The given question is incomplete question as it lack essential part of question which is :

Ex: Write a hypothesis about the worms and lima bean plants. Be sure to answer the lab question.

Answer:

The correct answer would be : If plants grow in soil with worms, then growth of the lima bean plant will be greater due to worms helps in decomposing organic matter.

Explanation:

In this hypothesis the one species benefits other species in the same ecosystem they both exist. According to the hypothesis presence of the worms helps in the growth of the lima bean plants.

Dependent variable is a variable that depends on change in independent variable. Here the change in the presence of worms affects the growth of the bean plants so, the dependent variable is bean plant and the independent variable is presence of the worms.

Thus, the correct answer is : If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter

scoray [572]
<h2>Baroreceptors </h2>

Explanation:

  • Baroreceptors are splash type nerve endings in the walls of veins and the heart that are invigorated by without a doubt the degree of, and changes in, blood vessel pressure. They are amazingly rich in the mass of the bifurcation of the inner carotid corridors (carotid sinus) and in the mass of the aortic curve. The essential site of end of baroreceptor afferent strands is the NTS.  
  • The capacity of the baroreceptors is to keep up foundational circulatory strain at a moderately steady level, particularly during an adjustment in body position. Flawless baroreceptors are very viable in keeping quick changes in pulse from minute to minute or hour to hour, but since of their versatility to delayed changes of circulatory strain (> 2 or 3 days), the framework is unequipped for long term regulation of blood vessel pressure.
