Which bone connects the shoulder to the forearm?

dezoksy [38]

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individ

Ne4ueva [31]

Answer:

The following four traits are -:

Pedigree 1 - A recessive trait (autosomal recessive) is expressed by pedigree 1.
Pedigree 2- Recessive inheritance is defined by Pedigree 2.
Pedigree 3 - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
Pedigree 4- An X-like dominant trait is expressed by Pedigree 4.

Explanation:

Explaination of each pedigree chart-

Pedigree 1 demonstrates the recessive trait since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. $X^A$ In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
Recessive inheritance is defined by Pedigree 2. This is X-related inheritance as autosomal recessive inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes ( $X^A$ ) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical $X^A$ must be contributed by II-6.
The inheritance of the dominant trait is demonstrated by Pedigree 3 because affected children still have affected parents (remember that all four diseases are rare). The trait must be autosomal dominant because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
Pedigree 4 is an X-linked dominant function characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.

In the question the pedigree chart was missing ,hence it is given below.

Find the unit rate with the second given unit in the denominator.

Kobotan [32]

First, the unit is words per minute, not the other way round because you're interested in how fast people can type, not how much time passes for every number of words they write or read (that would be minutes per word)

now, we know they do 4200 in 60 minutes.

we need to divide 4200 by 60- first, $\frac{4200}{60} = \frac{420}{6} = \frac{21}{3} =70$

so the answer is, 70 words per minute

I think you made a typo in your answer and you meant 4600 instead of 4200 - then the answer is C. 76 2/3 word/min

Which part of the cell is affected by the movement of molecules through diffusion, osmosis and active transport?

kolezko [41]

Ans.

Diffusion, osmosis, and active transport are mechanism of cellular transport that involves movement of molecules through plasma membrane. Diffusion shows movement of small, hydrophobic particles without the help of protein molecules through cell membrane along the concentration gradient.

Osmosis involves movement of water molecules against concentration gradient (from an area of high solvent concentration to an area of low solvent concentration) through cell membrane.

Active transport shows movement of particles, against the concentration gradient, means from a region of higher to lower concentration of molecules through cell membrane. It involves transport through membrane proteins.

Thus, the part of cell, which is affected by the movement of molecules through osmosis, diffusion, and active transport is cell membrane or plasma membrane.
