population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred
A natural disaster.
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.
Answer:

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%
Answer:
The correct answer is - 25%
Explanation:
A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.
The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.
So the probability of short allele would be:
= (2/8) *100
= (1/4) *100
= 25%
Hereditary fructose intolerance is a genetic condition caused by a variant in the ALDOB gene, which is critical for fructose metabolism. Infants with this condition do not initially display symptoms, but as they are transitioned from breast milk or formula to solid foods, in particular fruit-based foods, they begin to display symptoms, which include vomiting, diarrhea, and low blood sugar. Individuals who do not consume fructose do not display these symptoms. Which of the following describes this condition?
a. It is incompletely penetrant, due to environmental factors.
b. It has variable expressivity, due to environmental factors.incorrect
c. It is incompletely penetrant, due to genetic factors.
d. It has variable expressivity, due to genetic factors.
It has variable expressivity due to the environmental factors.
The variation in expressivity occurs due to the environmental factors of that individual. Expressivity describes the differences observed in the phenotype between two individuals that belongs to same genotype.
In the condition, when the patient is allowed to consume the fructose based food, so it expresses the change in its body due to no tolerance against fructose so we can conclude that the change occurs due to environment not due to genetics.

Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

Why is it important to have a taxonomy or classification of types of collection and how does that help us understand the development of collection strategies, technologies, collection planning, and methods of collection
Answer:
Classifying and characterizing various types of collection helps us to identify and understand the capabilities and limitations of each type.
Explanation:
By understanding these factors, we are better able to request support, layer collections, and provide a complete collection plan that best addresses our intelligence gaps. Collection strategies ultimately start with these gaps. By understanding all of your available collection capabilities, you can more effectively manage these assets to accomplish the mission. In most cases, you will not be able to have every type of asset or collection medium under the sun, so it becomes even more critical to understand the strengths and weaknesses of those available. Doing so will help a collection manager most effectively utilize the assets available to them to accomplish the collective organizational mission or end state. Without characterization and classification, you cannot fully understand and thus employ the myriad of tools available effectively (Found on a site not mine)
Taxonomy allows us to organize and categorize collections based on their characteristics, which makes it easier to understand the various types of collections that exist and to compare them.
What is taxonomy?All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.
For a number of reasons, taxonomy, or the classification of collection kinds, is crucial.
Secondly, taxonomy enables us to classify and organize collections based on their traits, which facilitates comprehension of the numerous sorts of collections that exist and allows for simpler comparison.
To ensure that collections are properly managed, preserved, and available for future generations, taxonomy is an essential tool for understanding the development of collection strategies, technologies, planning, and techniques of collecting.
Thus, it is important to have a taxonomy or classification of types of collection.

Identify the effects of the vagus nerve on the following components of the digestive system Salivary glands Pyloric sphincter (gastric emptying) Smooth muscle in the gallbladder Smooth muscle in the duodenal papilla (sphincter of Oddi)
Answer:
Vagus nerve is the 10th cranial nerve. It is long start from brain and distributed over head, thorax and abdomen.
Explanation:
1. In the salivary gland the secretory and vasodilator effect on afferent nerve is mediated mainly by parasympathetic reflex which is given by vagus nerve.
2. Pyloric sphincter is the part present between the stomach and small intestine which regulate the flow of food particles from stomach to the intestine. Vagus nerve control the activities of pyloric sphincter. Vagus nerve help the pyloric sphincter to relax.
3. Efferent nerves of vagus nerve help the gall bladder to contract. Vagus nerve is stimulating the gastric tract to contract. So the vagus nerve stimulation promotpromotprthe production of CCK hormone and it will lead to the contraction and secretion of hormones from the gallbladder. Those contractions will help the gallbladder to empty the hormones from gallbladder.
4. The efferent nerves of vagus nerves act on the smooth muscles of duodenal papila. As above says it lead to the contraction of smooth muscles and also promote the production of CCK.
Consider a material for a vascular graft application with proteins adsorbed to its surface and a second material with proteins covalently attached to its surface. For which material would you expect the protein layer to be more stable under flow conditions similar to those found in a blood vessel? Why?
Answer is given below :
Explanation:
Individual-specific proteins are placed on the graft material so that the body does not recognize the graft as a foreign substance and treats it as a part of the body’s natural tissue structure. If the body recognizes the graft as a foreign substance, it produces an immune response against it and leads to a graft rejection reaction by the body. In order for these proteins to attach to grafts, a covalent bond for absorption must be preferred. Absorption is a reversible process and, if used, can lead to de-absorption of bound proteins, including blood, after dissolving by turbulence and pulling to the grafting material by blood flow (velocity up to 40 cm/sec). The remaining infectious tissue is detected foreignly, activating the immune response. On the other hand, covalent bonding is irreversible in nature and vascular flow does not have a disruptive effect on the bond between the graft and the protein, reducing the stable state of the graft and the possibility of rejection.Does climate change tend to be more abrupt or gradual?

Based on the data table below, which number would be the BEST choice for the top number of the scale on the vertical axis of a scatter plot showing this data?
Answer:
D. 70
Explanation:
From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.
If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).
Distance would be in the vertical axis, while time would be in the horizontal axis.
Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.
The role of the ___________ branch of the autonomic nervous system mediates control of organ processes when the body is essentially ______.
Answer: parasympathetic; at rest
Explanation: The parasympathetic nervous system branch of the autonomic nervous system is largely responsible for the relaxation of the body especially at rest where it undoes the activities of the sympathetic branch by decreasing respiration, heart rate and then increasing the body's digestion rate. As such, this branch is also responsible for digestion response in a relaxed, resting, or feeding states. The role therefore of the parasympathetic branch of the autonomic nervous system mediates control of organ processes when the body is essentially at rest.
