How can the absence of wolves affect elk population

Elk would overpopulate because no wolves are eating them and the food web would change because of the wolves not eating the elk.

An absence of the wolf predator to prey on the elk would cause the elk population to increase dramatically, as there would no be longer the threat of wolves to the elk. This would lead to an overpopulation of elk. Once the elk population increased severely, the elk would start to die out due to insufficient sustenance available to sustain all the elk.

Even though it may seem that the absence of wolves is better for the elk population's survival, in actuality, the wolves keep the elk population in check, and ensure their population doesn't grow too big for their environment to sustain.

What is the function of the Articular cartilage.
Morgarella [4.7K]

Answer:

Articular cartilage is a thin layer of specialized connective tissue with unique viscoelastic properties. Its principal function is to provide a smooth, lubricated surface for low friction articulation and to facilitate the transmission of loads to the underlying subchondral bone.

How do doctors and researchers decide whether a disease is a good candidate for gene therapy? what are the advantages and disadv
gladu [14]

Diseases that are best candidates for gene therapy are those whose disorder has been identified to be a malfunctioning gene and the biology of the gene is well known.  Gene therapy is also viable where the proper gene can be correctly delivered and replace the malfunctioned one.

The advantage of using viruses in gene theory is their effectiveness in delivering the desired gene by tapping into their natural mechanisms of infection.  However, disadvantages include the risks of affecting healthy cells while targeting sick cells and wrong placement of the desired gene hence causing undesirable mutations in DNA.

One factor is the length of the DNA that is required to be replaced through gene therapy. Most vectors have a maximum length of DNA that they can carry for effective transduction.  Another is the range of cell types that the vector can infect and the risk of immune response/ allergic reaction/ side effects.

The best vectors are herpes or vaccinia viruses.  The viruses are able to infect non-dividing cells such as the nerve cell. The vectors can accommodate 8400 bp in their genome and the transgene expressions have the potential to last long.

Traditional gene editing techniques such as TALENS and ZFN use modular proteins that target nucleotide sequences. In the CRISPR tool, the Cas9 protein is steered by a guide RNA (which is a complementary sequence to the target sequence) to the target region.

<span>One ethical issue of gene editing is its use in genetic enhancement to develop ‘designer babies’.  The question of who should decide on whether a trait is bad or good also complicates this matter. The morality of artificiality enhancing attributes such as strength, athletic capability, intelligence, and etcetera could lead to an unhealthy ‘arms race’  between humans. </span>

In sports doping, gene editing could be used to enhance genes that enhance muscle strength by targeting myostatin (MSTN) and GF-1 genes. Genes that promote quick break down of lactic acid and increases oxygen capacity of the lungs and blood such as EPO gene could be targets of sports doping.

<span>Gene editing will treat diseases and disorders by repairing the causative defective gene. This is already applicable in cystic fibrosis. Artificial gene selection will be common in future thanks to gene editing.  Future humans will, therefore, have ‘desirable traits’  or new traits depending on what is appealing to the society. </span>
