Cancer is characterized by uncontrolled cell growth and proliferation.
In a successful food web, the amount of primary producers (such as plants) is typically greater than the amount of herbivores, which in turn is greater than the amount of carnivores. This is because energy is lost at each trophic level, so fewer individuals higher up the food chain are supported by the energy available from the producers.
False. Biology is a dynamic and constantly evolving science that involves processes and interactions that can be complex and intricate. It often requires creative thinking and problem-solving skills to understand the diversity of life forms and their functions in various ecosystems.
False. While many skeletal muscles do work in antagonistic pairs (e.g. biceps and triceps), not all skeletal muscles function this way. Some skeletal muscles work alone or in synergy with other muscles to produce movement.
A hypothesis is defined as a statement that a researcher makes and believes to be true. It is a specific, testable prediction about what the researcher expects to find in a study.
True. Natural killer cells play a crucial role in immune surveillance by recognizing and eliminating cancerous cells, making them one of the body's important defenses against cancer. They can directly kill cancer cells and also produce cytokines to enhance the immune response against cancer.

No. Consider the statement "If I'm alive, then I'm not dead." That statement is true. The converse is "If I'm not dead, then I'm alive.", which is also true.
Proof by Converse is a logical fallacy where one asserts that if the converse of a statement is true, then the original statement must also be true. However, this is not always the case as the converse of a statement may not always hold true even if the original statement is true. It is important to avoid this error in logical reasoning.
a tautology is a statement that is always true. For example p or not p is always true because one of the two is always true.
Yes
A. The statement is true for mitosis and meiosis II. -sources mastering biology!
Yes, contrapositives are always true, as long as the original statement stood true.
