Answer:
a. lack of running water
Explanation:
The Tippy tap technology was invented to solve the issue of running water problem. This technology is designed mainly for hand washing and it is used in the rural area to solve the running water problem.
This technology technique needs only forty milliliters of water; it is less expensive and reduces the chance of transmitting diseases as the user only touches a bar of soap suspended by a string.
The correct answer is A.
The use of antibacterial drugs can cause modifications in the genetic material of the concerned bacteria. If the genetic material of the bacteria are modify, that means they have undergone mutation. Because the base sequence of the normal and that of the mutated gene is different, antibiotic will not be able to recognize the bacteria again and thus will not be able to attack it.
Answer:
1. opening Voltage gated channels
2. Calcium
Explanation:
The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.
The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.
The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.
Thus, opening Voltage gated channels and Calcium is the correct answer.
Answer:
Option (A), (B), (D) and (F).
Explanation:
Bacteria are involved in the domains of eubacteria and archaea. Bacteria are different from the other organism and shows different in the chemical and cellular structure of the cell.
The translation elongation factors are different in bacteria and other organisms. The translation factors of bacteria are EF-Tu and EF-Ts whereas the eukaryotic elongation factors are eEF-1 subunit α and eEF-1 subunit βγ. A single RNA pol is present in bacteria and three different RNA pol is present in eukaryotes. Peptidoglycan is present in prokaryotes. Phospholipids contain ester linkage in bacteria and ether linkage in archaea.
Thus, the correct answer is option (A), (B), (D) and (F).
