Answer: Option D
Explanation:
The bacteria can undergo cell differentiation in response to the environmental conditions.
The oxidative stress, antibiotic exposure, stress conditions are some of the external conditions due to which the bacterial cell can respond in the cell differentiation.
The bacterial species can divide based in the conditions in which they are put. So it is true that under stress conditions the bacterial cell can undergo cell differentiation.
Plants living in dry areas face conflict.
EXPLANATION:
- Since they live in dry areas they will undergo more transpiration.
- If they open stomata during the day there will be excessive loss of water vapor that will result in their death.
- Therefore plants living in this area open the stomata during the night to obtain Carbon dioxide.
- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
Answer:
R = 480 Ohm
Yes, the current is steady since the power supply is a constant 12V (comming from the battery).
Explanation:
U=I*R
R = U / I
U = 12 V
I = 0.025 A
R = 12 / 0.025
R = 480 Ohm
Answer:
<u><em>The correct option is C) Prions</em></u>
Explanation:
Bovine spongiform encephalopathy (BSE) or Mad Cow Disease is a disease which occurs due to transmissible particles known as prions. Prions cannot be considered as living organisms as they do not acquire many of the living characteristics. They are just considered as a protein which gest converted into an activated, toxic form as soon as they encounter a host cell. This toxic protein harms the central nervous system (CNS) of the cow host and is transmissible.
