Answer:
sample 1 because it's mostly made up of organic matter to help plant growth
Explanation:
Answer:
Allele
Explanation:
A gene is a stretch of DNA that code for a specific protein. A gene can exist as two or more alternative forms. These alternative forms of a gene are called as alleles. The alleles are responsible for presence of variants of a particular genetic trait.
For example: The gene for plant height has two possible forms, i.e. two alleles. These are symbolized as "T" and "t". The allele "T" impart tallness while allele "t" imparts dwarfism to the plants.
1) Aerobic Respiration 2) Photosynthesis
Aero means Air, or in this case Oxygen, so Aerobic Respiration needs air, Photosynthesis uses Carbon Dioxide, Water, and sunlight to create Oxygen and sugars
I believe the answer is B
Explanation: The factors that DO affect photosynthesis are light intensity, temperature, and carbon dioxide concentration.
So we can automatically mark out A, C and D
Eukaryotic cells are more complex than prokaryotes
