Male peacocks have large colorful tails that they spread in a fan shape to attract females during courtship. Peahens (female peacocks) are more likely to mate with males that have larger and more colorful tails. As a result, few peacocks have tails with dull coloring.
A male peacock.
Which concept is demonstrated by a decrease in dull coloring?
speciation
biodiversity
natural selection
variation
Answers
Answer:
C
Explanation:
The concept demonstrated by a decrease in dull coloring in male peacocks is natural selection.
What is natural selection?
Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce, passing those traits to the next generation. In the case of male peacocks, having large and colorful tails is a favorable trait because it increases the likelihood of attracting a mate and passing on their genes.
As a result, over time, more and more peacocks have developed larger and more colorful tails through natural selection. The decrease in dull coloring among male peacocks is an example of natural selection favoring a particular trait (large, colorful tails) that confers a reproductive advantage, leading to a change in the population over time. Therefore, the correct concept demonstrated by a decrease in dull coloring is natural selection.

True of false Mendel realized that when he crossed two pea plants that were the offspring of a pea plant with yellow peas and a pea plant with green peas 50% of the offspring had yellow peas and 50% of the offspring had greem peas.
Answers
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).

What are the two main components of the cell cycle
Answers
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.
What is cell cycle?
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.

based on Mr. Kaku's assertion that knowing what the stars are made of is as easy as running starlight through a prism, use the CER method to explain the use of light to determine composition of a star in detail.
Answers
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.

Las células en los tejidos epiteliales están fuertemente unidas a la lámina basal. ¿Qué tipo de proteínas están involucradas en este tipo de unión célula-matriz?
Answers
Answer:
integrinas y lamininas
Explanation:
Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.
