Biodiversity is the different life forms and animals which exist on Earth. The biosphere is where all those animals live. hopefully, this helps
This question has choices namely:
preload
afterload
contractility
cardiac reserve
The correct answer is preload. Preload is the filling capacity of the heart and it corresponds to the volume of the blood that fills the ventricles during a cycle. In this case, the left ventricle needs to accommodate the increased volume from the right heat therefore increasing the filling capacity therefore the preload.
Afterload is the pressure that the heart needs to overcome to pump the blood. In the right ventricle, the pressure is the pulmonary arteries wherein the right ventricle needs to contract and generate a pressure greater than the pulmonary arteries for the blood to move out the ventricle. Similarly, in the left ventricle, the source of pressure is the aorta and the left ventricle needs to contract and generate a pressure greater than the aorta and the systemic circulation for the blood to move out of the ventricle.
Contractility is the force of contraction of each ventricle in one cycle.
Answer:
aerobic respiration uses oxygen and the steps are: 1. glycolysis 2. Krebs cycle 3. oxidative phosphorylation
anaerobic respiration does not use oxygen and the steps are: 1. glycolysis 2. alcohol fermentation

Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.
