Answer:
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
Explanation:
The whole digestive tube is approximately eleven meters long, from the mouth to the anus.
The small or thin intestine is the longest organ of the digestive tube. It can reach up to 7 meters long, up to 3 centimeters in diameter, and it characterizes by being folded. These folds are called villi, they project into the intestine light, and they are more concentrated in the first portion of the intestine, the duodene, decreasing to the final region of the organ.
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
The small intestine receives food from the stomach, and through peristaltic movements, it mixes and carries the material to different regions in the organ. The complex polymeric molecules are digested and transformed into simpler substances. The duodene receives secretions from intestinal glands such as bile and pancreatic juices and mixes them with digestive juices of its production. All of these secretions carry huge amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids. The intestine walls are covered by villi that increase the absorption surface area. Nutrients are absorbed by primary cells and transported to the bloodstream. Calciform cells secrete mucus to protect the epithelium during digestion. Villi also transport water from the blood to the intestinal tract, which helps in food decomposition. Enteroendocrine cells secrete hormones to the blood vessels and capillaries that enter each villus. When nutrients are small enough they go to enter the bloodstream.
Peyer's patches are nodules or cumulus of lymphatic tissue and other accessory cells, located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine, in the jejunum region. These patches represent the mucosa´s immunity system. In the jejunum, these follicles are isolated from each other in the intestine and low concentrated. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.

If a plant takes in 6 CO2 molecules and 6 H2O molecules in order to build one C6H12O6 molecule, what element will the plant have "extra" of / What element will be "extra"?
Answer:
Oxygen (O2)
Explanation:
This question is describing photosynthesis which uses carbon dioxide and water as reactants in the presence of sunlight to synthesize sugar (glucose) and oxygen. The general equation is as follows:
6CO2 + 6H2O ---> C6H12O6 + 6O2
According to this question, a plant takes in 6CO2 molecules and 6H2O molecules in order to build one C6H12O6 molecule. Using the balanced equation above, the extra element is OXYGEN, which still needs to be released as a gas for the equation to be balanced i.e 6O2 molecules

"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next."
Through his work, Mendel published his experiments to explain his findings.
What did his laws of inheritance state?
SELECT ALL THAT APPLY
A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.
B.Each trait of an organism can contain multiple alleles of that trait.
C.Organisms with alternate forms of a gene will express the dominant form of the gene.
D.The inheritance of one trait is not dependent on the inheritance of another.
E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.

Describe Piaget’s processes of assimilation and accommodation. Use an example to illustrate the processes.
Answer: For Piaget's process of accommodation it is when you change schema to accommodate new info.
example: Once you learn about something you modify your understanding of a concept to include specific categories. For example, when a child sees a dog, it has four legs and fur. But when they see a cat they create a new schema for cats.
Answer Process of assimilation adds on to pre-existing information/experiences.
example: going back to our cat-dog example. When they develop a concept of a dog as being a four-legged thing with fur, when they see a cat they will place the cat in the same category as a dog and be like "that's a dog" to anything that fits their concept of a dog.

A. Nervous tissue
O B. Epithelial tissue
O C. Connective tissue
O D. Muscle tissue
The type of tissue which produces the movement is known as Muscle Tissue. The correct option is D.
Muscle tissue is made up of cells that have the unique ability to shorten or contract in order to move bodily parts. The tissue is densely cellular and rich in blood capillaries. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically organized in bundles or layers surrounded by connective tissue.
Actin and myosin are muscular proteins found in muscle. Skeletal muscle tissue, smooth muscle tissue, and heart muscle tissue are the three types of muscle tissue.

A line passes through the points( -3,-4) and (6,2)
Answer:
y = ⅔x - 2
Explanation:
We can solve for a linear equation of a line that passes through these two points by the elimination method and then substitute.
We simply write these two points in the form y = mx + c, where m is the gradient and c is the y-intercept (offset). So:
-4 = -3m + c
2 = 6m + c
____________ -
We can first eliminate c to solve for m and then substitute m back into either equation to solve for c. (See attached image for solving steps)
Then, we get:
m = ⅔
c = -2
so y = ⅔x - 2

Is the coloring of the peppered moths an example of competition, differential reproductive success, or inherited variation? Explain why.
Answer:
Peppered moths get their color in lieu to become the fittest among all so that they can survive easily.
Answer/Explanation:
Differential reproductive success.
When the Birch(white) trees were covered in soot(making them black). The black pepper months could blend in to the tree while the white moths stood out.
When the Birch(white) trees were clean and white. The white pepper moths could blend in to the tree while the black moths stood out.
This is an example of differential reproductive success. Who ever could blend in with the tree had the better genes because it made them difficult to be spotted. The other type of moth would be not so lucky, easily spotted an eaten. The better gene lead is "successful," because that moth could live longer because of its characteristics..

If researchers use only the number of coral found in dive 1, calculate the predicted population of brain coral in a reef that covers 120m squared. i forgot how to do this :))
Answer:
40
Explanation:
Each quadrant measured = 2m X 2m
Length = (2+2+2) m = 6m
Width = 2m
Total area = area of (quadrant 1 + quadrant 2 + quadrant 3)
Total area = 6 * 2 = 12 m^2
Number of coral found in dive 1 = 4
Population density = 4/12 = 1/3 (0.33)
Now,
=> Population density = (Predicted population)/area
=> 1/3 = PP/120
=> PP = 120/3 = 40
So, the required answer is 40.
The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40

What could explain the curve in this population growth graph? A graph has time on the horizontal axis and population size on the vertical axis. The population size was constant for a period of time, increased rapidly, and then became constant again. an unlimited food supply a natural disaster a population crash a reduction in predators
Answer:
A reduction in predators
Explanation:
I just took the test
A reduction in predators could explain the curve in this population growth graph.
How does reduction in number of predators lead to curve?The prey species soon degrades and overruns its area since there are no predators to regulate the population and modify feeding behavior.When food becomes scarce, people grow unwell and famished, and they either flee or crash.When predator populations grow, putting more pressure on prey populations and acting as a top-down control, pushing them toward extinction. As a result, the size of prey populations is influenced by both resource availability and predation.
