Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes .

The Reproducibility Project is a series of crowdsourced collaborations aiming to reproduce published scientific studies, finding high rates of results which could not be replicated. It has resulted in two major initiatives focusing on the fields of psychology [ 1 ] and cancer biology. [ 2 ]
In 2014, 1 in 3 experienced sexual violence, and there more than 1.2 million deaths. The top three leading causes of death in females between the ages of 15-19 are maternal conditions 10.1%, self-harm 9.6%, and road conditions 6.1%. [20] The causes of teenage pregnancy are vast and diverse.
In botany, the term lusus was used. [1] In horticulture, the spelling clon was used until the early twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o". [2] [3] Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.
Progenitor cells can only differentiate into their "target" cell type. [1] The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely, whereas progenitor cells can divide only a limited number of times. Controversy about the exact definition remains and the concept is still evolving. [2]
However, their funding bodies may require them to publish in scientific journals. The paper is submitted to the journal office, where the editor considers the paper for appropriateness, potential scientific impact and novelty. If the journal's editor considers the paper appropriate, the paper is submitted to scholarly peer review. Depending on ...
Content usually takes the form of articles presenting original research, review articles, or book reviews.The purpose of an academic journal, according to Henry Oldenburg (the first editor of Philosophical Transactions of the Royal Society), is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge ...
A parameter space representing the conditions in which speciation by reinforcement can occur. Here, three outcomes can arise: 1) extinction of one of the initial populations; 2) the initial populations can hybridize; 3) the initial populations can speciate. The outcomes are determined by both initial divergence and level of fitness of the hybrids.
