The oldest geologic strata and events are in the following order: C-1, D-2, B-3, A-4, and E-5.
A geological layer is what?
Layers of sediment are deposited on top of one another to create horizontal strata as a result of the processes that create sedimentary rock. As more recent sediments are deposited on top of older sediments, a natural timeline is created that enables scientists to estimate the relative ages of the various layers.
Each layer is composed of deposited sediments that were weathered and worn away from distinct rock sources, making it possible to distinguish between the different sedimentary strata when they are exposed. Due to the various compositions of the rocks, they appear to be various tints and/or colours. The rock layers were initially horizontal with the ground due to the gravity of deposition.

If a potassium leak channel inhibitor is applied to a culture of neurons the resting membrane potential would become more positively charged.
Since they control intracellular and extracellular ionic concentrations and produce resting or action potentials, ionic channels in neurons are essential. In contrast to the action potential, which always happens after this, the resting potential makes the neuron appear inactivated when conveying a signal and does not take stimuli from others. The resting potential would be extended and would possibly approach total rest for a long time if the potassium channels of a neuron were to remain closed. High levels of neuronal intracellular potassium prevent action potentials from being triggered, hence this neuron would not experience a membrane action potential, cause muscular contractions, or transmit signals.

how can variations in proteins between species be used to determine their evolutionary relationships?
Protein sequence similarities can be used to infer evolutionary relationships. The results are more trustworthy when the sequences being compared are longer.
This is owing to both statistical factors and the potential of convergent evolution, which does not imply common ancestry, in which small sequences or portions of a longer sequence may have developed towards a common goal (for instance, an enzyme active site).
A continuous pace of random mutations takes place. Based on the differences between the two protein sequences, it is possible to determine the time of divergence using this rate of change. It's called a molecular clock. Species divergence can be addressed using this information. Numerous organisms share conserved genes and the proteins they codify. Typically, these are proteins with functions in widely used metabolic and developmental processes. Given that they do not undergo fast evolutionary change, these conserved genes and proteins are the most helpful for establishing evolutionary links.

In the event that you water a solitary flower that isn't straightforwardly close to one more flower of a similar sort, that flower can copy, or "clone" itself. The clone is indistinguishable from the original flower.
To begin with, pick the flower you need to clone. Planting hybrid flowers is the smartest option, as they can clone themselves and likewise draw in the most extraordinary bugs to them. Then, at that point, find a spot on your island that is Not even close to some other plants. This is important, as the hybrid flower needs space to clone itself and NOT cross with different flowers.
Once planted, make a point to water your hybrid flower. Watering the flower sets off the hybrid cycle and since there could be no different flowers close to it for it to cross with, the flower ought to just clone itself over and over.
Animal Crossing players have had incredible accomplishment with this strategy. On the off chance that you plant a flower close by its other relatives it could cross with those and make hybrid flowers of a similar kind.
