An individual's complete collection of genes is called his or her:
BabaBlast [244]

The right answer is genotype.

The genotype is the information carried by the genome of an organism, contained in each cell in the form of deoxyribonucleic acid DNA. Carried by the chromosomes, it is located inside the nucleus in eukaryotes and in cytoplasm in prokaryotes.

In humans, it is estimated that the number of genes is between 25,000 and 30,000.

Continental drift states that continents moved ____ to their current location
Ahat [919]
<h3>Slowly</h3>

Wegener proposed the hypothesis of continental drift, which suggested that continents are in constant motion on the surface of Earth. Over time Pangaea began breaking apart, and the continents slowly moved to their present positions.

<h3>What is Continental Drift ?</h3>

The theory of continental drift is most associated with the scientist Alfred Wegener.

  • Wegener's continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.

  • The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.

Explain how the resting potential is created and maintained. (sodium potassium pump) What happens when sodium comes in and potas
MAVERICK [17]

Answer:

The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.

Explanation:

The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.

When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.
