What embryonic structure gives rise to the centrum?
Gnesinka [82]
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.

Suppose a one-year old child is playing with a toy near an electrical out-let. He sticks part of the toy into the outlet. He get
Papessa [141]

Answer:

UCS: sticks part of the toy into the electrical outlet

UCR: frightened and crying

CS: toy

CR: frightened to toy

Explanation:

Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.

<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.

<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.

Scientists are researching a large family, many of whose members have Jackson-Weiss Syndrome, a disease that causes bone problem
Goryan [66]

The right answer is C.

A genetic disease is called autosomal dominant transmission when :

* The morbid allele ("sick" version, mutated of the gene in question) is on a non-sexual chromosome (neither X nor Y).

* The presence of a single morbid allele is sufficient for the disease to express itself.

The morbid allele is transmitted by either the father or the mother (or both, if they have the same inherited autosomal dominant genetic disease). Anyone with one of their affected parents is affected.

Jackson-Weiss syndrome is indeed an autosomal dominant disease characterized by a malformation of the feet, craniosynostosis of varying degrees, facial abnormalities, enlargement of the big toes and normal hands.
