Summarize the three main reasons why energy is wasted at each trophic level. (use your own words)
Answers
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

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.

A student observed a palisade cell using a microscope. The microscope had four objective lenses, each with a different magnification. Which objective lense should the student use?
Answers
Answer:
x4 objective
Explanation:
The student should use the x4 objective lense in order to be able to observe the palisade cell of a leaf.
The palisade cells are located below the cuticle and the epidermis of the leaf and the x4 objective will provide the largest field of view for adequate study by the student. The x4 objective is also easier to focus compared to the lower objectives.

Answers
Answer:
B. All carbon atoms have six protons and six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons
Explanation:
Isotopes are atoms of the same elements having same atomic number but different atomic masses.
Atomic number is the number of protons (or electron number in neutral atoms) present in the atomic nucleus of the atom.
Atomic mass number is the sum of protons and neutrons present in the nucleus of the atom.
Considering the options above from the above definitions:
A. All carbon atoms have six neutrons is false because carbon-12, carbon-13 and carbon-14 has 6, 7 and 8 neutrons respectively.
B. All carbon atoms have six protons and six electrons is true because the atomic number of carbon is 12.
C. Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons is false because atoms of all carbon isotopes have six electrons.
D. Atoms of some naturally occurring carbon isotopes may have six neutrons is true because atoms of carbon-12 have six neutrons.
E. Atoms of some naturally occurring carbon isotopes may have twelve neutrons is false because none of carbon-12, carbon-13 or carbon-14 have twelve neutrons.

What are celestial bodies?A celestial object is an observable cosmic phenomenon that happens naturally. The terms "object" and "body" are frequently used synonymously in astronomy.
A celestial object, on the other hand, is a complex, less cohesively bonded structure that could include numerous bodies or even other objects with substructures, as opposed to a celestial body, which is a single, tightly bound, adjoining entity. Space objects like the Sun, planets, moons, and stars are referred to as celestial bodies or heavenly groups.
They are normally quite far away from us and are a part of the vast cosmos we inhabit. Such objects are scattered throughout the majestic night sky, and when viewed through a telescope, they reveal intriguing worlds of their own.
Therefore, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.

In studying the environment, nature does the experiments, scientists collect the data. How does the principle of uniformitarianism help answer questions about environmental changes?
Answers
Answer:
The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.
Explanation:
The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.
Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.

Which question can be used to evaluate reliability of a source?
“Do these results support the author's own opinion?”
“Is this data challenged by anyone in the public?”
“Is this research relevant to me?”
“Who was paid to do this research?”
Answers
Answer:
Do these results support the Author's own opinion?
Explanation:
The question can be used to evaluate the reliability of a source is Do these results support the author's own opinion?
In sources (books, articles, etc), reliability implies the information of a source can be trusted. This occurs if:
All the information is based on factsThe information is not manipulated by the author's opinion or interestsIn this context, it is expected the information of the source is objective rather than influenced by the author's opinion. Therefore, one way to check the reliability of a source is "Do these results support the author's own opinion" because if the information is manipulated by a personal opinion, the source is not reliable.
Also, other questions are not appropriate because they are related to other aspects such as relevance, not reliability.
