A learned behavior is a behavior that develops during an animal’s lifetime.
Examples of learned behaviors include tying one’s shoes or solving a math problem.
An inherited behavior is a behavior that an animal is born with.
An example of an inherited behavior is a bird building a nest.
Explanation:
Learned behaviors are those which are gradually developing in us through learning at different ages and it takes time. Inherited behaviour is innate to us which are incorporated with us by birth.
What is learned behaviour?An organism develops a learned behavior as a result of experience. In contrast to learned actions, inherent behaviors are genetically preprogrammed and can be carried out without any prior knowledge or instruction.
Certain behaviors have features that are both acquired and innate. Zebra finches, for instance, have a genetic predisposition to learn a song, but the song they sing is influenced by what they hear from their dads.
Inherited behaviors are inherited from parents to their offsprings. Such as similar nature in sound, angriness, some diseases etc. They are not gathered from any experience and are accompanied by birth.

explain why diamond has a high melting point
Answer:
Each carbon atom is covalently bonded to 4 other carbon atoms in diamond. A large amount of energy is required to split these atoms apart. This is because of the fact that covalent bonds are strong.
In diamond 4 carbon atoms are strongly bonded with covalent bond and they form giant covalent structure which requires large amount of energy to break down, that’s why diamond has a high melting point. It does not conduct electricity.
A student studies photosynthesis and cellular respiration in plants. Which of the following reactions would produce 12 grams (g) of glucose and oxygen?
when a total of 12g of carbon dioxide and water react in photosynthesis
when a total of 24g of carbon dioxide and water react in photosynthesis
when a total of 12g of carbon dioxide and water react in cellular respiration
when a total of 24g of carbon dioxide and water react in cellular respiration
Answer:
The answer is A
Explanation:
Because I used the elimination rule none of the other ones could be an answer.
When a total of 12g of carbon dioxide and water react in photosynthesis would produce 12 grams (g) of glucose and oxygen. Therefore, option (A) is correct.
What is photosynthesis?Photosynthesis can be described as the process that takes place in plants through photosynthetic pigments such as chlorophyll. All green plants have a photosynthesis process to produce glucose by using water, carbon dioxide, and sunlight. The side product of this process in plants is oxygen.
The photosynthesis process is also utilized by algae to change solar energy into chemical energy. Photosynthesis takes place when plants utilize sunlight to change carbon dioxide and water into glucose and oxygen.
The Chemical equation of photosynthesis in plants is:
6CO₂ + 6 H₂O → C₆H₁₂O₆ + 6O₂
For a balanced chemical reaction, the total mass of the reactant is equal to the total mass of the products, so if the 12 g of carbon dioxide and water react with each other then 12 g of glucose and oxygen will be produced.

determine the number of protons neutrons and electrons in 3216s2
Answer:
Number of protons = 16
Number of neutrons = 16
Number of electrons = 18
Explanation:
The atom given is (32,16)S_2.
This simply Sulphur atom.
What (32,16)S_2 implies is that;
Atomic number = 16
Mass number = 32
Now atomic number means number of protons present in the atom
While mass number means number of sum of protons and neutrons present in the atom
Thus;
Number of protons = 16
Number of neutrons = 32 - 16 = 16
Now, for a neutral atom, number of protons is equal to number of electrons.
However, in this case it's not neutral but has a charge of -2.
Thus,
Number of electrons = 16 + 2 = 18 electrons
So weird question kind of, not sure how to phrase this; but in the periodic table, the groups are labeled 1 through 18, however, the most amount of valence electrons an element can have is 8, so why are they labeled 1 through 18? What do those numbers stand for?
The elements are placed in groups and periods on the contemporary periodic table, according to this definition. The elements are organized in the current periodic table in order of increasing atomic number. This periodic table has 7 periods and 18 groupings. Horizontal rows form the arrangement of the periods.
What is a periodic table?Chemistry is the branch of science that examines the characteristics, make-up, and structure of substances (specified as elements and compounds), as well as the changes they go through and the energy released or absorbed. Every substance, whether created through natural processes or through man made means, is made up of one or more of the roughly a hundred types of atoms that have been classified as elements.
According to the question, groups are :
Groups refers to the vertical rows.The periodic table has a total of 18 groupings.The distinction between the groups is made on the basis of valence electron count and degree of reactivity.All elements in the same group of elements have the same chemical behavior for their outermost electrons.To get more information about Periodic Table :

Answer:
Plastics are large organic molecules called polymers.
Explanation:
Plastics can be defined as materials that can be shaped when soft and then hardened to keep their shape. They are synthetic (artificially made) or semi-synthetic, derived from materials found in nature, such as natural gas, oil, coal, minerals, and plants.
As they are derived from natural, organic materials, plastics also consist of organic molecules. Their molecules are very large and long and consist of many repeating subunits. Materials with this type of structure are called polymers.

How are masses and volumes of the objects related to their densities?
Answer:
please mark me brainliest :D
Explanation:
Knowing the mass and volume of an object allows the calculation of its density. Density is defined as the mass divided by the volume of the object. The general physical law relating to floating objects is known as Archimedes' Principle.
The three most fundamental characteristics of an object are mass, volume, and density. Volume indicates something's size, mass indicates how heavy it is, and density is calculated as mass divided by volume.
Mass divided by volume is how density is calculated. It is clear that the relationship between density and volume is inverse. This implies that the density will decrease if the mass of a body remains constant while its volume rises. In contrast, if the volume decreases, density will rise while the mass stays the same.
If the mass or volume of an object is altered, the density of the thing may also change. Water, for example, has a specific density.

A student collects the following data to determine the density of a metal cube. What is the correct density ( including absolute uncertainty)? Pls Help me with this questions!!!!!!
Mass of metal Length of Metal Height of Metal Width of Metal
4.56 +/- 0.05g 1.54 +/- 0.05cm. 6.24 +/- 0.05cm. 1.00 +/- 0.05cm
The density of the metal including absolute uncertainty is ρ = 0.48 g/cm³ ± 0.03 g/cm³
How to find the correct density of the material?The density of the material is the mass/volume
Since the metal has
mass m = 4.56 ± 0.05g, length, l = 1.54 ± 0.05cm, height, h = 6.24 ± 0.05cm and width, w = 1.00 ± 0.05cmIts density = m/v where
m = mass and v = volume = lwhρ = m/lwh
ρ = 4.56 g/(1.54 cm × 6.24 cm × 1.00 cm)
ρ = 4.56 g/9.6096 cm³
ρ = 0.475 g/cm³
ρ = 0.48 g/cm³
To find the absolute uncertainty in density, we first find the relative uncertainty which is given by
Δρ/ρ = √[(Δm/m)² + (Δl/l)² + (Δh/h)² + (Δw/w)²] where
Δm = ± 0.05 gm = 4.56 gΔl = ± 0.05 cml = 1.54 mΔh = ± 0.05 cmh = 6.24 cmΔw = ± 0.05 cmw = 1.00 cmSubstituting the values of the variables into the equation, we have
Δρ/ρ = √[(Δm/m)² + (Δl/l)² + (Δh/h)² + (Δw/w)²]
Δρ/ρ = √[(0.05 g/4.56 g)² + (0.05 cm/1.54 cm)² + (0.05 cm/6.24 cm)² + (0.05 cm/1.00 cm)²]
Δρ/ρ = √[(0.010965)² + (0.032468)² + (0.008013)² + (0.05)²]
Δρ/ρ = √[0.00012023 + 0.00105417 + 0.00006421 + 0.0025]
Δρ/ρ = √0.00373861
Δρ/ρ = ± 0.061
Δρ/ρ ≅ ±0.06
So, the absolute uncertainty in density, Δρ = Δρ/ρ × ρ
= ±0.06 × 0.48 g/cm³
= ± 0.029 g/cm³
≅ ± 0.03 g/cm³
So, the density of the metal including absolute uncertainty is ρ = 0.48 g/cm³ ± 0.03 g/cm³

The influence of various wet chemical treatments on the germanium wafer surface has been examined. The GeO2 part of the native oxide is readily dissolved in water. The solubility of the GeO2 in aqueous solutions and the fast oxidation of germanium makes commonly used silicon treatments nonapplicable due to the relatively high etch rates. In various etching chemistries, the underlying suboxide is not attacked. A hydroxylated suboxide might be an ideal starting surface for ALD, because of its low contribution to electrical thickness. HBr removes even the suboxide and yields a completely oxide-free germanium surface which makes it a candidate surface preparation technique for epitaxial growth. The same result is obtained using a HI dip followed by a DIW rinse. Oxide is growing in CR-air, while in N 2 ambient the surface remains stable.
An oxide is a category of chemical compound that has one or more oxygen atoms as well as another element in its composition such as Li2O, CO2, H2O, etc.
