Eubacteria: Single-celled bacterial organisms.
Archaebacteria: Single celled bacterial organisms that live in extreme enviroments
Protista : Single-celled organisms more complex than bacteria
Plantae: Multi-celled, complex organisms that produce their own food
Fungi: Multi-celled organisms that don't produce their own food
Animalia: Complex, multi-celled, organisms that consume other organisms for food.
Which is one way that a short-term environmental change will most likely affect organisms within an ecosystem?
O It will lead to larger populations.
O It will lead to speciation.
O It will lead to adaptation.
O It will lead to forced migration.
Answer:
It will lead to forced migration.
Explanation:
Changes in ecosystems affect living organisms. An ecosystem is a self supporting unit in which there is an exchange of materials and energy between the living and non living parts. The living part of an ecosystem is called its biotic component. This includes the organisms that live within the ecosystem. The nonliving parts of the ecosystem such as topography, rainfall etc are called abiotic components of the ecosystem.
A short-term environmental change usually forces organism to leave an ecosystem in their quest for survival. For instance, when short term environmental changes such as a sudden drop in rainfall causes drought, organisms migrate in order to obtain food and water. This is a forced migration.
Answer:
It will lead to forced migration.

An experimental procedure says to accurately weigh approximately 1 g of
substance on analytical balance. Which of the following measurements are
consistent with these instructions? Select all that apply.
1.0456 g
1.0 g
0.9811g
1 g
1.01g
O 0.99
Answer:
1.0456 g and 0.9811g
Explanation:
The measurements that are consistent with the approximate 1 g instruction would be 1.0456 g and 0.9811g.
Analytical balance generally weighs to an accuracy of 4 decimal places. Hence, every other option that is short of being in 4 decimal places is incorrect.
Also, 1.0456 g and 0.9811g when approximated to the nearest whole number give 1 g.
What volume of hydrogen will be produced at STP by the reaction of 67.3 g of tin with excess water according to the following reaction?
Answer:
Sn + 2H2O ==> Sn(OH)2 + 2H2
67.3 g Sn x 1 mol/119 g x 2 mol H2/mol Sn x 22.4 L/mole = answer in liters
Explanation:
Sn + 2H2O ==> Sn(OH)2 + 2H2
67.3 g Sn x 1 mol/119 g x 2 mol H2/mol Sn x 22.4 L/mole = answer in liters
The volume of hydrogen that will be produced from the reaction of 67.3 g of tin with excess water is 12.68 L
How to determine the mole of tin Mass of Sn = 67.3 gMolar mass of Sn = 119 g/mol Mole of Sn =?Mole = mass / molar mass
Mole of Sn = 67.3 / 119
Mole of Sn = 0.566 mole
How to determine the volume of H₂ producedSn + 2H₂O —> Sn(OH)₂ + H₂
From the balanced equation above,
1 mole of Sn reacted to produce 1 mole of H₂.
Therefore,
0.566 mole of Sn will also react to produce 0.566 mole of H₂
Recall
1 mole of H₂ = 22.4 L at STP
Therefore,
0.566 mole of H₂ = 0.566 × 22.4
0.566 mole of H₂ = 12.68 L
Thus, 12.68 L of H₂ were obtained from the reaction.

In the reaction Fe2O3 + 3CO a 2Fe + 3CO2, 10 moles of solid iron and 15 moles of carbon dioxide are produced from 5 moles of iron (|||) oxide and 15 moles of carbon monoxide (CO). What is the ratio of carbon monoxide to solid iron
Answer:
Ratio is 3:2
3CO = 2Fe or 1.5 CO = 1 Fe
Explanation:
Fe2O3 + 3CO = 2Fe + 3CO2
Fe2O3 = Iron (|||) oxide
CO = Carbon monoxide
Fe = Solid Iron
CO2 = Carbon dioxide
Excellent is already balanced.
10 Moles Fe and 15 Moles of CO2
5 Moles Fe2O3 + 15 Moles 3CO = 10 Moles Fe + 15 Moles 3CO2
What is the ratio of carbon monoxide to solid iron
Ratio is 3:2 or 1.5 CO = 1 Fe
What might happen to global atmospheric carbon levels if the polar ice caps were to melt?
If the polar ice caps were to melt then it could lift the lid of a new carbon sink capable of soaking up carbon dioxide.
What happens if the polar ice caps melt?
If all the ice protecting Antarctica, Greenland, and mountain glaciers around the sector were to melt, sea degrees might upward push about 70 meters (230 ft). the sea might cowl all of the coastal towns. And the land place would decrease considerably. but many cities, inclusive of Denver, might live to tell the tale.
How do melting ice caps affect the ecosystem?
Melting ice reasons more warming.
because they are darker in the shade, the ocean and land take in more incoming solar radiation and then launch the warmth to the environment. This reasons more global warming. in this way, melting ice causes more warming and so extra ice melts.

hi:) how to do 2(bi)?
Answer:
4 protons, 5 neutrons, 2 electrons
Explanation:
If you look at the numbers beside Be²⁺, the number 9 is the relative atomic mass and the number 4 is the proton (atomic) number. The relative atomic mass is the sum of the number of protons and the number of neutrons.
Number of protons= proton number.
Hence, number of protons= 4
Number of protons + neutrons= 9
4 + number of neutrons= 9
number of neutrons
= 9 -4
= 5
In an atom, the number of protons and electrons are the same since atoms are electrically neutral. But in an ion, the number of electrons is not equal to the number of protons since the atom gains/ loses electrons to form an ion. A positive sign means that electrons are given away.
Thus, Be gives away 2 electrons to form Be²⁺.
Original number of electrons= 4
Number of electrons in Be²⁺
= 4 -2
= 2
In summary, the number of protons and neutrons in an ion is the same as that of the atom. However, the number of electrons is not the same.

B)C4H1102
C)C6H12O2
D)C6H90
Answer:
Tue answer is B - C4H1102
The chemical formula for the molecule modeled is C₆H₁₂O₂. Therefore, option C is correct.
What is a chemical formula ?The term chemical formula is defined as the elements that form the compound and the numbers of atoms of each element in the smallest unit of that compound. Water is consist of hydrogen and oxygen in a 2:1 ratio. The chemical formula for water is H₂O.
There are 3 main types of chemical formulas that are empirical formula, molecular formula and structural formula.
Empirical formulas represent the simplest whole-number ratio of atoms in a compound, molecular formulas represent the number of each type of atom in a molecule, and structural formulas represent how the atoms in a molecule are bonded to each other.
In a given molecule modeled C₆H₁₂O₂ we see that, there are six atoms of carbon, 12 atoms of hydrogen and 2 atoms of oxygen.
Thus, option C is correct.

Answer:
Conduction only happens when the object is a solid, because conduction happens in objects that are closely, with molecules that are closely packed together, and have a definite shape. Since, in liquids and gases, the shape is not definite nor do they have closely packed molecules., conduction does not take place in them

One million argon atoms is how many mol of argon atoms? (2 significant figures)
Answer:
1.66 * 10^-18 mol of Argon
Explanation:
Avogadro says 1 mol of anything has 6.022* 10^23 atoms/particles. Thus using this principle, 1 million argon atoms will have
[tex]1,000,000 atoms Argon * \frac{1mol Argon}{6.022*10^{23} atoms }[/tex]
[tex]1.66*10^{-18} mol \\\\ of Argon[/tex]
One million argon atoms is equivalent to 1.7 × 10⁻¹⁸ moles of argon atoms.
To convert one million (10⁶) argon atoms to moles of argon atoms, we will use Avogadro's number: there are 6.02 × 10²³ argon atoms in 1 mole of argon atoms.
[tex]10^{6} atom \times \frac{1 mol}{6.02 \times 10^{23}atom } = 1.7 \times 10^{-18} mol[/tex]
One million argon atoms is equivalent to 1.7 × 10⁻¹⁸ moles of argon atoms.
