Answer:
The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
Explanation:
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.
Explanation:
Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
Answer:
<u>Priming</u> refers to the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response
Explanation:
Priming is an effect related to the reaction or response to a certain stimulus may be conditioned by another previous stimulus, which is unconscious, that is, it is to expose someone to a certain stimulus that, without that person being aware of this, it will influence the response to subsequent stimuli. This circumstance is known as priming, and it is a phenomenon related to implicit memory (type of memory that is unconscious and involuntary) and is the most common way to evaluate it. Repeat priming has been preferably studied until recently using verbal stimuli presented in a visual or auditory manner. Implicit memory has been evaluated through a series of tests consisting of word associations.
