Answer:
unicellular life first
Explanation:
it arose billions of years ago while multicellular life forms around at least 600 million years ago
Answer:
Interactions between biotic and abiotic components regulate carbon dioxide and water levels.
Explanation:
Abiotic factors include temperature, water, humidity, etc; while biotic factors include all the forms of life. These factors interact in the ecosystem to maintain its homeostasis. For example, during the photosynthesis, plants use the energy of the sun water and carbon dioxide to produce food (carbohydrates) and this process converts carbon dioxide (CO2) to oxygen, which is critical for maintaining the homeostasis of the ecosystem.
1. Ask a question: He thought how traits passed from one generation to another.
2. Form a hypothesis: His hypothesis was "Each plat has two factors for a trait, one from each parent.
3. Test hypothesis: He grew pea plants to see what will happen.
4. Make and record observations: He discovered that one factor alone doesn't determine the expression of the trait in the pea plant.
<span>5. Conclusion: Traits in pea plants are inherited from the parent pea plants.</span>
Answer:
There is no diagram in this question but the question can still be answered without it.
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.
