What are structures that are capable of growth and metabolism that have been produced in the laboratory?
Protocells.
American biochemist Sidney Fox in 1992 showed how the first cells may have occured. Fox produced protocells by heating solutions of amino acids. A protocell is a large, ordered structure, enclosed by a membrane, that carries out some life activities, such as growth and division. The first forms of life may have been prokaryotic forms that evolved from a protocell.

What is liquefaction capable of doing to man made structures?
liquefying it
What is the only carbohydrate capable of directly producing energy by cellular respiration?
The only carbohydrate capable of directly producing energy by cellular respiration is glucose. This is a monosaccharide that contains six carbon molecules that is produced in plants through the process of photosynthesis and in animals it is produced by the metabolism of carbohydrates.
How are spores structurally different from seed?
Spores are single-celled reproductive structures produced by certain organisms like fungi, whereas seeds are multicellular structures produced by plants. Spores are smaller and more lightweight than seeds, and are often capable of surviving in adverse conditions for long periods of time. Additionally, spores do not contain an embryo like seeds do.
How did one-celled organisms form?
One-celled organisms are believed to have evolved from simpler molecules in the primitive Earth environment, eventually forming into structures capable of self-replication and metabolism. Over time, these structures evolved into more complex organisms through processes like natural selection and genetic mutations.
What are tiny cells from which some plants germinate?
Tiny cells from which some plants germinate are called spores. Spores are reproductive structures that are produced by certain plants, such as ferns and mosses, and are capable of developing into new plants under the right conditions.

Are cells that exit meiosis immediately capable of fertilization?
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis.

Definition of living things?
As science defines it, to be living, a thing must be capable of growth, reproduction and metabolism.
What is one similarity between seeds and spores?
They are both asexual means of reproduction.
What are protobionts?
Protobionts are aggregates of abiotically produced molecules. They are not capable of precise reproduction, but they maintain an internal chemical environment different from their surroundings and exhibit some of the properties associated with life, including metabolism and excitability.
What human body part that is capable of contracting?
Muscles are capable of contracting in the human body. This allows movement, support of body structures, and distribution of substances throughout the body.
Is monera aerobic or anaerobic?
Monera bacteria can be aerobic (requiring oxygen for metabolism) or anaerobic (able to thrive without oxygen). Some species are capable of both aerobic and anaerobic metabolism, depending on the environment they are in.
Why are the other 2 types of structures not weakened by lever action?
Other structures are not weakened by lever action because they are designed to resist the forces produced by the lever action. For example, arches and domes are capable of distributing loads evenly, resulting in a balanced force distribution that minimizes the impact of lever action. Additionally, truss structures can handle the loads imposed by lever action by efficiently transferring the forces through their network of interconnected members.
