The correct answer is a. vascular plants.
Vascular plants with larger sporophytes are gymnosperms, examples are conifers such as Cycas, Pinus and angiosperms, examples flowering plants are mango, sunflower. The dominant phase in these plants are diploid, independent sporophyte which produces two types of spores. Gametophyte is short lived and dependent on sporophyte.
aerobic, heterotrophic bacteria
anaerobic, autotrophic bacteria
anaerobic, heterotrophic bacteria
Answer:
Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.
Autotrophic can be called producers, and heterotrophic can be called consumers.
The question states that "did not use oxygen for respiration and were unable to make their own food"
Only one option satisfies the question:
anaerobic, heterotrophic bacteria
Answer:
Anaerobic, heterotrophic bacteria

Answer;
C6H12O6 + 6O2 6CO2 + 6H2O + ATP
Explanation;
- Mitochondria are tiny organelles inside cells that are involved in releasing energy from food, a process called cellular respiration.
-During cellular respiration nutrients such as glucose are broken down in the presence of oxygen to release energy in form of ATP and water together with carbon dioxide as by products. The energy released may be utilized by the cells to drive cellular processes, such as growth and movement.
Glycolysis, the initial stage of cellular respiration, offers several advantages essential for cells' energy production and survival. Two significant advantages are Efficiency and Substrate availability.
1. Efficiency: Glycolysis occurs in the cytoplasm and does not require oxygen, making it an anaerobic process suitable for cells in low-oxygen environments.
It rapidly converts glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.
2. Substrate availability: Glycolysis uses glucose, a simple sugar readily available from various sources like carbohydrates.
This flexibility allows cells to obtain energy from different nutrient molecules, ensuring a continuous supply of substrates for energy production even when other energy sources are limited or unavailable.
Glycolysis plays a fundamental role in sustaining cellular energy needs under diverse conditions.

Answer:
1) Conduction.
Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.
2) Radiation
The heat on the glass surface gets radiated into the chair which causes the chair to warm up.
3) Convection
The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.
1. Hot coffee warms the spoon through conduction,
2. a chair warms through radiation from the fireplace,
3. decorative lamp globs rise through convection.
1. Hot coffee is stirred with a spoon, the spoon gets hot due to conduction.
2. A chair is placed several feet from a fire in a fireplace. The fireplace has a glass screen. The side of the chair facing the fireplace gets warm because of radiation.
3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to convection.
