During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product. Which is then needed for cellular respiration.
Answer:
When lichens and misses died off, they are usually replaced by bigger plants because they have made the place suitable for the growth of larger plants. The dead parts of lichen and misses decompose and turn into small particles of soil, this allow other plant species to grow in this location.
<h2>Capillary Smooth Muscle Contraction</h2>
Explanation:
- Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
- Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
- Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
- All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction
The answer to this question is true
C) DNA is made of 4 types of nucleotides
Not all organisms have 46 chromosomes (23 homologous pairs). Not all organisms have nuclei (e.g. bacteria do not have nucleus)
