Answer:

C. Implement a biometric reader at the datacenter entrance and require passage through a mantrap.

Explanation:

The first step this installation should do is to limit access to only authorized persons. The safest way to do this is to use a biometric reader at the datacenter entrance, so in addition to just entering authorized persons, it would be possible to verify each individual's identity before allowing access to the server room and datacenter. The facility should also use a mantrap to separate safe areas from unsafe areas, so it can also limit access to the facility and decrease the chances of users tailgate behind other uses.

Use the normal ecg trace below to determine how many seconds the trace represents as well as the heart rate.

mezya [45]

Attached is the image of the concerned ECG reading.

In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.

<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of

ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.

How sexual reproduction increases genetic diversity in many species of plants and animals

Dafna11 [192]

Sexual reproduction is a process involving the fusion of two gametes to

Gametes are special reproductive cells produced by meiosis. It produces genetically dissimilar offspring. Offspring may inherit beneficial qualities from both parents and there is a greater genetic variation in the offspring, leading to species that are better adapted to changes in the environment.
