Answer:
Sodium and lithium are in the same group of the periodic table; this is because they both have the same number of electrons in their outer shell (1 as indicted by the group number). this commonality is the reason they have similar chemical properties. As we go down the group however, the electronic structure of atoms of an element changes as that there are a increasing numbers of ‘shells’.
Electron ‘shells’ are filled according to ruled of quantum mechanics however to simplify things in this case the first shell can fit 2 electron, the second 8, and the third shell 8. Lithium has 3 electrons, hence it the first shell is filled, and 1 electron occupies the second shell. Whilst Sodium has 11 electrons, hence its first two shells are filled and the third shell is occupied by one electron.
To expand on this question, the duet/octet rule is a rule in quantum mechanics that observes that main group elements tend to be stable with a full outer shell.
This explains why sodium and lithium is found in the form of Li+ and Na+ ions in nature.

Answer:
The right answer is speed the recycling of nutrients.
Explanation:
Saprophytes are living organisms that live and take their nutrition from dead and dead organisms. They break down the complex organic matter into simpler substances which is then taken up by the plans to conducting numerous metabolic activities.
<span>During the development of
a gamete, the two alleles of the P generation separate. Each gamete carries one allele from each
parent which randomly pairs in the F1 generation. This mechanism repeats when
F1 plants cross and yield F2 plants. The
outcome of the F2 generation would then have new combinations of alleles which
can be different compared to the preceding generations.</span>

The phenotype of an organism is a collection of its observable traits or characteristics. The term describes the physical form and structure of an organism as well as its physiological and biochemical traits, behavior, and results of that behavior. The blood clots incorrectly as a result of hemophilia, a genetic bleeding disorder. Both spontaneous bleeding and bleeding after an injury or surgery may result from this. Numerous clotting proteins found in blood can help to stop bleeding. Blood clotting is impaired by a rare disorder called hemophilia. It happens as a result of the body not producing enough of a protein called a clotting factor. Clotting aids in stopping the bleeding after an injury or accident. In the absence of coagulation, bleeding may be excessively simple or prolonged. There is currently no known cure for hemophilia, despite the fact that treatment for those with the condition has significantly improved over the past few decades.
