Answer:
Physiological reactions to stress in the alarm stage include: <em>increased heart rate and blood pressure, dilated pupils, rapid and shallow breath, and increased cortisol levels.</em>
Explanation:
Hans Seyle, a medical doctor proposed a model called the General Adaptation Syndrome (GAS) to explain the effects and stages of coping with the stress. The GAS model has three stages, known as:
1. Alarm stage
2. Resistance stage
3. Exhaustion stage
The <em>alarm</em> stage is the first stage of responding to stress. During this stage, the fight-or-flight response is activated when an individual is experiencing stress. This stage involves the following physiological reactions:
1. Increased heart rate
2. Increased blood pressure
3. Dilated pupils
4. Rapid and shallow breath
5. Increased cortisol levels
Answer:
Karyotype- Abnormal
it's a Trisomy of the X chromosome: it's a form of aneuploidy
The disorder is called Triple X syndrome. It's characterized by tall stature, vertical skin folds, poor muscle tone, and a curve in the 5th finger towards the 4th and small head (microcephaly),
During meiosis 1, prophase 1 Each chromosome form tetrads and and become more and more condensed. This is when crossing over occurs. So your answer is B.
