Compaction of the soil is exacerbated by excessive grazing.

Julia made the following table to compare prokaryotic and eukaryotic cells. Structure Prokaryotic cell Eukaryotic cells Cell wall is present Yes Sometimes Flagellum for movement Yes No X is present Yes Yes Which of the following would best replace X? Cell membrane Mitochondria Nucleus Vacuole

Answers

Mitochondria ,Prokaryotes lack mitochondria and instead have their ATP on their cell surface membrane. The eukaryotic cells are typically larger than prokaryotes and more various in their shape and structure.

Is mitochondria absent in prokaryotic cells?

Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus whereas their genetic content is free-floating within the cell. They also lack the numerous membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.

Thus, option "B" is correct, Prokaryotes lack mitochondria and instead have their ATP on their cell surface membrane.

The stiff muscles (myotonia congenita) present in one of the patient's leg explains the difference between EMG recorded from the right and left leg.

What is EMG?

An EMG is an abbreviation for electromyography and it can be defined as a diagnostic test or procedure that is typically used to measure, assess and evaluate the health condition of muscles and the nerve cells (motor neurons) within the body of a living organism that controls them.

Based on the electromyography (EMG) test report, a pathological condition which explains the difference between EMG recorded from the right and left leg is as a result of the stiff muscles (myotonia congenita) present in one of the patient's leg.

In conclusion, electromyography (EMG) is primarily used to measure a burst of electrical activity across muscle membranes when they contract.

List and describe several ways in which a recessive trait might be eliminated from a family or population

Answers

A recessive trait is often depicted as a lowercase letter, while a dominant trait is depicted as a capital letter. So, aa has two recessive genes, AA has two dominant genes, and Aa has both a dominant and a recessive gene. To eliminate the recessive gene, it has to have less of a chance of survival than the dominant gene. After a lot of time, if the aa or Aa gene keeps mixing with either AA or Aa genes, eventually the recessive gene will go away, although it will take many generations.
