The biodiversity in the marine reef ecosystem of the Great Barrier reef in Australia, Queensland has declined due to the increase of crown of thorns star fish. The increase of the starfish is caused by run off during the monsoon season via by fertilizers from agriculture.  As a result, the overall population of corals has declined by 25% from the starfish in the last 30 years. The decline of corals will decline the population of other species such as fish and will have a negative affect on other species.

A client in skeletal traction has a nursing diagnosis of Impaired Tissue Integrity: Related to puncture wound; pins.
VladimirAG [237]

Answer:

The client traction weights are resting on the floor.

Explanation:

The immediate action of the nurse should be to reapply the weights to give traction to the fracture. The health care provider must be notified that the weights were lying on the floor, and the client should be realigned in bed. The client's blood pressure is slightly elevated; this could be related to pain and muscle spasms resulting from lack of pressure to reduce the fracture. Oozing of clear fluid is normal, as is the capillary refill time.

Find the kinetic energy of a ball moving at 45 m/s with a mass of 0.18kg
mamaluj [8]

Answer:182.25 joules

Explanation:

Mass=0.18kg

Velocity=45m/s

Kinetic energy=(mass x(velocity)^2)➗2

Kinetic energy=(0.18 x 45^2) ➗ 2

Kinetic energy=(0.18x45x45) ➗ 2

Kinetic energy=364.5 ➗ 2

Kinetic energy=182.25

Kinetic energy=182.25 joules

Why does the rate of heart beat increases during exercise?
kherson [118]

During exercises, our muscles needed energy for contractions. The heart pumps more rapidly and more powerfully during this time for a few reasons.


First, more oxygen and nutrients like glucose can be transported to the heart. Muscle cells uses oxygen and glucose for aerobic respiration to generate energy.


Secondly, more carbon dioxide and waste can be transported away from the muscles. Waste products from aerobic respiration includes carbon dioxide or water etc. The faster the heart pumps, the faster the blood gets transported so more waste can be carried away.


Thirdly, lactic acid can be carried away too. When oxygen supply is not enough, the cells undergo anaerobic respiration to generate energy. This type of respiration does not require oxygen, but a waste product called lactic acid is produced. Lactic acid must be carried away from cells because they're harmful. Therefore, the faster the heart pumps, the more lactic acid gets carried away.


Last but not least, heat can be carried away too. Part of the energy generated is turned into heat. Therefore, in order to help us cool down, blood travels fast to carry heat away from the heat generating muscle cells.
