Answer:
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.

Adenosine Triphosphate. Adenosine triphosphate, or ATP, is the primary source of energy in both plant and animal cells. ATP is a nucleotide that is the basis for all cell reactions, including the reactionary process of converting food molecules into energy.

Science and the method is the scientific process.
Science is the pursuit of knowledge and discovery from and to describe the unknown.
<span>Scientific models, paradigms and theories are used widely by most scientist as to serve possible predictions, testing hypotheses, providing explicit answers and even saving human lives. These models are the simple paradigms that shapes and at the most provide clarity to the unknown. </span>
Answer:
Heredity is a process from which traits are transferred from parents to offspring and it is related to genetics because trades are controlled by genes known as genetic code which code the traits.

Answer:
E (Red shows incomplete dominance over white)
Explanation:
This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.
Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.
In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.
