Answer:
It would be the second one! All diagrams of this show the second kind of cell, as its a prokaryotic cell, which have a nucleus.
Explanation:
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.

<span>The model of modern human origins depends, in part, on the archaic interbreeding of Neanderthals and Homo Sapiens (not the modern Homo Sapiens Sapiens, which is what human beings are to this day.) From this coupling rose a species, us, which was tough and less impervious to cold, a quality gained from the Neanderthals, and a more robust brain size, a quality obtained from Homo Sapiens.</span>
The correct answer is option A
The major advantage of DDT at that time when it was used as a pesticide is that the DDT was very effective as a pesticide and it killed almost all the pests on which it was sprayed. It killed all the insect and pests that was present in the united states at that time. It later became harmful and entered into the food web.
