<span>The phospholipid bilayer is a thin polar membrane made of two layers of lipid molecules. ... Biological bilayers are usually composed of amphiphilicphospholipids that have a hydrophilic phosphate head and a hydrophobic tail consisting of two fatty acid chains.</span>
To be considered a living thing an organism must be able to - that the organism was composed of cells (either 1 or many)
<span>- that the organism had a genetic molecule and was able to evolve (DNA is the base-unit of evolution) </span>
- that the cell/s of the organism was/were enclosed by a cell membrane (life is self-contained)
<span>- that the organism was able to carry out its own, self-contained, biochemical reactions </span>
- that the organism was able to reproduce, grow and develop (pass its genetic molecule onto a future generation)
<span>- that the organism was able to respond to its environment (either from a sensory, neurological or evolutionary way)</span>
Let's see... radiation can cause mutation...that's all i can think of at the moment, sorry
Answer: A. Research into a phytochemical from a plant which might inhibit cancer development.
Explanation:
The chemoprevention is a process of utilization of chemical formulations such as medication, supplements and vitamins to the stop the growth of cancer cells. This is necessary and important for people which are at high risk of developing cancer.
The research for the phytochemical derived from the plants can be an example of chemoprevention as this will help in inhibiting the cancer development.
Answer:
The correct answer is option A) "All living organisms use energy".
Explanation:
Even though living being use different strategies to obtain energy, an unifying principle among them is that all living organisms use energy to live. Plant use photosynthesis, which allows them to use sunlight, carbon dioxide and water to obtain energy. This classifies plant as producers, whereas animals that consume plants are primary consumers, animals that consume the animals that consume plants are second consumers, and so on.
