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
All biomolecules could be called carbon-based molecules.
The monomers of DNA are nucleotides.
Cell membranes are made, in part, from phospholipids.
The monomers of of starch are monosaccharides.
Explanation:
Biological macromolecules are giant carbon-based molecules. They are polymers made by complex condensation reactions linking them together.
These molecules are typically produced exclusively by living organisms and this is why they are called biological macromolecules.
They are usually classified as organic compounds for their linkage to living processes.
- It is correct that all biomolecules are carbon-based molecules. They are primarily made up of carbon, hydrogen and oxygen with some other elements.
- Deoxyribo-nuclei Acids are macromolecules that contains all information about the life of an organism. The DNA is located in the nucleus of cells and it is the genetic matter that controls life activities. The basic unit of DNA is the nucleotides.
- Cell membranes are structural component of cells that helps to regulate the movement of materials in and out of the cell. They are made up of phospholipids.
- Monomers of starch are monosaccharides. These are the simplest unit of starch that cannot be further hydrolyzed. They are usually called simple sugars. Examples are glucose and fructose.

Its B.cell wall
ribosomes are used to synthesis proteins and other components required for cells
endoplamsic reticulum is where the ribosomes are its a structure that helps to prepare the components and to bring them to the golgi body
the cell wall is only present in plants (cellulose) and fungi (chitin) and it helps plants to regulate their water intake physically
the cytoplasmis present in all cells as the medium which organelles are suspended in and in contact with
