svp [43]

<span>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.</span>

Explain the process by which Amoeba takes its food from the outside to inside the body

Dovator [93]

Explanation:

Feeding And Digestion In Amoeba

Initially, it pushes out its pseudopodia so that it can encircle the food. After this, it engulfs the food, thus forming a bag-like structure called food vacuole. The process is known as “phagocytosis”. ... Well, the excess food gets stored in the form of glycogen as well as lipids.

For a cell to maintain the appropriate balance of materials inside and outside of the cell, materials must be able to move in an

Mnenie [13.5K]

The answer is; permeability

This is the property of a material to allow fluids to pass through them without being changed physically or chemically. The membrane of the cell is referred to as semi-permeable because it allows only particular fluid through it depending on the pore size of the cell membrane. Particles that are larger in size can only be taken up by active transport such as by endocytosis.

Propose a question that a scientist might ask about the variety of organisms found around deep sea vents.

Svetlanka [38]

The answer is do all of these organisms use chemosynthesis.

Chemosynthesis is a process in which some bacteria produce sugar, similarly to photosynthetic process. But, while in photosynthesis the energy of Sunlight is used to convert carbon dioxide and water into sugar and oxygen, in chemosynthesis, carbon dioxide, oxygen, and hydrogen sulfide are used to produce sugar, along to water and sulfur. This process is preferable when there is no light and the environment is rich in sulfide or methane, such in deep sea vents.
Thus, to asses the variety of organisms found around deep sea vents, it should be researched if all organisms use chemosynthesis, or maybe some other process.
