Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

1. What causes the inside of the cell to be more negative compared to the outside of the cell? Resting Potential, Action Potenti
sp2606 [1]

Answer:

Resting potential

Explanation:

This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.

List any two differences between distance and displacement..​
maw [93]
Distance is the length of the path travelled
displacement is the shortest length of the path travelled

distance does not have direction, hence, it is a scalar quantity
displacement has direction, hence, it is a vector quantity

If genetic drift is occurring you will be able to predict which allele will become more prevalent.
Blizzard [7]

Answer:

b. False

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. As happens at random, it is impossible to predict which allele will be prevalent in a population suffering from genetic drift.

Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent.

Thus limiting the genetic content of a particular group, restricted to the prevailing individuals. It is up to them, integration into another population, if an adaptation is maintained, or over time, from geographic and later reproductive isolation, constitution of a new species (principle of the founding species).

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals.

During evolution, a hypothesis concerning the decimation of dinosaurs, which occurred around 66 million years ago, establishes not only the end of these animals, but of various life forms (including plants), due to a huge asteroid that would have reached planet, raising a dense cloud of dust resulting from the collision, compromising photosynthetic processes (dependent on solar energy), as well as the respiration and nutrition of organisms.

BRAINLIESTTT ASAP!!!

Hi Geny!

Question - Describe the cell theory and the developments that led to the cell theory.

Answer:

There are 3 main components of cell theory:

  1. Each and every organism is wither unicellular or multicellular.
  2. The basic unit of life is the cell.
  3. Cells are created from cells that had existed previously.

There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.

  1. Mathia Schleiden discovered that plants were made of mainly cells.
  2. Rudolf Virchow discovered that cells are created from calls that had existed previously.
  3. Theodore Schwann discovered that animals were also made of mainly cells.

Hope This Helps :)
