The diagram below shows undisturbed fossils in sedimentary rocks in two different locations. The picture shows two layers of rocks. In location 1, the top layer has fossils of leaves, the middle layer has fossils of fish, and the bottom layer has fossils of sea shells. In location 2, the top layer has fossils of sea shells; the middle layer has fossils of fish, and the bottom layer has fossils of leaves.

Which of these conclusions is most likely correct about the locations? (2 points)

Group of answer choices

Location 1 is a forest at present and Location 2 was a forest in the past.

Both the locations are submerged under water.

Both the locations have dense forests.

Location 2 is a forest at present and Location 1 was a forest in the past.

answer;

medical directors

explanation;

medical directors grants and supervises the privilege or permission to use an aed on an ambulance.

other roles of a medical director includes;

-provide medical leadership, including coordination with local ems and 911 centers.

-provide guidance in equipment selection and deployment

-develop guidelines for responder actions

-oversee medical care that is rendered through the program, including review of all responses to medical emergencies

-ensure appropriate initial training and skill maintenance

-assume overall responsibility for the conduct and operation of all patient care related activities

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
