Answer: B. Carbon Dioxide
Explanation:
Fossil fuel can release methane and other hydrocarbon. The reaction is processed between methane and oxygen in the air. When this reaction takes place the result is Carbon dioxide, water, and lots of energy (heat)

Answer: Option D
During isovolumetric contraction blood is flowing from the ventricles into the aorta and pulmonary arteries.
Explanation:
Isovolumetric contraction is an occurrence that happen in the systole where the ventricle contracts with no change in volume. Isovolumetric contraction causes the left ventricles pressure to rise above the atrial pressure which shut the mital valve and cause the first heart sound. When the pressure rises in the left ventricle, it contracts and pump blood to the aorta and pulmonary arteries. The ventricles continue to contract and blood continue to flow to the aorta and pulmonary arteries in the systole.
Answer:
Autocrine = Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Juxtacrine = Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.
Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.
Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.
Answer:
Both bacteria and blue algae are prokaryote organisms, meaning that they do not have a differentiated nucleus, and therefore they are more primitive. But blue algae are able to perform photosynthesis and so we can believe that the first forms of life on Earth date even further back than 3 and a half billion years ago.
