Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse
In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae
Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.Learn more about this topic here:

which neuron takes the information from the eye to the brain
Answer:
Optic nerve
Explanation:
Optic nerve: The optic nerve connects the eye to the brain. The optic nerve carries the impulses formed by the retina, the nerve layer that lines the back of the eye and senses light and creates impulses. These impulses are dispatched through the optic nerve to the brain, which interprets them as images.
The neuron that takes information from the eye to the brain is the Optic nerve
There are five (5) types of sensory information ( vision, touch, smell and taste, hearing ) passed to the brain by the different sensory organs and these information are passed via different neurons connected to the various sense organs.
The optic nerve also known as cranial nerve transmits the sensory information ( in form of electrical impulses ) associated with vision to the brain through its nerve fibers ( over 1 million of nerve fibers ) which is interpreted by the brain and passed to the body
Hence we can conclude that the neuron that takes information form the eye to the brain is the optic nerve .

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state
The sympathetic nervous system is responsible for the mouse's physiological state.
The nervous system divides into the central nervous system and peripheral nervous system.
In the central nervous system, we have the brain and the spinal cord.
The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:
The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.
-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.
In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

High blood pressure occurs when there is too much blood flowing through the blood vessels at one time. By changing the amount of water in the blood, blood pressure can change. The excretory system can help to lower blood pressure.
Which would most likely occur in the kidney?
More water would be transferred from the nephron.
Less water would be absorbed into the nephron.
The amount of water in the bladder would decrease.
The amount of water in the blood would increase.
Answer:
c
Explanation:
The kidney plays an essential role in regulating blood pressure by adjusting the volume and concentration of water and solutes in the blood. Therefore, to lower blood pressure, Less water would be absorbed into the nephron. Hence option B is correct.
What is a nephron?The nephron is the functional unit of the kidney that is responsible for filtering waste and excess water from the blood. When there is an excess of water in the blood, the kidney can decrease the amount of water that is reabsorbed into the body.
This would result in more water being excreted from the body in the urine, reducing the volume of blood and lowering blood pressure.
To achieve this, the kidney reduces the secretion of antidiuretic hormone (ADH) or vasopressin, which controls water reabsorption in the kidneys.
This decrease in ADH secretion causes the nephrons to reduce the amount of water they reabsorb from the urine, leading to an increase in urine output and a decrease in blood volume.
Therefore option B Less water would be absorbed into the nephron is correct.
