I think the answer is D Ellipitical galaxy
The layer of connective tissue, called the _perimysium_ , extends inward from the epimysium and separates the muscle tissue into small sections. these sections contain bundles of skeletal muscle fibers called _fascicles_ .
Additionally, bundles of contractile proteins called fibrils fill a muscle cell, called a fiber. Outside of each fiber, is the connective tissue endomysium. Bundles of fibers form fascicles, surrounded by perimysium. Bundles of fascicles and perimysium comprise the entire muscle organ, which is enclosed by epimysium.
Answer:
Posterior column mediates a pathway called as posterior column medial lemniscus pathway in central nervous which is responsible for mediating certain sensations like touch, vibration etc. Damage to the left posterior column unable to transmit signals to the primary somatosensory cortex in the gyrus and parietal lobe of the brain.
Explanation:
- The spinal cord and cerebrum is connected by some specialized tract called as white matter tract. These tracts are either ascending or descending.
- The another name of ascending pathway is known as medial lemniscus pathway.
- The origin of this pathway takes place within posterior column of the spinal cord.
- Posterior column medial lemniscus pathway is important as it transmit signals to the cerebrum which is responsible for generating impulse like vibration, touch etc.
- Thus damage to this column can't be able to transmit signals to different parts of cerebrum and thus impulse like touch, vibration,pressure etc will not generate.
Answer:
37.5%
Explanation:
These here are
Black (AA or Aa) and albino (aa)
Agouti (Bb or BB)
Thus, a cross between
AaBb and aaBb
The percent of the progeny which are likely to be agouti would be
A. a. B. b
a. Aa. aa. B. BB. Bb
a. Aa. aa. b. Bb. bb
The probability of agouti would be
1/2 (Aa) * 3/4 (BB or Bb)
= 3/8
= 37.5%
B. The nervous system collects and responds to information about the external and internal environment.
