If a student used a calibrated micrometer, which measures in ‘units’, to measure the length of a cell. Each unit is equal to 0.01 mm the student measured a cell as having a length of 5 units. The 5 units of measurement on a calibrated micrometer would be equal to 50 micrometers
What is a unit of measurement?
A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.
As given in the problem, a student used a calibrated micrometer, which measures in ‘units’, to measure the length of a cell. Each unit is equal to 0.01 mm the student measured a cell as having a length of 5 units.
The measurement of the one unit of the cell = 0.01 mm
The measurement of the five units of the cell = 5 × 0.01 mm
=0.05 mm
1 mm = 1000 micrometers
0.05 mm = 0.05 ×1000 micrometers
= 50 micrometers
Thus, the 5 units of measurement on a calibrated micrometer would be equal to 50 micrometers.

What type of channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters?.
Voltage-gated Ca²⁺ (calcium) channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters.
Voltage-gated calcium channels open in response to the wave of depolarization brought on by the action potential at the axon terminal. Neurotransmitter-containing synaptic vesicles undergo exocytosis when calcium reaches the axon terminal, releasing its contents into the synaptic cleft.
Action potentials are formed when a neuron gets stimulated causing a local depolarization in the cell membrane. This local depolarization triggers adjacent areas of the cell membrane to depolarize, and this continues creating a wave of depolarization traveling in one direction down the axon, called an action potential. As the action potential arrives at the axon terminal, specialized channels allow for the propagation of the action potential across the synaptic cleft to the adjacent neuron.

Which of the following describes and example of a positive feedback loop?
A. When we are kids, our heart rates are really slow and they just continue to get
faster and faster as we grow older. We are adding to the set amount every day.
B. During childbirth, females release oxytocin, a hormone that intensifies contractions. More contractions equals more oxytocin and this cycle continues until the child is born. The body adds more and more oxytocin.
C. When we eat a donut, our body works to add more and more sugar to our blood. We want to continue to increase the amount of sugar in our blood to stay
healthy
D. When we eat a donut, our body works to pull the sugar out of our blood to ensure we have the proper blood sugar levels. If we don't eat for awhile, our body works to add sugar from our reserves into our blood to ensure we have proper levels.

Which statement correctly compares nuclei acids and carbohydrates?
They both contain carbon, but only nucleic acids contain hydrogen.
They both contain carbon, hydrogen, and oxygen in a 1:2:1 ratio.
They both contain carbon, but only carbohydrates contain oxygen
They both contain carbon, but only nucleic acids contain phosphorous.
They both contain carbon but nucleic acids contain phosphorus. So, the correct option is D.
What are nucleic acids and carbohydrates?
Nucleic acid is a naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines).
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Carbohydrate is any member of a large and diverse family of naturally occurring organic molecules that include sugars, starch, and cellulose.
Monosaccharides (simple sugars such as glucose and fructose), disaccharides (2-unit sugars such as sucrose and lactose), oligosaccharides (3-10 or more sugars), and polysaccharides are the most prevalent types (large molecules with up to 10,000 monosaccharide units, including cellulose, starch, and glycogen).
Therefore the correct option is D.

How many moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2)?
180 moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2).
The reaction of denitrification is:2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O
From the above equation:2 moles of nitrate = 10 moles of electrons36 moles of nitrate = 36×2/10 = 180 moles of electronsNitrate and nitrite are converted to gaseous forms of nitrogen, mostly nitrous oxide (N2O) and nitrogen, through the microbial process of denitrification (N2). Numerous microorganisms have the ability to denitrify. When the oxygen (O2) level in their immediate environment changes, denitrification occurs.The entire conversion of nitrate to molecular nitrogen often involves a number of bacterial species, and more than one enzyme pathway has been found in the reduction process.Complete denitrification has an impact on the environment because nitric oxide and nitrous oxide, two intermediates in the process, are important greenhouse gases that combine with sunlight and ozone to form nitric acid, a component of acid rain.Therefore, the correct answer is 180 moles.

In the structure of the neuron, the __________ receives messages from other cells.
The correct answer is Dendrite.
A useful analogy is to think of neurons as trees. Neurons consist of three main parts: dendrites, axons, and cell bodies or cell bodies (see diagram below), which can be represented as branches, roots, and trunks of a tree, respectively. Dendrites (branch) are where neurons receive input from other cells. The dendrites branch like branches toward the tip and even have leaf-like structures called spines.
Axons (tree roots) are the starting structures of neurons. When a neuron wants to talk to another neuron, it sends an electrical message, called an action potential, across the axon. The cell body (tree trunk) contains the nucleus, houses the neuronal DNA, and makes proteins for transport down the axons and dendrites. Both the brain and spinal cord have different types of neurons. They are generally classified based on where they originate, what they project to, and what neurotransmitters they use.
