<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Answer:
It is important to use the regulatory sequence of a milk gene when constructing a recombinant gene used to produce a human protein secreted in milk because<em> it is capable of increasing or decreasing the expression of specific genes within an organism.</em>
Explanation:
<em>Regulatory Sequence</em> is<em> a segment of a nucleic acid molecule</em> which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses.
Protists are eukaryotic organisms that do not plant, animal, or fungus.
The kingdom Protista includes an organism that can survive by photosynthesis in the presence of light or by consuming organic material in dark conditions.
<h3>What are protists?</h3>
Protists are eukaryotic organisms.
The nutrition present in them is mixotrophic.
Some organisms make food through photosynthesis and some are parasites and some consume organic material.
Thus, the correct option is protists, they can survive by photosynthesis in the presence of light or by consuming organic material in dark conditions.

Gestational age can also be estimated by measuring the fundal height. This is done by measuring from the pubic bone to the top of the uterus. The measurement in centimeters roughly equal to the gestational age in weeks from the last menstruation.
