We are given:
2 units of packed red blood cells infused over 1 hour each, so 1 unit per hour
1 unit is equivalent to 250 ml
10 gtt/mL
solve for the volume per unit time:
1 unit per hour / 1 unit /250 mL = 250 mL per hour
The flow rate in drops per minute is determined by:
- converting hours to minutes:
250 mL per hour * (1 hour / 60 minutes) =4.2 mL per minute
-multiplying gtt/ml to flow rate
4.2 mL/min * 10 gtt/mL = 42 gtt/minute
Therefore the final flow rate in drops per minute is 42 gtt per minute.<span />
Inter-neurons, also known as associative neurons, are housed entirely within the central nervous system. They have short dendrites and may have either a short or long axon.
Each neuron has three parts such as cell body, dendrites and a single axon. Inter-neurons are connected spinal motor and sensory neurons. Transferring signals between sensory and motor neurons, they also communicate with each other .
These inter-neurons are 20 billion in numbers and mostly found in the brain and spinal cord and within automatic ganglia. They make >99% of all neurons in the body. Relays signals between a sensory neurons and motor neurons.

Answer:
The trophic efficiency between the primary and the secondary produces is 18.064 %
Explanation:
The trophic efficiency is the ratio or the fraction obtained by dividing the energy used for growth at a trophc level by the level of energy supplied at the the next lower trophic level.
The given parameters are;
The energy produced by the bacteria (primary consumer) = 173,000 kJ/(m²/y)
The energy contained in the plankton = 28,000 kJ/(m²/y)
The energy contained in the shrimp = 3,100 kJ/(m²/y)
The energy contained in the herring = 150 kJ/(m²/y)
Therefore, we have;
Energy supplied at the primary trophic level = 173,000 kJ/(m²/y)
The energy used for growth (contained) in the secondary trophic level (secondary consumer) = 28,000 + 3,100 + 150 = 31,250 kJ/(m²/y)
Answer:
As Jane exercises her heart rate and breathing rate increase because he muscles are asking for more oxygen and get rid of more carbon dioxide. More blood is diverted towards the muscles as they need more oxygen for respiration. She needs to burn glucose with oxygen and water to produce energy so she can run. The way she can get this oxygen into her body is through her lungs. Where oxygen from the air diffuses into the blood and carbon dioxide diffuses out.
Answer:
Oral contraceptives inhibit the secretion of gonadotropins by inhibiting the secretion of GnRH through a negative feedback mechanism.
Explanation:
Most oral contraceptive pills have combined dosages of estrogen and progesterone or one of these hormones. The estrogen and progesterone are involved in negative feedback inhibition of gonadotropin-releasing hormone (GnRH). Presence of small dosages of estrogen and progesterone inhibit the secretion of GnRH and thereby, prevents the secretion of gonadotropins (LH and FSH).
FSH (Follicle-Stimulating Hormone) is required for maturation of follicles while LH (Luteinizing Hormone) is required for ovulation of mature follicle.
Hence, hormonal contraceptives prevent conception by preventing follicle development and ovulation due to the absence of gonadotropins (FSH and LH).
