Answer:
Neurospora.
Explanation:
Beadle and Tatum experiment shows one gene one enzyme hypothesis. According to this, a single enzyme is encoded by each gene. This idea is not accepted in today's world.
Beadle and Tatum performed experiment on the neurospora. They chosed neurospora in their experiment because neurospora shows the fast life cycle with alternation of generation. The genetic experiments can be easily performed on neurospora.
Thus, the correct answer is option (c).
Answer:
Given the current environment in most developed countries, it is a challenge to maintain a good balance between calories consumed and calories burned, although maintenance of metabolic balance is key to good health. Therefore, understanding how metabolic regulation is achieved and how the dysregulation of metabolism affects health is an area of intense research. Most studies are focused on the hypothalamus, which is a brain area that acts as a key regulator of metabolism. Among the nuclei that comprise the hypothalamus, the arcuate nucleus is one of the major mediators in the regulation of food intake. The regulation of energy balance is also a key factor to ensure the maintenance of any species because of the dependence of reproduction on energy stores. Adequate levels of energy reserves are necessary for proper functioning of the hypothalamus-pituitary-gonadal axis. This review discusses valuable data presented in the 2015 edition of the International Workshop of Neuroendocrinology concerning the fundamental nature of the hormonal regulation of the hypothalamus and the impact on energy balance and reproduction.

Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
Answer:
Substitute the P-II promoter (makes RNA II) for one that is stronger, or mutate the P-I promoter to make it weaker.
Plants use their roots to get water, they collect carbon dioxide through openings on their leaves called stomata.
