Answer: Peptide bond
Explanation: A peptide bond is a type covalent bond that joins two amino acid molecules. It is formed by the removal of elements of water from a carboxyl group of one amino acid and an amino group of another amino acid. It is a condensation reaction that results in the formation of dipeptide molecule. Three amino acids can be joined by a peptide bond to form a tripeptide.
Changes in mitosis, crossing over, random fertilization and random arrangement in meiosis.
<u>Explanation:</u>
Genetic diversity of sexually reproducing organisms are controlled by many factors and they are - changes in mitosis, crossing over, random fertilization and random arrangement in meiosis.
During crossing over, the sister chromatids of homologous chromosome crossover and exchange their genes which leads to recombination eventually causing genetic diversity.
Random fertilization of male and female gametes leads to the formation of zygote having the genetic content of both maternal and paternal gametes causing variation.
Environmental factors also causes some change in with time.
A sugar (called deoxyribose)
A Phosphate (1 phosphorus atom joined to 4 oxygen atoms)
One of 4 bases (Adenine, Guanine, Cytosine, Thymine)
Answer:
Explanation:
I'm not sure what the multiple-choice answers are but knowing that: abiotic factors are non-living chemical and physical parts of the environment that affect living organisms. But if there is any answers related to the cockroaches environment like Temperature and climate those may be the best choices.
