The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
Answer:
several transcription factors (TFs)
Answer:
C. Nernst equation
Explanation:
The Nernst Equation is used to find the equilibrium potential of an ion.
It tells you only what the equilibrium potential for an individual ion is, not what the summed effect of all ions is on the membrane potential.
The formula for Nernst Equation is:
=
In
where F is Faraday Constant, R = gas constant, 8.314 J/mol K
, T = temperature, in K, Z stoichiometric number of electrons in the reaction, is the Reduction Potential in V.
Kindly note that, if we have a squid giant axon at rest with normal intracellular and extracellular ion concentrations. If the membrane permeability to K+ ions is increased, the K+ equilibrium potential (Nernst potential) will stay the same.
Following are the steps to be taken while handling chemicals with precautions:
1. Application of droppers to transfer small amounts of chemicals into another glassware, as it will inhibit the unwanted overflow of the chemical.
2. Check the test tubes for chips before using them, otherwise, it may leak the chemicals within them.
3. Application of tongs to move the hot components as they may even result in extreme burns.
4. Washing the hands after concluding the lab experiment is necessary, as it will make sure that the food does not get intoxicated with the chemicals present in the hands.
