The word extraversion is popularized by Carl Jung and defined it as "an attitude type characterized by concentration of interest on the external object (focuses on the outside world). Contemporary psychologists classified the dimensions of personality into five, which is referred to as the "BIG 5" personality traits. The BIG 5 are broad categories personality traits and though there are significant body of literature supporting this five-factor model personality, researches do not always agree on the exact labels for each. It will be helpful to remember the word OCEAN as an acronym for these "BIG 5" personality traits: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. Extraversion is one of the "BIG 5" personality traits an is characterized by excitability, sociability, talkativeness, assertiveness and high amount of emotional expressiveness. Extroverts are outgoing and gain energy in social situation. They tend to: enjoy being the center of attention because they get energized when they are around people, like to start conversations, enjoy meeting new people, have a wide social circle of friends and acquaintances because they find it easy to make friends and say things before they think about them. A published journal by Stephanie M. van den Berg, et al., entitled Harmonization of Neuroticism and Extraversion phenotypes across inventories and cohorts in the Genetic Personality Consortium: an application of Item Response Theory (IRT), studied on the heritability of extraversion in twins. The IRT-based scores for Neuroticism and extraversion were heritable, with 48 and 49% respectively, based on the meta-analysis of six twin cohorts with a significant part of the heritability due to non-additive genetic factors. For extraversion particularly, these genetic factors differ across sexes. So whether identical or fraternal, it correlates around 49-50% but will differ only across sexes, that is, whether male or female.
Answer:
Cerebrospinal fluid circulates within the ventricles of the brain and in the subarachnoid space is called Cerebrospinal fluid circulation
Explanation:
CSF is formed within the ventricles by small, delicate tufts of specialized tissue called the choroid plexus
the major pathway of CSF flow. Beginning in the lateral ventricles, CSF flows through two passageways into the third ventricle. From the third ventricle it flows down a long, narrow passageway (the aqueduct of Sylvius) into the fourth ventricle. From the fourth ventricle it passes through three small openings (foramina) into the subarachnoid space surrounding the brain and spinal cord
1. The right answer is gymnosperm.
The term gymnosperm comes from the Greek gumnospermos meaning "bare seed". It refers to plants that are part of a subphylum of spermaphytes, seed plants. The hallmark of gymnosperm plants is that their ovum is bare (not enclosed in an ovary unlike angiosperms) and receives pollen directly. It is carried by a fertile leaf or scales more or less open.
2. The right answer is A.
Angiosperms are plants whose reproductive organs are condensed into a flower and whose fertilized seeds are enclosed in a fruit, unlike gymnosperms whose seed is bare. Thus, angiosperms are commonly called "flowering plants".
3. The right answer is C
A fern designates a filicophyte, a pteridophytic plant vascularized without flower or seed, consisting of a rhizome producing aerial stems whose large fronds, equivalent to the leaves, bear sporangia on their underside.
By definition, a fern is a cryptogam belonging to a group of about 12,000 species of vascular plants that reproduce by spores and have no seeds or flowers.
4. The right answer is seeds.
Spermaphytes (which include gymnosperms, chlamydosperms, and angiosperms) are the first seed plants to appear on the surface of the globe. They are distinguished from other plants (bryophytes and pteridophytes), among others, by aerial reproduction via pollen.
