Asexual reproduction involves only one parent and the offspring is identical to the parent. An example of an organism that reproduces asexually is Archaea or bacteria. Sexual reproduction involves two parents and the offspring's genes are equally contributed by each parent. An example of organisms that reproduce sexually are some land mammals. The chromosomes of a parent and offspring in asexual reproduction are identical and there is no difference in the chromosomes.
X-rays
used to measure bone density.
<u>Explanation</u>:
The bones density test measured by the X-rays, it measures the content of calcium and other bone minerals that are packed into the segment of bone. Most commonly used parts of bone for testing are spine, hip, occasionally and the forearm. It is generally done to know the chances of osteoporosis. More the bone minerals, more will be density. More density means the higher bone strength. Before the test, a person should avoid having calcium supplement.
Carcinogenic mutation is not inheritable as they are not genetic. For the offspring to inherit something, that thing should be rooted from the sperm and egg. Carcinogenic mutations are environmentally acquired that cannot be passed on through the reproduction and DNA.
Producers: living things that make their own food through a process called photosynthesis
Autotrophs: an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Heterotrophs: an organism deriving its nutritional requirements from complex organic substances.
Photo autotrophs: organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration.
