In a study that came out during early October scientists said that elephants may obtain a vital part of the puzzle in the fight against human cancer. Elephants rarely get cancer, which scientists have questioned for a very long time because elephants have 100 times the amount of cells as a...
Viruses possess simple protein structures, namely the spike, membrane, and envelope protein; therefore, when they enter living organisms (such as through the respiratory system), the viruses are easily transmitted. Once they have entered a host, the viruses duplicate exponentially and swarm the ...
Do all cells undergo mitosis? Cells: The smallest fundamental structural and functional constituents of living organisms that incorporate several structures or organelles within them are termed cells. Their abundance in an organism varies and they are competent to conduct imperative processes and functions...
Why do cancer cells break from host circadian rhythm? Insights from unicellular organismscancercircadian clockcyanobacteriaNADPHoxidative pentose phosphate shuntIt is not clear why cancer cells choose to disrupt their circadian clock rhythms, and whether such disruption governs a selective fitness and a ...
When John Todd was a child, he loved to explore the woods around his house,observing how nature solved problems.A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process ...
Parasitic organisms like drill worms will burrow through the hard shell of an oyster and trigger its mantle to secrete a barrier around the biological interloper. The resulting pearl is a foreign substance covered with layers of nacre. The size of a natural pearl can range from a scant 0.03 ...
Although antibiotics are not ‘cure-alls’ for all, they have become a worldwide medical standard for urinary tract infections. The antibiotic treatments also have many well-known drawbacks, such as: They kill both the unwanted micro-organisms and wanted micro-organisms. (Research has shown that...
s experiments have very little relevance for the question of free will. They do not relate to deliberative decisions at all, where readiness potential is not observed. Instead, they confirm, first, that neural activity in the brain is not completely deterministic and, second, that organismscan ...
Does cell signaling occur in all organisms? What two physiological characteristics are highly developed in neurons? Why do cells divide? What are the two types of synapses/neurons? Describe the differences between them. How do neurotransmitters help transmit impulses between neurons?
Even though the ability of invasion and metastasis are one of the hallmarks for cancer, these abilities are not unique to cancer cells as it can also occur during the early development stage of the embryo, in healthy organisms and in many noncancerous diseases (Mareel & Leroy 2003). ...
