In older rock layers we find fossils of living things that no longer exist on earth.

Explanation:

Scientists often refer back to fossils found within sedimentary rocks to back their idea that life forms have changed over time.

Fossils are the preserved remains of organisms that once lived on earth. Special conditions must be in play before an organism can become a fossil like presence of hard parts.

  • Fossils are indicators of ancient life forms that has once lived.
  • They provide us with important clues to the nature of organisms that existed in time past.
  • Using phylogenetic relationship with their present day ancestors, it is possible to trace the evolutionary history of a specie.

photoshop1234 [79]

Answer:

$55,400

Explanation:

To determine the cash paid for salaries and wages during the year.

wages payable (beginning of the year) = $800

wages payable (end of the year) = $2600

Income statement on wages and salaries for the year = $57,200

cash paid for Salaries and Wages during the year = (Salaries and Wages Expense + wages payable at the beginning of the year) - wages payable at the end of the year

$(57,200 + 800) - $2600

$(58000-2600)

= $55,400

A man has blood type O, Rh negative. These are both recessive traits. He is married to a woman who has blood type A, Rh positive
frosja888 [35]

IAIARr is the genotype of the mother.

<h3><u>Explanation</u>:</h3>

The blood groups are the heredity characteristics of the individual which governs what antigen will be present in blood and what antibody will be present in the blood plasma.

The blood group has the genetic characteristics where A and B are dominant characters and O is the recessive character. Co Dominance is seen in case of blood grouping. Similar characteristics is seen with Rh character too where Rh positive is the dominant character and Rh negative is recessive.

The father has both the recessive characteristics. So he needs to be genetically homozygous which means that he has genetic setup of IoIo and rr.

Two child born has character of A blood group and rh positive, but the other child is A blood grouped and rh negative.

So the mother ought to be heterozygous with respect to Rh group, but she is homozygous with respect to blood group.

So her genetic setup is IAIARr.
