Answer:
The functions of the skeletal and muscular systems differ in that bones provide structure and support to the body, while muscles move the bones.
Explanation:
The skeletal and muscular systems have complementary functions, which is why they are sometimes referred to as the <u>musculoskeletal system</u>.
Bones are solid organs, made up of calcium, which are connected to each other through joints, which provide them with a certain range of mobility. The main functions of the bones are protection and body support.
Muscles are contractile organs that are attached to bones by tendons. The location and relationship of the muscle to the bones is what makes it possible for the bony skeleton to move. Muscle contraction and relaxation is what contributes to the different body movements.
The other options are not correct because:
- <em>The function of the bone is to support, and the function of the muscle is to produce movement.
</em>
- <em>Bones and muscles are not the ones that send the signals for body movement to occur.</em>
Slender stalk and the filament
Answer:
3.5 g
Explanation:
To solve this particular question, we will use the equation
R = h² * S, where
R, is the response to selection. This response to selection is the difference between the mean of the starting population and the mean of the progeny of the selected parents.
S, the selection differential, is the difference between the mean of the starting population and the mean of the selected parents
From the above explanation, we then have.
R = 5 g - 2 g = 3 g.
S = 6 g - 2 g = 4 g.
On Substituting the values into the equation, we have
3 g = h² * (4 g)
3 g = 4gh²
h² = 3g/4g
h² = 0.75.
If the selected plants are said to average 4 g, this then mean that S would be 2 g. If S is 2 g, using the earlier stated formula,
R = 0.75(2 g) = 1.5 g.
Therefore, the predicted average weight of strawberries from the progeny plants would have to be
2 g + 1.5 g = 3.5 g.
