Select the best description of axon: a. stored in synaptic vesicles b. accumulates as yellow-brown granules as the cell ages c. contains a nucleus surrounded by cytoplasm receiving or input portion of a neuron d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Answer:
d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Explanation:
An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.
We have two types of axons in the body.
a. Myelinated axons
b. Unmyelinated axons.
The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.
The myelinated axons are very numerous and mush faster than the unmyelinated axon.

Answer:
b thick wall
Explanation:
a. hollow bridge.
b. thick wall.
c. plasma membrane.
d. plasmid replication.
An endospore may survive a drought because it is protected by a thick wall.
An endospore represents an extremely tough and dormant cell structure produced by some specific type of bacteria. The structures are resistant and primarily produced to ensure survival in the face of adverse environmental conditions.
Endospores are made up of the bacterial's DNA and ribosomes along with a large amount of a special type of acid that helps them to remain dormant - the dipicolinic acid. The entire structure is protected by a thick wall which contributes to their ability to survive tough environmental conditions.
The correct option is b.
Answer:
Thick wall
Explanation:
An endospore is a tough structure that is produced by some organisms like bacteria. It plays an important role in during environmental stress like drought, by enabling the survival of the bacterial cell during such stress and also making it highly resistant
A major feature of the endospore that aids resistance to environmental stress like drought is a thick wall called the cortex. This thick wall consists of specialized peptidoglycan, which makes the endospore highly resistant to highly resistant to high temperature.
What structure transports bile from the liver to the bile duct?
Answer:
Common Hepatic duct
Explanation:
Bile is a greenish thick fluid that consists of a mixture of substances like salts, acids, pigments, cholesterol etc. It plays a very important role in aiding digestion in the digestive system. Bile is produced by the liver, which secretes it through the common hepatic duct (collection of the right and left hepatic ducts).
The common hepatic ducts connect with the cystic duct (another duct that links to the gall bladder). This connection brings about the formation of the bile duct. Hence, the common hepatic duct conducts or transport the bile from the liver to the bile duct, which eventually empty its content (bile) into the small intestine or gall bladder.
The structure that transports bile from the liver to the bile duct is called the common hepatic duct.
Explanation:The structure responsible for transporting bile from the liver to the bile duct is indeed called the common hepatic duct. It is an important component of the biliary system, which plays a crucial role in the digestion of fats. The common hepatic duct originates within the liver and collects bile produced by hepatic cells.
It then joins with the cystic duct, which carries bile stored in the gallbladder, to form the common bile duct. Together, they transport bile into the small intestine, where it aids in the emulsification and digestion of dietary fats, facilitating their absorption in the digestive process.

What type of bacteria converts the ammonia and ammonium into nitrates and nitrites?
Bacteria converts the ammonia and ammonium into nitrates and nitrites is described below.
Explanation:
1. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants. Denitrifying bacteria converts nitrates back to nitrogen gas.
2. The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).
3. Nitrifying bacteria present in the soil convert ammonia into nitrite. Nitrite is then converted into nitrate. This process is called Nitrification.
4. De-Nitrification: Nitrogen in its nitrate form (NO3–) is converted back into atmospheric nitrogen gas (N2) by bacterial species such as Pseudomonas and Clostridium, usually in anaerobic conditions. These bacteria use nitrate as an electron acceptor instead of oxygen during respiration
Nitrifying bacteria are the type of bacteria that converts the ammonia and ammonium into nitrates and nitrites.
Nitrification is part of the so-called nitrogen cycle, which consists of several stages.
Nitrifying bacteria are:
Chemoautotrophic bacteria (they synthesize by themselves all the chemical components of their structures from simple chemical elements).Chemolithotrophic bacteria (they synthesize all chemical components of their structures from inorganic compounds, and obtain energy during this process).These bacteria are very abundant in nature, found in the soil, in lakes and in river currents with a high content of wastewater.
The ammonia in the soil from the urine of animals or from the action of fixing bacteria serves as food for other types of microorganisms, in this case nitrifying bacteria.These bacteria break down ammonia and oxidize it to nitrites (NO2–), and then the nitrites are oxidized to nitrates (NO3–).Therefore, we can conclude that nitrifying bacteria are the type of bacteria that converts the ammonia and ammonium into nitrates and nitrites.

A) D and E
B) A and D
C) A and C
D) B and D
Igneous rocks are the rocks that are the most resistant to weathering. In the diagram option A and C seems to be the most resistant to rock weathering.
What are rocks ?
These are the solid structures that are very hard in nature and it is very tough for us to break them as they are not at all brittle in nature.
Certain rocks that are very hard in nature and water can not penetrate them. The certain rocks orientations also depends upon whether the rock weathering takes place or not. In the effect of gravity, sediments deposit in horizontal layers.
The rocks which weathers the most are commonly found in horizontal direction because of water penetration in them directly because of the orientation in which they are arranged as per deposition.
Therefore, the basic concept that is applying here is just the orientation.

The fact that the zebra's stripes are passed down in its DNA indicates that the stripes may serve an evolutionary advantage. What do you think is the evolutionary need for such complex designs?
Answer:
Camouflage and other visual illusions
Explanation:
There are several theories for why zebras have evolved to have striped coats. One of the lines of thinking is that it allows them to blend into long grass to avoid predation. The stripes blend into a sort of gray colour at a distance, making them difficult to spot.
The stripes may also "dazzle" their predators, because the properties of black and white stripes can give the illusion of movement. If there are many zebra huddled together, some moving, some not, it may be difficult for a predator to lock on to its prey.
It could be some sort of deterrent to stop bugs and other pests, because they can less successfully land on striped patterns.
Answer:
Oftentimes, these exotic prints serve as camouflage so the animal can hide from predators. Sadly, such beautiful animals are also poached by hunters who use their furs for clothing and rugs, which has led to many of these wild animals becoming endangered.

Two rivers run into the ocean. One river is very long. The other is
very short. Which river probably drops the smallest rock pieces near the ocean?
Explain your answer.
Answer:
the very long river
Explanation:
Larger rocks tend to settle out of the water flow sooner than smaller rocks do, so the rocks remaining at the end of a very long river would tend to be very small. A very short river may still be carrying somewhat larger rocks.
The very long river probably drops the smallest rock pieces near the ocean.
_____
Perhaps the implied assumption here is that a very short river will have a higher gradient than a very long river. Another assumption is that rocks are picked up nearer the headwaters, and the gradient decreases with distance.
If both rivers end at a waterfall into the ocean, they may very well carry the same sort of rock size distribution. If the short river traverses muddy terrain, and the longer river traverses rocky terrain, the answer may be reversed.
In an experiment on the cell cycle, a researcher repeatedly injects a mouse with a variety of cyclin-dependent kinases, including mitosis-promoting factor (MPF). The compounds are delivered to the thyroid gland through a carrier complex in the blood. As the experiment continues, which change to the thyroid gland of the mouse is most likely to occur?
Answer:
A cancerous tumor will form in the thyroid
Explanation:
Cyclin-dependent kinases are proteinous in nature. They perform z series of biological activities in the body. They are responsible for controlling the cycle of a cell.
Cyclin-dependent kinases when they are mutated can cause the cells present in the human body to begin to multiply and divide uncontrollably thereby resulting in the formation of cancerous cells in the body.
This is why when a researcher repeatedly injects a mouse with a variety of cyclin-dependent kinases, including mitosis-promoting factor (MPF) and they are delivered to the thyroid gland by carrier complex in the blood, the cells in the thyroid would start to multiply uncontrollably thereby causing a cancerous tumor to be formed in the thyroid.

The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is?
A.) 0N
B.) 10N
C.) 1.2N
D.) 0.3N
E.) 2N
Answer:
0N
Explanation:
If an object is on one of these imaginary frictionless surfaces, the surface does not present any opposing force (frictional force) to slow an object sliding over it. Therefore no force is needed to keep the object moving.
The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is 0 N.
What is frictionless ice?
Two fundamental ideas related to the concept of force are established by the First Law. The "natural condition" of motion of all objects is not rest, as almost everyone would assume, but rather any constant velocity.
when they were finally given the freedom to act spontaneously, the velocity they had. In our daily lives, things frequently come to rest. Newton's insight that this was caused by the frictional force is what makes him so brilliant.
Objects float with whatever velocity they have from their prior interactions in space, far from the influences of gravity and air resistance, demonstrating the First Law.
Therefore, The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is 0 N.

Indentify the stages of the cell cycle using the drop down menus
Answer:
The stages of cell cycle are G1 phase, S phase (synthesis), G2 phase and M phase (mitosis and cytokinesis).
Explanation:
G1 phase is also called growth phase of the interphase. This phase occurs after the completion of M phase which consist of mitosis and cytokinesis and before the starting of DNA replication. S phase is a synthesis phase where DNA replication occurs. G2 phase is an important phase in which cell grow in size occurs and various proteins are produced which is necessary for the mitosis. After G1 phase, mitosis occurs in which a single is divided into two daughter cells having diploid chromosomes.
What effect might high temperature or irregular pH levels have on facilitated diffusion?
Answer:
The facilitated diffusion is a type of passive transport affected by different factors including the temperature and the pH level. The facilitated diffusion process is produced by proteins that enable the movement of molecules between both sides of the cell membrane.
The pH level depends on the ion gradient and this factor modifies the diffusion rate of the buffers between both sides of the cell membrane. Moreover, the temperature is a factor that modifies the ionic charge of molecules, as well as the structure and the porosity of pores that facilitate the interchange between both sides of the cell membrane
Antidiuretic hormone A) increases the permeability of the collecting ducts to water by increasing the number of aquaporins. B) is secreted in response to low potassium ion in the blood. C) causes the kidneys to produce a larger volume of very dilute urine. D) increases the permeability of the collecting ducts to water by decreasing the number of aquaporins. E) release is insensitive to the osmolarity of interstitial fluid.
Answer:
A) increases the permeability of the collecting ducts to water by increasing the number of aquaporins.
Explanation:
ADH is an hormone of the anterior pituitary gland concern with osmoregualtion. When the solute potential of the blood rises , with decrease in water potential , the water levels of the blood drops, the osmoreceptors in the hypothalamus sensed this from the circulatory blood and prompted the hypothalamus to stimulate the anterior pituitary gland to secrete ADH.
The hormone is carried in the circulating blood to the walls of the collecting ducts where it binds with the receptors on the walls of the tubule,which increases the fusing and binding of Aquaporins to the membrane of the collecting ducts to increase re absorption of water back into the blood, raising the water potential of the blood.
Answer:
The correct answer is option A) "increases the permeability of the collecting ducts to water by increasing the number of aquaporins".
Explanation:
Antidiuretic hormone, also known as Vasopressin, is a molecular messenger that stimulates water reabsorption in the kidneys. Antidiuretic hormone produce their effect by stimulating the synthesis and insertion of "water channels", known as aquaporins, into the membranes of the collecting tubules of the kidney. This increased number of aquaporins increases the permeability of the collecting ducts, which results in a greater water reabsorption in the kidneys.
