A gene is defined as : ( D ) A section of DNA that codes for a specific trait
A gene is a unit of heredity that is found in the DNA of an organism. gene occupies a specific part of the DNA and carries specific trait which is transferred from parents to their offspring across generations.
Genes are made up of nucleotides that are responsible for an organism's possession of certain characteristics or abilities through the coding of certain proteins.
Hence we can conclude that a gene is defined as A section of DNA that codes for a specific trait.

A. True
B. False
Answer:
81
Explanation:
the answer will be 319
B.) multiple alleles are available for the one chromosomal locus that governs skin color.
C.) the environment affected the phenotype that developed.
D.) polygenic inheritance.
Answer:
D.) polygenic inheritance.
Explanation:
Polygenic inheritance is a mode of inheritance wherein the single genetic trait is regulated by more than one gene. Here, the final phenotype of the individual depends on the sum total of the dominant alleles of all the genes involved in the regulation of that trait.
In the given example, a couple of mixed ancestries might have different genes in their genome for skin color. A combination of alleles of these genes in the progeny would produce new skin color which is not present in the parents. For example, a child with all the recessive alleles of the genes for melanin production would have very light skin color while a child with more dominant alleles would have darker skin.
The correct answer is B. Hydrosphere, geosphere and biosphere.
Explanation
The hydrosphere is the system composed of all the water of the earth, mainly in liquid and solid-state. The biosphere is the terrestrial system composed of living beings its relationship with planet earth. The geosphere is the system that composes the earth and is divided into 3 layers, nucleus, mantle and bark; in it, the origin of terrestrial phenomena such as earthquakes, volcanism, and mountain formation occurs.
According to the above, when we take as reference the initial sentence "a volcanic eruption takes place under the ocean, Huge waves crash against the shores and destroy houses of people." A volcanic eruption occurs in the geosphere; the huge swell forms in the hydrosphere; Finally, the destruction of people's homes has to do with the biosphere. Then, the correct answer is B. Hydrosphere, geosphere and biosphere.
Answer:
Alanine
Explanation:
The nutritional monomer that can be transported in the blood is C. Alanine.
Sucrose and maltose are disaccharides made up of two sugar molecules and are not transported directly in the blood. Dipeptides are formed by the combination of two amino acids, and they are typically broken down into individual amino acids before being absorbed into the bloodstream. Alanine, on the other hand, is an amino acid and can be transported in the blood as part of the body's protein metabolism.
Answer:
The nutritional monomer that can be transported in the blood is option C: Alanine. Alanine is an amino acid, which is a monomer of proteins. Amino acids can be transported in the blood to be used for various cellular functions and protein synthesis.
