Answer:
The answer is Pelvic.
Explanation:
The following are groups of vertebrae: cervical, thoracic, lumbar. The pelvis is not part of this group. The pelvis is located at the bottom of the trunk. It is a funnel-shaped cavity (musculoskeletal) that narrows downward, limited by the sacral bone, the coccyx and the coxals, thus forming the pelvic girdle and the muscles of the lower abdominal wall and the peritoneum.
Answer:A particle has zero velocity initially (i.e., at time
t=0
t=0
) and its acceleration at
t
t
seconds is
a(t)=72t−4
t
3
a(t)=72t−4t3
meters-per-second per second. During the time interval
[5,8]
[5,8]
seconds find the average acceleration and the average speed of the particle. I got the average acceleration by taking the integral and then plugging that into
f(8)−f(5)/8−5
f(8)−f(5)/8−5
but I have tried working through the average speed and I can't find the answer for that one.
Explanation:
Answer:
Invertebrates: Do not possess a backbone and doesn't have an internal skeleton. Has an exoskeleton. Are generally smaller than vertebrates. Possess an open circulatory system. The majority have compound eyes. Includes radial or bilateral body symmetry. Presence of a simple and unorganized nervous system. Mode of nutrition includes Autotrophic, Parasitic, and Heterotrophic. 95% of animal species are invertebrates. Flatworms, arthropods, sponges, insects are few examples of Invertebrates.
Vertebrates: Possess a backbone and has an internal skeleton. Does not have an endoskeleton. Larger than invertebrates. Possess a closed circulatory system. Do not have compound eyes. Has bilateral body symmetry. Presence of complex and highly specialized organ systems with specific functions. The mode of nutrition is usually heterotrophic. 5% of animal species are vertebrates. Mammals, fish, reptiles, amphibians, and birds are examples of Vertebrates.
A person who specializes in the study of animals is called a zoologist. Zoologists who study certain kinds of animals have their own names.
Because there's such thing as good bacteria.
