Fifty years ago, genetic testing did not exist. If we wanted to prove whether someone was related, our best option was blood typing. Now, Elvis Presley was a wildly famous musician who died in 1977. Before his death, it was rumored he fathered a child with someone other than his wife whilst they were living in Hawaii. Prior to Elvis's death, this same woman would take her son to visit him there at least once a year. She also had blood tests done to prove Elvis was the father and tests showed it was possible. Her grandson is alive now, and looks very much like Elvis as you can see below. The grandson is on the left and Elvis is on the right. They have the same O+ blood type, sing beautifully, and both play the guitar. If you were using blood type to determine whether Elvis (whose blood type is O+) was the father of someone, which of these blood types would not have been possible for any of his children?
Type A -
Type B +
Type O-
Type AB+

How can a shipwreck that is left in place on the ocean floor benefit marine life?.
Answer:
Nutrition and Shelter
Explanation:
the remaining fossils and foods can be used as nutrition for algae and fish living in that area. as well as the shelter used for fish to hide and reproduce/rest/cool down.
Answer:
I got you
Explanation: How can a shipwreck that is left in place on the ocean floor benefit marine life - The fossil fuel in its engines can become food for algae and fish. Its interior can release oxygen from the surface to the deep ocean. It can provide a hard surface where organisms can attach and live. Also, the wreck can become an artificial Reef and protection from predators.

A planet has been observed orbiting a nearby star. This star has a mass of 3. 5 solar masses, and the planet is 4. 2 AU from the star. What is the planet’s orbital period in Earth years? Round your answer to the nearest whole number. Earth years.
Planets rotate and revolve around the sun in fixed orbits and are at a specified distance from the sun. The planet's orbital period will be 4.6 years.
What is an orbital period?The time taken by the planet to complete one revolution around the sun in their fixed orbits is called the orbital period of the planet.
The period can be determined using Kepler's third law:
[tex]\rm T^{2} = \dfrac{4\pi ^{2}}{GM}\times a^{2}[/tex]
Where,
The orbital period of a planet (T) = ?Distance form sun (a) = [tex]\rm 6.28\times 10^{11} m[/tex]Gravitational constant (G) = [tex]\rm 6.67 \times 10^{-11} m^{3}kg^{-1}s^{-2}[/tex]Mass of the parent star (M) = [tex]\rm 6.96 \times 10^{30} kg[/tex]Substituting values in the above equation:
[tex]\begin{aligned}\rm T&= \sqrt{\dfrac{4\pi ^{2}}{6.67\times 10^{-11}\times 6.96\times 10^{30}}\times (6.28\times 10^{11})^{3}} \\\\&=145,128,196\;\rm seconds\end{aligned}[/tex]
Therefore, 4.6 years is the orbital period of the planet.

What happens to cells when they undergo differentiation?.
Answer:
It causes deceases.
Explanation:
The process through which a cell transforms from one cell type to another is known as cellular differentiation. In most cases, the cell transforms into a more specialized form. As a multicellular organism develops from a basic zygote to a complex system of tissues and cell types, it undergoes many stages of differentiation.

Which elements are common to all four of the base nucleotides found in DNA? Select all that apply.
nitrogen
sodium
carbon
iron
Explanation:
The nitrogenous bases of nucleotides are organic (carbon-based) molecules made up of nitrogen-containing ring structures. Why is it called a base? Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T)
Answer:
nitrogen, carbon
Explanation:
DNA nucleotide consists of a phosphate group, deoxyribose sugar and one of the 4 possible bases- adenine, guanine, cytosine and thymine.
The elements that are found in four of the bases are carbon, nitrogen and hydrogen.
Base pairing occurs between a purine and a pyrimidine. Purines are fused double ring structures and can be adenine or guanine, while pyrimidines are single ring structures and can be cytosine and thymine in the case of DNA.
