The correct option is (A) grows at its maximum per capita rate.

During exponential growth, a population always grows at its maximum per capita rate.

<h3>What is exponential growth?</h3>

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
Consider a population of mice that increases exponentially every year by a factor of two, starting with 2 in the first year and increasing to 4 in the second, 8 in the third, 16 in the fourth, and so on. In this example, the population is increasing by a factor of 2 year. If mice gave birth to four pups instead, you would then have 4, 16, 64, and 256.
Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative (which is raised to a power).

A client with cardiogenic shock weighs 220 lb and is receiving dopamine at the rate of 3 mcg/kg/minute. the solution strength av

lions [1.4K]

First, convert pounds to kg,

220 lb : X = 2.2 lb : 1 kg = 100 kg.

Next, calculate the dosage per minute,

3 mcg/kg/min x 100 kg = 300 mcg/min.

Now, Convert mcg/min to mcg/hour,

300 mcg/min x 60 min = 18,000 mcg/hour.

Convert mcg/hr to mg/hour, 18,000 mcg/hr = 18.0 mg/hour.

Calculate the rate,

400 mg : 250 ml = 18 mg : X ml 400X = 4500 X = 11.25 = 11.3 ml.

So, 18 mg/11.3 ml should be infused at 11.3 ml/hour

Which statement does not describe an organism that reproduces asexually?

antoniya [11.8K]

Answer: Male and female gametes are involved.

Explanation: Asexual reproduction is a type of reproduction in which one or more offspring is produced from a portion of a single parent without the involvement of the gametes or sex cells. It promotes rapid multiplication in many organisms and reduces the chances of introducing more variations into a population. Types of asexual reproduction include budding, fragmentation, spore formation and fission.

What is a mineral that is toxic to sheep

aleksklad [387]

Copper. Copper(Cu) is deadly to sheep because excess amounts of copper are concentrated in the liver rather than being excreted. Over time, this excess of Cu can destroy liver tissue, resulting in death of the animal.
