The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

The trait of extraversion often correlates around 50% for identical twins and around _______ for fraternal twins.
tresset_1 [31]
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:

If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.

Explanation:

Oil spills happen when a large quantity of oil gets mixed with large water bodies like <em>sea and oceans</em>. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.

The difference between processed oil and normal oil is that they are heated at very <u>high temperatures</u> and this results in oxidation which creates <em>free radicals</em>, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.

When oil spills happen, the <em>wind</em> cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-

  • The oil gets stuck in the feathers of the birds who come by to dip themselves,
  • Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
  • The fur of animals like <u>seal and otter </u>gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
  • The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
  • Since processed oil has longer shelf life, a large quantity of animals will suffer and die.

What is Cancer? how is mitosis related to cancer?
xxTIMURxx [149]

Explanation:

<h3>Cancer: mitosis out of control</h3>

<h3>Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. These are cancer cells.</h3>
