Answer:D. convergent evolution

Explanation:

Cacti or cactuses are member of the plant family and are often referred to as spiny plants that are usually found in the desserts.

Evolution - In biology, is described the ascent or descent in the characteristics of a species over a series of generations

and natural selection favors its modification.

When two species populations evolve to become more similar to each other we say say they have a convergence evolution.

Hint: Evolution of analogous structures is always an example of convergent evolution.

Gwar [14]
Answer:
igneous rock CAN become sedimentary rock through a process called ROCK CYCLE.
Explanation:
Rocks can be defined as solid structures of minerals that are formed naturally over a period of time. They are grouped into three main types which includes the following:
- igneous rock
- sedimentary rocks and
- metamorphic rocks.
Rocks are capable of transforming from one type to another through a process known as rock cycle. There are two forces that brings about this process which includes:
- The internal force : this is the Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust.
- The external force: this is the the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.
Molten magma cools to form either extrusive igneous rock or intrusive igneous rock. With time they undergo weathering, eroded, transported, and then deposited as sediments which are being compressed and cemented into SEDIMENTARY ROCKS. Again through the above mentioned forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into METAMORPHIC ROCK.
Therefore the material in this sedimentary rock found in Rhombus planet used to be in igneous rock deep in Rhombus's interior due to continuous rock cycling on the planet. I hope this helps

xenn [34]

Answer:

The primary "food"  produced by  photosynthesis is a  6-carbon sugar called glucose.

Explanation:

Through photosynthesis, plants use the sunlight to create a sugar called glucose. The plants use this energy to create other substances, such as starch and cellulose. This gives them the nutrients and vitamins they need to grow.

Hope this helps! :)
