Answer:
An atom consists of protons, electrons, and neutrons.
Explanation:
The atom of an element is its smallest indivisible particle that retains its chemical properties. Atom is the fundamental and basic unit of matter.
The structure of an atom is made up of a positively charged PROTON, a neutrally charged NEUTRON (both contained in the nucleus) and a negatively charged ELECTRON that surrounds the nucleus. These three particles are called sub-atomic particles. The arrangement and number of these sub-atomic particles determine the properties of the atom.
O-H bond is referred to as the most polar.
Explanation:
O-H bond is said to be most polar because the electronegativity is different. Electronegativity can be said as the atom's ability to attract electrons towards itself. Electronegativity of an atom increases when there is a movement on the periodic table from left to right.
When the electronegativity between the atoms are different then it is said to be a polar bond on the other case if the electronegativity between the atoms are same it is said to be non- polar bonds.
Conjugation is the direct transfer of DNA from one bacterium to another.
Bacteria can exchange genetic information through three different mechanisms; conjugation, transduction, and transformation. Bacterial conjugation involves the transfer of a plasmid from one bacterium to the other, through cell-to-cell contact. Bacterial transduction is performed through bacteriophages. Bacterial transformation refers to the process of moving genetic elements to various positions of the genome.

the breasts at puberty
Estrogen is a sex hormone and it is one of the most important hormones for women, together with progesterone. During
puberty, estrogen hormones are released in line with each monthly menstrual
cycle by the ovaries and it helps in the development and maintenance of
female characteristics in the human body such as breasts, pubic and armpit hair. Estrogen also regulate the menstrual cycle and reproductive system of women.
Balanced blood sugar helps keep our brain healthy, our energy levels stable and our mood balanced. However, when disrupted, our blood sugar can lead to increased sugar cravings, irritability, poor sleep, brain fog, anxiety, low energy and weight gain, and in the longer term, diabetes
