The Earth's atmosphere would have little or no oxygen. A by-product of photosynthesis is oxygen. Photosynthesis is the process by which green plants use energy from the sun to make their own food in the leaves. The process uses sun light, water and carbon dioxide to yield oxygen and simple sugars. The simple sugars are stored in form of starch for future use by the plants, while oxygen is either used for cellular respiration or released to the atmosphere. The process of photosynthesis adds oxygen to the atmosphere and uses carbon dioxide from the atmosphere.
Answer:
C. The cells in these two areas have different functions.
Explanation:
The plant tissues are classified into three major systems: vascular, epidermic, and root systems. The vascular system is formed by tissues referred to as xylem and phloem. The epidermis is composed of superficial tissues that cover plant organs (i.e., leaves, stem, roots, etc). Finally, the root system is formed by tissues whose function is to supply to other plant tissues and store nutrients. Moreover, the plant tissues are also classified into meristematic and permanent tissues. In this case, it is reasonable to suppose that structurally different plant cells that are located at different areas of the plant will have distinct functions.
Some other secondary consumers are carnivores and others are omnivores because they also eat both plants and meat. For example Human, human are secondary consumers, and human eat both plants and meat. There are also other animals that are considered as omnivores.
Answer:
Muscle fatigue is often reported by patients with Marfan syndrome although myopathy is not classically considered a component of Marfan syndrome [1, 2, 4, 6, 7]. In addition to apparent muscle underdevelopment, some patients report myalgia or cramps suggesting skeletal muscle involvement.
