Answer: Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
New Zealand mud snails reproduce through asexual and sexual modes of reproduction. Asexual reproduction allows these organisms to reproduce more number of offsprings. Asexual reproduction advantageous as these organisms faces natural disaster conditions like tide, drought results in the decrease in the population. Therefore, does not get mate to undergo sexual reproduction. Sexual reproduction in these snails results in genetic variation in offsprings. Sexual reproduction results in increase in mutation rate in the genetic material being passed to offsprings because of resorting of genetic material being distributed from parent to offspring. This will result in genetic variations. Hence, parent will be different from offsprings. In asexual reproduction offsprings are the clones of parents as there is no resorting of genetic material takes place.
Answer:
1.) Compounds that contain a fused ring systerm are called _steroids_. These have three 6-membered rings and one 5-membered ring. some of these compounds are found in biological membranes.
2.) _Fatty acids__ are the building blocks for many lipids, and they generally contain an even number of carbon atoms and an unbranched hydrocarbon chain
3.) _Glycolipid__ are formed when a carbohydrate is glycosidically linked to a hydroxyl group of a lipid. examples include gangliosides and cerebrosides. these are also found in biological membranes.
4.) _Triacylglycerols_are the storage form of lipids, accumulating in adipose tissue, and they can be used as metabloic fuel. these compounds have a polar part, made of three ester groups, and a nonpolar fatty acid tail.
5.) _Sphingolipids__ are made up of a long-chain amino alcohol joined, either by a glycosidic linkage or a phosphodiester linkage, to a fatty acid. these do not contain _glycerol__. they are abundant in the nervous system.
6.) When glycerol esterified to two fatty acids and a phophoric acid molecule a _glycerophospholipid_ is formed. These are found in biological membranes.
Answer:
C
Explanation:
The rough endoplasmic reticulum contains ribosomes that synthesize proteins then transports them.
Answer:
Soil is the basic requirement for any plant or microorganism(that lives on land) to grow and get all the required amount of nutrients from the environment. Because, when a seed is planted inside a specific amount of soil it grows and develop in to a bud having its initial structure well set for having roots at one end and stem at the other, however the soil provides the bud the main protection and support which is required to balance its structure in a proper way or orientation.
As, there are different layers of soil and each layers consists of a different level or amount of components in it and provides different specification to the over all development of plant life.
Explanation:
- Along, with that there are different level of nutrients inside the different samples of soil taken from various regions or areas which makes it more different in nature to support life and give it a chance to grow or develop itself in it. As different species of plant life requires a more different form minerals and constituents to grow in which brings diversity among plant life, as not all of them requires the same sample of soil to grow in.
- Having, the specific structure of molecules in it, the soil also acts as a barrier for the plant life to save it self from any foreign object or pathogen.
