Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?a. They absorb carbohydrates through the soil.
b. They absorb dissolved carbohydrates via water.
c. They make carbohydrates through the process of photosynthesis.
d. They make carbohydrates through the process of cellular respiration.

Supernova:

In this stage, the star collapses and produces elements heavier than iron.

Planetary nebula:

In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core.

Neutron star:

In this stage, the star has reduced to an extremely dense core.

White dwarf:

In this stage, the star has reduced to a dense core.

Answer:

large=  supergiant, supernova, then a neutron star

small= giant, planetary nebula, white dwarf

Explanation:

star life cycle changes by these phases

The correct order of steps in an experiment would be:

• Identify the variables.
• Write out your hypothesis in an if/then format.
• Gather your materials.  
• Analyze the data.
• Write your conclusion.

What is an experiment?

An experiment is a term to refer to the process by which a hypothesis is supported/disproved. The experiments serve to explain the cause-and-effect relationship according to the results obtained.

Experimentation has some important steps that we must follow to demonstrate our ideas regarding a scientific manifestation, these steps are:

• Identify the variables: We must identify the factors that we can manipulate so that the result changes.
• Write our hypothesis: Establish a hypothetical result that we are going to demonstrate.
• Gather the materials: We must have all the materials and variables to be able to carry out our experiments.
• Analyze the data: When we do an experiment we must record everything we see and then analyze it to examine each step and the procedures performed.
• Write the conclusion: After analyzing the data obtained, we can write a conclusion about the experiment carried out and the result obtained.

Answer:

Transport materials such as fluid and propagation

Explanation:

Planta with vascular systems are called tracheophytes, this plant dominate the ecosystem in terrestrial habitat and were successful because of their tube like vascular tissues.

The vascular tissues are used in transporting of fluids such as minerals, photosynthate and are usually made up of cells that are long and narrow end that forms tubes. There are two different types of vascular tissues, called xylem and phloem.

This systems help transport nutrient required for plants growth and development to avoid plant loss and redundant growth.

Seed plants allows them for propagation and ensures continuity

Answer:

colonize land ecosystems.

Explanation:

Common characteristics supporting the idea that the first land plants were related to green algae include All of the above. Thus, option "D" is correct.

Which algae is responsible for main supply of oxygen in the atmosphere?

The Green algae are responsible for the main supply of oxygen in the atmosphere. There are tiny organisms called cyanobacteria (or blue-green algae) which photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.

The waste product of cyanobacteria is the oxygen of the atmosphere.

Thus, option "D" is correct.
