Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
Answer;
-Cell
Explanation;
-The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Cells make up the smallest level of a living organism such as human beings and other living things.
-The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life. Some organisms, such as bacteria or yeast, are unicellular; consisting only of a single cell, while others, for instance, mammalians, are multicellular.
D. Bacteria because “bacteria” is actually a domain itself
Answer:
The study of living things.
Explanation:
Biology is known as natural science which helps to study the life of living things along with some characters such as development in characters, evolution in species, chemical processes inside the body, physical body structure, and molecular interaction between the ions.
Living species such as animals, plants are known as an open system that has the ability to survive by lowering entropy and transforming the energy to sustain stable homeostasis. Biology helps us to identify the basic unit of life which is known as cell and for creation and extinction of living organisms.
