Answer: The answer would be a stimulus this would be a stimulus because it is what causes the surroundings in an organism to change such as in its actions or behavior. I hope this helped you. Have a great night and god bless you :>
The genetic material inherited in an organelle, such as a mitochondrion or a chloroplast, exhibits Extranuclear inheritance.
When DNA in cytoplasmic organelles is handed on to offspring, extranuclear inheritance occurs. Cytoplasm can be found in both sperm and ovum cells in humans. Most of the extranuclear DNA formed when the sperm and ovum combine belongs to the mother. The organelles in the fertilized cell expand and divide as the fertilized egg grows. As a result, each new cell receives mtDNA, which likewise divides and is passed on. As a result, each child inherits mtDNA from the mother. The identical procedure takes place in creatures with cells that contain chloroplasts.
Nuclear DNA differs greatly from extranuclear inheritance in several ways.
- Chloroplasts and mitochondria both store several copies of DNA. Additionally, the cytoplasm of every cell contains a number of each organelle, occasionally thousands.
- In a cell's cytoplasm, chloroplasts and mitochondria are dispersed at random. There is a random distribution of amount in both daughter cells after cell division, whether it be through mitosis or meiosis.

Answer:
Genotype ( genetic appearance )
Explanation:
When some individuals of a population become isolated from the original population then the two groups are also not able to reproduce together due to difference in genotype, So variations and mutations which causes change in genotype that occur in one group are not necessarily found in the other group which leads to speciation. The longer the groups are isolated, the more different they are they eventually become different species called speciation. When some individuals of a specie remain isolated from the rest of the members due to any type of barrier ( physical or geological) in between the individuals of both the original species and currently isolated individuals so due to mutation the genotype of these individual changes and leads to speciation .
A protein is a polymer of amino acids. When amino acids are joined by dehydration synthesis (a process that removes water to form a chemical bond), they form peptide bonds. There are three main components of an amino acid, the amino group, the side chain, and the carboxylic acid group.
Answer:
White
Immune
Explanation:
White blood cells, also called leukocytes, are one of the cells that are involved in the body's immune system. They protect the body against various infections diseases and other invaders. Leukocytes are produced in the bone marrow (hematopoietic stem cells). They are not the only cells that are important for the defense of the body but are important.
