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.

Which of these correctly relates the photoreceptor to the region of the brain to which it connects?
Photoreceptor connects to visual region.
Photoreceptor connects to gustatory region.
Chemoreceptor connects to visual region.
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.

WHY DOES WATER HAVE A HIGH SPECIFIC HEAT? WHAT IS THE SPECIFIC HEAT OF WATER?
Answer:
Depends on the temperature of it's surroundings.
Explanation:
Answer:
There are two reasons. One of them is that the water molecule is “bent”. It is rotationally asymmetric, meaning that it can “store” more energy in the rotational degrees of freedom than other, symmetric molecules (like diatomic molecules, or CO 2 for example).
The other and more important reason are the hydrogen bonds. When a hydrogen atoms binds with a more electronegative atom (such as oxygen in the case of water), its electron has a higher probability to be found in the vicinity of the oxygen atom, leaving the hydrogen nucleus partly “exposed”. This partial charge on the hydrogen will create a very weak bond with the partly negatively charged oxygen atom of a neighbouring water molecule (remember, the hydrogens’ electrons prefer to be around the oxygen atom instead, making it a bit negatively charged). This electrostatic interaction, or bond, between neighbouring water molecules is the famous hydrogen bond.
Even though each hydrogen bond by itself is weak compared to the bonds in the molecules themselves, there are many neighbours around each water molecule, which means that water can store a significant amount of energy in these bonds. As you add heat to water, instead of speeding up the molecules (increasing their kinetic energy and thus temperature) the hydrogen bonds get broken up, soaking in the additional heat without much change in temperature.

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.
is immunity a function of proteins
Answer:
Yes
Explanation:
Of the many functions of protein in your body, one of its most critical is supporting your immune system. The immune response protects you against harmful microorganisms, including viruses and bacteria, as well as foreign substances that might attack your defenses, such as a thorn or flames from a fire.

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.

What are some (list at least 3) of the phenotypic traits for an individual who has the Marfan genotype?
Answer:
