Answer:
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
- Mitochondrial DNA haplotypes are specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
- Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
- Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
- Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.

How To Use Kepler’s Third Law
The following is an explanation to help you figure out how to use your calculator to solve problems involving Kepler’s Third Law, and three practice problems to check yourself with.
• If I give you the planet’s orbital period:
– Type in the orbital period
– Hit the x2 key on your calculator OR
– Type in “^” followed by “2” and hit the Enter key.
– Next, type in “^” followed by “0.333” and hit the Enter key, OR
– Next, hit the “2nd Function Key” (often says “SHIFT” or “2nd Func” or “INV”) – Hit the xy key and type in 3. Then hit enter.
– The number you see is the planet’s average distance from the sun, in AU.
• IfIgiveyoutheplanet’saverageorbitaldistancefromthesun:
– Type in the orbital distance.
– Hit the xy key on your calculator, type in 3, and hit “Equals” or “Enter” OR – Type in “^” followed by “3” and hit the Enter key.
– If you see a “square root” key on your calculator hit it OR
– Type in “^” followed by “0.5” and hit the Enter key.
– The number you see is the planet’s orbital period, in years.
Examples
• UsetheseexamplestodetermineifyouareusingKepler’sThird Law correctly:
– An asteroid orbits the sun at a distance of 2.7 AU. What is its orbital period?
• Using a = 2.7 AU, you should get P = 4.44 years.
– A dwarf planet discovered out beyond the orbit of Pluto is known to have an
orbital period of 619.36 years. What is its average distance from the sun? • Using P = 619.36 years, you should get a = 72.66 AU.
– Chiron is a dwarf planet that orbits the sun between Saturn and Uranus, and has an average distance from the sun of 14 AU. What is its orbital period?
• Using a = 14.0 AU, you should get P = 52.38 years.
Answer:
the last one
Explanation:
For an organism to become a fossil, it must not decompose or be eaten. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
Answer:
C) The increased ability of an individual plant (above baseline) to withstand further drought after it has received a heat shock, which causes the expression of specific proteins that enable more efficient use of water
Explanation:
In biology, adaptations refer to the characteristics of organisms that allow them to survive and reproduce better in their environment than if they did not possess them. Many of these adaptations are very easy to recognize, such as bird beaks that are highly specific to the food they eat, for example. It is now accepted by science that only natural selection can consistently produce adaptations, although it is important to note that it is not the only evolutionary mechanism. Natural selection, whose idea is mainly attributed to Charles Darwin, acts directly on the phenotypic characteristics of individuals in a population, favoring those who are most likely to survive and reproduce in a given environment over those who are less adapted.
Based on this, we can conclude that adaptation is a biological process that occurs without human manipulation. Thus, we can conclude that among the options given in the above question, the letter C does not represent an example of adaptation. This is because the letter C, shows a plant that showed characteristics favorable to its survival in an inhospitable environment, after human intervention, which, through a thermal shock, caused the expression of specific proteins for that characteristic.
Answer:
The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium. The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation.
