Plants absorb blue light well.
Plants are not usually exposed to blue light.
Plants reflect most blue light.
Answer:
The correct answer is "Plants absorb blue light well".
Explanation:
"Chlorophyll A" is one of the most widely used biomolecules in plants, that serves the function of performing photosynthesis. "Chlorophyll A" absorbs light in the blue-violet region, and reflects light in the green-yellow region. The reflected light determines the color of plants, therefore, the properties of "Chlorophyll A" are the reason why most plants are green. In this sense, there are few blue-colored plants because plants absorb blue light well.
Answer:
The correct answer will be-alleles
Explanation:
The instructions of the cell are decoded in a molecule called DNA nucleic acid which provides the code for every metabolic function of the cell.
The part of the DNA which codes for a specific trait is known as the gene which is present in various forms called alleles. These alleles are present on a specific location on DNA called locus.
The alleles express a trait only when the two alleles for the same trait on each chromosome complement each other after fertilization. Therefore, the allele is the correct answer.
B. 46, 23 pairs
C. 90, 45 pairs
D. 140, 70 pairs
The striking similarities in appearance between the human genus Homo and our ancestors, the genus Australopithecus , is sufficient reason to place us both into the same biological tribe (Hominini ). Both genera are bipedal and habitually upright in posture. Humans have been somewhat more efficient at this mode of locomotion. Like australopithecines , early humans were light in frame and relatively short. They were only about 3 ft. 4 in. to 4 ft. 5 in. tall (100-235 cm) and weighed around 70 pounds (32 kg) The evolution of larger bodies occurred later in human evolution. The differences between australopithecines and early humans are most noticeable in the head. Humans developed significantly larger brains and relatively smaller faces with progressively smaller teeth and jaws. In addition, humans became ever more proficient in developing cultural technologies to aid in their survival, while the australopithecines did not.
Late australopithecine Early transitional humanThe immediate ancestors of early humans were most likely late australopithecines. At present, the leading contender for that ancestral species is Australopithecus garhi or possibly Australopithecus africanus.
There may have been one or possibly two species of the first humans living in East Africa--Homo rudolfensis and Homo habilis . The few rudolfensis fossils that have been found are somewhat earlier, dating about 2.4-1.6 million years ago, while the more common habilis remains are around 1.9-1.4 million years old. Rudolfensis apparently was a bit taller and relatively larger brained on average. However, many paleoanthropologists consider the differences to be too slight to warrant a separate species designation. Some have suggested that rudolfensis were males and habilis were females. As a result, they classify them both as a single species--Homo habilis. That is the approach taken in this tutorial.
Answer:
Genetic factor
Explanation:
Height is the trait that is regulated by genetic and environmental factors. The type of the gene present in the genome of the organism and environmental factors such as nutrition, physical activity, surroundings etc. regulate the height of the organisms. If environmental factors are kept constant, the height would be regulated by genetic factors only.
Answer:
the purpose of testing whether the surface texture of the ground affects the distance an object can roll is to understand how different ground textures impact the movement of objects. By conducting this experiment, we can determine whether objects roll farther or shorter distances depending on the surface they roll on.
