If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?
Chromosomes and genes do not double in each generation in se-xual reproduction because they are usually halved before being donated to offspring.
What is meiosis?Meiosis is a reductional division involving s-ex cells. Meiosis happens prior to se-xual reproduction.
In other words, the halving of chromosomes takes place during the formation of gametes. Thus, gametes usually carry half of the chromosome and only a copy of each gene of the parents.
When two gametes combine to result in a zygote, their chromosomes and genes also pair up to arrive at a normal number of chromosomes and genes.

d. psychodynamic
The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)
The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).Biological factors include both genetic and biochemical factors.According to this approach, both mind and body determine the health of the subject.Learn more in:

What is unusual about the peptide bond compared to the other covalent bonds that form the polypeptide backbone?
A) The side chains only face internally, excluding them from interacting with water.
B) The single bonds on either side of the peptide bond cannot rotate, making the peptide backbone very rigid.
C) There is an amino group on one end of the backbone and an aldehyde group on the other.
D) Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond.
Answer:
D
Explanation:
A peptide bond is also known as amide bond which is formed between two amino acid molecules. An amino acid contains two functional groups; a carboxylic acid group and an amino group. ... The resulting linkage between two amino acid molecules is called a covalent bond.
The unusual about peptide bond is ( D ); Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond
The polypeptide is the Non-R group of amino acids polymers that consists of
N-C-C-N-C-C-N , and the polypeptide backbone allows for the backbone to backbone hydrogen bonding and it acts as a contributor to the secondary structure of the protein.
also the linkage between amino acid molecules is called a covalent bond.
Hence the unusual about the peptide bond when compared to other covalent bonds that form the polypeptide backbone is Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond

What is habituation?habituation is a type of response where complete elimination of a particular response or zero frequency of occurrence occur.
If the stimulus continues for an additional number of trials, although no changes occur but the response will exhibit lower levels of recovery.
Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli
Habituation defines as the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.
