Various parts of the human body have specific receptors for some type of tactile stimulus, such as the hands and feet. The tactile receptors present in the hands are called Meissner's corpuscles, while those present in the feet are known as Ruffini's corpuscles. What are the main functions of these corpuscles?

In a particular species of plant, the colour of the flowers is determined by a single pair of alleles, where the dominant allele (A) gives rise to red flowers and the recessive allele (a) produces white flowers. A gardener crosses two heterozygous plants (Aa) and wants to predict the expected ratio of red and white flowers in the next generation. Taking into account Mendel's First Law on the segregation of alleles, what is the likelihood that a plant from this cross will have white flowers?

During puberty, significant changes occur in the human body due to the activation of the reproductive system. This process is controlled by hormones, which act on the sexual organs and also on other body systems. Explain how the pituitary gland and the hypothalamus, both located in the brain, interact to control puberty. In addition, discuss the role of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and human chorionic gonadotropin (hCG) in the development and maintenance of reproductive structures, and how these hormones can be targets for regulation in infertility treatments. Finally, mention and briefly explain a medical condition that may arise due to alterations in the functioning of the reproductive system during puberty.
