8 0

Answer:

The correct answer will be option- D.

Explanation:

The somatic nervous system is divided into two divisions: the afferent neurons (sensory) which bring signals to the CNS and the efferent neurons (motor) which brings the signals to the muscle at the neuromuscular junction.

The motor neurons bring the signals in the form of the action potential which is sent to the muscle through motor wend plate which triggers a response in the muscle cells in response to the stimuli.

Thus, option- D is the correct answer.

An object has a kinetic energy of 32 J and a mass of 36 kg, how fast is the object moving?
marin [14]

Answer:

1.33 m/s

Explanation:

The formula for Kinetic Energy is given as:

K.E=\frac{1}{2} mv^{2} \\

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.

Re-arranging the above equation and isolating v, we get

2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}

Putting values in this equation, we get:

v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\  v=1.33

Thus, the object is moving with a velocity of 1.33 m/s

You disrupt all hydrogen bonds in a protein. what level of structure will be preserved? primary structure secondary structure te
arlik [135]

The protein structures can be classified into four levels, namely the primary structure, secondary structure, tertiary structure, and quaternary structure. The primary structure is the simplest  of all the structures. When all the hydrogen bonds are disrupted, the secondary, tertiary and the quaternary structures gets disrupted, which leads the protein to the most simplest structural form, that is the primary structure. In this structure, the a carbon atom is bonded to hydrogen atom, carboxyl group, amino group, and an 'R' group.

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).  

The inference procedure uses the information collected from the sample in order to obtain one conclusion.  Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
