Answer:
1. 6.7%
hope it helps <3
The percentage deviation in the student's calculation is 6.74%.
We have a student who incorrectly measured the volume of a mineral sample.
We have to determine student's approximate percent deviation.
How to calculate the Percentage deviation ?In order to calculate percent deviation , subtract the true value from the measured value, then divide by the true value, then multiply by 100.
According to the question -
Measured volume (M) = 83 cubic centimeters.
Actual Volume (A) = 89 cubic centimeters.
ΔV or [tex]$\delta[/tex]V = M - A = 83 - 89 = - 6
Therefore -
|Percentage deviation| = [tex]\frac{\delta V}{A} \times 100[/tex] = - ( [tex]\frac{6}{89} \times 100[/tex]) = - 6.74 % = 6.74%
Hence, the percentage deviation in the student's calculation is 6.74%.

Explanation:
are forest fires biotic or abiotic
Answer:
biotic
Explanation:
because bio means life then forest fires must be biotic
Fire is non-living, and non-living elements are the abiotic elements in an ecosystem. Thus, fire is an abiotic element in an ecosystem, but rarely mentioned.
The forest ecosystem is made up not only of living organisms (trees, animals, plants, and other living things) but also of non-living organisms (soil, water, air, and landforms) that make up the forest ecosystem.
A forest ecosystem’s abiotic elements include oxygen-rich air, water present in several bodies of water, organic compounds in the trees and soil, and dead plant and animal remains.

question:
The unit of genetic organization in all living organisms is the chromosome.
How does the function and structure of the chromosome differ in prokaryotes?
Answer:
The structure and function of the chromosome are different in both the prokaryotic chromosome and eukaryotic chromosome. They differ in their size as the genetic information they carry is different from one another.
Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.

inject DNA or RNA into the nucleus of a cell to reproduce.
Answer:
The characteristic of injecting DNA or RNA into the nucleus of a (host) cell corresponds to viruses.
Explanation:
Viruses are not considered living beings, since they are only made up of genetic material covered by a viral capsid and cannot fulfill the functions of a cell. For this reason viruses need to introduce their genetic material into a host cell, to transcribe its genetic code and achieve replication.
Due to their mechanism of reproduction, viruses are biological agents capable of producing disease by altering the conditions of the organisms they use as hosts.

Force and velocity are different because
Answer:
A force pushes or pulls on an object, but velocity is simply something an object has.
Explanation:
Force and velocity are different because force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.
What is a Force?A force may be defined as a process of pushing or pulling on an object with mass that significantly causes it to alter its velocity. It is a vector quantity that has both magnitude and direction.
Velocity is characterized as the distance covered by an object in a unit of time. In a more simple sense, it is also defined as the displacement of the object in unit time. It is a vector measurement of the rate and direction of motion.
Therefore, force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.

Which of the following inhibits the seepage of rainwater into ground
(a) Concrete floor (b) play ground (c) grass lawn (d) forest land
Answer:
What inhibits rainwater seepage into the ground is the concrete floor.
Explanation:
In general, water from rain is usually absorbed by the ground, due to its relative porosity. Concrete is solid and non-porous, forming an impermeable layer that prevents water from passing through it.
Concrete comes from a mixture of cement, sand and water, forming a malleable mass that hardens when dry. It is used for the manufacture of floors and buildings, and is characterized by its relative impermeability.
Other options are not correct because:
Playground, grass lawn and forest land allow the absorption of water from rain.
Answer:

A.The number of protons and neutrons
B.The number of protons
C.The number of electrons
D.The number of balance electrons
Answer:
answer is A
Explanation:

The information would be most helpful in determining the atom's identity is The number of protons and neutrons .
What is atom?The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.
Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.
Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus.
The protons are positively charged, while the electrons are negatively charged.
Therefore, The information would be most helpful in determining the atom's identity is The number of protons and neutrons .
