: Explain the relationship between well-being: self serving bias, self-esteem, locus of control, self-actualization, and recipro
zloy xaker [14]

Answer:

In humans, there is a readiness to perceive ourselves on priority and favorably. This is one of the reasons that helps in increasing the remembering memories of events that are favorable to the individual which results in benefits, it is known as self-serving bias.

Self-esteem is something that helps in knowing the self-worth and the importance of happiness of one's own. Being aware of environmental control result in achieving better in life and experienced less stress.  The potential use of the capabilities of individuals results in increasing awareness about what is the purpose of the life of an individual.

In order to make a protein the messenge on DNA must be converted to what?
Soloha48 [4]

Explanation:

-mRNA or messenger RNA

DNA wound into chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand.

Further Explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

  • Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.  

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

Which of the following is a site for a muscle or ligament attachment?
nexus9112 [7]

Answer:

Trochanter

Explanation:

All of these choices are colletively known as bone markings.

Trochanter is an example of a site for a muscle or ligament attachment. We have two trochanters, the greater trochanter and the lesser trochanter. You can find these in the femur, or the thighbone. These are points where the muscle of the hips and the muscle of the thighs are attached.

Eliminating the rest:

Sinus is a cavity or a sac of air, common in the cranium (skull).

Fossa is a depression on the bone.

Foramen is an openning in the bone. You can see this in the vertebral column. There's a space or hollow area in the vertebrae where the spine runs through.

Groove is a furrow or a line that runs along the bone. It is gives space for a blood vessel to fit in so it won't get compressed by the muscles around it.

Which organism forms a dorsal nerve cord in its embryonic stage?
tester [92]

Answer:The correct answer is chordates

Explanation:

Organism in the phylum Chordata develop dorsal nerve cord in their embryonic stage. Development of dorsal nerve cord is the characteristic feature of these animals and is developed by the mesoderm layer. In many of them they are only present in embryonic stage.

In vertebrates notocord disappears after completion of embryonic stage and is replaced by vertebral column which provide support and anchor to the  body structure of vertebrates.

Tunicates  are chordates and have dorsal nerve cord only in prenatal stage and it disappears in adults.
