Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
Answer:
Animals release carbon dioxide into the air, and plants take it in.
Explanation:
The existence of plants and animals on the planet is important in maintaining life. Animals release carbon dioxide as waste through the respiratory system. The carbon dioxide that is released is then taken in by plants, which they use to produce their own food through a process called photosynthesis. The by product of that process is oxygen which is released in the atmosphere and animals take it in.
