Answer:
The correct answer is ''It creates food that they can eat.''
Explanation:
The first link or first trophic level, of any food chain is always represented by the producers, (plants, which are photosynthetic organisms), autotrophic organisms, which are capable of transforming the light energy of the sun into a type of energy that can be used by the rest of the living beings. All heterotrophic organisms depend on these energy and matter conversions for their subsistence, that is, animals eat plants and take advantage of those organic compounds to create their own body structure, since heterotrophs, like humans, cannot carry out the photosynthesis, obtain energy by consuming autotrophs and their derivatives.
Answer:
B. F1
Explanation:
Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
<h2>1. Earth's Plates 2. Convection currents 3. Heat from Earth's core </h2>
Explanation:
- Plate tectonics, hypothesis dealing with the elements of Earth's external shell—the lithosphere—that changed Earth sciences by giving a uniform setting to understanding mountain-building forms, volcanoes, and seismic tremors just as the development of Earth's surface and recreating its past landmasses and seas
- The idea of plate tectonics was figured during the 1960s
- The hypothesis of plate tectonics depends on an expansive amalgamation of geologic and geophysical information
47 chromosomes instead of 46 because there are 3 chromosomes in pair 21. This is called Down syndrome, described most recently by Lejune in 1958
