Answer:

1. 6.56 km/hr

2. 1.83 m/s

Explanation:

The average velocity/speed can be calculated using the formula;

Average speed/velocity = distance/time

According to the information provided in the question, distance = 12.5km, time = 1.9h

Average velocity in km/hr = 12.5/1.9

= 6.578

= 6.56km/hr

However, in order to calculate the average speed in m/s, we have to convert distance in km to m, and time in hour to seconds.

1km = 1000m

12.5km = 12.5 × 1000

= 12500m

1 hour = 3600seconds

1.9hours = 1.9 × 3600

= 6840seconds

Average velocity = 12500/6840

= 1.827

= 1.83m/s

Answer:

<em>The correct option is A. The Population will decline over time</em>

Explanation:

As the phytoplanktons won't receive enough sunlight, they will not be able to make enough food by photosynthesis. As a result, the phytoplanktons will start to die and they won't be able to reproduce abundantly like before. Hence, the population will decline.

Other options like option B are false because the population will not decrease their need for food. They will start to die due to lack of food and sunlight.

What energy carrier molecules are produced by glycolysis
blagie [28]

Answer:

"Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy"
