What is the most challenging issue facing genome sequencing?
Stella [2.4K]

Answer:

the ethics of using information from genomes at the individual level

Explanation:

The human genome project (PGH) aims to identify all genes responsible for our normal and pathological characteristics. Long-term results will surely revolutionize medicine, especially in the area of prevention. Thousands of genes can be analyzed at the same time, and people will be able to know if they have an increased predisposition to certain diseases, such as diabetes, cancer, hypertension, or Alzheimer's disease, and treat themselves before symptoms appear.

Alongside these advances, numerous ethical issues are already being discussed and others will arise. These ethical issues are a major challenge to human genome sequencing, and among these issues, the ethics of using genome information at the individual level have been the most challenging.

r-ruslan [8.4K]

Answer:

mitochondria  

Explanation:

Mitochondria are organelles found in eukaryotic cells that are capable of generating the main part of the energy required for the cellular biochemical reactions. In addition, mitochondria are also involved in distinct biological functions including, among others, cell signaling, death, differentiation and growth. It is believed that mitochondria evolved from prokaryotic organisms which introduced inside others to form eukaryotic cells, this theory is known as the 'endosymbiotic theory'.

Aging effects all of the body's cells; and therefore, the basic building blocks of tissues. As your body ages, many tissues ____
Artyom0805 [142]
I believe the correct answer from the choices listed above is option B. Aging effects all of the body's cells; and therefore, the basic building blocks of tissues. As your body ages, many tissues lose mass resulting in atrophy. <span>Organ </span>Atrophy<span> is a decrease in the tissue mass of an organ due to either a decrease in size of individual cells (cellular </span>atrophy<span>). Hope this answers the question.</span>

All vertebrate embryos have _____ at some point during embryonic development, indicating a common evolutionary ancestor
aivan3 [116]

All chordates chare four structures. One of the is the tail. All vertebrate embryos have _<u>a tail</u>__ at some point during embryonic development, indicating a common evolutionary ancestor.

<h3>What is the relationship between chordates?</h3>

The evolutionary relationship between species is reflected in the similarities or differences in the patterns of embryonic development.

All chordates belong to the Chordata phylum, and share four main characteristics,

  1. Notochord, which is a precursor of the dorsal spine.
  2. Nerv cord, dorsally located and parallel to the notochord.
  3. Pharyngeal clefts
  4. Tail

All chordates express these structures at some point in their lives, especially in the early stages of embryogenesis. Many of them can be lost with animal development and become vestigial structures.

The tail is a vestigial structure in many vertebrates.

Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.

Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts

All vertebrates develop a tail at some point in their embryonic life, even humans. However, this structure lost its original function in several species, so after a period of embryogenesis, this tail disappears, and its forming vertebras get fussed with each other composing the coccyx.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, for instance, the coccyx has lost this function but is still an area of muscle insertion.

The correct option is Tail.

All vertebrate embryos have _<u>a </u><u>tail</u><u>_</u> at some point during embryonic development, indicating a common evolutionary ancestor.
