Answer the following question given this paragraph: Amoebozoa The amoebozoans characteristically exhibit pseudopodia that extend like tubes or flat lobes, rather than the hair-like pseudopodia of rhizarian amoeba (Figure 23.26). The Amoebozoa include several groups of unicellular amoeba-like organisms that are free-living or parasites. Q: The nuclear envelope is a double-layered plasma membrane like the cell membrane, although without what? Choices: - cell walls - nucleic acids - cytoplasm - membrane proteins A:
membrane proteins
(Question)
Answer the following question given this paragraph: Because radon is a noble gas, it is inert and generally unreactive. Despite this, exposure to even low concentrations of radon in air is quite dangerous. Describe the physical consequences of exposure to radon gas. Why are people who smoke more susceptible to these effects?. Q: Radon is inert and generally unreactive because it is which kind of gas? Choices: - ignoble gas - transitive gas - ideal gas - noble gas A:
(Answer)
noble gas
Ques: Answer the following question given this paragraph: Some fungi have a different kind of relationship with plants. They are plant parasites. They get food from the plants and cause harm to the plants in return. Fungi are the major causes of disease in agricultural crops. They may eventually kill their plant hosts. Q: What is the major cause of disease in agricultural crops? Choices: - bacteria - drought - pollution - fungi A:
Ans: fungi
(Q).
Answer the following question given this paragraph: Wings and feathers are two adaptations for flight that evolved in birds. Both are clearly displayed in the flying gull in Figure below . Wings evolved from the front limbs of a four-legged ancestor. The wings are controlled by large flight muscles in the chest. Feathers also help birds fly. They provide air resistance and lift. In addition, they provide insulation and serve other roles. Q: Birds adapted wings and weathers for flight during what process? Choices: - migration - variation - emergence - evolution A:
(A).
evolution
Ques:Answer the following question given this paragraph: An electromagnet is a solenoid wrapped around a bar of iron or other ferromagnetic material. The magnetic field of the coil magnetizes the bar, which adds to the strength of the magnetic field. Electromagnets are the strongest magnets made. Q: What are the strongest magnets made? Choices: - permanent magnets - polarized magnets - natural magnets - electromagnets A:

Ans:electromagnets
Ques: Answer the following question given this paragraph: outcompete the green tint of chlorophyll, making these species appear as varying shades of red. Other protists classified as red algae lack phycoerythrins and are parasites. Red algae are common in tropical waters where they have been detected at depths of 260 meters. Other red algae exist in terrestrial or freshwater environments. Green Algae: Chlorophytes and Charophytes The most abundant group of algae is the green algae. The green algae exhibit similar features to the land plants, particularly in terms of chloroplast structure. That this group of protists shared a relatively recent common ancestor with land plants is well supported. The green algae are subdivided into the chlorophytes and the charophytes. The charophytes are the closest living relatives to land plants and resemble them in morphology and reproductive strategies. Charophytes are common in wet habitats, and their presence often signals a healthy ecosystem. The chlorophytes exhibit great diversity of form and function. Chlorophytes primarily inhabit freshwater and damp soil, and are a common component of plankton. Chlamydomonas is a simple, unicellular chlorophyte with a pear-shaped morphology and two opposing, anterior flagella that guide this protist toward light sensed by its eyespot. More complex chlorophyte species exhibit haploid gametes and spores that resemble Chlamydomonas. The chlorophyte Volvox is one of only a few examples of a colonial organism, which behaves in some ways like a collection of individual cells, but in other ways like the specialized cells of a multicellular organism (Figure 23.24). Volvox colonies contain 500 to 60,000 cells, each with two flagella, contained within a hollow, spherical matrix composed of a gelatinous glycoprotein secretion. Individual Volvox cells move in a coordinated fashion and are interconnected by cytoplasmic bridges. Only a few of the cells reproduce to create daughter colonies, an example of basic cell specialization in this organism. Q: Which are the closest living relations to land plants? Choices: - mammals - arthropods - sporozoans - charophytes A:
Ans:
charophytes
