2. Makes accurate predictions based on only a small amount of empirical evidence

Explanation:

For a phrase or scientific finding to be considered a law, there has to be clear evidence and facts to support that specific finding. In the case of the evolution theory, the evidence is not clear enough to make it a law

Answer:

2. Makes accurate predictions based on only a small amount of empirical evidence

Explanation:

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{7.18 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 11.92691...[/tex]

We have the final answer as

Answer:

Species A and C are related to humans.

Explanation:

got it right on edge.

Answer:A. Species And C are related to humans

Explanation: In the embryo humans and other Species have gill slits, and a tail. Vestigesof tales grew and non-human ancestors. On rare occasions, aremnant of the tail through and embryological development, although this tale of course has no function. An embryos splits are found in the boreals of all vertebrates because they share a common ancestors with fish and which structures first

Answer:

E = 19.89×10⁻¹⁶ J

λ = 1×10⁻¹ nm

Explanation:

Given data:

Frequency of xray = 3×10¹⁸ Hz

Wavelength of xray = ?

Energy of xray = ?

Solution:

speed of wave = wavelength × frequency

speed = 3×10⁸ m/s

3×10⁸ m/s  = λ ×3×10¹⁸ s⁻¹

λ = 3×10⁸ m/s  / 3×10¹⁸ s⁻¹

λ = 1×10⁻¹⁰m

m to nm:

λ = 1×10⁻¹⁰m×10⁹

λ = 1×10⁻¹ nm

Energy of x-ray:

E = h.f

h = plancks constant = 6.63×10⁻³⁴ Js

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10¹⁸ s⁻ ¹

E = 19.89×10⁻¹⁶ J

Answer:

The recessive allele tends to be masked when it's in the presence of the dominant allele.

Explanation:

Many of our traits are affected by our genes. From each of our parents, we receive one copy of every gene. These copies are called alleles.

There are different types of relationships that can occur between alleles. One of them is called dominance. This occurs when one allele masks the other, not allowing its effect to be expressed. The allele that masks the other is called the dominant allele (A), and the masked one is called the recessive allele (a). This means that an individual needs to have only one dominant allele in order for its effect to be expressed (AA or Aa). The effect of the recessive allele will be expressed only when an individual has both recessive alleles (aa).

Explanation:

Titanium is an element found in the d-block group on the periodic table. It is a transition element.

To write the electronic configuration of an element, we must know the number of electrons in them;

 In a titanium atom, we have 22 electrons;

Answer: [Ar]4s^2 3d^2

Explanation:

Answer:

Error or mistakes during DNA replication is accountable for two-thirds or 66% of the cancer cases. These random and unpredictable errors called mutations that occur during the division of a cell as an error in copying of DNA.

DNA replication has three main steps:

Opening and separation of DNA strands of a helix - carried by an enzyme known as helicase that breaks the hydrogen bonds between nitrogenous bases of the helix of DNA.

The priming of the template strand - DNA primase helps RNA primers to bind to both strands at 3' end as soon as it separated

strat assembling the segments of new DNA on strands called elongation of the strands with help DNA polymerase I and after forming new strands the termination of the replication.

Errors or mistakes can occasionally take place if DNA polymerase inserts a wrong base during elongation of the strands.

Answer:

trigonal pyramidal

Explanation:

In NF3, the nitrogen atom is sp3 hybridized. Now we must remember that according to the VSEPR theory, the number of electron pairs in the valence shell of the central atom in a molecule determines its shape.

Here, the nitrogen atom is the central atom and its outermost shell is surrounded by four electron pairs - one lone pair and three bond pairs. This means that it has a tetrahedral electron pair geometry.

However, due to the lone pair, the three fluorine atoms are arranged in a  trigonal pyramidal geometry. Hence the correct shape of the molecule is trigonal pyramidal.

I think it would be 9 moles.

Answer:

A. krypton

Explanation:

give me brainly

Answer:

A. Oxygen

Explanation:

A is the only one that makes sense because plants take in carbon dioxide, use glucose for food, and use energy to photosynthesize, and the only answer they don't use is A (oxygen) because they only produce it but not use it

Answer:

It isnt changing

Explanation:

It stays basically the same becuase it is considered a constant

Answer:

V₂ =  1.92 L

Explanation:

Given data:

Initial volume = 0.500 L

Initial pressure =2911 mmHg (2911/760 = 3.83 atm)

Initial temperature = 0 °C (0 +273 = 273 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

by putting values,

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 3.83 atm × 0.500 L × 273 K / 273 K × 1 atm

V₂ = 522.795 atm .L. K / 273 K.atm

V₂ =  1.92 L

Answer:

Explanation:

Speed of light = Wavelength x Frequency.

605 nm x Frequency = 3x10^8 m/s

6.05 x 10^-7 m x Frequency = 3x10^8 m/s

Frequency = 4.96 x 10^14 Hz

Answer:

ν=4.96x10^14 Hz

Explanation:

c=λν

λ=wavelength

ν=frequency

in this problem:

c=3x10^8

λ=605x10^-9

so ν=c/λ

v=(3x10^8)/(605x10^-9)

v=4.96x10^14

Answer:

d.

Explanation:

The term known as "Nuclear Fusion" is a very important concept in chemistry and it is studied mostly under the topic or aspect of Chemistry known as or called radioactivity. Nuclear Fusion is the kind of reaction in which two or more atomic nucleus combines to for bigger ones.

There is a saying that there is no life without nuclear fusion because it is the reaction that causes the stars to have light.

Option 'd' is correct. This is what happens in stars in order for light to be produced that is the inward movement of gravity and the outward movement of nuclear fusion.

Answer:

The solvent is water

Explanation:

The solvent is the substance in the mixture that is able to dissolve the other substances. The solvent is usually the liquid.
