Biology

Levart [38]3 years ago

It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their stability to withstand the tension. This stretching can result in small micro-tears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers.

Answer:

Dystonia

Explanation:

Dystonia is a movement disorder in which a person's muscles contract uncontrollably. The contraction causes the affected body part to twist involuntarily, resulting in repetitive movements or abnormal postures.

Which synapse(s) are specifically responsible for the sensitization of the withdrawal response?
qaws [65]

The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.

The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.

By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.

Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.

Why does net productivity diminish with increasing trophic levels??
geniusboy [140]
Due to the bad trophic efficiency transfer, there is a loss in the consumption of most energy to cellular respiration at trophic levels. It also loses energy to heat, metabolism and other subsistence for biomass production. There is a higher energy loss when it is at higher trophic levels.

Compare and contrast the two cycles of matter
sertanlavr [38]

Answer:

The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms. 

They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition. 

Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.
