The groups of organisms containing a cell wall are Plantae, Fungi, and Eubacteria. The correct option is D. I, Ill, IV.
What is a cell wall?A cell is the outer covering of the cell, which provides protection and rigidity to the cell. It is made up of lipid and triglyceride or cellulose. The cell wall is presenting many cells, like plant cells, fungi, and bacteria cells.
The cell wall is made up of different substances in different animals. Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.
Thus, the correct option is D. I, Ill, IV.

4. Which of the following is a parasite?
(a) Mushroom
(b) Fungi
(c) stem
(c) Cuscuta
(d) haustoria
(d) Rhizobium
Answer:
C: Cuscuta is a parasite .
Explanation:
Mushrooms are a part of the fungi domain meaning that it is a decomposer. I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.

Energy in this ecosystem passes directly from the sun to.
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.

Age of fossilIt is a measure of how long a material has been fossilized.
Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.
