Answer;
D.Carbon-based macromolecules are found in all life forms.
Explanation;
-Most molecules that make up living things are based on carbon atoms. The structure of a carbon atom allows it to form up to four covalent bonds. It can bond to other carbons or to different atoms.
-All organisms are made of four types of carbon-based molecules; carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are molecules made of carbon, hydrogen, and oxygen. Sugars and starches are both types of carbohydrates. These carbohydrates can be broken down to produce energy in cells. Some carbohydrates are part of cell structure in plants.
-Lipids are molecules that include fats, oils, and cholesterol. Lipids are nonpolar, so they do not dissolve in water. Like carbohydrates, most lipids are made of carbon, oxygen, and hydrogen atoms. Some lipids are broken down and used as energy in cells.
-Proteins are the most varied of the carbon-based molecules in organisms. There are many different types of proteins. They are involved in many different body functions including movement, eyesight, and digestion.

Answer: True
Explanation:
Renin ( angiotensinogenase), is an aspartic protease protein which is secreted by kidney that participates in the body's renin – angiotensin – aldosterone network that mediates arterial vasoconstriction and extracellular fluid volume.
Renin is released by cells of the juxtaglomerular apparatus in response to the stimuli of decrease in arterial blood pressure and the degree of stretch of the arteriole wall.
Hence, the statement is true.
I would like to know who is teaching you this? Social studies IS a science. Sociology is a science that follows your everyday scientific method. Formation of opinions (hypothesis) testing it out, making those observations and interpreting the facts.
Art, however, doesn’t have the hypothesis process as much, so for the sake of answering your question, by process of elimination I would have to say B.
Primary succession is when there isn't any soil when a new community begins.
Secondary succession is when an event such as a fire destroys an area but leaves the soil.
Primary succession would transition to secondary succession by starting off without any soil. Overtime the community would begin to grow and then soil would appear and plants would start to grow. It would then change to Secondary succession whn an event destroys that area leaving just the soil behind.
