option D is correct answer of this questionbecause the rainforest environment is different than the desert environment hope it will help
The reason of why rainforest plants adapted to be a different shape as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.
Adaption of the rainforest plants to the different shapes and size?
It can be like:
Drip tips - where plants contains leaves with pointy tips.Buttress roots - These contain large roots that have ridges that develop a large surface area. Epiphytes - It lives on the branches of trees high up in the canopy.hence, The reason of why rainforest plants adapted to be a different shape as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.

PLEASE HELP Name and define the subatomic particles that are part of an atom. How do they differ from each other? How do these differences contribute to the properties of atoms and molecules?
Answers
Answer:
Explanation:
The nucleus is made of protons and neutrons. The protons define element and have a positive charge. Neutrons have no charge. Atoms also have a cloud of electrons surrounding the nucleus. Electrons are negatively charged. The transferring/removal of electrons determines the charge.
The atom consists of 3 subatomic particles:
Protons: They are positively charged particles present in the nucleus of an atom.Electrons: They are negatively charged particles present in the orbits around the nucleus of an atom.Neutrons: They are neutral particles present in the nucleus of an atom.An atom can be defined by its properties:
Atomic number: It is equal to the number of protons present in a neutral atom.Mass number: It is equal to the sum of number of protons and number of neutrons.Charge: If an atom does not lose or gain any electron, it is a neutral atom. If it loses electrons, it attains a positive charge and if it gains electrons, it attains a negative charge.Thus, we can conclude that protons define the atomic number, neutrons define mass number and electrons define charge on an atom.

0.450 gram of Fe contains how many atoms?
Answers
Answer:
0.450 grams of Fe contains 4.85*10²¹ atoms
Explanation:
Molar mass is the mass of one mole of a substance, which can be an element or a compound.
In this case, the molar mass of iron Fe is 55.85 g / mole. Then you can apply the following rule of three: if by definition of molar mass 1 mole of Fe contains 55.85 grams, then how many moles will contain 0.450 grams?
[tex]amount of moles of Fe=\frac{0.450 grams*1 mole}{55.85 grams}[/tex]
amount of moles of Fe=8.06*10⁻³ moles
On the other hand, Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if by definition of Avogadro's Number 1 mole of Fe contains 6.023*10²³ atoms, 8.06*10⁻³ moles how many atoms does it contain?
[tex]amount of atoms=\frac{8.06*10^{-3}moles*6.023*10^{23}atoms }{1 mole}[/tex]
amount of atoms= 4.85*10²¹ atoms
0.450 grams of Fe contains 4.85*10²¹ atoms

Which ionic compound would you predict to have a higher boiling point: NaBr or
Na2S
Why did you select this compound?
Answers
Answer:
The boiling point of NaBr is higher than that of Na2S
Explanation:
Bromine has higher electronegativity as compared to the sulphur. The ionic strength of the bond formed with Sodium is higher in the NaBr compound. The higher the ionic bond strength the higher will be the boiling point
Also the size of bromine is large as compared to that of sulphur. Large molecules consists of more electron and hence they create der Waals attractive forces due to which the boiling point of compound increases.
Hence, the boiling point of NaBr is higher than that of Na2S

Answers
Answer: 43.8 Volts
Explanation:
Ohms law states that current is directly proportional to voltage applied.
[tex]V=I\times R[/tex]
where V = voltage = ?
I = current = 0.73 A
R = resistance = 60 ohm
Putting in the values we get:
[tex]V=0.73A\times 60ohm=43.8V[/tex]
Thus the voltage of the battery is 43.8 Volts
