Answer:
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
A haplotype is a group of genes within an organism that was inherited together from a single parent. The word "haplotype" is derived from the word "haploid," which describes cells with only one set of chromosomes, and from the word "genotype," which refers to the genetic makeup of an organism.
Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair color, skin color or even the shape of our faces.
The typical metazoan mitochondrial DNA (mtDNA) is a double-stranded circular DNA molecule, which encodes a conserved set of 37 genes, including 13 protein-coding genes (PCGs) plus the two ribosomal RNA (rRNA) genes and 22 transfer RNA (tRNA) genes.
This, together with other special characteristics such as faster evolutionary rates than nuclear genes, presumed maternal inheritance, and absence of recombination makes mitochondrial DNAs one of the most popular targets for population genetics studies and accurate identification.
Answer:
The burning of wood and the burning of food calories produce carbon dioxide and heat. The calory burning gives energy to the body but in wood burning only wood becomes a carbon compound i.e. ash.
Explanation:
The burning of wood and the burning of calories release carbon dioxide and heat. In the body, oxygen breaks down the food calories and produces CO2 which release from the body by exhalation. The heat produced by food burning causes sweating. Oxygen also helps in burning of wood. In this way the food calory burning and wood burning are similar.
In calory burning the complex food becomes simpler and helps in tissue metabolism. In wood burning atmospheric oxygen helps in burning, and they release other gases like carbon monoxide, nitrogen to the environment which is not happening in case of metabolism. The complete burning of wood results in carbon compounds. In calories burning excess energy is stored in the form of fat. Because food calories are nothing but energy derive from different food.
The right answer for the first gap is monomer.
The right answer for the second gap is polymer.
The polymer is a large molecule consisting of basic units called monomers (or monomer units) connected by covalent bonds.
A monomer is a compound of simple molecules that can react with other monomers to give a polymer.
Answer:
Producers obtain energy from sunlight, consumers obtain energy from producers, and decomposers obtain their energy from dead living beings.
Explanation:
Producers produce their food by themselves as they are autotrophic. They obtain mostly their food and energy from the light energy comes from the sun, by the process of photosynthesis.
Consumers are depending on producers for their energy and food. They get energy from producers they eat as food and convert energy from it.
Decomposers get their food or energy by decaying dead living beings or other organic matter. They change these organic matter to energy.
