Plants use energy from sunlight to turn water and carbon dioxide from what they get into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. In photosynthesis, the energy in light is absorbed by photopigments.
Answer:
According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes.
Answer:
16 pg at the end of S
16 pg at the end of G2
Explanation:
A cell has 8 pg of DNA per nucleus in G1.
During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.
During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.
Answer:
The species of wild rabbits that are brown would most likely have a harder time adapting than the white rabbits to the new environment.
Explanation: The brown rabbits are going to have a hard time living in the snow mostly because of their color. The brown rabbit is more likely to be able to live in the desert because they can camouflauge with their surroundings (the sand). Therefore, camouflaging in the white snow to escape a predator would be impossible for brown rabbits, since they could easily be spotted. Furthermore, the white rabbits would have a higher chance of survival since they can camouflage easier in the snow.
Answer: The Joker is a very popular character with boys, perhaps because laughter is part of their own “mask of masculinity.” A potential negative consequence of this stereotype is the assumption that boys and men should not be serious or emotional. However, researchers have also argued that humorous roles can be used to expand definitions of masculinity.
The Jock is always willing to “compromise his own long-term health; he must fight other men when necessary; he must avoid being soft; and he must be aggressive.” By demonstrating his power and strength, the jock wins the approval of other men and the adoration of women.
The Strong Silent Type focuses on “being in charge, acting decisively, containing emotion, and succeeding with women.” This stereotype reinforces the assumption that men and boys should always be in control, and that talking about one’s feelings is a sign of weakness.
The Big Shot is defined by his professional status. He is the “epitome of success, embodying the characteristics and acquiring the possessions that society deems valuable.” This stereotype suggests that a real man must be economically powerful and socially successful.
The Action Hero is “strong, but not necessarily silent. He is often angry. Above all, he is aggressive in the extreme and, increasingly over the past several decades, he engages in violent behavior.”
The Buffoon commonly appears as a bungling father figure in TV ads and sitcoms. Usually well-intentioned and light-hearted, these characters range from slightly inept to completely hopeless when it comes to parenting their children or dealing with domestic (or workplace) issues.
