The given image is a neuron. Neurons are present in the nervous system. The part which is labelled as 4 in the diagram is myelin sheath. Thus, the correct option is D.
What is a Nerve cell?A nerve cell is a specialized cell which makes the nervous system. This system is responsible for the control of functions in an organism. Neuron (nerve cell) are the basic units of the nervous system.
A nerve cell consists of three parts- the cell body, a major branching fiber which is an axon and smaller branching fibers known as dendrites. The axon has nodes of Ranvier and myelin sheath. The nodes of Ranvier are the gaps which are present in the myelin sheath that coats the neural axon. The myelin sheath permits electrical impulse to move down the axon in a neuron. The nodes of Ranvier allow movement of ions in and out of the neuron that helps in propagation of electrical signals down the axon of the nerve cell.
Therefore, the correct option is D.

A chromosome’s structure is what it is made of and how it is organized. Its function is what it does. How does knowing about the structure and function of chromosomes help to explain variation in sexually reproducing organisms?
Answers
Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.

What kind of joint allows the arm to bend?
Cartilaginous
Suture
Fibrous
Synovial
Answers
Answer:
Hey there!
The correct answer would be Synovial. A synovial joint allows the arm to bend.
The synovial (or joint) cavity is this area, and synovial fluid is what fills it. By lubricating the joint and minimizing friction between the bones, synovial fluid enables better joint movement. Thus option D is correct.
What main role of Synovial joint in bend?Keeping the articulating bones of the joint cavity from rubbing against one another is the synovial joint's main function. All synovial joints are diarthroses, but the range of motion differs between different subtypes and is frequently constrained by the ligaments that hold the bones together.
Bones may move freely thanks to movable joints. Synovial joints are all joints that may move. They also encompass the elbow, hip, and shoulder in addition to the knee. The most prevalent type of joints in the body are those that can move.
Therefore, Synovial kind of joint allows the arm to bend.

Answers
Answer:
the last phosphate bond is broken
Explanation:
ATP, is a chemical molecule with the name, Adenosine triphosphate. It is the energy currency of a living cell usd to drive many cellular processes in the body. ATP is produced during the process of cellular respiration.
Adenosine triphosphate (ATP) has an Adenosine molecule (Adenine base and a ribose sugar) and three phosphate groups. However, the energy in ATP is harnessed for utilization when the bond that binds the third phosphate group is broken.
The breaking of the last phosphate bond releases a phosphate group and an Adenosine diphosphate (ADP) molecule.

When people have their gallbladders removed, their bodies no longer have a place to store bile, and the bile flows from the liver continuously. What effect might this have on their ability to digest fats?
A. There will be very little change since bile will still be present to emulsify fats.
B. Fats will be emulsified more efficiently with the constant flow of digestive enzymes.
C. It will be unlikely that they will be able to emulsify and digest fats.
D. Only small amounts of fats will get digested since high concentrations of bile enzymes are needed for efficient digestion.
Answers
Answer:
A. There will be very little change since bile will still be present to emulsify fats.
Explanation:
The gallbladder is a pear-shaped storage sac present in the alimentary canal of humans and functions to store excess bile in between meals. The bile is a greenish-yellow substance composed of different substances like salts, bile pigments, cholesterol etc. The bile is produced in the liver and aids in the digestion of fats.
The gallbladder serves as an intermediary between the organ of bile production (liver) and its destination (intestine). According to the question, once the gallbladder is removed, there is no longer a place to store bile. However, bile will still be produced by the liver and released directly into the intestine instead.
Hence, the bile will still be present to perform its function of emulsifying fats with little changes in the way it is released into the intestine. Note that, the gallbladder only regulates the speed at which the bile is released into the intestine.

Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates.
Order: 1000 mL of D51/2NS (dextrose 5% in 0.45% sodium chloride) in 8 hours
Available: 1 liter of D51/2NS (dextrose 5% in 0.45% sodium chloride); IV macrodrip tubing 10 gtt per milliliter
The patient should receive ______ gtt per minute.
Answers
Answer:
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number
Explanation:
To calculate IV flow rate or the drops per minute, the drop factor is needed.
The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package.
The formula for calculating the IV flow rate (drip rate) is given as;
IV flow rate (ggt/min) = {total volume (mL) / time (min)} * drop factor (gtts/mL)
From the given values in the question, drop factor = 10 ggt/mL; time in minutes = 8 hours * 60 minutes/hour = 480 minutes; volume of IV fliud = 1 litre = 1000 mL
Therefore, IV flow rate (ggt/min) = (1000/480) * 10 = 20.33
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number

O D. Fructose molecules will diffuse out of the cell.
Answers
If the amount of fructose is more outside the cell than inside the cell, then fructose molecules will move into the cell through diffusion. The correct option is A.
What is osmosis?Diffusion is the movement of substances from a region of higher concentration to a lower concentration region. A gradient in Gibbs free energy or chemical potential aids in diffusion.
In the given scenario, as fructose molecule is in excess outside the cell and is less inside, then the fructose molecule will cross the membrane from outside the cell to inside due to this concentration gradient.
Thus, the correct option is A.

The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answers
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.

Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
