In 1940 Matthew and Marion Stirling found basalt altars at the site of La Venta.
Matthew Stirling was an ethnologist and archaeologist that was sent on expeditions to the Mexican Gulf Coast area to further research the <span>Olmec culture. It was in then years around 1940 that he found with his wife, Marion, several sculptures and monuments in that area. In 1940 he found several altars in La Venta.</span>
Answer:
Phenotypic changes:
When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.
It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.
Evolutionary processes:
It's natural selection that allows the fittest organism to survive. As in the case of the mutants
The plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;
- Sagittal
- Coronal
- Transverse
<h3>What are body planes?</h3>
Body planes are imaginary geometric planes that are used to divide the body into pieces. They are used to analyze interior organs and systems during anatomical procedures.
We have the following body plane types:
- Any vertical plane that separates the body into anterior and posterior halves is referred to as a coronal plane.
- Any plane that separates the body into superior and inferior halves and is nearly perpendicular to the spine is referred to as a transverse plane.
- Any imaginary plane parallel to the median plane is referred to as the sagittal plane.
Based on the three types of plane sections we have, the plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;
- Sagittal
- Coronal
- Transverse

Orbital period is the <span> time taken for a given object to make one complete </span>orbit around another object. Mercury orbits the Sun in 88 days. Therefore, Mercury's orbital period is calculated by (88/365.25) or .241 Earth years. Hope this answers the question.
Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water
Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.
To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
