Q: The group of plants that can make their own food from inorganic raw materials in the presence of sunlight are referred to as what? Read this paragraph and choose the correct option from the provided answers: Plants obtain food in two different ways. Autotrophic plants can make their own food from inorganic raw materials, such as carbon dioxide and water, through photosynthesis in the presence of sunlight. Green plants are included in this group. Some plants, however, are heterotrophic: they are totally parasitic and lacking in chlorophyll. These plants, referred to as holo-parasitic plants, are unable to synthesize organic carbon and draw all of their nutrients from the host plant. Plants may also enlist the help of microbial partners in nutrient acquisition. Particular species of bacteria and fungi have evolved along with certain plants to create a mutualistic symbiotic relationship with roots. This improves the nutrition of both the plant and the microbe. The formation of nodules in legume plants and mycorrhization can be considered among the nutritional adaptations of plants. However, these are not the only type of adaptations that we may find; many plants have other adaptations that allow them to thrive under specific conditions. Choices: - symbiotic - autosynonomys - heterotrophic - autotrophic A:
autotrophic

(Question)
Q: What is the volume of the molecules of an ideal gas? Read this paragraph and choose the correct option from the provided answers: Because the molecules of an ideal gas are assumed to have zero volume, the volume available to them for motion is always the same as the volume of the container. In contrast, the molecules of a real gas have small but measurable volumes. At low pressures, the gaseous molecules are relatively far apart, but as the pressure of the gas increases, the intermolecular distances become smaller and smaller (Figure 10.23 "The Effect of Nonzero Volume of Gas Particles on the Behavior of Gases at Low and High Pressures"). As a result, the volume occupied by the molecules becomes significant compared with the volume of the container. Consequently, the total volume occupied by the gas is greater than the volume predicted by the ideal gas law. Thus at very high pressures, the experimentally measured value of PV/nRT is greater than the value predicted by the ideal gas law. Figure 10.23 The Effect of Nonzero Volume of Gas Particles on the Behavior of Gases at Low and High Pressures. Choices: - three - two - one - zero A:
(Answer)
zero

Ques: Q: What is the main function of the cardiovascular system? Read this paragraph and choose the correct option from the provided answers: The main function of the cardiovascular system is transporting substances around the body. Figure above shows some of the substances that are transported in the blood. They include hormones, oxygen, nutrients from digested food, and cellular wastes. Transport of all these materials is necessary to maintain homeostasis of the body and life itself. Choices: - respiration of air - excretion of food waste - coordinate bones and muscles - transporting substances around the body A:
Ans: transporting substances around the body

(A).
boron

Ques:Q: What do you call a type of mixture that has the same composition throughout? Read this paragraph and choose the correct option from the provided answers: This giant Buddha statue, which is a national treasure in Japan, is made of bronze. Bronze consists mainly of copper but also contains some tin. Bronze is an example of a solution. A solution is a type of mixture that has the same composition throughout. Choices: - transition - structure - transfusion - solution A:

Ans:solution

Ques: Q: How many sets of chromosomes does each somatic cell have? Read this paragraph and choose the correct option from the provided answers: Each human somatic cell (a body cell, or every cell other than a gamete) normally has two sets of chromosomes, one set inherited from each parent. These cells are said to have a diploid number of chromosomes. Each set contains 23 chromosomes, for a total of 46 chromosomes. Each chromosome differs in size, from about 250 million nucleotide pairs on the largest chromosome (chromosome #1) to less than 50 million nucleotide pairs on chromosome #22. Each chromosome contains a specific set of genes, as well as regulatory elements and other nucleotide sequences, making each chromosome essential to survival. Choices: - one - four - six - two A:
Ans:
two
