Answer:

Cells in a large multicellular organism communicate with each other by chemical signals. These signals are passed from one cell to another. To receive and respond to a chemical signal, a cell must have a <u><em>receptor</em></u> for that chemical.

Explanation:

To generate a physiological response, all cells in the body have special proteins called receptors. These receptors are involved in detecting a chemical signal and generating a response. The receptors are specific for different kind of chemical signals. For example, a dopamine receptor will bind a dopamine molecule whereas an insulin receptor will be able to bind an insulin molecule. Apart from chemical signals, some cells might also respond to mechanical signals.

How do the respiratory and circulatory depend on each other for gas exchange?
Juli2301 [7.4K]

Answer:

Explanation:

Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will

carry oxygen which is transported around the body.

Looking at the chemical reaction provided here, propose a different method that could be used to measure amylase activity: Starc
Anna007 [38]

Answer:

Starch + H2O = maltose

This reaction gives the Starch and H2O as the reactants and Maltose as the product.

Amylase is an enzyme which helps in the digestion of Starch molecules and its activity can however be measured through careful monitoring of the disappearance of amylase substrate which is in this case, starch.

Answer:

The distance traveled by Joe in feet is 39,372 ft:

Explanation:

The conservation factor from km to Ft is 1 km = 3280.84 feet.

* In order to convert the value-form km to ft then we multiply the given value of the length by 3281.

*We are given that:

*Distance traveled by Joe = 12km

*Distance in feet = 12×3281

*Distance in feet = 39,372 ft

**Thus, the Distance traveled by Joe in feet is 39,372 ft.
