What else can I help you with?
Why does respiration occur at different rates in cells?
Different metabolic rates.
Do neurons have high metabolic rates?
yes
How do metabolic rates of ectotherms and endotherms compare?
Ectotherms have lower metabolic rates than endotherms because they rely on external sources of heat for regulating their body temperature, while endotherms generate heat internally. Endotherms have higher metabolic rates to maintain their body temperature within a narrow range, compared to ectotherms whose metabolic rates can vary more with environmental temperature.
Why do metabolic rates differ?
Most metabolic rates differ due to a number of reasons. Metabolism can change due to activity level, heredity age and food consumption.
What are the inherited factores that metabolic rates?
inherited factors cause obesity
Why are the rates of diffusion of nitrogen gas and carbon monoxide are almost identical at the same temperature?
The densities of these gases are virtually identical.
Why do periwinkles lower their metabolic rates?
Periwinkles lower their metabolic rates in response to environmental stress, such as high temperatures or low oxygen levels, to conserve energy and increase survival chances. This adaptive strategy allows them to endure adverse conditions until more favorable environmental conditions return.
What age metabolic rates tend to decline?
Metabolic rates generally start to decline around the age of 30. As we get older, muscle mass tends to decrease and fat mass tends to increase, which can contribute to a decrease in metabolic rate. Regular exercise and a balanced diet can help maintain metabolism as we age.
The rate at which wastes are produced by a cell partially depends on the cell's?
metabolic rate and function. Cells with higher metabolic rates and active functions tend to produce more waste compared to cells with lower metabolic rates and less activity. The efficiency of waste elimination processes within the cell also plays a role in determining the rate of waste production.
Where can one find information on Basal metabolic rates?
A basal metabolic rate (BMR) is the amount of energy expended by humans and animals daily while at rest. To find more information, contact your family doctor to determine your basal metabolic rate.
Which of the following abiotic factors has the greatest influences on the metabolic rates of plants and animals?
Temperature is the abiotic factor that has the greatest influence on the metabolic rates of plants and animals. Temperature affects the speed of biochemical reactions, enzyme activity, and overall metabolism in both plants and animals. Extreme temperatures can significantly impact the metabolic processes of organisms, leading to adaptations for thermal regulation.
Why do small animals have higher metabolic rates compared to larger animals?
Small animals have higher metabolic rates compared to larger animals because they have a higher surface area-to-volume ratio, which means they lose heat more quickly and need to generate more energy to maintain their body temperature.
