How is the genetic code similar in early and modern forms of life?

Early forms of life are thought to have used RNA as their sole source of information before DNA existed. The endosymbiotic theory says that millions of years ago a multicellular(eukaryote) organism engulfed a single-celled(prokaryote) organism. Instead of killing the prokaryote, the eukaryote allowed it to remain and incorporated it into its own environment. It is hypothesized that this is the molecular basis for the existence of RNA in eukaryotes.
<span>DNA and RNA differ by one atom. Both eukaryotes and prokaryotes use the same genetic code, and it is repetative in both, to signal the construction of proteins.</span>

Utah's Great Salt Lake has an average salinity seven times higher than that of the oceans. Very few multicellular organisms live
nignag [31]

Answer:

actively pump water back into their cells to counter its loss due to osmosis

Explanation:

  • When an organism actively regulates the osmotic pressure of the bodily fluids present in the body in order to maintain homeostasis in the body then this is termed as osmoregulation.
  • Since, the Great salt lake in Utah has a lot of salt in it, the water content in the surroundings of the brine shrimp is much less and hence, the water will move out of the brine shrimp's body as osmosis causes the movement of the water from higher concentration of water to lower concentration of water.
  • However, movement of water out from shrimp's body would cause it to desiccate and hence, it must have an actively pumping system that pumps the water back into their cells in order to compensate for the water lost due to osmosis.

A 49-year-old client is admitted with a diagnosis of cervical cancer. as the nurse is obtaining her health history, she says, "i
blondinia [14]
The nurse would most likely disagree with the patient. Pap smear is a diagnostic test that screens pre-cancerous or cancerous cells on the cervix, which is the opening of the uterus. It is recommended for women starting from the age 21 to regularly undergo this test, especially when sexually active. For the 49 year-old patient, she needs to undergo Pap smear test every 3 to 5 years. The patient should note that this test is used to track any abnormal cells in the cervix. When they do, early treatment would still be done in the hospital before it becomes even more serious. Hence, whether the patient took Pap smear tests regularly, she would still need the help of the hospital to treat it. It would only differ in the time of admittance.

Can the environment and the heritage be used to describe evolution?
Mrac [35]

Answer:

Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.

Explanation:

  • As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well.
  • For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.
  • Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.
