What percent of potassium-40 remains undecayed in a rock that is 3.9 billion years old? The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.
Answer:
The correct answer is - Venom enzyme inhibitors.
Explanation:
The snake venoms are the complex mixtures of phospholipase A2s, disintegrins, serine proteases, C-lectins, and metalloproteases, and others. The snake venom phospholipase A2s (svPLA2s) enzymes found in most of the families of venomous snakes that cause anticoagulant effects, cardiotoxicity, neurotoxicity, and cytotoxicity, and other effects.
In antivenom, there are Venom enzyme inhibitors other than antibodies that help in neutralizing these enzymes by weakening or inhibiting these toxic actions.
Answer:
Cell
Explanation:
Cell the essential membrane- bound unit that contains the key particles of life and of which every living thing are formed.
These cells collaborate with other specific cells and become the structure squares of huge multi cell living beings, for example, people and different creatures.
The levels of organization range from a single organelle all the way up to a highly structured hierarchy.cell governs all physical and chemical process in life.
Answer:the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
