Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.
B-are made out of organic material that stores the sun energy
C-form where there are frequent earthquakes and volcanic activity
D- are produced high in the mountains where temperatures are low
Answer:
maybe C i'm so sorry if this is wrong
Explanation:
Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.
What are fossil fuels?An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.
Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

which bone layer holds calcium and other minerals
Answer:
In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

b
(negative 3 + 8) divided by 2
c
(negative 3 + 8) divided by (negative 2)
d
Negative (3 + 8) divided by 2
Answer:
B
Explanation:
The negative goes by the 3 because it is 3 degrees below zero. To find averages, you add the numbers and divide by how many numbers there are. in this case, it would be (-3+8)/2

The chart shows information about three different embryos early in their development.
Which is best supported by the information in the chart?
Species X and Y are not related to humans.
Species Y and Z are not related to humans.
Species X and Z are related to humans.
Species X and Y are related to humans.
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

Answer: I believe the answer you're looking for is Adenine goes with Thymine and Cystosine goes with Guanine.
Hope this helps!!
The four DNA strands that match the strand in the diagram by base pairing is GGTGACT. The correct option is A.
What is base pairing?A base pair, which consists of two nucleobases joined by hydrogen bonds, is the basic building block of double-stranded nucleic acids.
They contribute to the folded shape of both DNA and RNA and serve as the building blocks of the DNA double helix.
base pair of DNA. The nitrogen-containing bases adenine (A), thymine (T), and cytosine (C), as well as guanine (G), couple together under normal conditions.
