[tex]\Huge\text{1) Sensory Neurons}\\\\\Huge\text{2) Synapse}[/tex]
_____________________________________[tex]\Huge\textbf{Reflex Action:}[/tex]Reflex action is a involuntary and instantaneous action in response to a stimulus acting over a reflex arc. Some reflex actions are inherited and innate while other are acquired through learning processes. These reflex actions are performed without the will of the animal & generally involve minimum number of neurons.
Reflex Arc:Many neurons work in group called reflex arc, There must be atleast two neurons in a reflex arc. A reflex arc is made possibly a shortest pathway so the body acts on an impulse before it reaches the brain, and usually it is coordinated by spinal cord and brain-stem.
The parts of reflex arc is given as,
A receptor, a sense organ in the skin muscle or other organ.An afferent or sensory neuron, which carries impulses towards the central nervous system.The central nervous system, where a synaptic connections are made between the sensory neuron and the inter-neurons.The efferent or motor neurons which makes a synaptic connection with the inter neuron and carries impulses out from the central nervous system.The effector, by which the animal responds to the environmental changes.The change in the body is detected by receptors which gives the information to the brain or spinal cord which is the control center via the sensory neuron. The control center decides the appropriate response and sends it to the effector via motor neuron which plays its role.
_____________________________________[tex]\Large\textbf{Synapse:}[/tex]
a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells or the muscle.

The one variable affects another happens in experiments. Thus, option D is correct.
What is experiment?An experiment, or experimental research, is a research method in which the researcher manipulates or changes the value of one variable, (the independent variable) and measures the variable that is considered the dependent variable, in order to find how the change affects it.
The other three posible answers, observational research, survey and case study are also research methods, but the researcher can't manipulate or control any of the variables, these methods are used only to measure a specific variable.
Therefore, The one variable affects another happens in experiments. Thus, option D is correct.

Answer:
The correct answer is - prokaryotic and unicellular.
Explanation:
Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.
These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
What is the greenhouse effect?
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?
IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET
Answer:
sugar
Explanation:
sugar is the required macromolecule
In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.
What is the main ingredient for lactic acid fermentation ?It is the sugar molecule that is needed for the lactic acid fermentation.
Both the types of the fermentation requires two primary components which are a sugar supply and bacterial culture where alcohol fermentation uses the forms of the yeast where the lactic acid fermentation usually depends on the lactic acid bacteria.
Lactic acid fermentation takes place in some of the strains of the bacteria and in the even skeletal muscle and even produces lactic acid . Alcoholic fermentation takes place in the yeast and just produces ethanol with carbon dioxide.
Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the strong tolerance to low pH.

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?
Answer: The removal of portions of RNA known as intervening sequences (introns)
Explanation:
The removal of portions of RNA is known as intervening sequences (introns).
What is the process of splicing?In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.
Intron sequences are cut out and exon sequences are joined during the splicing process.
As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.
In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.
Therefore, the removal of portions of RNA is known as intervening sequences (introns).

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.
Explanation:
As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.
