MACROMOLECULES:
Macromolecules are large or complex molecules made up of monomers. The macromolecules in nature are as follows: proteins, carbohydrates, lipids and nucleic acids. Each macromolecule performs specific functions in the body and hence, are very important. Carbohydrates and lipids are used as energy storage, however, lipids store energy in the body for a long term than carbohydrates. Carbohydrates store energy for a short term because they are readily used by the body.Therefore, both macromolecules are used for energy storage, but only carbohydrates are used for short-term energy storage.

It is believed the major reason for the decline in amphibian species is _______.
a.
death through disease
b.
changing reproductive habits
c.
mutation
d.
climate change
Answer: It is believed the major reason for the decline in amphibian species is death through disease.
Explanation:
The major reason for the decline in amphibian species is climate change.
Amphibians are organisms that can live on land and in water. They are
usually found around moist areas because they need water bodies to cool
off in order for their survival.
Climate change is characterized by an increase in temperature which
doesn't favor them as they lose more water which thereby threatens survival
and leads to their decline in the ecosystem.

Q1.What is the mass of 5 moles Of 1.Mg 2.CaCO3 Q2. Calculate the number of atoms in 10g of Na Q3.calculate the number of molecules in 10g of NaCl Q.4.What is Avogadro's number? How many number of atoms are present in 4g of Oxygen?
Answer:
Explanation:
Q1) as we know that moles=given mass/molar mass
mass of 5 moles of Mg is
mass =moles*molar mass
mass=5*24
mass=120 g
mass of 5 moles of CaCO3 is
mass= moles*molar mass
mass=5*100=500
Q2) number of atoms in 10 g Na
first we need number of moles of sodium
moles =mass/molar mass
moles=10/23=0.43
now we know that moles=number of atoms /avogadro number
for number of atom the formula become
number of atom=moles*avogadro number
number of atom=0.43*6.023*10^23=2.6*10^23
Q3)number of molecule in 10 g of NaCl
again we need number of moles of NaCl
moles=given mass/molar mass
moles=10/58.5=0.17
now number of molecules=moles*avogadro number
number of molecules=0.17*6.023*10^23=1.02*10^23
Q4) avogadro number is the number of particles(atoms,molecules,ions) present in one mole of a substance its value is 6.023*10^23
Q5)Number of atoms in 4g of oxygen
again we need number of moles of oxygen
moles=mass/molar mass
moles=4/16=0.25
now number of atoms=moles*avogadro number
number of atoms=0.25*6.023*10^23 =1.5*10^23
Which property refers to how a mineral reflects light?
Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.
Answer:

How do protons, neutrons, and electrons differ in terms of their electrical charges and
locations within the atom?
Answer:
Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus
Explanation:
Protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus.
Explanation:
Atom is defined as the smallest unit of a matter.It consists of three subatomic particles: protons, neutrons, electrons.Protons and neutrons are located inside the nucleus. They are also known as nucleonsElectrons are located outside the nucleus.Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge (neutral).So from this, we conclude that the protons are positively charged, neutrons are neutral and they both are located in the nucleus whereas electrons are negatively charged and located outside the nucleus

What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:
the answer is [Rn]7s25f14 (first option)
Explanation:
i took the test
The electronic configuration for nobelium (No) is [Rn]7s²5f¹⁴, hence the correct option is A.
What is electronic configuration?The distribution of an element's atoms' electrons throughout several atomic orbitals is symbolically represented by the electronic configuration of that element.
A standardized nomenclature is used for expressing electron configurations, in which the energy level and type of orbital are written first, followed by the number of electrons in the orbital, which is expressed in superscript.
The atomic number of nobelium (No) is 102.
The number of protons is equal to the atomic number, which is 102.
The number of electrons is equal to the number of protons, which is 102.
Therefore, electronic configuration for nobelium (No) is [Rn]7s²5f¹⁴.

water.
Which best describes oil and water?
Oil and water are highly soluble because they have
separate chemical properties.
Oil and water have a low solubility because they
have separate chemical properties.
Oil and water are highly soluble because they exert
different pressures
Oil and water have a low solubility because they
exert different pressures.
The answer is option B :)
According to the concept of solubility, oil and water have a low solubility because they have separate chemical properties.
What is solubility?
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
