This pedigree doesn't show an autosomal dominant trait because 3,4 are carriers, passing the gene to their offsprings but don't manifest the phenotype. This pedigree can represent an autosomal recessive gene based on what I just mentioned. We know that this is an autosomal trait because it seems to affect both genders equally.
Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
Answer:
Mesozoic Era
Explanation:
The "Mesozoic Era" is divided into three periods: <em>Triassic, Jurassic and Cretaceous.</em> During the last period (Cretaceous), which was considered the longest, the extinction of reptiles occurred and the new mammals appeared. This event was also known as the "Cretaceous-Paleogene Extinction Event." Around <em>3/4 of plants and animals died</em>. Such event became significant boundary that laid between the Cenozoic Era and the Mesozoic Era. This made it significant in geologic history.
