Answer:

Multicellular

Explanation:

Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.

As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.

Does this make sense? Feel free to comment any other questions!! If this explanation helped you, please consider leaving me a good review and/or brainliest!! <3

Use of moist heat can control microbial growth in many circumstances, but heat-sensitive items and those susceptible to moisture
sattari [20]
<h2>Answer is option "b"</h2>

Explanation:

  • Non-ionizing radiation is radiation that has a lower frequency, or longer wavelength, in the EMR spectrum. These frequencies range from that of power lines, radios, and cell phones, up to visible light. Non-ionizing radiation is not powerful enough to break the chemical bonds in molecules. In general, it is not harmful to human health as radiation per se, but could be harmful in terms of the transfer of heat energy. An example of an emitter of non-ionizing radiation is a microwave oven.
  • Non-ionizing radiation is less harmful because the rays carry much less energy. Radio waves, light, and even heat are examples of non-ionizing radiation. For the most part, these kinds of radiation do not cause any damage. However, ultraviolet light is a kind of non-ionizing radiation that can be harmful - it can cause mutations in DNA
  • Non-ionizing radiation is limited to the lower energy range electromagnetic radiation, which is more commonly known as light. However, the light we can see with our eyes, visible light, is only a small section of the electromagnetic radiation spectrum as seen here
  • Hence the right answer is option "b"
