Why is articular cartilage necessary for long bones?.
MariettaO [177]

Answer:

Articular articular cartilage is very important part of the long bone structure. It is present between the bones at the joints and help in reducing the friction between the joints. the epiphytes is data present at the end of the long bones are usually have a covering of the articular cartilage and it has a very thin layer of cartilage that helps in reducing the friction .

It also act as a shock absorber between the two bones and helps in the transmission of force from one phone to another and divide the force across the skeletal system. It also transmit the force on the bones with low fictional coefficient. The articular cartilage are very susceptible and prone to the injury and it lacks blood vessels and nerves. Articular cartilage is made up of hyaline cartilage and is made up of densely packed extracellular matrix which certain type of specialised cells known as chondrocytes. It is also made up of water , collagen , proteoglycans and glycoproteins .

Abnormal chromosomes are frequently found in malignant tumors. Errors such as translocations may place a gene in close proximity
mihalych1998 [28]

Answer:

B) expression of inappropriate gene products

Explanation:

Most of the cancers are caused when a normal gene that code for one or other proteins involved in the regulation of the cell cycle is mutated. The mutated gene may cause the production of the faulty gene products. For example, the overproduction of products of the protooncogene that push cells through the cell cycle leads to tumor formation. Likewise, when the tumor suppressor genes are not able to produce enough product to prevent progression through the cell cycle, cancer may develop.

One of the traits that we looked at in class was a widow's peak (has peak is dominant, no peak is recessive). For each individua
Marina CMI [18]

Answer:

Explanation: 1) Individual who is bald but neither parents has a widow's peak: As having a peak is dominant and the individual is bald with parents that doesn't have the trait, the genotype is recessive, in the case ww;

2) Individual has a widow's peak: The individual's genotype can be WW, homozygous for the trait or Ww, heterozygous for the trait, depending on the genotype of the parents;

3) Individual can't roll their tongue: Being able to roll the tongue is a dominant characteristics, so if the individual can't roll their tongue means the genotype is recessive. But, there is little evidence that this trait is dominant or inheritable;

4) Individual has a widow's peak  but their mother does not: In this case, the genotype of the individual is heterozygous (Ww), because the mother is recessive (ww) and the offspring has the trait, so the father must have had it;

5) If an individual does not have a widow's peak (ww), which genotype would be impossible? If this individual crosses over with another individual with the same trait, their children will be all recessive for widow's peak (ww), so there is no possibility of an offspring with the trait;

If the initial individual crosses over with an individual with widow's peak, two possiblities can occur:

  • If the crossover is with an individual homozygous for the trait (WW): all their children will have widow's peak with genotype Ww. So, the possibility of not having the peak is 0;
  • If the crossover is with an individual heterozygous for the trait (Ww), there will be a probability of 25% for the children to have genotype WW, a probability of 50% for the offspring to be heterozygous (Ww) and has the trait and probability of 25% to be recessive (ww) and therefore doesn't have the trait;

Lipids form the membranes surrounding the cell and various internal compartments within an organism. Which property of lipids ma
chubhunter [2.5K]

Answer:

Hydrophobic Properties

Explanation:

Lipids and water do not mix. The contents of cells in the larger proportion is the cytoplasm, this is made up mostly of water. The lipids serve as a barrier; the contents that are distributed in a watery medium will not be able to mix. This is due to the hydro-phobic or water "hating" capacity of lipids.
