Explanation:
The punnet square can be described as a diagram which shows the outcomes of a cross. A punnet square will help us know what will be the probability for a particular trait to occur in the offsprings.
Genes might have the same or different alleles. If the alleles for a gene are similar in an organism, the organism is said to be homozygous for the trait. If the alleles are different, then the organism is termed as heterozygous.
A dominant allele is the one which which suppresses the effect of the recessive allele. A recessive allele gets masked by a dominant allele.
Temperature should it be drawn to 600°-650° Fahrenheit for the newly made spring has been hardened
- Hammer, sear, and trigger are the three main parts of a trigger mechanism.
- . Single-stage trigger is used on the Winchester Model 94 and Marlin Model 336 rifle.
- Lapping is the process called that entails rubbing minute amounts of metal from surfaces that must be precision-finished.
- . Gray to dark blue color would be observe if we achieved the desired drawing temperature of 600-650° Fahrenheit.
- Thermocouple pyrometer is the most common instrument for measuring high temperatures in heat-treating furnaces.
- Cherry to bright cherry color would be observe by reaching the temperature of 1,400°-1,500° Fahrenheit.
- Once the newly made spring has been hardened 600° -650° Fahrenheit temperature would observe.

<u>Answer:</u>
<em>There are innermost serious membranes that cover the heart is Parietal Pericardium.</em>
<u>Explanation:</u>
Heart is <em>covered by pericardium</em> in two sides, inner and outer sides. The inner membrane is parietal pericardium and the outer one is visceral pericardium. Pericardium is made up of <em>fiber tissues</em> that strongly protect the heart from all around.
The<em> main function of pericardium</em> is to protect the heart from any injuries and prevent the infections. The serious pericardium helps in<em> lubricating the heart. </em>
