Calculate the estimated density of the football. Use the formula
D = m/V
where D is the density, m is the mass, and V is the volume. Record your calculations in Table B of your Student Guide.
Given that the density of water is 1.0 g/cm3, make a prediction about whether the inflated football will float in water. Record your prediction in Table B.
The mass-to-volume ratio of an object determines its density.
• The tennis ball's density, D = 0.37gcm 3, makes it float in water.
• Because the golf ball has a density of D = 1.18gcm 3, it would sink.
Since the mass and volume (or radius) of the balls are not specified, the inquiry is not complete.
I'll therefore provide a broad explanation.
Tennis sphere
Assume the tennis ball has the following mass:
m = 56g
The radius is also:
T = 3.3cm
The ball's volume would be:
V = 4/3πr³
We thus have:
V = 4/3 x 22 x 3.33
V = 150.59
The ball's density is:
D = 772
We thus have:
D = 56/150.59
D = 0.37gcm 3
According to the estimates above,The tennis ball will float in water, according to the equations above, as 0.37gcm3 is less dense than 1gcm-3 of water.
Golf sphere
Assume:
m = 47g
r = 2.12cm
There is a volume:
V = 4/3πr³
We thus have:
V = 4/3 x 22 x 2.123
V = 39.93
The density is thus:
D = m/v
D = 47/39.93
D= 1.18gcm^-3
The tennis ball will sink in water with a density of -3 because 1.18gcm is more than 1gcm-3, according to the calculations above.

The sensation is the initial activation of the receptors, whereas perception is the process of organizing and interpreting the information in the brain.
Our nervous system is responsible for detecting stimuli and producing a response. There are generally five senses all of which have receptors that can sense environmental stimuli. When these receptors sense any information, sensation occurs. These sensations are sent to the brain in the form of electrical impulses, often called action potentials, to produce a perception. The process of converting the energy of stimulus into action potentials is called transduction. It is the first step toward perception.
Perception is the process that processes the sensations and understands the information. Perception then produces the final view of any sensation. For example, sensation produces the effect of various external stimuli like that of smoking. Perception helps us to recognize the smell of the smoke.

Be. This means that the glycolytic pathway predominates at this stage of pregnancy. It has been shown that later in development, the citric acid cycle becomes more dominant and embryos are much more susceptible to reduced oxygen tension.

Tropomyosin must change conformation, uncovering the myosin-binding site on an actin molecule and allowing cross-bridge formation. This can only happen in the presence of calcium, which is kept at extremely low concentrations in the sarcoplasm.
In order to reveal the myosin-binding site on an actin molecule and allow the development of a cross-bridge, tropomyosin must modify its conformation. Only in the presence of calcium, which is maintained in the sarcoplasm at incredibly low amounts, is this possible.
According to the sliding filament theory, muscle proteins slide past one another to produce movement during muscular contractions.
The sliding filament theory postulates that during muscle contraction, the actin (thin filaments) and myosin (thick filaments) of muscle fibers glide past each other while remaining at essentially constant lengths.
The myosin binding sites at the Actin filament are covered with the tropomyosin molecules which undergo conformational changes due to the attachment of the troponin to the calcium ions released from the sarcoplasmic reticulum during contraction and thus contraction of muscles takes place.
