An ecosystem<span> is a complete community of living organisms and the nonliving materials of their surroundings. Thus, its components include plants, animals, and microorganisms; soil, rocks, and minerals; as well as surrounding water sources and the local atmosphere. The size of </span>ecosystems<span> varies tremendously

Answer:
Her muscles are going through a stage of anaerobic respiration called Lactic Acid Fermentation and are producing lactic acid due to the fact that there aren't enough oxygen molecules present. This is causing there to be much less ATP produced but at a quicker rate. Her soreness is due to the building up of lactic acid in her muscles.
Explanation:
Cell respiration has two categories, anaerobic and aerobic. Anaerobic respiration happens when there is no or not enough oxygen present to go through Aerobic respiration. When you're doing high energy activities (such as running), your body doesn't have enough oxygen to go through the full aerobic respiration process and resorts to anaerobic respiration which, for animals, ends with Lactic Acid Fermentation. Doing this produces quick energy with the downside of also producing lactic acid which causes soreness in muscles.
Answer:
b. 8P+ , 10no , 8e-
Explanation:
An isotope is a form of a chemical element whose atomic nucleus of an element contains a specific number of neutrons and protons. For example, the nucleus of a carbon atom contains 6 neutrons(no) and 6 protons(P+) and similarly in the nucleus of oxygen contains 8 neutrons and 8 protons . The number of neutron can varies in the nucleus of that element. Variation in neutrons form isotopes of the element. In nature, oxygen has three stable isotopes, ¹⁶O, ¹⁷O, and ¹⁸O, but ¹⁶O most abundant. The ¹⁸O isotope of oxygen contains 8 protons(P+), 8 electrons(e-) and 10 neutrons(no) instead of normal 8 neutrons.
Answer:
membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)
Explanation:
Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane. These proteins account for different cellular functions. Some functions of membrane proteins include:
- Cell structure (attachment to the extracellular matrix and/or the cytoskeleton)
- Transport of nutrients and waste products
- Intercellular interaction between cells.
- Signaling transduction functions
- Cell recognition (e.g., during innate immune responses)
