that of the postsynaptic neuron is called the postsynaptic membrane. The space between the presynaptic and postsynaptic membrane is called the synaptic cleft. These three structures together form the synapse.
Explanation:
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
you need to ask a hypothesis
