This study is replicated in the Appalachian Mountains with similar results. Which of the following is true? The number of days w
Trava [24]

Answer:

There was no change in the number of days with poor flower availability

Explanation:

When replicating a study, the researcher develops the exact same study (experiment/treatment) in different places (experimental unit). In this case, as the researcher replicates the study in the Appalachian Mountains and gets similar results, that means that there was no change in the number of days with poor flower availability.

Drag each tile to the correct box.
levacccp [35]

Complete question:

Drag each tile to the correct box.

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.

  1. Interneurons relay the impulse to motor neurons in the spinal cord.
  2. She immediately moves her foot.
  3. The sensory neuron generates an impulse.
  4. Receptors in her toe receive stimuli.
  5. Motor neurons signal the leg muscles.

Answer:

4. Receptors in her toe receive stimuli

3. The sensory neuron generates an impulse.  

1. Interneurons relay the impulse to motor neurons in the spinal cord.

5. Motor neuron signal the leg muscles    

2. She immediately moves her foot.  

Explanation:

The reflex arc refers to an action mechanism that responds to different stimuli.  It is an involuntary reaction involving different nervous vias. The reflex arc is composed of receptors, afferent nervous fibers, efferent nervous fibers, and effectors.    

Receptors are located in nervous terminals and are widely distributed in the organism. Receptors are capable of receiving stimuli from different nature, and most of them are specialized in one kind of stimuli such as vision, audition, touch, among others. In the exposed example, these sensory receptors were located in the toe, and probably they were touch receptors.

When they receive the stimulus the sensory neuron transforms it into an excitatory nervous impulse that goes to the central nervous system along the afferent nerves. This stage is known as the <u>afferent via</u>, beginning with the environmental information received by sensory receptors, and ending in the arrival of the transcripted message to the central nervous system.

When the central nervous system receives the information, it processes it and sends an appropriate answer according to the stimulus. The message goes along the interneurons to the motor fibers, which are in charge of taking that answer to its destiny, the effectors. Effectors are usually muscles or glands, and they transform the received impulse into a motor answer that executes the reflex action. In the exposed example, the effector in the muscle. This stage is known as the <u>efferent via</u>, beginning in the central nervous system sending an answer impulse and ending in the effector (muscle) executing the answer.

Identify the substances that can readily pass through the inner mitochondrial membrane.
KIM [24]

Answer:

A,C E

Explanation:

The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated  folded inwards  to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.

The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix

These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy  for phosphorylation of ADP by  P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.

O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation  and ETC will nor occur.

CO2 must pass through because its accumulation will increase the acidity of the inner  mitochondria
