Answer:

Fossil A is older than Fossil B

Explanation:

The oldest fossils are those found in deeper layers. This is because sedimentation is a sequential process that increases the original ground level. Thus, the soils in the most superficial layers have suffered less sedimentation impacts, because they are younger.

Fossils are records of living things that existed in the past and were somehow preserved. These living things may be preserved in rocks, sand, ice and, believe me, even within another fossil. Dinosaurs are the big stars when we talk about fossils. Who has never dreamed of discovering a large dinosaur skeleton?

In a certain population of fruit flies, 640 out of 1000 have red eyes, while the remainder have sepia eyes. The sepia eye trait
irga5000 [103]

Answer:

The correct answer is 160.

Explanation:

Based on the given question, the total number of fruit flies is 1000, of which red eye flies are 640. Thus, the number of sepia eye flies will be 1000-640 = 360.  

On the basis of the Hardy-Weinberg equation, p+q = 1, in which p is the rate of recurrence of one allele, that is, dominant and q is the rate of recurrence of the other allele, that is, recessive.  

q^2 for the population is 360/1000 = 0.36, q = 0.6.  

Therefore, p = 1-q = 1-0.6 = 0.4.  

The frequency of homozygous dominant allele is denoted by p^2 = 0.16.  

Hence, the number of homozygous dominant for red eye color would be 16% of 1000 which will be equal to 160.
