Answers
-The Submandibular Ganglion is the ganglion that provides postganglionic parasympathetic innervation to the submandibular and sublingual salivary glands to augment their secretions.
-The human autonomic nervous system includes the submandibular ganglion, often known as the submaxillary ganglion in earlier sources. It belongs to the head and neck's four parasympathetic ganglia. (The otic ganglion, pterygopalatine ganglion, and ciliary ganglion are the others.)
Where is it found?
Little and fusiform in shape, the submandibular ganglion is modest. It is located on the hyoglossus muscle, close to the posterior border of the mylohyoid muscle, over the deep part of the submandibular gland.
The ganglion "hangs" from the lower border of the lingual nerve by two nerve filaments (itself a branch of the mandibular nerve, CN V3). Two anterior and two posterior filaments support it from the lingual nerve. It receives a branch from the chorda tympani nerve, which runs in the sheath of the lingual nerve, through the posterior of these.
Fibers:
The submandibular ganglion, like other parasympathetic ganglia of the head and neck, serves as the synapse for parasympathetic nerve fibres as well as carrying other types of nerve fibre that do not synapse in the ganglion. The following is a list of the fibres carried in the ganglion:
sympathetic fibres from the face nerve and its branches, which travel through the external carotid plexus. In this ganglion, they do not synaptize.
Preganglionic parasympathetic fibres from the superior salivary nucleus of the Pons travel to this ganglion through the chorda tympani and lingual nerve.
salivary glands of the submandibular, sublingual, and oral mucosa are all served by postganglionic parasympathetic fibres. They act as these glands' secretomotors. After re-entering the lingual nerve, some postganglionic fibres travel to the sublingual gland.

______ summation results when EPSPs occurring at multiple synapses add up to threshold at the axon hillock.
Answers
Spatial summation results when EPSPs occurring at multiple synapses add up to the threshold at the axon hillock.
Spatial summation occurs when excitatory postsynaptic potentials (EPSPs) from multiple synapses combine to reach the threshold for generating an action potential at the axon hillock. This process involves several presynaptic neurons simultaneously releasing neurotransmitters, which then bind to the postsynaptic neuron's receptors.
The combined effect of these EPSPs increases the likelihood of an action potential being generated. Spatial summation is essential for proper neural integration and communication, as it allows for the integration of information from multiple sources and the generation of appropriate responses.
In summary, the spatial summation is the result of multiple EPSPs occurring at various synapses adding up to reach the threshold at the axon hillock.

Create an argument to support the claim made in the readings that jade plants have properties that allow them to survive long dry spells. Cite reasons and evidence from the texts to support the claim. Also cite what you may already know about succulents to support the claim
Answers
The claim made in the readings that jade plants have properties that allow them to survive long dry spells can be supported by several reasons and evidence from the texts.
Firstly, jade plants belong to the succulent family. Succulents are a group of plants that have adapted to survive in arid environments with little water availability. They store water in their leaves, stems, or roots, allowing them to withstand long periods without rainfall. This ability to store water is a key adaptation that enables succulents, including jade plants, to survive in dry spells.
Additionally, the text may provide evidence of specific characteristics of jade plants that contribute to their ability to survive in drought conditions. For example, the text may mention that jade plants have thick, fleshy leaves that can store water. These leaves have a waxy coating that helps reduce water loss through evaporation. This adaptation allows jade plants to retain moisture for extended periods, even in dry conditions.
Furthermore, jade plants often have shallow root systems that spread out horizontally rather than deeply into the soil. This helps them capture any available rainfall quickly and efficiently. The shallow roots also allow them to absorb moisture from the air when it is present, further supporting their survival during dry spells.
Considering what we may already know about succulents, we can further support the claim. Succulents, including jade plants, have evolved to survive in harsh, arid environments where water is scarce. Their ability to store water in their tissues and their efficient water-use strategies make them well-equipped to withstand prolonged dry spells.
In summary, jade plants possess several characteristics that allow them to survive long dry spells. These include their succulent nature, which enables water storage in their leaves, stems, or roots, as well as their ability to reduce water loss through waxy leaf coatings. Their shallow root systems and efficient water-use strategies also contribute to their survival during drought conditions.

Answers
The number of cells counted for the second hemocytometer image is required to determine the original cell concentration and the volume needed to obtain a specific cell count.
To calculate the original cell concentration, we need to consider that the cell suspension has been diluted 10-fold. The number of cells counted in the hemocytometer image represents the diluted concentration. By multiplying the counted cells by the dilution factor (10), we can determine the original cell concentration.
To calculate the volume of the cell suspension needed to obtain a specific cell count, such as 2×10⁶cells, we can use the formula:
Volume = Desired cell count / Original cell concentration
By plugging in the values, including the desired cell count and the previously calculated original cell concentration, we can determine the volume of the cell suspension required to achieve the desired cell count.
These calculations are crucial in cell culture and experimental procedures, as they allow researchers to accurately determine cell concentrations, adjust volumes, and ensure consistent cell seeding for various applications.

Daphnia is an acuatic microarthropod which depends on the environment to perform its metabolic tasks. Arthropods are poikolotermic, which means their body temperature depends in the environment's temperature. Considering the above, it would be important to measure the following variables for some period fo time, let's say 90 days: 1) temperature, 2)salinity, 3)organic matter and 4) pH. Number of days is important, so we could give Daphnia time to acclimate to its new environment. We should measure at least to points, in the beginning, to measure the immediate to response to the abiotic change, and at the end, to measure the effect of the measured variable in Daphnias heart.
The design could comprise treatments with normal values of this variables where Daphnia lives, and with a couple of extreme values (both upper and lower extremes. For example, imagine Daphnia uses to live in lakes with mean temperature of 19 C, then this would be the control case for temperature and you could also use 14 C and 24 C, as the treatments to explore the effects of temperature variation. In any case the choice of values should be informed by literature. For example with ongoing climate change, you could use the projected rises in temperature to explore how Daphnia would perform in those cases. After performing the individual variable assays (I mean, temperature fluctuates, the rest of parameters are hold the same). It would be pretty informative to combine variables. Let's say, how could Daphni behave with warming and acidic pH. Another example, how could Daphnia behave with warming and organic matter enrichment/oligotrophy (poor concentration of nutrients). In this way you could asses more realistic scenarios, since nature has these and much more variables playing simultaneously. According to the problem, heart rate is the variable of interest (that is of our response variable), therefore we should measure heartrate in all the conditions mentioned above. As all organismis search to keep their metabolism/functions (that includes heart rate, among many other) with major changes, we should see some fluctuations in the begginng of the assay, but their will tend to stabilize if Daphnia is able to cope with the altered environment conditions.
A hydrate is a compound that includes water molecules within its crystal structure.

Answers
The percentage by mass of water in the crystal would be 9.8% Correct option (2)
Mass of hydrated crystal = 4.10 grams
Mass of crystal after heating to constant mass = 3.70 grams
The heating must have removed the water. Thus, the mass of water can be calculated by removing the mass of the crystal after heating to constant mass from the hydrated mass.
Mass of water = 4.30 - 3.70

Explanation:
I took the test and got a 100%
Large, shaggy, prehistoric elephants known as woolly mammoths flourished throughout the Pleistocene Epoch (between 2.5 million and 11,700 years ago). Because they were adapted to dwell in cold regions and could not thrive in the warmer climate 16,000 years ago, woolly mammoths were forced to migrate north as North America's climate warmed.
The flora that woolly mammoths relied on for sustenance decreased in abundance as the climate warmed, making it harder for them to stay alive in their current habitats. As a result, they were compelled to move to locations farther north where the climate was still favourable for their existence.
