Answer:
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.
Explanation:
Electrons in an atom's outermost shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons, play a crucial role in determining the chemical reactivity of the atom.
What is an electron?The chemical reactivity of an atom depends on its ability to gain or lose electrons, which is determined by the number of valence electrons in its outermost shell. The valence electrons are the ones that are involved in chemical bonding, which is the process by which atoms combine to form molecules. Atoms with incomplete valence shells tend to be more reactive because they have a strong tendency to gain or lose electrons to achieve a stable configuration. A stable configuration is achieved when an atom's outermost shell is completely filled with electrons.
Hence, Electrons in an outer shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons,

What are potential impacts of using plastic digesting wax worms
Answer:
Wax worms, the larvae forms of moths such as Lesser wax moth (Achroia grisella), Greater wax moth (Galleria mellonella), and Indian meal moth (Plodia interpunctella), were recently discovered to be plastic-eaters. They are called wax worms because they are known to ingest beeswax. It was found that beeswax and polyethylene, that is present in plastic bags, plastic bottles, etc. have the same chemical composition.

What type of energy transformation takes place during cellular respiration? Use complete sentences to explain how energy is conserved during cellular respiration.
Answer: Chemical Energy
Explanation: Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism
Answer:
In this exercise, we will have to explain the transformation of energy in cellular respiration, as:
The type of energy transformation takes is chemical energy and the energy is conserved because The ATP molecule stores energy from cellular respiration and photosynthesis for immediate consumption.
Recalling how cellular respiration works we have:
Cellular respiration is a process by which organisms obtain energy to perform the most diverse activities. Cellular respiration occurs in mitochondria, in the presence of oxygen, and is divided into three steps: glycolysis, the citric acid cycle (or Krebs cycle), and oxidative phosphorylation.
How is energy stored in ATP?
Energy is stored in the bonds between phosphates. The molecule acts as a cellular currency, that is, it is a convenient form of energy transformation. The ATP molecule stores energy from cellular respiration and photosynthesis for immediate consumption.

The plant tissue that is pointed out by the lines in the enlarged diagram is ground tissue. Therefore, option B is correct.
What are ground tissues?Ground tissues are one of the three types of plant tissues. The other two tissues are dermal and vascular tissues. Ground tissues are responsible for most of the metabolic functions of the plant, including photosynthesis, storage, and support.
Ground tissues are composed of several different types of cells: parenchyma, collenchyma, and sclerenchyma. Parenchyma cells are the most common type of ground tissue cells. They are responsible for photosynthesis, storage, and gas exchange.
Collenchyma cells provide support to growing parts of the plant. Sclerenchyma cells provide structural support to mature parts of the plant. Thus, option B is correct.
