Answer:
The correct answer is option A: "the maintenance of homeostasis within the body system".
Explanation:
The pancreas secretes insulin and glucagon, hormones that work together for the maintenance of homeostasis within the body system. When the blood sugar level is low, the pancreas secretes glucagon to raise them. When the blood sugar level is high, the pancreas secretes insulin to lower them.
Answer;
-The microscope could be used to see if the specimen has functioning cells and a metabolism.
Explanation;
-Living organisms such as humans which are multicellular organisms and amoeba which are unicellular are similar in that they maintain homeostasis, contain functioning cells, have a metabolism, and are able to reproduce among other characteristics. All these and other characteristics may be observed using a microscope.
Answer:
Question:- where is the whale meat being sold in Japanese markets coming from?
Observation:- The availability of whale meat in Japanese markets exceds that expected from the reported legal captures of whales.
Hypothesis:- If whales are being illegally harvested, reported whale captures will be far lower than the number of captures predicted by genetic analyses of whale meat in markets.
Prediction:- Whales are being harvested illegally and their meat sold in markets in Japan.
Test:- Scientists subject whale meat to genetic analysis to determine its likely capture location and to estimate whale captures at that location.
Explanation:
Scientific method is a core problem solving approach in biology, chemistry and physics.
The scientific method has five basic steps:
1) Observation: Data you collect during an experiment
2) Question: the thing that you want to know. The question you want an answer to.
3) Hypothesis: this is a possible explanation that can be tested to see if it is likely correct or if we need to make a new hypothesis.
4) Prediction (based on the Hypothesis): this is an outcome we'd expect to see
5) Test: to perform an experiment on the data available.
