What are homologous chromosomes?

Biology
1 answer:
Leto [7]3 years ago
6 0

Answer:

The correct answer is a. chromosomes that are similar in their size, shape, and gene content.

Explanation:

A homologous chromosome is the chromosome which is similar in shape, size, centromere position and they contain the same genes at the same locus also.  

One homologous chromosome comes from the father and the other homologous chromosomes come from the mother. These chromosomes have the same gene at the same locus but the alleles of that gene can be different in homologous chromosomes.  

The homologous chromosome separates during the meiosis so that the gamete has half the number of chromosomes. So the correct answer is a.

Explain why athletes who excel at short sprints probably have fewer slow oxidative fibers in their leg muscles.
Elza [17]

Answer:

Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.

Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.

Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.

Explanation:

Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.

Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.

New membrane phospholipids are synthesized by enzymes bound to the _____________ side of the _________________ membrane. a. lumi
JulsSmile [24]

Answer:

The correct option is C) cytosolic, endoplasmic reticulum

<em>New membrane phospholipids are synthesized by enzymes bound to the cytosolic side of the endoplasmic reticulum membrane.  </em>

Explanation:

Synthesis of proteins that are destined to membrane or exportation starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence is located in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle. This particle joins the signal sequence of the protein and leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building. When they reach the membrane of the endoplasmic reticulum, the signal recognizing particle links to a receptor associated with a pore. Meanwhile, the ribosome keeps synthesizing the protein, and the enlarged polypeptide chain goes forward the reticulum lumen through the pore. While this is happening, another enzyme cuts the signal sequence, an action that requires energy from the ATP hydrolysis. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen. Here it also happens the protein folding (which is possible by the formation of disulfide bridges of proteins are formed) and the initial stages of glycosylation (the oligosaccharide addition).  The newly synthesized proteins get packaged into vesicles that take them to the Golgi apparatus.

In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids. Once these processes are done, the glycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
