The three states of matter are solids, liquids, and gases. Sometimes, in extreme environments, there is plasma.
<u>Infrared</u> waves have a long wavelength and do not possess sufficient energy to kill bacterial cells, while <u>UV</u> waves have a short wavelength and can be used to sterilize a surface.
- When ultraviolet light, also known as ultraviolet germicidal irradiation, is released at its most effective wavelength of 253.7 nanometers (nm), it has the greatest ability to kill germs and render microbes inert (UVGI). When transmitted at wavelengths different than those recommended, germicidal efficacy declines.
- To efficiently deliver the appropriate amount of UV radiation for the desired application, high-quality UV sterilization lamps are crucial.
- By altering cell DNA, UV radiation sterilization efficiently renders bacteria inert.
- Because DNA is necessary for cell reproduction, damage to the DNA's structural integrity prevents cells from multiplying and causing disease.
- The cell absorbs the UV rays, resulting in the formation of pyrimidine dimers.
- Instead of bonding across the double helix, this causes two nearby thymine or cytosine bases to interact with one another.

<u>Answer:</u>
<em>D. It is the female part of the plant and contains the ovules, which house the main egg.
</em>
<u>Explanation:</u>
Pistil is the part of female reproductive system of the plants. Stigma, style and ovary together constitute a pistil. Ovary is the swollen base of the pistil that contains eggs or ovules to which the nuclei of the pollen grain fuse and form seed.
Stigma is the outer most part that captures the pollen grains and transfers it to the ovary through the style. Style is the elongated part that connects the stigma and the ovary.
<h2>Neural crest </h2>
Explanation:
The neural crest likely forms: neurons and glia of the peripheral nervous system
- The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
- In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
- The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
- Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
- Glia are also essential to nervous system function, but they work mostly by supporting the neurons
The set point is the normal, or target, value for something.
