Q: The presence of what in leaf cells makes most leaves appear green? Read this paragraph and choose the correct option from the provided answers: 30.4 | Leaves By the end of this section, you will be able to: Identify the parts of a typical leaf Describe the internal structure and function of a leaf Compare and contrast simple leaves and compound leaves List and describe examples of modified leaves Leaves are the main sites for photosynthesis: the process by which plants synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells. However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll. The thickness, shape, and size of leaves are adapted to the environment. Each variation helps a plant species maximize its chances of survival in a particular habitat. Usually, the leaves of plants growing in tropical rainforests have larger surface areas than those of plants growing in deserts or very cold conditions, which are likely to have a smaller surface area to minimize water loss. Choices: - hydrogen - sodium - carbonate - chlorophyll A:
chlorophyll

Q: Life span is distinct from what, which means the sequence of stages a plant goes through from seed germination to seed production of the mature plant? Read this paragraph and choose the correct option from the provided answers: Plant Life Spans The length of time from the beginning of development to the death of a plant is called its life span. The life cycle, on the other hand, is the sequence of stages a plant goes through from seed germination to seed production of the mature plant. Some plants, such as annuals, only need a few weeks to grow, produce seeds and die. Other plants, such as the bristlecone pine, live for thousands of years. Some bristlecone pines have a documented age of 4,500 years Figure 32.29. Even as some parts of a plant, such as regions containing meristematic tissuethe area of active plant growth consisting of undifferentiated cells capable of cell divisioncontinue to grow, some parts undergo programmed cell death (apoptosis). The cork found on stems, and the water-conducting tissue of the xylem, for example, are composed of dead cells. Choices: - feeding cycle - society cycle - spin cycle - life cycle A:
life cycle

Q: Q: What is located beneath the lithosphere? Read this paragraph and choose the correct option from the provided answers: Beneath the lithosphere, the asthenosphere is solid rock that can flow. Choices: - hydropshere - troposphere - magnetosphere - asthenosphere A:
A: asthenosphere

Question: Q: Earth spinning as air moves over its surface causes what? Read this paragraph and choose the correct option from the provided answers: Earth is spinning as air moves over its surface. This causes the Coriolis effect. Winds blow on a diagonal over the surface due to Coriolis effect. From which direction do the northern trade winds blow?. Choices: - seasons - centrifugal effect - axial tilt - coriolis effect A:
Answer: coriolis effect

Q: A change in one or more physical properties of matter without any change in chemical properties is called what? Read this paragraph and choose the correct option from the provided answers: A physical change is a change in one or more physical properties of matter without any change in chemical properties. In other words, matter doesn't change into a different substance in a physical change. Examples of physical change include changes in the size or shape of matter. Changes of statefor example, from solid to liquid or from liquid to gasare also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting. Four examples of physical change are pictured in the Figure below . You can learn more about physical changes and why they occur by watching the video at this URL:. Choices: - negative change - positive change - atmospheric change - physical change A:
**Answer**
physical change

Q: Structural rearrangements of what include partial duplications, deletions, inversions, and translocations; duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities? Read this paragraph and choose the correct option from the provided answers: Chromosome Structural Rearrangements Cytologists have characterized numerous structural rearrangements in chromosomes, including partial duplications, deletions, inversions, and translocations. Duplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities. Cri-du-chat (from the French for "cry of the cat") is a syndrome associated with nervous system abnormalities and identifiable physical features that results from a deletion of most of the small arm of chromosome 5 (Figure 7.11). Infants with this genotype emit a characteristic high-pitched cry upon which the disorder's name is based. Choices: - neutrons - phenotypes - cells - chromosomes A:
(Answer)
chromosomes
