Explanation:
335 million years ago. The continents together were called Pangea(the supercontinent)
If a scientist is conducting an experiment about obesity and asks a group of people to stop eating saturated fat, that group of people is called the experimental group. Thus, the correct option is A.
<h3>
Define experimental group in scientific study?</h3>
A experimental group in scientific study is defined as the researcher compares at least two groups during an experiment, a control group and an experimental group.
Because they are both made up of people from the same population, they are identical in every way except for the independent variables.
The therapy is administered to the experimental group. The researcher willingly alters the independent variable's values to see how it impacts the people who are being studied. Several experimental groups are possible.

The stem has more things to transport that's why it has more vascular bundles. The roots only get water from the ground and moving nutrients from the soil to transfer it to the stem. Having more vascular bundles helps the stems to transfer things to leaves and other parts of the plants.
The correct answer is (4) Autotrophic organism.
Green plants make their own food by the process of photosynthesis using sunlight. Most of the autotrophs use carbon dioxide, sunlight and carbon dioxide to produce glucose that is used by the plants to obtain energy. Most of the oxygen comes from these organisms and decrease in the number of green plants can lead to several problems due to decrease in the amount of oxygen. Example: green plants, algae, and even some bacteria. This food and oxygen is produced by the action of autotrophic organisms
