biology competition 2021

Sperm competition is the competition between sperm from different males to fertilize the same female's eggs. In many species, females may mate with multiple males. This has led to the evolution of various adaptations in males. For example, some male animals produce large quantities of sperm to increase the chances of their sperm reaching and fertilizing the egg. Also, the shape and motility of sperm can be specialized for better competition. In some insects, male genitalia have evolved in complex ways that may help them remove or displace the sperm of rival males already present in the female reproductive tract.

There are many masterpieces about biology. The following are some of the famous masterpieces: Cell Biology:A Clinic Introduction to the Study of Living Systems by Richard B Ansell. Biochemistry:The Biochemistry of Life by D. W. Anslinger. The Evolution of Life by E O Wilson. 4. The Study of Living Things by David R Fisher. 5. The animal behavior of Humans and other animals by Richard A. Ishii Yoko. 6. The botany of plants by John R. O. These masterpieces covered many aspects of biology, from the cellular and molecular level to the macro ecology. They all made important contributions to the development and research of biological science.

In biology, something novel could be a newly discovered species or a unique biological mechanism that hasn't been previously identified.

Biology was not literature. Biology was a science that studied life phenomena and organisms. It mainly focused on the nature, composition, evolution, growth, development, disease, health, and other aspects of life. Literature is an art subject that focuses on language, imagination, emotions, and expression. It aims to convey the author's thoughts, emotions, and values through words. Although biology and literature intersected, they were fundamentally different. Biology was a natural science that required experiments, observations, and theoretical models to explain biological phenomena, while literature was an art form that required words, poems, plays, novels, and other means to express the author's thoughts, emotions, and values. Therefore, biology was not a part of literature, but there was a certain connection and intersection between the two.

Novel protein biology refers to the study of new or previously uncharacterized proteins and their functions and roles in living organisms.

Novel properties in biology can be things like unexpected patterns of evolution in a particular group of organisms, or novel symbiotic relationships between species that haven't been documented before. Sometimes it's a new form of communication or a never-before-seen mechanism of reproduction.

In biology, 'novel' usually refers to something that is new, unique, or previously unknown in a particular context or field of study.

The origin story is significant as it gives the starting point. It helps us understand how life forms evolved. For example, knowing how the first multicellular organisms emerged is key in biology.

It can expand our perspective. For example, when we see bio - engineered creatures in science fiction, it makes us think about the possibilities and ethics of genetic engineering in real life. The idea of cloning, which is often explored in science fiction, has led to more discussions about its real - world implications.
