Answer:
D (purple flower plant is dominant)
Explanation:
Gregor Mendel was regarded as the "Father of Genetics" because of his outstanding contribution to discovering the pattern of inheritance. In his experiments with purebreeding purple and white-flowered plants, he discovered that the F1 offsprings were all purple-flowered.
This observation made him to propose his LAW OF DOMINANCE, which states that one allele of a gene is capable of masking the expression of another in a heterozygous state. In this case of flower colour gene, the allele for purple color (P) is masking the gene of the white colour (p) in a combined state. Hence, purple allele is said to be DOMINANT over white allele.
He discovered that the white allele was being masked when he performed a dihybrid cross i.e. F1 self cross to derive a plant with white flowers.
Answer:
Tissue
Explanation:
Each cell type has a special feature that enables it to perform a particular function effectively. Thus, cells are said to be specialized to perform different functions. Groups of specialized cells are assembled together to form a tissue. Examples are muscle, skeletal and nervous tissues. Different tissues working together form organs like the heart, kidney and eyes
Probiotics are healthy bacteria which live in the human body, in particular in the intestines, and help fight disease. They are living microorganisms which, when ingested, have beneficial effects on the human body. The most common form of probiotic is Lactobacillus Acidophilus.
It is estimated that there are several trillion friendly bacteria comprising over four hundred species in the average human gastrointestinal tract. By body weight, each of us carries around approximately four pounds of intestinal microflora!
They counteract damage done to the body due to antibiotic use and stimulates the immune system to function better when you are relatively healthy, but when you’re sick, they can also contribute significantly to relief of health problems ranging from indigestion and diarrhea to colon and liver cancer.
Lactobacillus Acidophilus is also involved in the production of B vitamins (niacin, folic acid, and pyridoxine) during the digestive process.
Some of the ways probiotics appear to improve health include: alleviating lactose intolerance, reducing and preventing diarrhea, defending against infections, enhancing the immune system, reducing inflammation, preventing allergic reactions, and reducing chronic constipation
