O 2000 m
O 5500 m

Answer:

spectroscopy.

Explanation:

The use of light to determine composition of a star is known as spectroscopy. When astronomers look at an object's spectrum, they can find out its composition based on the wavelengths of light. Spectroscopy is the most common method astronomers use for knowing the composition of stars, planets, and other objects so we can conclude that spectroscopy is the method which is used to determine the composition of stars.

Explanation:

The phylum Echinodermata contains organisms that share a specific set of characteristics, including spiny or bumpy skin. There are five different classes of animals in the phylum: starfish (also known as sea star), brittle stars, echinoids (which include the sea urchins and sand dollars), sea cucumbers, and sea lilies.

Answer:

some physical adaptations that have structurally modified animals to improve their chances of survival include webbed feet, sharp claws, large beaks, wings, feathers, fur, and scales.

Answer:

False

Explanation:

Mendel realized that the F2 had a phenotypic ratio 3:1, meaning 3/4 = 75% were yellow and 1/4 = 25% green.

Mendel observed that the F1 expressed only one of the alternative variants (in this case, only yellow seeds appeared), while the other variant (green) disappeared. Mendel named dominant the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named recessive the second alternative variant.

Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.

Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (yellow and green) and that the pair separates (segregates) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Answer: Low power is usually used for scanning a slide in order to view the content of the slide very clearly without missing any cell. The lower the magnification, the higher the view.

In eukaryotic cells or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. These events include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm and other components into two daughter cells in a process called cell division.

In cells with nuclei (eukaryotes, i.e., animal, plant, fungal, and protist cells), the cell cycle is divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the mitotic phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of cellular components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.

In cells without nuclei (prokaryotes, i.e., bacteria and archaea), the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

Symbiosis - both species benefit

parasitism - one species benefit and the other species is harmed

Bye :-)

Interactions between two or more species are called interspecific interactions.

The interactions described are;

There are 5 types of interspecific interactions:

Thus, we can conclude that

i) Commensalism- One species benefits and the other species is neither harmed nor helped.

ii) Mutualism- Both species benefit.

iii) Parasitism- One species benefits and the other species is harmed.

Explanation:

La afinidad electrónica se define como la energía liberada cuando un átomo en su estado de tierra acelera un mol de electrones para formar un mol de iones negativos.

La afinidad electrónica es una tendencia periódica que disminuye en el grupo pero aumenta a lo largo del período.
