What does biology mean? Explain what is meant by the word centriole as used in biology. In 150 words, explain sexual reproduction. Relating to biology, explain the term 'polyribosome'. What is the definition of the term Biology as applied in science study?
Spermatazoa are the male gamete,meaning they are the cells that fuse with the egg in fertilization giving rise to the embrion and future baby.
Define the term Biology in reference to it as a branch of Science. Define what is agenesis. What does the term genomics mean? In terms of biology, describe the term, "phenotype". Define nutrients. What does malignant mean in terms of biology? What is the term used to refer to the grad...
Since Fisher’s time, it has been realized that genes can sometime influence the chromosome(染色体)or gamete(配子)in which they find themselves so that the game will be more likely to participate in fertilization. If such a gene occurs on a sex determining (X or Y) chromosome, then highly...
Both of these modes have led to science fiction affecting the future rather than predicting it. (19) The fact that artificial intelligence may never be realised in practice does not make fiction about it nugatory. Science Fiction Literature versus Science Fiction Films ...
However, despite the now sterling record of ICSI it does not assure a successful outcome for every patient. This can be due, for instance, to the inability of the spermatozoon to activate the oocyte, and applies obviously in cases where spermatozoa are absent from the ejaculate or testicular ...

The mean density of large prey species differed significantly among habitats for decapods and echinoids (nested ANOVA,F2,14.4= 5.225,P= 0.020 andF2,21.8= 4.322,P= 0.026, respectively). Decapods and echinoids were significantly more abundant on coral reefs than in mangroves and seagrass beds (Figu...
Nondisjunction may occur whenever a cell divides its chromosomes. This happens during normal cell division (mitosis) and gamete production (meiosis). Mitosis DNA replicates prior to cell division. The chromosomes line up in the middle plane of the cell during metaphase and the kinetochores of sister...
The mean oocyte age for patients conceiving MZT was lower when compared with all other gestation types (32.9 ± 5 years and 34.3 ± 6 years, respectively; P=.004). In fact, there was a 4% decrease in the odds of conceiving an MZT with each 1-year increase in oocyte age. Identified ...
