Answer:

Darwin and Lamarck were both scientists who tried to understand evolution. ... Darwin's theory became accepted because it had more evidence that supported it. Lamarck's theory suggest that all organisms become more complicated over time, and therefore doesn't account for simple organisms, such as single-cell organisms.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe

dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.

The equation can be written as, $F= K \frac{ q_{1} q_{2} }{r^{2} }$ where k is the Coulomb constant, $q_{1} q_{2}$ are the point charges, and r is the distance between these two point charges.
To find the answer to this question, just substitute 2r in the place of r hence, you will get $\frac{F}{4}$ as the new force when the distance is doubled.

Are involuntary muscles striated?

alukav5142 [94]

<span>No.The involuntary muscles of the muscular system are not striated or furrowed.

</span>
<span><span>These muscles that are not striated are very smooth to the sight which is why they are also called Smooth muscles.</span> Involuntary muscles are not striated. Even among the striated muscles that are voluntary, the heart which is also a muscle, is involuntary.
On the other hand the striated muscles, which are voluntary are highly fibrous and their primary function is to move the body voluntarily, and producing heat as a result of this muscle action. </span>

The pedigree below tracks the presence of dimples through a family's generation. Having dimples is an autosomal dominant trait.

yulyashka [42]

A pedigree is a representation of a family history tracking a trait. The graph shows the inheritance pattern of the trait and its expression through several generations.

<h3>What is an autosomal dominant trait?</h3>

The autosomal dominant trait is the characteristic that is coded by a gene located in an autosomal chromosome (this is, not a sexual chromosome).

This trait is dominant because it is coded by the dominant allele, meaning that the recessive allele codes for the absence of dimples. The presence of only one dominant allele in the genotype is enough for the idividual to express dimples.

<u> Genotype Phenotype </u>

DD, Homozygous dominant Dimples

Dd, Heterozygous Dimples

dd, Homozygous recessive No Dimples

<h3>What is a pedigree?</h3>

The pedigree is the representation of a family history conserning a certain trait. In this case, dimples.

The pedigree shows the expression -and inheritance pattern- of the trait through several generations.

To correctly interpret a pedigree, we need to know that

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

Here we will assume that

Individuals represented with solid figures express dimples -shaded individuals-. They can be either DD or Dd. This is because dimples is not usuall.

Individuals with no dimples are represented with empty figures and are dd.

According to the provided pedigree,

I-1 ⇒ man DD or Dd

I-2 ⇒ woman dd

II-1 ⇒ man Dd or DD

II-2 ⇒ woman dd

II - 5 ⇒ woman dd

III - 1 ⇒ man Dd

III- 2 ⇒ woman dd

III - 6 ⇒ woman dd

Since this pedigree does not specify the relationship between individuals, I can not answer the question based on it. So, I will attach another tree to specify genotypes.

I advise you study this new example, and then follow the same reasoning to choose the correct individual according to you pedigree.
