Which of the following organs removes nitrogenous waste from the body?

Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane is a barrier that surrounds the cell and separates its internal environment from the external environment.

A chlorine molecule contains the fewest covalent bonds among the options provided. It consists of two chlorine atoms bonded together by a single covalent bond. Compared with the other options, ammonia has three covalent bonds, methane has 4 while water has 2.

The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

3' TCGATCGCA 5'

This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.

Lysosomes are membrane-bound organelles that contain lysozymes that are responsible for breaking down waste materials and cellular debris through intracellular digestion. This process helps maintain cellular health and homeostasis by recycling and degrading cellular components.

Uracil is the nucleotide that is only found in RNA. The other nucleotides are found in both DNA and RNA

Rationale

Electrons are subatomic particles that have relatively little mass and are negligible when calculating atomic mass. The atomic number is usually the sum of protons and neutrons in the nucleus of the atom.

The vermiform appendix is a small, finger-like projection that extends from the cecum, which is the first part of the large intestine.

Rationale

Atoms are the smallest and most basic units of matter, and they can combine to form molecules. Cells are the basic units of life, and they are made of molecules. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue or nerve tissue. Organs are collections of tissues that form a larger structure.
