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: the device is called an Electroencephalography machine.
Explanation:
An EEG or Electroencephalography is an electrophysiological monitoring method to record electrical activity of the brain.
Answer: The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled pores. ... The ampullae pores are plainly visible as dark spots in the skin. They provide fish with an additional sense capable of detecting electric and magnetic fields as well as temperature gradients. The skate, a cartilaginous fish related to sharks and rays, possesses a unique electrosensitive sensory organ known as the ampullae of Lorenzini (AoL). This organ is responsible for the detection of weak electric field changes caused by the muscle contractions of their prey. brainliest
Explanation:
Smoking is one of the major reason of Lung cancer. But one may have cancer even if the individual is not a smoker due to radiation, secondary air pollutants.
<h3> What is cancer?</h3>
Cancer is described as the uncontrolled and abnormal growth of cells in one’s body which are arrested in the growth phase of the cell cycle and multiply rapidly and does not mature like normal cells, cancer is more aggressive form of a tumour.
The following describe the relation of smoking with lung cancer
- Cancer is caused by oncogenes activating substances [OAS] some of them causes mutation in the body
- These oncogenic substances in the smoke produced while smoking contains nicotine, hydrocarbons, cyclohydrocarbons and various other factors which converts normal cells into cancerous cells
- Hence,
- smoking
- causes
- oral
- and
- lung
- cancer

Answer:
The phenotype is a purple flower color.
Explanation:
If the dominant allele is present in the genotype, dominant traits will be expressed in the phenotype. Organisms that are heterozygous or homozygous dominant for a certain gene will always express that gene. Since this pea plant has the genotype Pp, the dominant allele (purple flower color) will be shown.
