Answer:(A) Paleoanthropology
Explanation:
Anthropology is discipline which studies about human beings their evolutionary development, culture and societies.
Paleoanthropology is the branch of anthropology which studies the early development of the anatomically the modern humans. This is done through reconstruction of the kinship lines which can be achieved with biological evidences like skeletal remains, footprints, fragments of bones and cultural evidences like stone tools, and artifacts formed and developed by modern humans.
According to the given situation, the chimpanzees were seen to develop weapon against the small primates called as galagos. As chimpanzees were the ancestors of modern humans thus paleoanthropology, which is the primary type of biological anthropology can be used to address the research.
The possible genotypes and phenotypes for the offspring are:

Answer:
A. The use of only the most productive breeds improves genetic diversity.
This is just an educated guess. As the purple pigment, caused by anthocyanins, are on the bottom side of the plant, their purpose could probably be to direct the light.
Specifically, a purple pigment on the bottom of the plant would absorb certain wavelengths near the purple spectrum, and reflect other wavelengths back toward the portion of the plant with chlorophyll. In this way, light does not simply pass through the leaf, instead it is reflected back in towards the chlorophyll to maximize the amount of light being used for photosynthesis.
Answer:
Epiblema, cortex, endodermis, pericycle
Explanation:
The outer most layer of monocot root is rhizodermis or epiblema which has compactly arranged tubular cells and unicellular root hair as their extension. Just beneath the epiblema are multiple layers of parenchymatous cells with ample intercellular space, it is cortex. The inner most layer of cortex forms endodermis which has compactly arranged barrel shaped cells with casparian strips at their anticlinal wall. The uniseriate layer of thin walled parenchymatous cells, present below endodermis, which are sclerified in old roots makes pericycle. The vascular bundles are present as alternating strands of xylem and phloem, the discrete xylem strands alternated with phloem strands. The central parenchymatous cells form pith.
