cloaca

Q: Which type of respiration helps organisms generate quick bursts of speed, as opposed to long steady movement? Read this paragraph and choose the correct option from the provided answers: Each type of muscle fiber has advantages and disadvantages, which reflect their differing biochemical pathways. Aerobic respiration in red muscles full of mitochondria, produces a great deal of ATP from far less glucose - but slowly, over a long time. Anaerobic respiration in white muscle cells full of carbohydrates, produces ATP rapidly for quick bursts of speed, but a predator who continues pursuit may eventually catch a white-muscled prey. Choices: - insertion respiration - anabolic respiration - digestion respiration - anaerobic respiration A:
(Answer)
anaerobic respiration

Ques: Q: What are scientists called who study the weather and give forecasts? Read this paragraph and choose the correct option from the provided answers: People often complain when the weather forecast is wrong. Weather forecasts today, however, are much more accurate than they were just 20 years ago. Scientists who study and forecast the weather are called meteorologists. How do they predict the weather?. Choices: - climatologists - geologists - botanists - meteorologists A:
Ans: meteorologists

Q: Animals that are endotherms or ectotherms are distinguished by the ability to maintain a constant what? Read this paragraph and choose the correct option from the provided answers: Endotherms and Ectotherms Animals can be divided into two groups: some maintain a constant body temperature in the face of differing environmental temperatures, while others have a body temperature that is the same as their environment and thus varies with the environment. Animals that do not control their body temperature are ectotherms. This group has been called cold-blooded, but the term may not apply to an animal in the desert with a very warm body temperature. In contrast to ectotherms, which rely on external temperatures to set their body temperatures, poikilotherms are animals with constantly varying internal temperatures. An animal that maintains a constant body temperature in the face of environmental changes is called a homeotherm. Endotherms are animals that rely on internal sources for body temperature but which can exhibit extremes in temperature. These animals are able to maintain a level of activity at cooler temperature, which an ectotherm cannot due to differing enzyme levels of activity. Choices: - step temperature - bearing temperature - Moving Tempature - body temperature A:
(A).
body temperature

Ques:Q: What is the term for a particle from outside the cell engulfing the cells membrane? Read this paragraph and choose the correct option from the provided answers: In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane. There are two main kinds of endocytosis: pinocytosis and phagocytosis. Choices: - metastasis - endometriosis - mitosis - endocytosis A:

Ans:endocytosis
