Answer:
Her knee ligaments are weakened or injured so they can't stabilize the bones
Explanation:
Ligaments are dense connective tissues that serve to connect bones to each other. Ligaments are made by definite arrangement of collagen fibers in particular pattern. Weakening or injury to ligament makes the joints unstable. Since ligaments are not strong enough to hold the bones together, weakened or injured ligaments lead to bone dislocation. The woman with complaint of regular bone dislocation in her left knee must have weak or injured ligaments that can’t stabilize the bones.
Answer:
If the activity of osteclasts(which demineralize bone) exceeded osteoblast activity(production of new bone), then the bone's mineral content(and thus its mass) would decline, making it weaker.
Answer:
<h2>Primary spermatocytes and primary oocytes contain the diploid number of chromosomes.</h2>
Explanation:
Primary spermatocytes is derived from immature germ cells called spermatogonia by the process, mitosis.
While primary oocytes is derived from immature germ cells called oogonia by mitosis.
In both cases, they contain a diploid number of chromosomes(2N) since they have not yet matured into secondary sex cell. They are called as primary spermatocytes and primary oocytes respectively and they are with the diploid number of chromosome.
Answer:
1.50 cal
Explanation:
Given data:
Mass of water = 300 g
Initial temperature = 20 °C
Final temperature = 25 °C
Calories needed = ?
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Solution:
ΔT = T2 - T1
ΔT = 25 °C - 20°C
ΔT =
Q = m.c. ΔT
Q = 300 g . 4.18j/g. °C . 5°C
Q = 6270 J
J calories:
6270 / 4184 = 1.50 cal
