Rainbow [258]2 years ago

Answer:

The fossil record supports a "biological" type of evidence.

Explanation:

<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>

When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.

<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.

The patient is receiving succinylcholine or commercially called anectine. 
Succinylcholine is a medication often used in the context of general anaesthesia and its main effect is general paralysis. The drug's mechanism of action includes the inhibition of the acetylcholine's action on skeletal muscles. This inhibition is caused by the binding of the drug on the nicotinic acetylcholine receptor and the depolarization of the muscle cell.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. de
Pie

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.

Escherichia coli has a doubling time of 30 minutes. If a culture has 10 E. coli cells at the beginning of log phase, how many E.
Nat2105 [25]

80 E. coli cells will be in the culture after two hours.

<h3>What is culture?</h3>

The development of the human, plant, or animal cells in a lab, as well as microorganisms like bacteria and yeast. Cell cultures can be used for research, medication testing, and infection diagnosis.

Primary (mortal) cultures and cultures of established (immortal) cell lines are the two main categories of cultures.

One of the most crucial methods in cellular and molecular biology is cell culture because it offers a platform for studying the biology, biochemistry, physiology, metabolism, and other aspects of both healthy and diseased cells.

A culture of 10 E. coli cells.

Incubation time = 2 hours = 120min

Doubling time = 30min (120/30 = 4)

So, 1 cell - 30min = 2 cells - 30min = 4 cells - 30min = 8 cells - 30min

Therefore, 8 ₓ 10  = 80cells of E. coli at the end of 2 hours of incubation time.
