Semi-conductors can best be described as materials that are neither normal conductors (substances that conducts electricity such as copper) or normal insulators (substances that does not conduct electricity such as rubber), but have some of the properties of both. Semiconductors that do not contain impurities do not conduct electricity but the addition of some elements to them allows easy passage of electricity through them. Examples of semi-conductors are silicon, germanium, and selenium.

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fi

valkas [14]

Answer:

50% of their children are likely to be carriers of cystic fibrosis

Explanation:

Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.

Montano1993 [528]

Answer:

Length of the cells = diameter of field of view/ number of cells across the field of view

Explanation:

therefore 2.25= 4.5*X

X= 2.25/4.5

=0.5 number of cells

Can someone help me with this ASAP!

madreJ [45]

Answer:

The answer is C.

Explanation:

There are dominant alleles present in three out of four (CC, Cc, Cc) and the recessive is always cc. Three out of four make 75% and one out of four is 25%. That makes 75% dominant and 25% recessive.

I hope this helps!
