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.
A) predators, like snakes
Eliminate
B) omnivores, like raccoons
C) more producers, like plants
D) small animals, like the opossum
Answer: The correct answer is-
A) predators, like snakes.
As per the information given in the question, there is plentiful wildlife in the pineywoods. It is inhabited by more than 100 species of birds and many small mammals such as cottontail rabbits and squirrels.
In order to keep balanced population in pineywoods habitat, it is required to include predators like snakes ( that capture and eat other organisms as source of energy such as birds, rats, and other small mammals) as they will prevent the organism from overcrowding in the habitat.
Thus, it will maintain a balanced population in the pineywoods.
Therefore, option A) is the right answer.
The anatomy, or structure, of an organ helps define its function. This can be seen at every biological level - from cells grouping together to form tissues, which combine to create organs, which work collectively within a system to support an organism's survival and growth. An example of this includes the human heart, whose specific muscular structure and internal composition allow it to efficiently pump blood.
The anatomy of an organ, or how it is structured, directly influences what functional roles it can undertake. From the cellular level, where cells initiate all physiological functions, to the tissue level, where a group of similar cells work together to perform a specific function, structure plays a vital role in function. Several tissues come together to form an organ, like the heart or stomach, which performs one or more specific physiological functions.
Take, for example, the human heart. Its robust muscular structure allows it to efficiently pump blood throughout the body. The internal anatomy, including the presence of four separate chambers, ensures that oxygenated and deoxygenated blood do not mix, providing an efficient system for oxygen distribution. To this end, the anatomy of an organ defines its function.
In essence, understanding the anatomy helps fully appreciate the interrelationships of body structures, how they work together to function a particular body region or a systemic anatomical like the muscular system which comprises all skeletal muscles in the body.
