A malignant tumor has begun to allow cancers cells to enter the brain. Maligant tumors divide into primary tumors which start with the brain and secondary tumors which scatter from somewhere else which is called brain metastasis tumors.

There are symptoms which produce by brain tumors. For example, a problem with vision, vomiting, mental changes and headache. The important problem may include having difficulty in walking. The cause of brain tumor is unknown but the most risk factor is that it may be inherited neurofibromatosis, ionizing radiation and vinyl chloride.

Medulloblastoma is the type of malignant tumor in children. The medical examination which is computed by tomography can diagnose it. Treatment of a malignant tumor is chemotherapy, radiation therapy and surgery.

A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of produ
Reil [10]

Answer: The probability of producing offspring with genotype Rr is 100%.

Explanation-

Round seed is a dominant trait ( depicted by dominant R allele) whereas wrinkled seed is a recessive trait ( depicted by recessive allele r).

According to the law of segregation of genes, the alleles will separate from one another during gamete formation.

Pea plant with round seeds will produce two gametes that is R and R whereas plant with wrinkled seeds will produce r and r gametes.

When the parents are crossed, they will result in the offspring with genotype Rr ( that will exhibit round seed phenotype).

Refer punnett square.

The medial geniculate nucleus is the thalamic nucleus responsible for processing of somatosensory information from the body.
Anuta_ua [19.1K]

Answer:

False

Explanation:

Thalamic nuclei can be differentiated in their relationship to the cerebral cortex into specific thalamic nuclei (have links to very specific cerebral cortical areas) and nonspecific thalamic nuclei, which maintain connections to wider areas of the cortex.

These nuclei nuclei transmit impulses to the sensory areas of the brain, such as: the lateral geniculate body (nucleus) that will transmit visual impulses; the Medial Geniculate Body (nucleus), which will transmit auditory impulses; and the Posterior Ventral Body (nucleus) that will transmit impulses to taste and somatic sensations, such as touch, pressure, vibration, heat, cold and pain. Thus, we can conclude that the medial geniculate nucleus is the thalamic nucleus responsible for the transmission of auditory impulses.
