Answer the following question given this paragraph: Streptophytes Until recently, all photosynthetic eukaryotes were considered members of the kingdom Plantae. The brown, red, and gold algae, however, have been reassigned to the Protista kingdom. This is because apart from their ability to capture light energy and fix CO2, they lack many structural and biochemical traits that distinguish plants from protists. The position of green algae is more ambiguous. Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch. Cells in green algae divide along cell plates called phragmoplasts, and their cell walls are layered in the same manner as the cell walls of embryophytes. Consequently, land plants and closely related green algae are now part of a new monophyletic group called Streptophyta. The remaining green algae, which belong to a group called Chlorophyta, include more than 7000 different species that live in fresh or brackish water, in seawater, or in snow patches. A few green algae even survive on soil, provided it is covered by a thin film of moisture in which they can live. Periodic dry spells provide a selective advantage to algae that can survive water stress. Some green algae may already be familiar, in particular Spirogyra and desmids. Their cells contain chloroplasts that display a dizzying variety of shapes, and their cell walls contain cellulose, as do land plants. Some green algae are single cells, such as Chlorella and Chlamydomonas, which adds to the ambiguity of green algae classification, because plants are multicellular. Other algae, like Ulva (commonly called sea lettuce), form colonies (Figure 25.7). Q: Cells in green algae divide along cell plates called what? A:

OPTIONS:
- chloroplasts
- cellulose
- xanthophylls
- phragmoplasts

Answer: phragmoplasts

Problem: OPTIONS:
- mutant traits
- autolysis traits
- maladaptive traits
- polygenic traits
Q: Answer the following question given this paragraph: Many human traits are controlled by more than one gene. These traits are called polygenic traits (or characteristics). The alleles of each gene have a minor additive effect on the phenotype. There are many possible combinations of alleles, especially if each gene has multiple alleles. Therefore, a whole continuum of phenotypes is possible. Q: What human traits are controlled by more than one gene? A:
Answer: polygenic traits

Problem:OPTIONS:
- scientific experiments
- informal theories
- scientific hypotheses
- scientific theories

Answer the following question given this paragraph: Scientific theories are broad explanations that are widely accepted as true. This is because they are supported by a great deal of evidence. Q: What are broad explanations that are widely accepted as true? A:
****
A: scientific theories

Answer the following question given this paragraph: Flowering vascular plants also have diverse leaves. However, the leaves of all flowering plants have two basic parts in common: the blade and petiole (see Figure above ). The blade of the leaf is the relatively wide, flat part of the leaf that gathers sunlight and undergoes photosynthesis. The petiole is the part that attaches the leaf to a stem of the plant. This occurs at a node. Q: The leaves of all of what type of plants have two basic parts in common: the blade and petiole? A:
OPTIONS:
- perennials
- deciduous
- evergreen
- flowering plants
flowering plants

Answer the following question given this paragraph: Weeks 1624 Once the respiratory bronchioles form, further development includes extensive vascularization, or the development of the blood vessels, as well as the formation of alveolar ducts and alveolar precursors. At about week 19, the respiratory bronchioles have formed. In addition, cells lining the respiratory structures begin to differentiate to form type I and type II pneumocytes. Once type II cells have differentiated, they begin to secrete small amounts of pulmonary surfactant. Around week 20, fetal breathing movements may begin. Q: Alveolar ducts and broncioles are developing parts of what organ system? A:
OPTIONS:
- nervous
- immune
- digestive
- respiratory

Answer: respiratory

input with options: Answer the following question given this paragraph: Electromagnetism is associated with charge and is a fundamental force of nature, like gravity. If charges are static, the only manifestation of electromagnetism is the Coulomb electric force. In the same way that gravitational force depends on mass, the Coulomb electric force depends on the property known as electric charge. Like gravity, the Coulomb electric Force decreases with the square of the distance. The Coulomb electric force is responsible for many of the forces we discussed previously: the normal force, contact forces such as friction, and so on - all of these forces arise in the mutual attraction and repulsion of charged particles. Q: What property does coulomb electric force depend upon? A:
OPTIONS:
- electric case
- electric neutral
- electric half
- electric charge
output:
electric charge
