That would be A.
Dicots grow flowers with petals in multiplies of 4 and 5, monocots in multiples of 3. See the attached pic:)
The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of tectospinal, reticulospinal and vestibulospinal tracts.
The tectospinal tract in humans, also known as colliculospinal tract, is a nerve tract that coordinates head and eye movements. This tract is a part of the extrapyrimidal system in which it particularly connects the midbrain tectim and cervical regions of the spinal cord.
The vestibulospinal tract is a neural tract found in the central nervous system. It is specifically also a component of the extrapyramidal system and is a classified component of the medial pathway. The vestibulospinal fibers of the tract relay information from the nuclei to the motor neurons which is the same with the other descending motor pathways.
Lastly, the reticulospinal tracts or the descending or anterior reticulospinal tracts are extrapyrimidal motor tracts that goes down from the reticular formation in two tracts to act on the motor neurons supplying the trunk and the flexors and extensors of the proximal limb.
Answer: B) The opposing force of friction stopped the train.
Explanation:
From Newton's first law of motion, we know that an object remains in the state of rest or constant motion unless and until acted upon by an unbalanced net force.
Here, the rolls to a stop along a horizontal track without application of break. There is absence of an applied force. It means that a force of friction acting in the opposite direction of motion train eventually brought it to rest state. Hence, the correct option is B.
I think that about half of all babies are able to walk independently by 12 month of age. It said that babies tend to take their first steps from the age of 9. Babies usually start to crawl before they can walk. This is because their arm are usually more effective. After crawling they learn to stand up with their feet first and later learn to walk while holding things. The next step after that is walking.
Not all babies walk at the same time. There those that learn before the other so there is no need to worry if your child does not walk by 12 months.
TRUE.
