The cell bodies of motor neurons to skeletal muscles are located in the A. Posterior/dorsal gray horns B. Limbic system C. Anterior/ventral gray horns D. Gray commissure
The cell bodies of motor neurons to skeletal muscles are located in the anterior/ventral gray horns.
Neurons are cells characterized by a body (called soma), and different kinds of prolongations that will have the task to carry the information to other neurons or tissues - these prolongations are axons (which are usually very long) and dendrites (much shorter than axons).
The motor neurons are the ones that conduct the electric impulse from the motor cortex in the brain to the skeletal muscles in our bodies, making muscle contraction and movement possible.
There are two types of motor neurons:
Upper motor neurons: Their cell bodies are located in the motor cortex in the precentral gyrus of the brain. Their axons synapse onto interneurons in the spinal cord.Lower motor neurons: These neurons have their cell soma located in the anterior gray horns of the spinal cord - from that place, their axons will exit the spine to reach the skeletal muscles that we want to contract to perform specific tasks such as running or grabbing a glass of water.Thus, we can conclude that the somas of lower motor neurons that transmit its impulse to skeletal muscle are located in the anterior gray horns of the spinal cord.

A. digests proteins in the small intestine.
B. emulsifies fats in the small intestine.
C. is made by the gallbladder and stored by the liver.
D. activates trypsin in the small intestine.
E. activates the pancreas.
⚘ Emulsified fats in the small Intestine (B)
Explanation:-Bile is not an enzyme which is made in the liver which helps in the emulsification of fats. Here, Emulsification means the break down of larger molecules of fat into small molecule. The bile is temporarily stored in the Gall Bladder.
The bile juice is then released into the duodenum(the first part of small intestine) through hepato pancreatic duct. The duct carries both enzymes of pancreas and bile. They digest the food in the small intestine[tex].[/tex]

Devon is playing with a yo-yo. A yo-yo has an axle in the middle of two plastic halves. A string is tied around this axle. As Devon moves his hand, the yo-yo goes up and down. The yo-yo converts potential energy to kinetic energy as it moves. Which of the following pictures represents the yo-yo with the most potential energy? A. X B. Y C. Z D. W
Answer:
second image or B. Y
Explanation:
Potential energy is defined as the stored energy of an object when work is done against a force.
The second image in which yo-yo is ready to stretch out, represents the yo-yo with the most potential energy because the distance is highest from the ground and so yo-yo at this position will have highest gravitaional potential energy. The potential energy will be converted into kinetic energy when released in air.
Hence, the correct image is "second image" or "B. Y"

Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Paclitaxel works by interfering with normal microtubule breakdown during cell division and Vinblastine works by binding tubulin, thereby inhibiting the assembly of microtubules. How and where specifically do you think these drugs would stop a cancer cell
Answer:
by inhibiting the mitotic spindle plasticity
Explanation:
In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).

Why are male cats unable to express both orange and non-orange colors simultaneously in the same way as female cats?
O male cats only have one X chromosome
O only female cats inherit non-orange genes
O male cats have a dominant Y chromosome
only female cats inherit orange genes
The gene that codes for orange/non-orange color is X-linked. Female cats can express orange and non-orange simultaneously. Males, who only have one X chromosome, can express either orange or non-orange.
-----------------------------------------------
Male cats can only express one or two coat colors, but not three as females do. The combination of three simultaneous colors seems to be exclusive for females.
In cats, hair color is coded by different genes. In the particular case of orange color, we are referring to a codominant, diallelic, X-linked gene. Chromosome Y does not have an associated gene for the orange color.
The orange gene is diallelic, being
O the dominant allele ⇒ codes for orange ⇒ inhibits the expression of blacko the recessive allele ⇒ codes for not-orange ⇒ allows the expression of blackMales, who carry only one X chromosome, can be either
orange ⇒ X⁺Y (Where + symbol represents the dominant allele O)non-orange ⇒ X⁻Y (Where - symbol represents the recessive allele o)But, since females carry two X chromosomes, they can express either
orange ⇒ H0m0zyg0us dominant ⇒ X⁺X⁺ non-orange ⇒ H0m0zyg0us recessive ⇒ X⁻X⁻ combination of black and orange ⇒ Heter0zyg0us ⇒ X⁺X⁻----------------------------------------

● Light sensitivity
● Beginning stages of kidney failure
Answer:
Explanation:
After seeing her symptoms at the student health center, she was immediately referred to a hospital. In the hospital she was diagnosed with a disease of CNS (central nervous system). The primary cause of a CNS infection is a result of the communication of an infectious disease. In these diseases, some are contagious and spread easily among the people and other types are also infectious and spread by pathogen organisms.
Step 2
Based on the symptoms of stiff neck, fever, vomiting, and light sensitivity, she was suffered by the meningococcal meningitis. The reason behind this diagnosis is that these symptoms are majorly impacted this diagnosis. Meningococcal meningitis is a bacterial form of meningitis. It is an infectious disease caused by Neisseria meningitidis bacteria. It is a serious infection of the thin lining that surrounds the brain and the spinal cord.
