<u>Answer</u>:
A) Determine the average number of times during a week in May that a group of bees visits flowers.
<u>Explanation</u>:
These observations may be mostly qualitative in nature at the real or exploratory stage of a study, but trials are usually done to show them in the form of quantitative data at some later stage. It is important that experimental information must be accumulated and arranged in a sequential fashion and in a form which can be understood by all: ideas may be more easily extracted, and results will be more easily drawn from data which have been arranged into a coherent pattern.
Answer:
C
Explanation:
Bulls are a more extreme version of a cow. A cow is like a mother who cares for her children while a bull is like a rowdy person who does weird and unpredictable things at times. That's why when people hear the word wild cow, they don't usually get frightened but when they hear the word wild bull, they kind of get afraid.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Answer:
3) Temperature
4) gill covering opening and closing per minute
5)as temperature rises, the rate of gill covering opening and closing per minute increase until the temperature reaches 27℃ where the rate decreases
Explanation:
4) you can adjust and control the temperature in an experiment
5) you can't control the gill opening and closing rate
Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
