Does all life need oxygen?

No. There was life before oxygen – plants. They need carbon dioxide, water, and sunlight. For plants, oxygen is a waste gas.

What does somatic mutation mean?

An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.

What is required for the maintenance of life?

water, food, oxygen, heat, and pressure.

What are requirements of organisms for life?

In order to survive, animals need air, water, food, and shelter (protection from predators and the environment); plants need air, water, nutrients, and light. Every organism has its own way of making sure its basic needs are met.

Will a somatic mutation affect the evolution of a population?

A mutation that occurs in body cells that are not passed along to subsequent generations is a somatic mutation. … Thus, all mutations that affect the fitness of future generations are agents of evolution. Mutations are essential to evolution.

What makes a thing living?

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.

What are 8 Characteristics of life?

Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.

What are the four main features of life?

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
