Achondroplastic dwarfism is a dominant genetic trait that causes severe malformation of the skeleton. Homozygotes for this condi

tion are spontaneously aborted (hence, the homozygous condition is lethal) but heterozygotes will develop to be dwarfed. Matthew has a family history of the condition, although he does not express the trait. Jane is an achondroplastic dwarf.
Matthew and Jane are planning a family of several children and want to know the chances of producing a child with achondroplastic dwarfism. If three children are born to Matthew and Jane, what are the chances that the first two children will not express the trait but that the third child will be an achondroplastic dwarf.

Explanation:

A punnet square can be described as a diagram which is used to illustrate the results of a cross. As the condition described, Mathew does not have Achondroplastic dwarfism hence he will have recessive alleles, aa. Jane has the condition so she will have the allele Aa ( as the child with both AA is aborted). The punnet square for a cross between hem can be drawn as follows:

        a                 a

A    Aa                Aa

a      aa               aa

<em>There is 1/8 chance that the first two children will not express the trait but that the third child will be an achondroplastic dwarf.</em>

Based on this document, do you think John Brown was a “misguided fanatic”? Why or why not?
elena55 [62]
There's no document provided, I'll answer to the best of my knowledge
The abolitionist John Brown attempted to garner attention and do his part to abolish slavery by murdering three individuals who supported slavery, and later tried to host an armed uprising where he would lead slaves to raid a federal army in Harper's Ferry. The attack was unsuccessful, and he was later executed. His actions were radical, and in my opinion very misguided and would only lead to more violence.

That is my take on it, though I recommend you get your own opinion because that is a very opinionated topic.

This ANSI laser____________ is harmful through direct exposure and from mirror light reflections. It emits visible and invisible
omeli [17]

Answer:

Class 3B

Explanation:

The Class 3B laser products are well thought-out to be more harmful and relatively dangerous under straight and spectacular reflective viewing conditions. A Class 3B laser product, however, is on the whole not a fire hazard, diffuse reflection hazard or a laser generated air contaminant (LGAC) production hazard but could be hazardous when under mirror light reflection.

Based on the theory of Leon Festinger, the state of conflict that someone experiences after taking an action, making a decision,
Shtirlitz [24]

Answer:

Cognitive dissonance

Explanation:

The term Cognitive Dissonance was first introduced by Leon Festinger and it refers to what happens when a person has two or more contradictory beliefs or ideas and experiences psychological stress because of that. In other words, when two ideas are opposite to each other, the person will experience stress and will try to reduce this difference to reduce their discomfort. This usually happens when <u>new evidence contradicts the person previous belief and it creates stress</u> (cognitive dissonance).

Therefore, the state of conflict that someone experiences after taking an action, making a decision, or being exposed to information that is contrary to his or her beliefs is known as cognitive dissonance.
