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.

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.

Why is the nitrogen cycle important for the survival of organisms in an ecosystem? A. The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms. B. The nitrogen cycle keeps organisms from consuming nitrogen in their ecosystem. C. The nitrogen cycle allows all organisms in an ecosystem to consume nitrogen instead of consuming each other. D. The nitrogen cycle stores nitrogen in safe places, keeping it from entering an ecosystem.
Answer: A.) The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms.
Explanation: Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use.
2. What are the two types of ecological succession?
Answer:
There are two main types of succession, primary and secondary. Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.
Explanation:
Answer:
Ecological succession is a process of change in ecosystems that takes place over time, and that we can observe both in time and in space. ... There are two types, the primary sequence and the secondary sequence.

A scientist is observing an organism under the microscope. The organism was found in salt water, is multicellular, and its cells do not have nuclei. What is most likely true about the organism based on this information?
Answer:
I think the options should be:
It is a protist because it is microscopic.
It is not a protist because its cells do not have nuclei.
It is not a protist because it is multicellular.
It is a protist because it is found in salt water.
If correct, then the answer is option B
Explanation:
The above information about the organism can confirm that the organism is not a protist because it does not possess nuclei. It could be a prokaryote but these are not multicellular but can only be under the condition that maybe each prokaryotic cell aggregates and exist as a colony.
Answer:
the answer is its a protis bc its microscopic .

The high temperature on Friday was 8 degrees above zero. The low temperature was 3 degrees below zero. Which expression gives the average of the low and high temperatures?
a
Left-bracket negative 3 + (negative 8) right-bracket divided by (2) Right-bracket
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

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.

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.
Why did the deer start to avoid certain areas of the park, like valleys and gorges?
