The sarcomere will have uncontrolled muscle contractions.
Troponin blocks myosin-binding sites in the tropomyosin of the actin. If the troponin is damages, the myosin-binding sites will be exposed and myosin heads (of the myosin fiber) will be able to form cross-bridges with the actin even when not required.
Explanation:
This means the sarcomere will contract even when not required or expected hence resulting in symptoms like muscle spasms. Usually, troponin molecules exposes the myosin-binding sites on the tropomyosin upon binding of Ca²⁺ ions. These Ca²⁺ are usually released by the sarcoplasmic reticulum upon impulse from the inverted nerve.

Answer:
Maria noticed a positive correlation
Explanation:
Correlation is used to measure the extend to which two or more variables are related.
It can be positive where one variable increases when the other increases.
Negative where the increase of one aspect decrease the other variable.
Lastly, no correlation means there is no relationship between the two variables hence a change in one will not affect the other.
In the case of maria, there is a positive correlation between having more energy the next day and her dancing.
Data have shown that men are 30% more likely to develop sepsis compared with women
Older adults become more susceptible to infections due to several factors
Answer:
The primary reason for the hip joint stability is the deep socket of the joint and strong capsular ligaments.
Explanation:
The primary reason for the hip joint stability is the deep socket of the joint and strong capsular ligaments.
It is a ball-and-socket multiaxial joint consisting of 2 structures.The femoral head and the acetabulum in particular. The labrum intensifies the acetabulum so that balance improves. A capsule which also improves stability is enveloping the ball and socket joint. There's also a negative pressure inside the hip joint, that leads to a hip joint's flexibility.
Answer: B. collar cells and amoebocytes
The collar cells have a funnel like collar and a flagellum. Collar cells whip their flagella to make water go through the sponge. Then the water brings nutrients and oxygen, while while also taking out waste and carbon dioxide.
Amoebocytes first deliver nutrients from choanocytes to the other cells, giving rise to eggs. Then they bring phagocytized sperm from choanocytes to eggs.
