Answer:
when marine water evaporates
Answer: The sugar in DNA is called a deoxyribose because it doesn't have a hydroxyl group at the 2' position. Instead it just has a hydrogen

Answer:
<u>Condensation</u>
Explanation:
Disaccharides are formed when two monosaccharides condense with loss of a water molecule. A glycosidic bond joins the two monosaccharides together.
Glucose + Galactose → Lactose + Water
Answer:
0.9342
Explanation:
The Hardy-Weinberg equation states that p² + 2pq + q² = 1,
where p is the frequency of the dominant 'normal' (n) allele and q is the frequency of the recessive 'albino' (a) allele in the population, while q² represents the frequency of the homo-zygous albino genotype (aa), p² represents the frequency of the homo-zygous normal genotype (nn) and 2pq represents the frequency of the heterozygous genotype (na).
In this case, the frequency of individuals in the population that have the genotype aa (q²) is equal to 26/6000 = 0.004333. In consequence, q is equal to √ 0.004333 = 0.0658.
Moreover, the allele frequency of the normal (n) allele p is equal to 1 - q = 1 - 0.0658 = 0.9342, so p² (nn) = (0.9342)² = 0.8727.
Finally, the frequency of the heterozygous genotype (na) is 2pq = 2 x 0.9342 x 0.0658 = 0.123.
