What if researchers followed a similar method used in this activity to calculate the correlation coefficients for the gene expression patterns of every patient with osteosarcoma and they found that all patients fell into two categories of gene expression patterns? What would this tell you about the single disease we call osteosarcoma? How might this information affect osteosarcoma cancer patient diagnosis and treatment in the future?

Answers

Answer:

- Abnormal gene expression patterns can lead to osteosarcoma

- Different signaling pathways (at least two) are involved in osteosarcoma

- Differentially expressed genes might be promising biomarkers for early detection of osteosarcoma

Explanation:

Cancer can be defined as a group of genetic diseases that are characterized by uncontrolled/inappropriate cell growth. In general, cancer pathways are associated with abnormal expression of signaling components that disrupt the regulatory networks capable of controlling cell function, thereby cancerous cells can inhibit programmed death cell (apoptosis). Osteosarcoma is one type of cancer disease that starts in the bones, i.e., this disease may be triggered by overactivity of bone cells. Additionally, it is important to note that different immune-related genes were recently found to be dysregulated in osteosarcoma. For example, differentially expressed immune-related genes involved in PI3K/AKT, MAPK and JAK-STAT signaling pathways have shown prognostic value in this disease.

Abnormal gene expression patterns can lead to osteosarcoma, different signalling pathways are involved in osteosarcoma, and differentially expressed genes might be promising biomarkers for the early detection of osteosarcoma.

What is the cause of osteosarcoma?

Most osteosarcomas are not caused by inherited gene modifications, but instead are the effect of gene changes acquired during the individual lifetime.

Sometimes these gene modifications are caused by radiation therapy used to treat another form of cancer because radiation can harm the DNA inside cells.

Thus, these are the following reasons.

Can someone explain to me the process of deposition? Does it form rocks or does it just transport them. Please help thanks

Answers

Answer:

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

A line passes through the points( -3,-4) and (6,2)

Answers

What are you asking? Slope? If so. You would do change in y over change in x. So subtract 2 and -4 to get positive 6, then subtract 6 and -3 to get positive 9. Your slope is either 1/3 if it’s increasing, or negative 1/3 if it’s decreasing.

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

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.

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"?

Answers

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

Describe Piaget’s processes of assimilation and accommodation. Use an example to illustrate the processes.

Answers

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.

"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.

A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.

Answers

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.
