Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
Answer:
To conclude, you cannot prove a hypothesis because you can never generalise the results to the whole population and foresee the results will always be the same in the future. You can however, reject the null hypothesis consistently, through statistical hypothesis testing so that the theory becomes highly likely to be true, but not proven.
Explanation:
Answer:
When nutritional protein is in brief supply, the frame tends to take protein from skeletal muscles to keep more important tissues and frame functions. As a result, lack of protein ends in muscle losing over time. ... Loss of muscle tissues is one of the first signs of inadequate protein intake.

There’s no answer choices but some characteristics of plants are that they are multicellular, eukaryotic and perform photosynthesis. Hope this helps. :)
The correct answer is - b. make their own food.
The plants are differing from most of the other organisms in that that they produce their own food. In order to produce their own food, the plants use the sunlight, carbon dioxide, water, and nutrients from the soil. They manage to perform a process called photosynthesis in which they manage to turn those things into sugars, thus create their own food. That makes the plants producers, which puts them on the bottom of the food chain, meaning they are the basis and most important part of the ecosystems in which they exist.
