A — is a protein that recognizes and responds to a signal
Norma-Jean [14]

Answer:

A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.

Explanation:

A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.

If there are two weights on the scale, one 1.5m from the fulcrum weighing 1.7 kg, and the second 1.2m from the fulcrum, what mus
kykrilka [37]

The fulcrum is the point in any mechanical device where the moment due to weights is zero.

(Weight 1 x distance 1) - (weight 2 x distance 2) = 0

(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0

weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m

= 2.1 Kg

How many food calories can a human burn up in an hour by exercising at this rate? (remember that only 20.0 % of the food energy
blsea [12.9K]

Human can produce a maximum mechanical power of 1/3 hp (horse-power).

Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)


So:

1 ph = 746 watt = 746 J/s

1/3 ph = 248.6 J/s

we're looking for the calories, so

1 joule = 0.239006 calories


So human produce a maximum mechanical power of:

248.6 J/s = 82.88 calories per second.


We're looking for the number of calories consumed in three hours, so:

82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).


The number of food calories is 895.2 food calories

d1i1m1o1n [39]

Answer:

These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.

In addition the empty tunnels serve as the routes for nutrients and oxygen supply  for the organ.

In summary the tunnels provided  a vascular structure to support the organ
