Answer: (B) shared, derived traits.

Explanation:

In phylogenetic systematics, which presents itself with a character that eventually changes in descent, and presents itself with variations, which subsequently convert in the next generations. In this way, the character presence is not unique to the ancestor, but also in all heirs, however with a possible variation. This new variation or new character state is recognized as a derived condition, arose from the change in the state of the ancestral character. A derived condition has the potential to serve as a determinant for defining a new group is called apomorphy. An apomorphy can be unique to a group and is called a case of autapomorphy, or when it is shared by two or more groups it is called synapomorphy.

Match the following terms and definitions.

1. Short-term hormonal influences on animal behavior usually occurring late in life  - activational effects

2. A technique that associates a natural response to a stimulus to an unrelated stimulus; also called Pavlovian conditioning  -- classical conditioning

3. The study of animal behavior in its natural environment  - ethology

4. When an animal learns not to respond to a stimulus  - habituation

5. Finding a solution to a once unsolvable problem  - insightful learning

6. Learning that has taken place but is dormant until a situation requires it  - latent learning

Explanation:

Activational effects are the sudden or immediate temporary transient effects of behavioral changes due to the influence of hormones, especially the gonodal or the sex hormones. The behavior change in male animals due to increase in male sex hormonal activity can be referred as activational effect.

Classical conditioning facilitates learning of a behavior when a conditioned stimulus is associated with an unconditioned stimulus leading to a conditioned response. Animal training by pairing a new unconditioned stimulus with an already known conditioned stimulus, a new conditioned response of behavior change can be observed.

Ethology refers to the scientific zoological study (includes both laboratory as well as natural field studies) of animals behavior with relation to their natural environment. It studies and compares about animal behavioral processes changes under various disciplines like ecology, anatomy, evolution etc.

Habituation is an associative learning process that results when an animal learns to resist a stimulus and not to respond to it after repeated exposure.  

Insightful learning occurs when various parts of a problem is analyzed and their relationship is understood to arrive at the solution suddenly. Animals must look at a situation as a whole, observe and analyze it to solve the problem. Some animals like chimpanzees can learn through insightful learning

Latent learning occurs without any associated reinforcements. Animals learn new behavior through latent learning.

Systemic sclerosis causes antigen-antibody complexes to be deposited in the dermis. why would they be deposited here
Anni [7]
<span>The antigen-antibody that is deposited in the dermis is known as T-cells. These are protein cells that divide excessively causing the development of thick and calloused skin.

The overproduction of these cells on the dermis area causes the overproduction of collagen fibers on the skin. As the skin pushes its way up to the epridermis, the overproduction of these cells result to the symptoms that are observable for diagnosis.<span>
