What are the major sources of evidence for evolution how does each support the theory of evolution?
Answer:
DNA is one of the major sources might be wrong tho
Explanation:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Which of the following is TRUE about sedimentary rock?
A. does not contain layers
B. May contain fossils
C. the hardest of the rock types
Answer:
B
Explanation:
Sedimentary rock is layered. That makes A wrong, but it leads to another observation.
Things can die and think sink to the bottom of an ocean or sea or river or lake bed which over time changes. So you might find fossils which is the answer.
C is incorrect because there are much harder substances than sedimentary rock.
Answer:
B.May contain fossil.
Explanation:
These rocks are formed with the deposition of materials broken down from pre-existing rocks, followed by compaction and cementation

what is called bio pesticides ?
Answer:
hope it helps uh ❤❤ and plzz mark me as brainlist❤❤A specific location in America has closed down several fossil fuel units and set up geothermal plants. In your own words, explain how this would affect the economy of the location. (5 points)
Answer:
The economy of the location would be affected in the following ways:
1. Setting up geothermal plants would create more Jobs as expertise in various fields would be required to render their services.
2. Setting up geothermal plants would increase more revenue generation for the government in taxes.
3. Setting up geothermal plants would attract the development of the location as more people would tend to live there, there would also be improved road networks, housing, e.t.c.
4. Closing down fossil fuel units would eradicate environmental pollution in terms of oil spillage and stop the reduction that has been ravaging agricultural activities due to contamination of water bodies and land as a result of the fossil fuel.
Explanation:
Geothermal power plants are expensive but renewable sources of electricity that use steam or hot water pumped to the Earth's surface from beneath the earth's crust to spin a turbine producing electricity.

Which two viral characteristics provide evidence to support the
argument that viruses are more similar to living components than to
nonliving components of an ecosystem?
Living Characteristics of Viruses Nonliving Characteristics of Viruses They reproduce at a fantastic rate but only in living host cells. They can mutate. They are acellular that is they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.

why does the oceanic crust continuously subduct
Answer:
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust. As the oceanic crust is naturally denser, this melting leads to heat being transferred upwards and uplifting the crust, eventually developing into a volcano.
Drought, erosion, flood, and long heat spells are examples of - O populations O abiotic changes within an ecosystem which can affect biotic factors. biotic factors within an ecosystem which affect abiotic components. o communities
Answer:
The answer is Abiotic
Explanation:
Abiotic are non living things

Which type of transport requires the added energy of ATP?
A. active
B. passive
Answer: A. active
Explanation:
Answer:
(A)Active Transport
Explanation:
Active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

# ⎆ BUTTER is melting!!!! ❦PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.
Answer:
Autotroph
Explanation:
An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.
According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

Which of the following best explains why animals that inhabit warmer regions tend to have smaller body sizes?
A higher surface-area-to-volume ratio facilitates heat loss.
Animals in warmer climates need to move more quickly to catch prey.
More species inhabit warm climates, and smaller size enables a greater number to live in the same ecosystem.
Smaller body size enables faster reproduction and repopulation to maintain a niche in overpopulated warmer climates.
Answer:
I believe it may be a higher surface area to volume ratio facilitates heat loss
Explanation:
Out of the options it makes the most sense being that larger animals keep heat in...
