What are the dangers of eating unhealthy foods besides becoming fat?
Lelu [443]
Besides becoming fat, fats may stick within the walls of your blood vessels, mainly arteries and clog blood flow from your heart to other parts of the body... putting more strain on your heart to pump blood. There is also the possible risk of diabetes from high intake of glucose and increased strain on the liver to detoxifies the harmful components in unhealthy foods

When does a wheel and axle have a mechanical advantage greater than one ?
Dima020 [189]
Great question!

<span> mechanical advantage is the factor of which a machine multiplies the force put into it. For example, if a simple machine has a mechanical advantage of 3 it means that it made the work you did 3 times easier or you only had to put in 1/3 the force you would have if you didn’t have the simple machine.
</span>
To calculate the mechanical advantage of a wheel and axle you must divide the radius of the wheel by the radius of the axle.<span>Therefore larger wheels means that the speed of the wheels is faster than the speed of the axle and for each rotation the axle makes the wheels are making multiple rotations. A mechanical advantage of 5 means that the wheels are moving 5 times faster than the axle.
</span>
<span>F = MA= radius of wheel/radius of axle</span>, this is 1 when the radius of both the wheel and axle are the same,and greater than one when the radius of the axle is less than the radius of the wheel.

Provides x 10 magnification; used to view the specimen *<br><br> 1
ValentinkaMS [17]

Answer:

The objective and ocular lenses are responsible for magnifying the image of the specimen being viewed. So for 10X objective and 10X ocular, Total magnification = 10 X 10 = 100X (this means that the image being viewed will appear to be 100 times its actual size).

A plant breeder has determined the following variances for yield of corn in his fields:
Law Incorporation [45]

Answer:

A. VG = 80

B. Broad sense heritability = 0.80

C. Narrow sense heritability = 0.30

D. Average yield = 430 Units

Explanation:

A. Given that

VA = 30

VD = 50

VI = assumed not available

Therefore

Total genetic variance (VG) = VA + VD

= 30 + 50

= 80

VG = 80

B. Given that

VP = 100

VG = 80

Broad sense heritability, H2 = VG/VP

= 80/100

= 0.80

C. Given that

VA = 30

VP = 100

Narrow sense heritability, h2 = VA/VP

=30/100

= 0.30

D. The difference in selection = 500 - 400

= 100

Recall,

Selection response is heritability multiplied by selection differential.

That is

R = h2S

Selection differential = 100

Heritability h2 = 0.30

Selection response = 0.30 × 100

= 30units

Therefore, expected average yield = 400 + 30

= 430 Units
