The dot plot shows the number of songs in a play list. Determine the mean of the data set. A) 39 B) 40 C) 41 D) 42

2 answers:

6 0

To calculate the mean all you have to do is add all the numbers from the data set and then divide the answer between the number of data set. For example, if you data set is 2,3,4,5,6,then you add 2+3+4+5+6=20 Now you divide 20 between the total number of data, so from 2 to 6 you have 5 numbers. You divide 20/5 and that that is equal to 4.

Since you did not post your data set I can not tell you exactly the answer but you can use this information to walk you through it.

Answer:

Explanation:

The " mean" is the average of a set of numbers .

25 + 36 + 38 + 38 + 39 + 39 + 40 + 40 + 40 + 42 + 42 + 42 + 45 + 47 + 47 Divide by 15 = 600 /15 = 40

Analyze how a point mutation can affect the overall protein shape and function, using hemoglobin as an example.

aniked [119]

Answer:

A point mutation can be described as a mutation in which changes occur in a single nucleotide. A nucleotide may get changed, deleted or inserted from the sequence of DNA. Point mutations can be harmless or harmful depending on the nucleotide in which the changes occur.

A change in just one nucleotide can result in the formation of wrong amino acid and hence changed or wrong proteins can be formed. If the original protein was involved in cellular reproduction, then the entire process of reproduction can be affected by a point mutation.

Sickle- cell anaemia is a disease in which the body fails to produce enough healthy red blood cells. This disease occurs due to point mutation. Point mutation occurs where glutamine (GAG) of the β-globin gets changed into valine (GUG). This change causes the haemoglobin to get a deformed structure due to which it is not able to carry out oxygen.

Write a sientific explanation describing how light ando sound energy help us communicate and share information our daily lives.

Gekata [30.6K]

Answer: There are many sources of light, but the initial energy for all light sources comes from the sun. Light travels away from its source in straight lines through space as waves of energy. The waves we can detect with our eyes are called visible light. Patterns in the behavior of light are predictable because light moves in waves through space until it comes in contact with an object or material that changes its direction. Light can pass through or bounce off objects. Additionally, different materials can block or absorb light. If an object blocks light, a shadow of the object forms. If the intensity or direction of the light source changes, the appearance of an object’s shadow can change in size, shape, or darkness. Absorbing light energy can cause changes in matter. A common example includes the color of paper or fabric fading as the matter absorbs light over time. Vibrations cause sounds. We can hear when sound waves travel through the air to our ears and cause our eardrums to vibrate. Sound can also travel through other forms of matter, such as liquids and solids.

Most extinction is ________.

Maksim231197 [3]

An extinction event is a well-known and quick decrease in the biodiversity on Earth. Such an occurrence is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the rate of extinction surges with respect to the rate of speciation. In other words, this happens when species cannot adapt generally to the change in the environment. So the correct answer would be letter a.

Can anyone tell me the ratio of the genotype and phenotype ???

iogann1982 [59]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Phenotype:</h2>

It is the physical appearance of the trait, whether the person has smooth chin or cleft chin.

<h2>Genotype:</h2>

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or hom.ozygous, recessive or dominant.

<h2>_____________________________________</h2><h2>Alleles:</h2>

Cleft chin C is dominant over smooth chin c

<h2>Genotypes of Parents:</h2><h3>FATHER:</h3>

Father has smooth chin thus, it is hom.ozygous recessive i.e. cc

<h3>MOTHER:</h3>

Mother has cleft chin, since cleft chin is dominant there are two possibilities of her genotype,

Heterozygous Dominant : Cc

Hom.zygous Dominant : CC

but if we cross the hom.zygous fominant mother to hom.ozygous recessive father we will get all the offsprings with the same genotype phenotype so it is not possibile, So the mother is HETEROZYGOUS DOMINANT Cc

<h2>_____________________________________</h2><h2><u>Question</u>:</h2><h2>_____________________________________</h2><h2>Genotypes of Parents:</h2>

FATHER: cc (Hom.ozygous Recessive)

MOTHER: Cc (Heterozygous Dominant)

<h2>_____________________________________</h2><h2>Punnet Square:</h2>

Picture attached!

Picture no 1: it is the cross between hom.ozygous recessive father and hom.ozygous dominant mother and all the offsprings are same both phenotypic and genotypic way so IT IS NOT POSSIBILE

Picture no 2: Its cross between hom.ozygous recessive father and heterozygous dominant mother and there are hybrid and pure recessive both type of offsprings present thus IT IS POSSIBLE!

<h2>_____________________________________</h2><h2>Genotype Ratio of the Offspring:</h2>

Hybrid : Pure Recessive

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Phenotype Ratio of the Offspring:</h2>

Cleft Chin : Smooth Chin

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Best Regards,</h2><h2>'Borz'</h2><h2 />
