A person has polydactyly (extra fingers or toes). Polydactyly is caused by a dominant allele.

Helen [10]

Answer:

1 I think, read the explanation.

Explanation:

Offspring need to carry just one dominant allele from their parents to inherit the polydactyl condition. The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet

How can hybridization be used to produce plants with characteristics needed to increase food production

Setler79 [48]

<span>hybridization can be used to produce plants giving a high yield by breeding an indigenous variety of the plant having disease and pest resistant qualities and also a greater adaptability to the particular environment with a high yielding exotic variety to get an offspring having the desired qualities of both and also promoting hybrid </span>

Which health care provider assessment technique does the nurse anticipate being used to determine developmental dysplasia of the

Arlecino [84]

A nurse can identify possible developmental dysplasia of the hip (DDH) during a newborn assessment through asymmetry of the gluteal folds. Asymmetrical buttock creases can suggest hip dysplasia in infants but an ultrasound or x-ray study will need to be done to determine whether the hips are normal or not just like a hip click.

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m

Vanyuwa [196]

This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

<span>Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
$v=\frac{2\pi{r}}{T}$
</span> $=\frac{2\pi{r}}{1.88*365.25*86400}$ m/s, accounting for leap years
$=3.371*10^{-8}\pi{r}$ m/s

The centripetal force, Fc, generated is
$Fc=\frac{mv^2}{r}$
where m=mass of mars = 6.39*10^(24) kg
$=\frac{mv^2}{r}$
$=\frac{6.39*10^{24}v^2}{r}$
$=7.26168*10^9\pi^2r$

The gravitation pull from the sun, Fg, is given by
$Fg=\frac{GMm}{r^2}$
where G=grav. const., =6.67408*10^(-11) m^3<span> kg^(</span>-1)<span> s^(</span>-2)
M=mass of sun=1.989*10^(30) kg
$=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}$
$=\frac{8.4826*10^44}{r^2}$

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
$7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}$
Solving for the real root:
$r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}$
$=\frac{1.1681263*10^{35}}{\pi^2}$
=2.279*10^11 m
