Abiologist counts the number of zebras in a population each year, and notices an increase in the zebra population. which describes the biologist’s actions? graphing inference observation interacting

Observation.

Explanation: The process of observing something in order to get information about it.

The change in the number of species an be observed by counting the number of zebras present in the population every year.

This can be observed only when the previous data is compared with the recent data.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
