____ [38]
There are two types of neurons in our legs: motor neuron and sensory neuron. These send and receive messages to and from each other and the brain.  

After Ed's accident, he can't move his injured leg since the motor neuron is dysfunctional. The sensory neuron is functional so he can feel his limbs but can't move them since when the sensory neuron sends a message to the motor neuron, it isn't able to deliver the message to the brain to make the leg move. This is why he can still feel his limbs but is not able to move them.

Hypersecretion of prolactin from the anterior pituitary gland causes the condition of ________. dwarfism postpartum hemorrhage g
kolbaska11 [484]

Hypersecretion of the population from the anterior pituitary gland causes the condition of galactorrhea.

Prolactin is another name is called luteotropin and its main function is to enable mammals mostly female to produce milk. The pituitary gland secretes it in response to mating, estrogen treatment, ovulation, nursing and eating.

The pituitary gland is attached to the hypothalamus by a short stalk. The pituitary gland has two major parts.

(i)                  An anterior lobe

(ii)                Posterior lobe.

The pituitary gland is controlled by hormones and neurons that comes in the hypothalamus where it acts as a link between brain and endocrine system, and hypothalamus is the endocrine gland itself. Hypothalamus has neurons which regulate secretion of anterior lobe hormones by secreting inhibit and releasing  hormones. Every hormone produced by anterior lobe has a releasing hormone.

Prolactin and growth hormones have inhibiting hormone. Releasing hormone helps in stimulating production and it releases hormones from the anterior lobe.

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.

State the role of mirror​
kvv77 [185]

Answer:

Mirrors are essential to every home. They help us in our daily mundane lives, though we rarely ever really appreciate their usefulness. From the moment we get up at night to the time we ready ourselves for sleep, we almost always seek for a mirror to take a look at ourselves. Mirrors reflect to us how we look, how clothes fit us, and how things fit.
