6. Interoceptors

b. special modality of stimulus

Answers

Answer:

a. general stimulus origin: Proprioceptors, Exteroreceptors, Interoceptors

b. special modality of stimulus:  Baroreceptors, Chemoreceptors Thermoreceptors

Explanation:

The sensory modality of stimulus refers to the aspect of a stimulus, and the sensation that is felt after a stimulus has had effect. Different sensory modalities include, temperature(thermoreceptors), light, chemicals(chemoreceptors), pressure(baroreceptors), and sound.

Stimulus origin is a classification system of receptors that indicates where a stimulus stems from. Exteroreceptors detect stimuli from the external environment and an example is the receptors found in the nasal cavity. Interoceptors are found in the internal organs and typically affect the smooth muscles of these organs. Proprioceptors are found in muscles, joints and tendons.

a researcher has 15 pure bred wild mice which were bron and all were females. they were all mated with a male called Bob.All the offspring were brown/ these were then crossed among themselves with the the following results 293 brown and 115 white. determine the color of bob

Answers

Answer:

1. Brown.

2. Brown colour is dominant.

3. 2.5 : 1

Explanation:

The colour of Bob is brown because the offspring produced from mating are also brown. The dominant colour in these mice are brown due to presence of this brown colour in all mice. We know that dominant traits always appear in the form and structure of an organisms and we see all mice have brown colour so we can say that the dominant colour is brown. The ratio of brown to white in the 'grandchildren' are 2.5 : 1 means more mice has brown colour as compared to white.

Squirrels eat acorns. Good acorn production happens when there are good growing conditions for the oak trees that make acorns. Often, there are many acorns produced one year but very few acorns the next year. What is the most likely impact on the squirrel population in years when fewer acorns are produced?

Nest size will increase.

Competition will increase.

Predation risks will increase.

Reproduction rates will increase.

Answers

Answer:

B competition will increase

Explanation:

this is because if there are less acorns then squirrels then they will all fight for the acorns and some will die to starvation. nest size won't increase because there isn't enough food for the squirrels already there. predation will decrease because there is less squirrels so that means less pray for the animals that eat the squirrels. then there is reproduction rates will increase. It is not that one because there are squirrels dying from starvation there aren't squirrels reproducing. that is why your answer is B.
