UNO [17]

Answer:

The correct answer is (b) epinephrine.

Explanation:

Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.

In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.

When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

I hope it helps!

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.

solmaris [256]
Both questions in this item are just similar. The area in the cerebral cortex that is involved in the initiation of the motor impulses are localized in the posterior aspect of the frontal lobe. The answer to this item is the third choice.

Frontal lobe is one of the principal areas of the brain that is involved in the motor functions. The specific cortex for this function is commonly called as the M1 or the primary motor cortex.
