Answer:

b. Many mitochondrial proteins are coded by cellular nuclear DNA.

Explanation:

According to the concept of endosymbiosis, eukaryotic organelles such as mitochondria and chloroplasts arose from symbiotic relationships between larger cells and smaller prokaryotes. These smaller prokaryotes were incorporated and lived within them. According to this concept, mitochondria originated when a larger cell engulfed an aerobic bacteria (most probably the purple bacteria) that lived in it. However, some of the proteins of the mitochondria are encoded by nuclear chromosomes. This dependence of mitochondria on nuclear DNA does not support the concept of endosymbiosis.

Answer:

c. some mitochondrial proteins are not coded by cellular nuclear DNA

Explanation:

Symbiosis is a relation between two different species and they both get to benefit from each other. Endosymbiosis has occurred inside the host. Here one organism lives inside other like mitochondria and chloroplast are present in the animal, plants.  

When the mitochondrial DNA undergoes density gradient centrifugation, the satellites are separated. The density of the satellite is more so it is detached from DNA.  

As mitochondria have their DNA it has its ribosome to synthesis proteins. But most of the mitochondrial proteins are present in the cell cytoplasm and nucleus. So mitochondrial proteins are coded by cell nucleus.

Mitochondria is a double membrane structure and they are present in the cell by the endosymbiosis process. They more resemble bacteria. The mitochondrial protein is transmitted by the woman, not both parents. It is passed by single lineages.

Antibiotics kill certain bacteria but do not harm human cells. Explain.
Fantom [35]
Antibiotics typically work as competitive enzyme inhibitors, they bind to enzymes and prevent them for being able to caring out certain metabolic processes. Antibiotics will effect only certain types of enzymes and typically humans may not produce these enzymes meaning it won’t have an effect on our cells but will kill bacteria. The thing is though we have “good” bacteria in our body that is also killed by antibiotics which in turn cause problems with digestion and other bodily processes. If you want an example of what an antibiotic does, it will prevent an enzyme in the bacteria from producing a membrane and it becomes easier for our bodies to attack the cell, white blood cells have an easier time killing the cell after the enzyme is inhibited. Also this is not to say that all antibiotics don’t affect human cells they may affect them slightly but typically bacteria is what’s killed

Many mammals become ill if they drink milk as adults even though they could consume it as babies. What causes this digestive iss
Mnenie [13.5K]

Answer:

As mammals grow, they stop producing lactase.

Explanation:

Mammals consume their mother's milk during the first stage of life. Milk has a sugar called lactose. Lactose is a disaccharide formed by the union of one molecule of glucose and another of galactose. To absorb it our digestive system releases an enzyme (lactase) that breaks the union between galactose and glucose. As mammals grow, they stop producing this enzyme, which makes lactose indigestible. As a result, ingesting milk may cause  diarrhea, gas and bloating.

What type of transport occurs in the cell membrane when a person does sports and is consuming alcohol?
andreyandreev [35.5K]

Cellular transport: it is the exchange of substances through the plasma membrane, which is a semipermeable membrane. Transport routes are through the cell membrane

  • It allows the metabolism waste to be expelled from its interior
  • It allows the movement of substances that it synthesizes as hormones.
  • Metabolic energy: is the way in which it acquires nutrients through processes of incorporation into the cell of nutrients dissolved in water.

Therefore, when the person consumes alcohol in excess the ce transport is part of the disincorporation of toxic waste, while when the person does sports, and is supposed to have a balanced diet, the cellular transport uses it for his metabolic energy.
