A cross between a chicken and a turkey is called a "turkin." They are raised in farms in Wyoming. The "turkin" is an example of hybridization.
The range of evidence in firearms-related cases can be as small as a piece of a bullet fragment which has rifling marks or as large as hundreds of bullets and cartridge cases and numerous firearms. Even from small samples, information can be developed to indicate the type of firearm used and possibly identify the actual firearm that was used.
Other firearms evidence that could be found at a shooting scene includes shotshell wads and shot pellets; these can indicate the gauge of the shotgun. Wads and pellets can be gathered and preserved in the same manner as bullets and cartridge cases.
By examining wadding materials, the examiner may be able to determine
- The gauge of the shotgun
- The manufacturer or marketer
- A range of possible shot sizes based on impressions in the shotshell wad
- individual characteristics (in some cases)
Eukaryotic cells have a nucleus
Answer:
Responses to stress are attributed to activation of the sympathetic nervous system and are mediated by adrenal medulla which is the central portion of the adrenal gland.
Explanation:
<em><u>Stress</u></em> is a physical, mental, and emotional response to a <em><u>threat</u></em>, and causes bodily and mental tension. There are different causes of stress, for example, an exam, a divorce, moving from a house, being fired, somebody’s death.
The body’s stress response is mediated by the sympathetic nervous system (SNS), and the hypothalamic-pituitary-adrenal (HPA) system. The SNS is responsible for the neural<u><em> </em></u><em>fight-or-flight response</em> to stress.
In a stressful situation the <u><em>hypothalamus</em></u>, which is in charge of the stress response, sends signals to the pituitary gland and the adrenal medulla. The adrenal medulla secretes the neurotransmitters and hormones adrenaline and noradrenalin to the bloodstream. These hormones get the body ready for a response to stress, by<em> increasing heart biting</em> frequency and strength, i<em>ncreasing blood pressure</em>, <em>stimulating respiration</em>, and <em>dilating respiratory tracts</em>.
Once the threat factor is over, the body gets back into a balanced state.
The animals that cannot adapt to their changing enviroment will not be able to survive and reproduce.
