Answer:

Option C, Analogous Organ

Explanation:

Thorns and spines are analogous organs. Analogous organs are those which have different function but have similar look and structure.  

Thorns are basically modified stem and spines are modified leaves. Both the thorns and spines are different in structure but they have same function which are as follows -  

a) They control the rate of respiration

b) Provide protection to the plants

The correct option is ANALOGOUS STRUCTURES.
Analogous structures are structures that are similar because of the functions they carry out and because of their external appearance. But these structures are different internally.<span />

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.

Umnica [9.8K]

Answer:

Genetic mapping for unequivocal identification of the potentially causative mutation  

Explanation:

Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.

How does the frogs vestigial thumb help survival?
Leviafan [203]

Frogs have their way of avoiding the predators like camouflage, squirting the poisonous liquid out of their system and through their vestigial thumbs. This organ helps them by avoiding predation by stealth which makes them quiet and silent in moving so that predators won't notice them readily.
