Answer:
Previous research has quantified differences in head and spinal kinematics between children and adults restrained in an automotive-like configuration subjected to low speed dynamic loading. The forces and moments that the cervical spine imposes on the head contribute directly to these age-based kinematic variations. To provide further explanation of the kinematic results, this study compared the upper neck kinetics - including the relative contribution of shear and tension as well as flexion moment - between children (n=20, 6-14 yr) and adults (n=10, 18-30 yr) during low-speed (<4 g, 2.5 m/s) frontal sled tests. The subjects were restrained by a lap and shoulder belt and photo-reflective targets were attached to skeletal landmarks on the head, spine, shoulders, sternum, and legs. A 3D infrared tracking system quantified the position of the targets. Shear force (F(x)), axial force (F(z)), bending moment (M(y)), and head angular acceleration (θ(head)) were computed using inverse dynamics. The method was validated against ATD measured loads. Peak F(z) and θ(head) significantly decreased with increasing age while M(y) significantly increased with increasing age. F(x) significantly increased with age when age was considered as a univariate variable; however when variations in head-to-neck girth ratio and change in velocity were accounted for, this difference as a function of age was not significant. These results provide insight into the relationship between age-based differences in head kinematics and the kinetics of the cervical spine. Such information is valuable for pediatric cervical spine models and when scaling adult-based upper cervical spine tolerance and injury metrics to children.
Answer:
The answers are explained below:
- Black rough fur -
. - Black smooth fur -
. - White rough fur -
. - white smooth fur -

Explanation:
- The genotype of homozygous black fur and smooth texture: BBrr.
- The gametes produced are : Br
- The genotype of white and heterozygous for rough texture: bbRr
- The gametes produced are : bR and br.
- The cross,
bR br
Br BbRr Bbrr
(B/R) (B/S)
- B - Black.
- R - Rough.
- S -Smooth.
- The cross can develop two types of offspring, that is,
- Black and Rough (BbRr) - 1.
- Black and smooth (Bbrr)- 1.
- Black rough fur -
. - Black smooth fur -
. - White rough fur -
. - white smooth fur -

<span>The rat was taught that when you press the bar you receive food. When the food ran out the rat was still pressing the bar however it wasn't be awarded. The rat then saw that there was no outcome to pressing the button therefore found it to be pointless.</span>
Answer:
A) unsaturated fatty acids
B) omega-3 fatty acids
C) saturated fatty acids
Explanation:
Monounsaturated fat — found in olive, peanut and canola oils — is a healthier option than is saturated fat. Nuts, fish and other foods containing unsaturated omega-3 fatty acids are other good choices of foods with healthy fats.

It passes the Roche limit a break due tidal force.
Explanation:
The name Roche limit is due to famous scientist Edouard Roche. It is known as the minimum distance which is smaller object can exist and as a body held together by itself gravity. Roche limit is also called Roche Radius.
Its minimum distance is from the center of the planet. For formation it allows the material to come together. The example is large enough moon.
