Abstract

The flower-heads of the sunflower are well-suited for insect pollination as the crowding of the flowers ensures conspicuousness and the pollination of a maximum number of flowers by a single insect visit. The honey, secreted at the base of the style, is protected by the corolla tube from visits of short-tongued insects. When the flower open the receptive surfaces of the two stigmas are pressed together and occupy a position at the base of the tube formed by the united anthers; the latter split on the inside and the liberated pollen fi ....etc

study of pollination in sunflower and legume project

Abstract
Cratylia argentea is a high-quality forage legume shrub, with particular potential for the subhumid tropics owing to its adaptation to acid and infertile soils and drought tolerance. However, lack of knowledge about the ability of this species to self-pollinate makes purity maintenance of accessions difficult. Studies were conducted to investigate whether the gametes of C. argentea flowers
are self-compatible, and to verify the dependence of reproduction on insects. Pod set and seed ....etc

Abstract

Here, students learn that the comparison of DNA sequences is important to a wide variety of applications in medicine and biology, including the analyses of ecosystem biodiversity, cancer mutations and the evolution of viruses. The students learn that specialized yet inexpensive digital hardware based on field programmable gate arrays can help speed the analysis of DNA sequences. They design and test a simple implementation of the Smith-Waterman algorithm that is broadly used for DNA sequence c ....etc

Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.

Cancer harms the body when altered cells divide uncontrollably to form lumps or masses of tissue called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that ....etc
