Chemoreceptor connects to somatosensory region.
Which of these correctly relates the photoreceptor to the region of the brain to which it connects? Photoreceptor connects to visual region
What is photoreceptor ?Photoreceptors can be defined as cells for detecting light. They are composed of the outer nuclear layer that contains the cell nuclei the inner segment that houses the cell machinery and the outer segment that contains photo-sensitive pigment.
Therefore photoreceptors are the only cells that can convert incoming light into an electrical signal that can be carried to the brain via the optic nerve to create conscious vision.

Which type of energy do muscle cells use to produce mechanical energy in the movement of an arm?
Answer:
usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.
Explanation:
The type of energy muscle cells use to produce mechanical energy in the movement of an arm is known as chemical energy.
Which type of energy do muscle cells use?The type of energy that muscle cells use is known as chemical energy. Adenosine triphosphate (ATP) is the energy source for all muscle contractions. Energy is released when ATP is broken into ADP+Pi (adenosine diphosphate and phosphate group).
Maintaining the availability of ATP for muscle contraction is the limiting factor since ATP is not stored in large amounts in skeletal muscle. Muscle contraction converts chemical energy to mechanical energy when ATP is hydrolyzed during cross-bridge cycling.
This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.
Therefore, chemical energy is the type of energy muscle cells use to produce mechanical energy in the movement of an arm.

An offshore oil platform houses a drill for drilling oil. The drill descends from the platform and enters the ocean. At the bottom of the ocean, the
drill starts to dig into the rock. It continues drilling into the rock for another 7,000 feet and then stops. Where does the drill stop?
in the biosphere
in the geosphere
in the atmosphere
in the hydrosphere
Answer:
in the geosphere
Explanation:
The drill will eventually stop within the geosphere.
The biosphere is the region of the earth populated by living organisms. The geosphere is the region of the earth made up of solid rock The atmosphere is the gaseous part of the earth. The hydrosphere is the liquid part of the earth or where water dominates the earth.The drill pierces through the geosphere as it initially passes through the hydrosphere. Eventually, the drill stops within the geosphere.

Pleiotropy is a tough word, not going to lie. It really just means that one gene can control several different traits. Marfan syndrome is an example of a genetic disorder where the presence of one gene causes many different traits to appear. Some evidence suggests that President Abraham Lincoln could have had Marfan's, but the absolute best example (in my opinion) is Peter Mayhew (the original actor that played Chewbacca!) who was over 7 feet tall! What are some (list at least 3) of the phenotypic traits for an individual who has the Marfan genotype?
Answer:
a single genetic disorder that can produce several symptoms ... Marfan syndrome. Genetic heterogeneity is. when the same phenotype may result from the actions of different genes ... An example of a condition that exhibits genetic heterogeneity is ... Polygenic means. the traits are determined by more than one gene.

_____________________________________[tex]\huge\textbf{Cellular Respiration:}[/tex]
Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as Waste Products.

_____________________________________ Best Regards, 'Borz'Which element within the respiratory system is responsible for removing foreign matter from the lungs
Answer:
Cilia
Explanation:
The element which is responsible for this is the Cilia. The form found in a human's respiratory system are known as Motile Cilia and basically act as brooms on the respiratory epithelium lining the respiratory tract. Huge waves of Motile Cilia communicate with one another in order to be able to effectively clean up all dirt and mucus from the lungs in a very organized and unified manner. This helps maintain our respiratory system running as effectively as possible.
