What are the physiological reactions to stress in the alarm stage
suter [353]

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

Which of the following contributes to the diversity of an ecosystem?
Luda [366]

Answer:

Increased keystone species

Explanation:

An organism is a keystone species when it contributes to the definition of a given ecosystem such that the absence of the keystone species in an ecosystem, the ecosystem will change dramatically or be gradually wiped out

The effect of the keystone on its environment is unevenly large when compared to its abundance relative among other organisms within the ecosystem

The keystone is therefore, a prime source of balance of nature, diversity and well-being of the ecosystem

Therefore, the option that contributes to the diversity of the ecosystem is;

Increased keystone species.

Please help, This is a science sheet for get my grade up.
finlep [7]

Answer:

Well The answer you choose was wrong I think because every living being that has cells need a Nulceus in their cells or the cells won’t work. Fungi have cells and Protista also have a nucleus since it has a cell or cells.

The answer here I would think would be (c) ”many could be found in fresh water”. Fungi don’t usually appear near seas or fresh sources which in this case is a pond and protistia do.
