Explanation:
Energy always flows from the sun, to the producer, to the primary consumer, to the secondary consumer, to the tertiary consumer, and so on. Algae has to come after the sun, because it's a producer.
Answer:
Answer:
Receiving the same amount of light intensity and water. Being grown in the same type of soil ensures that the above listed constant variable is maintained to ensure that any changes to rate of plant growth is solely due to changes in pH level.
Explanation:
The variable that u are testing Is change in pH level. Hence, to ensure results are reliable, u need to hold the other variables constant.
To increase the validity of this experiment, the researchers should replicate the experiment under different conditions or with a larger sample size. Further, running additional experiments with watering solutions having different pH levels could help in understanding the optimal pH for radish growth.
The activity that might aid in increasing the validity of this experiment on whether the pH of water affects the growth of radish plants is the replication of the experiment, preferably under different conditions or with a greater sample size. More experimental groups with varying pH levels may also make the results more valid and reliable. This means, instead of just having a group with a pH of 3.0 and another with a pH of 7.0, the researchers could consider using watering solutions with a pH of 4.0, 5.0, 6.0, and so on. This would help in pinpointing an optimal pH for the growth of radish plants and make the results of the study stronger.

The type of epithelium that contains two or more layers of epithelial cells is called stratified epithelium...
Explanation:
The type of epithelium that contains two or more layers of epithelial cells is called stratified epithelium.
Stratified epithelium is a type of tissue that consists of multiple layers of epithelial cells. These cells are stacked on top of each other, with the bottommost layer in direct contact with the underlying connective tissue. The cells in the basal layer are usually cuboidal or columnar in shape, while the cells in the outer layers can be squamous, cuboidal, or columnar, depending on the specific type of stratified epithelium.
It considered that all terrestrial plant species that exist today have evolved from Rhyniophyta (a type of spore plants, compiled by the most primitive forms of vascular). Now terrestrial plants presents by the Moss family, psilotaceae, lycopsids, class of the Horsetail, fern, gymnosperms and flowering plants. Based on the cladogram, It assumed that the ancestors of all existing plants are algae, particularly green.
