A. A forest fire caused by lightning, which destroys a habitat
One major factor that is influenced by the shape of the earth and its tilt is temperature. It varies across the earth due to differences in the way the sun rays ‘hit’ different parts of the earth. This causes some regions to be colder and some warmer than others. This, therefore, causes terrestrial organisms in regions to vary due to their adaptation to their respective environments. Warmer regions usually have higher biodiversity than colder regions.
Answer:
They move from high concerntartion to low concertration
Explanation:
the diagram is not provided but am guessing there were bigger circles which could not pass through, which shows that the membrane was selectively permeable to smaller salt molecules. The movement across the membrane did not require energy.
Answer:
- 1/2 = 50% de la progenie será roja heterocigota, Rr
- 1/2 = 50% de la progenie será blanca homocigota recesiva, rr.
Explanation:
- El gen que codifica para el color de flor es dialélico
- El alelo R es dominante y expresa color rojo en homocigosis y heterocigosis.
- El alelo r es recesivo y expresa el color blanco en homocigosis.
Cruza: flores rojas heterocigotas con flores blancas
Parentales) Rr x rr

F1) 2/4 = 1/2 = 50% de la progenie será roja heterocigota, Rr
2/4 = 1/2 = 50% de la progenie será blanca, rr.
