<span>The answer to this question would be: Autosomal recessive gene.
P</span><span>henylketonuria is an inborn error of metabolism that caused by defect gene that inherited by autosomal recessive. That means the disease is not transmitted by contact as it wasn't caused by pathogens.
It needs two recessive genes to be expressed so the father and mother must have at least one defective gene.</span>
Answer: Liquid
Explanation:
Liquid because, liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
<h3>What is the minimum age of a fossil?</h3>
A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.
