Answer the following question given this paragraph: In order to study these characteristics, Mendel needed to control the pollination of the pea plants through artificial fertilization . Pollination occurs when the pollen from the male reproductive part of a flower, called the anthers , is transferred to the female reproductive part of a flower, called the stigma . Pea plants are self-pollinating , which means the pollen from a flower on a single plant transfers to the stigma of the same flower or another flower on the same plant. In order to avoid self-pollination, Mendel removed the anthers from the flowers on a plant. He then carefully transferred pollen from the anthers of another plant and using a small paintbrush, dusted the pollen onto the stigma of the flowers that lacked anthers. This process caused cross-pollination. The Figure below shows the location of the male and female parts of a flower. Cross-pollination occurs when pollen from one flower pollinates a flower on a different plant. In this way, Mendel controlled the characteristics that were passed onto the offspring. The product of cross-pollination is known as a hybrid. The ability to cross-pollinate pea plants allowed Mendel to study the offspring of two parents with different traits, such as a tall stem or a short stem. Q: The process of transferring pollen from the male reproductive part of a flower known as the anthers to the female reproductive part of the flower known as the stigma is referred to as what? Choices: - inoculation - fertilization - reproduction - pollination A:
pollination
Q: Answer the following question given this paragraph: How Light-Dependent Reactions Work The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem. Photosystems exist in the membranes of thylakoids. A pigment molecule in the photosystem absorbs one photon, a quantity or "packet" of light energy, at a time. A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become "excited. " The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to "donate" an electron (Figure 5.12). To replace the electron in the chlorophyll, a molecule of water is split. This splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space. Technically, each breaking of a water molecule releases a pair of electrons, and therefore can replace two donated electrons. Q: The overall purpose of the light-dependent reactions is to convert light energy into this? Choices: - photosynthesis - thermal energy - calories - chemical reactions A:
A: chemical reactions

Answer the following question given this paragraph: Distribution of Molecular Speeds The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of molecular speeds. This distribution is called the Maxwell-Boltzmann distribution, after its originators, who calculated it based on kinetic theory, and has since been confirmed experimentally. (See Figure 13.23. ) The distribution has a long tail, because a few molecules may go several times the rms speed. The most probable speed v p is less than the rms speed. Q: The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of what, which is called the maxwell-boltzmann distribution? Choices: - molecular size - molecular rate - molecular shape - molecular speeds A:
(Answer)
molecular speeds
