Answer:

The correct answer is option D, confirmation bias.

The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.

The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.As the two scientists interpret the data (or experimental results) in different ways to adhere to the different hypotheses. this is also called indicative of cognitive bias. This is also called inductive reasoning where the premise is viewed as evidence for the validity of the conclusion.

Answer:

Phenotype

Explanation:

The observable physical characteristics of an organism, as determined by both genetic makeup and environmental influences.

The question is asking about the observable physical characteristics of organisms.

We can eliminate options B and C because they don't make much sense. An organelle is a structure in a cell which conducts cellular functions, and the morphology of an organism is basically the anatomy and physiology of the organism, which isn't quite what we're looking for.

Keeping this in mind, here is some information on prefixes:

geno - relating to genes

pheno - relating to what's observable

The second one sounds a lot like what we're looking for, and just in case, the definition of phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Therefore your answer is: A. phenotypes

The incorrect grouping of elements is Argon, potassium, slicon, strontium.

Periodic table is a systematic arrangement of chemical elements within the coloums and rowns on the basis of their properties.

In all options given elements belongs from the same group except the first one, beacuse in argon, potassium, silicon & strontium all are present in different groups of periodic table. As argon is present in the 18th group, potassium is present in the 1st group, silicon is present in the 14th group and strontium is present in the 2nd group of the periodic table.

Hence, correct option is (A).

Answer:

Sulfur trioxide: SO3.

Explanation:

How I came to this conclusion:

I noticed that the compound consists of non-metals, therefore it must be a covalent compound -

meaning I use prefixes for compounds.

Sulfur is S. Simple enough. Trioxide has the prefix of tri, meaning "3". Therefore there is 3 atoms of oxygen. Combine them and I get SO3.

Don't be confused with sulfite: (SO3)2− and sulfate: (SO4)2−

Answer:

to obtain a full outer shell

Explanation:

The atoms of some elements share electrons because this gives them a full valence shell. ... If atoms can't achieve a full outer shell by transferring electrons, they resort to sharing. In this way, each atom can count the shared electrons as part of its own valence shell. This sharing of electrons is covalent bonding.

Atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

Chemical bonding may be defined as a type of interaction that is significantly accomplished through the association of atoms into molecules, ions, crystals, and other stable species that make up familiar substances.

According to the context of this question, the atoms of some elements typically transfer their electrons to the other elements in order to achieve a fully filled outermost shell.

If they do not have a tendency of transferring, they follow a different mechanism of sharing their electrons. The sharing of electrons gives rise to the formation of covalent bonding.

Therefore, atoms generally exchange or share electrons during bonding because they want to obtain a full outer electron shell. Thus, the correct option for this question is A.

Answer:

m = 3.65 gram

Explanation:

ácido clorhídrico = HCl

M = m/Mr × 1000/mL

0.2 M = m/36.5 gr/mol × 1000/500 mL

0.2 M = m/36.5 gr/mol × 2

m/36.5 gr/mol = 0.2 M/2/L

m/36.5 gr/mol = 0.1 mol

m = 36.5 gr/mol × 0.1 mol

m = 3.65 gram

Explanation:

Please look at others answer I am not 100% sure if this is correct.

The cart starts out in position A with high potential energy, low kinetic energy, and some thermal energy. As the cart progresses into position B, the kinetic energy begins to increase and the potential energy begins to decrease; as the thermal energy increases as thermal energy from the track is transferred to the cart through friction. Once the cart reaches position C, it has high kinetic energy, low potential energy, and some thermal energy. At position D, the cart has high potential energy, low kinetic energy, and some thermal energy. The potential energy throughout is correlated to gravity, the kinetic energy is correlated to momentum, and the thermal energy is correlated to friction. The potential energy is at its maximum during position A, and its minimum at position C; the kinetic energy is at its maximum during position C, and its minimum at position A; the thermal energy is at its maximum during position B, and its minimum at position A

Answer:

Explanation:

I'm not sure what is being asked, not the units of "1.5."  I don't know of potassium "ioxicide."  Was "dioxide" intended?

I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).

The molar mass of K2O, potassium dioxide, is 94.2 g/mole.  1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O.  The definition of Molar is moles/liter.  So take the moles of K2O and divide by the liters, which is 0.150L in this case.

(0.0159 moles K2)/0.150 L  = 0.106 M K2O

Answer:

cracks in the road, hot air balloons, tire bursts

Explanation:

cracks in the road: the road expand on heating

hot air balloons: Because the hot air inside the balloon bag increases in size faster than the container it stretches the bag so that it expands and displaces the colder (heavier) air outside the bag

tire bursts in hot days when filled full of air due to thermal expansion

The total energy required to convert the unknown liquid to gas at the given temperature is 7.215 kJ.

The given parameters;

The total heat required to convert the liquid to gas is calculated as follows;

H = Heat to raise to boiling temp. + Heat to vaporize the liquid + Heat of gas vapor

The heat required to raise the temperature of the liquid to boiling point;

[tex]H_1 = mc\Delta t\\\\H_1 = 19.8 \times 1.58 \times (57.3 - 19.2)\\\\H_1 = 1,191.92 \ J\\\\H_1 = 1.1919 \ kJ[/tex]

The number of moles of the liquid is calculated as;

[tex]moles= \frac{19.8 \ g}{83.21 \ g/mol} = 0.238 \ mol[/tex]

The heat required to vaporize the liquid;

[tex]H_2 = n H_{vap}\\\\H _2 = 0.238 \times 22.5\\\\H_2 = 5.355\ kJ[/tex]
