Answer:
If you have type B blood, you should only receive types B or O blood.
Explanation:
Answer:
Submerge a leaf in boiling water for one minute. This kills the leaf as it destroys membranes, making it easier to extract chlorophyll.
Answer is Outer ..inner.
The outer ear is
composed of the earlobe (pinna) and ear canal. The earlobe
collects sound (hence its characteristic
shape) and directed it via the rea canal
where it hits and vibrates the eardrum. The middle ear amplifies the sound and transmits it to the inner ear ( comprised of
the bony labyrinth, a hollow cavity in the temporal bone of the skull with a
system of passages) that has mechanoreceptors that convert the mechanical action of the sound to a nerve impulse.
Answer:
somatic motor neuron hyperexcitability; inhibition
The neuronal circuitry to skeletal muscles involves neurons that stimulate contractions and those that inhibit contractions. The muscle spindles and Golgi tendon organs are involved in maintaining the proper muscle tonus (resting muscle tension); they work by signaling the CNS. Since tetanus involves SOMATIC MOTOR NEURON HYPEREXCITABILITY, the neurons involved in muscle contraction INHIBITION are affected.
Explanation:
Tetanus is a infection that is caused by a bacteria called Clostridium tetani. It occurs when open wounds in the body are not properly treated and they get infected. This wound can be caused by stepping on a nail or sharp object like broken bottle.
When tetanus enters an open wound present on the body, it attacks the neurons in the body, specifically the somatic motor neurons. Tetanus hinders the release of neurotransmitters and blocks the inhibitory properties of the muscles. These causes the muscles of the body to contract unhindered and uncontrollably resulting in spasms. This can also be referred to as neuronal hyperexcitabilty.
The coloration of the beetles most likely remains constant, despite differential predation, when it is strictly due to ENVIRONMENTAL factors. Phenotypic traits can be influenced by genes or the environment.
The expression of a given characteristic (i.e., a phenotypic trait) in an individual may be associated with genetic and environmental factors, as well as with the interaction between genetic and environmental factors.
Different types of environmental inputs (e.g., diet, temperature range, oxygen, humidity, light, etc) can influence a given phenotype.
A heritability value near zero (0) indicates that almost all of the phenotypic variability for a given trait is caused by environmental factors.
