Why is protozoan not considered an animal cell? Why is cell division important for unicellular and multicellular organisms? How does water movement in and out of a cell differ between plants and animals? Why is the cell considered the fundamental unit of life?
Explain why the cell is an important basic unit of many pathological processes. Why an isolated cell does not undergo cell division whereas a bacterial cell does? Why is compartmentalization in eukaryotic cells important? Why is compartmenta...
Why is cell division so important? Why is cell division important for both unicellular and multicellular organisms? Why are cells so small? Why do cells spend most of their life in interphase? Why is it important that both animal and plant cells have a cell membrane? Explain what would happe...
Plants grow larger via cell division and cell elongation. Simple plant growth is facilitated by meristem tissue because it is the primary site of cell division (mitosis) in the plant. ... Becausethe source of all new cells in a plantis the meristem, this tissue plays an important role in ...
If you’re studying biology, you’ll likely learn about the cell theory. The cell theory is one of the most important tenets of biology, and practically everything else you learn in science class relates back to it.But what is the cell theory?In this guide, we’ll give you a clear ce...
Homeostasis is the body’s way of maintaining a steady balance in the internal organs regardless of fluctuations in the external environment. Homeostasis is an important function in all humans and animals as keeping a stable environment requires constant adjustments as the environment changes. Homeostasi...
Meiosis, the cell division process giving rise to sperm and eggs, involves several steps, one of which is the formation of a large protein structure called the synaptonemal complex. Like a bridge, the complex holds chromosome pairs in place enabling necessary genetic exchanges to occur that are ...
However, while providing ad libitum forage may seem to be the answer to a horse's various needs, it is not necessarily the best solution for all horses as it can compromise their body condition. Providing horses with ad libitum forage helps maintain an optimal gastric pH-level and prevents ...
2014). Among animals, most species exhibit genetic sex determination (GSD). GSD mechanisms themselves are diverse and include the male (XY/X0) and female (ZW/Z0) heterogametic, haplodiploid as well as the hermaphroditic systems that are common throughout the tree of life. In no clade is ...
The so-called cognitive revolution in the study of behaviour has undoubtedly greatly enriched the toolbox for understanding learning processes and is very well summarised by Shettleworth (2010). Immunological plasticity In the immune system of humans and vertebrate animals, molecular plasticity takes ...
