____ [38]2 years ago
8 0

Answer:

33.3

Explanation:

Normally there are 4000 to 11000 WBCs in a microliter of blood averaging almost 7500. While there are 150,000 to 350,000 platelets in a microliter blood of a normal person averaging almost 250,000. Thus the ratio can be as 250,000 :7500 resulting in 33.3. If a range is to be given, it ranges from 31.8 to 37.5 per microliter of blood.

Which of the following is true concerning cancer cells?
Iteru [2.4K]

Answer:

a.They evade the normal controls that trigger programmed cell death.

Explanation:

Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.

Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.

The amount of energy at trophic levels one and four in an ecosystem is indicated by the numbers.
nexus9112 [7]

Answer:

1100

Explanation:

There is 10% of total energy in each increasing trophic level.                    10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.

1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.

1,000 + 100 units of combined energy would be 1,100 units of energy.

Hope this helps!
