Answer:
Hail.
Precipitation is also known as rainfall and it is important as a way of balancing and regulating the earths atmospheric conditions. Precipitation could involve rainfall, snow or hail.
Hail is usually accompanied by a storm which produces precipitation in the form of ice particles. This happens when the dew point is below freezing which results in the formation of ice crystals.
The first life on Earth wasA. prokaryotic.B. eukaryotic.C. prokaryotic and multicellular.D. eukaryotic and multicellular.E. eukaryotic and unicellular.
The first life on Earth was prokaryotic. There're different theories about the origin of these kinds of cells, among them we can find how it's hypothesized that these basic forms of life came up from other planets in meteorites, what it's known as the panspermia theory of life. On the other, there's said that the primitive conditions after the formation of our planet gave place to cyclic inorganic molecules that replicate themselves in a physicochemical equilibrium, as happens today with the nutrients cycle, for example, and in a primordial soup, these replicated molecules began to conform more complex structures like nucleic acids that lead to the formation of live organisms. Maybe they resulted after those basic molecules were progressively being part of other molecules, and involved other molecules in their basal structures, such as states the endosymbiotic theory. Or maybe the origin of those basic forms of life is the result of these and other theories in conjunction .

whats Part of the neuron that receives messages
The part of the neuron that receives messages are called Dendrites .
Dendrites are the branching, tree-like structures that extend from the cell body of a neuron. They are specialized for receiving signals from other cells, such as other neurons, and for transmitting signals to the cell body. They are typically composed of an array of tubular structures known as microtubules and contain a variety of protein molecules that allow them to detect and process signals. Dendrites are essential to neuronal communication, as they allow neurons to receive information from other neurons and integrate this information with the neuron’s own activity.
Therefore, the dendrites are the part of the neuron that specialize in receiving messages from other neurons.

The plant should completely stop manufacturing high-energy sugars, as expected. Due to the fact that photosynthesis requires CO2, a plant without CO2 will not be able to produce energy and would most likely perish.
What is meant by photosynthesis ?Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that may then be released through cellular respiration to power the organism's activities. The word "photosynthesis" comes from the Greek words "light" and "putting together," and refers to the process of creating molecules of carbohydrates from carbon dioxide and water. These molecules, such as sugars and starches, are then stored with some of this chemical energy. Photoautotrophs are creatures that perform photosynthesis, including most plants, algae, and cyanobacteria. The majority of the energy required for life on Earth is produced and maintained through photosynthesis, which is also substantially responsible for creating and maintaining the oxygen concentration of the atmosphere.Learn more about photosynthesis refer to :

Cocaine causes the neurotransmitter dopamine to remain at the site of the synapse longer than it normally would; cocaine thus inhibits the process termed:
Cocaine inhibits the process of reuptake.
Reuptake is the process in which neurotransmitters are taken back up into the presynaptic neuron after they have been released into the synapse. This process helps to regulate the level of neurotransmitters in the synapse and maintain proper neuronal function. Cocaine works by blocking the transporter proteins that are responsible for the reuptake of dopamine, causing it to remain in the synapse longer than it normally would. This leads to an overstimulation of the dopamine receptors, which can cause the feelings of euphoria and increased energy associated with cocaine use. However, over time, this prolonged exposure to dopamine can lead to changes in the brain's reward circuitry, contributing to addiction and other negative consequences of cocaine use.

Which statement correctly describes the transfer of energy between the blue arrows?
O There is no change in energy.
There is twice the gain of energy.
There is a loss of energy.
There is a gain in energy.
The blue arrows denote the direction of the energy transfer from the turbine to the electrical generator. Based on the given diagram, the energy transfer between the blue arrows is a gain in energy.
Energy transfer refers to the conveyance of energy from one form to another, such as mechanical energy into electrical energy. Therefore, there is an increase in energy between the turbine and the electrical generator, which is highlighted in the blue arrows' direction.
The generator gains energy in the form of kinetic energy from the turning motion of the turbine. When the turbine turns the shaft of the generator, it causes electromagnetic fields to occur within the generator, which, in turn, generates electricity.
This energy transfer process is efficient as long as the system does not face friction or other forms of resistances. If the system does face such resistances, then there is a loss of energy and inefficiency in the energy transfer process, which can significantly affect the system's overall performance.
In conclusion, the energy transfer between the blue arrows is a gain in energy. The generator gains energy in the form of kinetic energy, which is converted into electrical energy. The efficient energy transfer process is vital for the system's optimum performance and operation.

Why don’t populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexually
Answer:
Asexual reproducing populations only get their genetics from a single parent, meaning that they all have the exact same DNA/RNA, while sexually reproducing populations have two parents meaning they get genetic code from two parents instead of one, therefore they have more variance. This variance is also the reason sexually reproducing populations are usually harder to wipe out due to variance.
