Answer:
a. paraplegia
b. paraplegia (it is repeated)
Explanation:
• Paraplegia T1-T9 (Requires assistance at least 3 hours a day). People with lesions from T1 preserve innervation and, therefore, the function of all upper limb muscles. They can achieve functional independence, not only in self-care and mobility activities, but also in certain light domestic activities. From this level of injury, an intensive training to carry the manual wheelchair through irregular terrain, slopes and ramps is feasible. From the T6 lesion the patients present a better trunk control. In addition, with proper training, they can make transfers from the floor to the chair. People with injuries between T2 and T9 can achieve prophylactic standing with parallel bitters, with the support of a walker or crutches.
• Paraplegia T10 L1 (Requires assistance at least 2 hours a day) Patients with injuries from T10 have normal breathing with normal vital capacity. As with T1-T9 lesions, they are independent in activities of daily living, sphincter care and transfers. This group of patients is able to perform independent standing and assisted therapeutic walking. Unfortunately for all these activities, energy expenditure is excessive and joint wear of the upper limbs is important. Patients remain dependent on a self-propelled wheelchair for travel.
Answer:
C. Standing upright allowed for sightlines over tall grasses and savanna shrubbery
Explanation:
One of the most accepted theories about the development of bipedalism of the hominids is that it was mostly because of the tall grasses and shrubs, so standing upright was providing them with better view. Once the environment changed, and the tropical rainforest was turned into savanna, the hominid ancestors had to adapt in order to survive. Being helpless against the large predators, they needed something in order to be able to detect them from bigger distance so that they can avoid them. The solution seemed to be to be able to see above the tall grasses and shrubs, which meant that they started to use their legs more and more in order to stand up taller. This gradually led to better development of legs for upright standing and walking, also causing changes in the structure of the body, providing the hominids with an adaptation that enabled them to survive in the very dangerous environment.
<span>It is vitally important to life, any form of life. Life in it's self is what we are all striving to grasp, hold and not let escape. It is the endless search for meaning to understand and comprehend.
Evolution which is the symphonic struggle of nature to overcome and create the most suitable specimen ensuring its survival within its species from its predators and the world at large.
Duplication is natures way to regenerate and strengthen the gene pool of species. It allows newer generations to improve on the genes to enable it to adapt better to the current environment is is facing. It is a constant and never ending process.</span>
Answer:
32 cells
Explanation:
In each mitotic division, from one cell you are going to have at the end 2 cells. That means that to calculate the number of cells you need to use the formula 2n so 2 at the 5th power will it be 32. In the embriotic process this is called morula by the number of cells.
