Which abiotic factor most likely controls where the plants live in this environment ?
Oxygen levels for aquatic animals
Oxygen from the air and oxygen produced by aquatic plants dissolves in water. Without this, aquatic animals would suffocate and die. Healthy lakes and rivers have high levels of oxygen, and polluted waters often have low levels of oxygen. This pollution means that only certain species can survive there such as sludgeworms. These are bioindicator species because their presence or absence informs us about the condition of the habitat.
Carbon dioxide levels for plants
Carbon dioxide is a reactant in photosynthesis which means plants need it to survive. Areas with higher levels of carbon dioxide are more likely to have healthy plants growing. Farmers often release carbon dioxide within their greenhouses to maximise their crop yield. Woodlands often have higher carbon dioxide levels than open grassland, so many plants living in open areas have evolved mechanisms to overcome a shortage of carbon dioxide.
Answer:
all 20
Explanation:
It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.
Answer:
The process of reuptake occurs when the sending neuron normally reabsorbs excess neurotransmitter molecules.
Explanation:
The process of reuptake takes place when a cell that initially produced and emitted a particular substance reabsorbs it again. Serotonin is one of the secretions affected by this process since it can be reabsorbed if it sticks to receptors located in the original nerve where it was produced to be then released once again.
