Which main-sequence on the Hertzsprung-Russell diagram are the least massive?
xxTIMURxx [149]

The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude

Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.

The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.

An organism’s traits are determined by the specific combination of inherited _____.
goldfiish [28.3K]

Answer:

Genes.

Explanation:

Genes are present on DNA that are inherited from parents to their offspring. Genes may be defined as the segment of DNA that ultimately form a particular protein product.

The particular trait of an organism is determined by the specific combination of the inherited genes. The genes are nearly same in all the human beings and there mutation can cause observable phenotype traits.

Thus, the correct answer is option (2).

What was Robert Brown looking at through a microscope when he found evidence of the 1827 scientific concept named in his honor?
Alexxx [7]
He was looking through a microscope at particles trapped in cavities inside pollen grains in water. The concept of Brownian motion is named after him. This is the random motion of particles suspended in a fluid, liquid or gas resulting from their collision with the fast-moving molecules. Here, the patterns of motion of the particles are typically alternations between random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.

The<br> of the Earth on its axis causes
egoroff_w [7]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere
