<u>The</u><u> potential genotypes</u><u> for newborns with brown eyes are</u><u> BB and Bb</u><u>, whereas the potential genotype for newborns with blue eyes is bb.</u>
- According to the information provided above, b = allele for blue eyes is recessive while B = allele for brown eyes is dominant.
- A recessive allele is one that cannot express itself in the presence of a dominant allele, while a dominant allele conceals the effect of a recessive allele.
- A dominant allele expresses itself in the presence of a recessive allele.
- While a dominant allele can express itself in both a homozygous and heterozygous state, a recessive allele can only do so.
- Therefore, newborns with brown eyes will have two genotype options: BB and Bb, whereas those with blue eyes will only have one.

Answer:
17.5 g of manganese-56
Explanation:
Now we have to use the formula;
N/No= (1/2)^t/t1/2
Where
N= mass of manganese-56 left after time (t) = ????
No= initial mass of manganese-56 present = 20 g
t= time taken for N mass of manganese-56 to remain = 7.8 hours
t1/2= half-life of manganese-56 = 2.6 hours
Then we substitute values;
N/20 = (1/2)^7.8/2.6
N/20 = (1/2)^3
N= (1/2)^3 ×20
N= 2.5 g of manganese-56
Mass of manganese-56 that has disappeared after 7.8 hours= 20 -2.5 = 17.5 g of manganese-56

Answer: The human brain and other nerve tissues use mostly as fuel.
The intertidal zone, also known as the foreshore or seashore, is the area above water level at low tide and underwater at high tide. This area can include several types of habitats with various species of life, such as seastars, sea urchins, and many species of coral.
Organisms in the intertidal zone are adapted to an environment of harsh extremes. The intertidal zone is also home to several species from different phyla (Porifera, Annelida, Coelenterata, Mollusca, Arthropoda, etc.). Water is available regularly with the tides, but varies from fresh with rain to highly saline and dry salt, with drying between tidal inundations. With the intertidal zone's high exposure to sunlight, the temperature can range from very hot with full sunshine to near freezing in colder climates.
So, I think the answer should be (B).
