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:
B. Energy needs
Explanation:
As an individual ages there is a characteristic natural loss of muscle mass that occurs and increases as they move into older years. Changes in lifestyle, such as transition from employment to retirement, also account for a decrease in energy needs. This is because there is less amount of work done during retirement than when an individual is actively working.
The less amount of work is the reason why there is also a corresponding decrease in the energy needs.
What is mitosis?
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
What is mitosis in plants?
Mitosis is a carefully controlled process that organizes and. separates the chromosomes correctly. After the cells separate the chromosomes and build new nuclei, they divide their cytoplasm by cytokinesis and form two distinct cells.
Answer:
The correct answer is-
4. true
5. Natural selection
6. microevolution
Explanation:
Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.
Thus, it is a true statement.
Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time. natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.
Thus the option Natural selection is correct.
Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.
Thus, the correct answer is - microevolution.
