In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.
I believe it results to a conformation change that moves the Na+ binding site to the inside of the cell. ATP hydrolysis involves the release of chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate.For example in muscles. The process of moving sodium and potassium ions across the cell membrane is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na+/K+ ATPase.
Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
Because you have to have fossil to make the evolution and it will make it better
