Over the last few years, your friend Angela has developed fibrous nodules in many areas of her skin. She recently confided that she has an inherited disorder of the nervous system that causes these bumps. What disease might Angela have? How can a nervous disorder cause a skin lesion?
What change in the climate may have helped more soay sheep to survive winters?
how does the genetic code allows proteins to be synthesised
with minimal errors taking place? Thanks.

In a pea plant the allele for puple flowernis dominant to the allele for white flower if a white color flowered plant is crossed with a heterozygouos purple plant what would be the genotype and phenotype ratios
a. 27 red, 48 pink, and 24 white flowered plants
b. 18 red and 25 pink flowered plants.
The desert plant Welwitschia mirabilis (Figure 1) is an extraordinary plant, that can survive in the hot, desert where other plants can't survive. On the other hand, food crops have little to no drought resistance or tolerance. The majority of food crops are annuals. In nature, such plants grow only in the rainy seasons, when temperatures are appropriate for vegetative growth; in agriculture, it's called the "growing season”. The Minister of Agriculture, Water, and Forestry has hypothesized that putting Welwitschia mirabilis plant’s survival skills into maize will make it drought tolerant and expand cultivation of maize to marginal arid areas of Namibia.
Imagine, you have been engaged by the Minister of Agriculture, Water, and Forestry as a scientist to make use of the Welwitschia mirabilis surviving skills to develop a maize variety that is drought tolerant, kindly detail all the steps to the Minister on how you would intend to come up with such a maize variety.
