Answer:
There is an important relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.
Explanation:
There is a great relationship among homeostasis, defective mitochondria and the symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.
The relationship among homeostasis, defective mitochondria and the symptoms caused by LHON is the following:
The power center of the cell, the mitochondria are also involved in homeostasis, the maintenance of a stable internal environment even in the face of variations in the external environment.
Mitochondrial diseases can be caused by inherited mutations in mitochondrial DNA or defects in the proteins responsible for regulating mitochondrial division, affecting the body's homeostasis.
Leber's Hereditary Optic Neuropathy (LHON) is the first disease associated with a mutation in the mitochondrial genome, specifically it produces the specific degradation of neurons involved in sending information from the eye to the brain (RGC).This disease is caused almost entirely by three mutations in mitochondrial DNA (mtDNA).The first symptoms are blurred vision, with unilateral or bilateral onset, which over time affects and / or worsens in both eyes, with loss of visual acuity and color vision.Vision loss is painless and is caused by degeneration of the optic nerve, specifically of the retinal ganglion cells (RGC).
Therefore, we can conclude that LHON is a disease associated with a mutation in the mitochondrial genome affecting the body's homeostasis.

First drag pink labels to pink targets to identify the digestive organs. then drag blue labels to blue targets to identify the source of each digestive enzyme or fluid.
Answer:
According to the diagram, the digestive organs on the pink targets includes:
a.) Liver, c) esophagus, d) gall bladder, e)Stomach, I) Small intestine j) Pancreas
The source of each digestive enzyme or fluid on the blue targets includes: b) bile, f) pepsin, g) Intestinal enzymes, h) Pancreatic juice.
Explanation:
The digestive system is the collective name used to describe the alimentary canal, accessory organs and a variety of digestive processes that takes place at different level in the canal to prepare food eaten for absorption.
Accessory organs of digestion generate various secretions which are poured into the tract to aid in the digestion of the food taken. They include: salivary gland, pancreas (secrets pancreatic juice), liver ( secrets bile), gall bladder ( stores bile).

Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). What is the effect of catalase on the decomposition of hydrogen peroxide?
Answer: Catalytic effect
Explanation:
Catalyst is a substance which speed up the rate of the reaction occurring inside the body.
The catalase is an enzyme which is responsible for catalyzing the decomposition reaction or break down of the hydrogen peroxide. And all living things exhibit or possess this enzyme. The enzyme catalyzes the decomposition of the hydrogen peroxide into water and oxygen.

What is an example of the lithosphere?
Answer:
Rocky Mountain range in western North America.
Explanation:
Lithosphere is defined as the rock and crust surface that covers the Earth.
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
Although the rocks of the lithosphere are still considered elastic, they are not viscous. The asthenosphere is viscous, and the lithosphere-asthenosphere boundary (LAB) is the point where geologists and rheologists—scientists who study the flow of matter—mark the difference in ductility between the two layers of the upper mantle. Ductility measures a solid material’s ability to deform or stretch under stress. The lithosphere is far less ductile than the asthenosphere.
There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere.
How the Lithosphere Interacts with Other Spheres
The cool, brittle lithosphere is just one of five great “spheres” that shape the environment of Earth. The other spheres are the biosphere (Earth’s living things); the cryosphere (Earth’s frozen regions, including both ice and frozen soil); the hydrosphere (Earth’s liquid water); and the atmosphere (the air surrounding our planet). These spheres interact to influence such diverse elements as ocean salinity, biodiversity, and landscape.
For instance, the pedosphere is part of the lithosphere made of soil and dirt. The pedosphere is created by the interaction of the lithosphere, atmosphere, cryosphere, hydrosphere, and biosphere. Enormous, hard rocks of the lithosphere may be ground down to powder by the powerful movement of a glacier (cyrosphere). Weathering and erosion caused by wind (atmosphere) or rain (hydrosphere) may also wear down rocks in the lithosphere. The organic components of the biosphere, including plant and animal remains, mix with these eroded rocks to create fertile soil—the pedosphere.
The lithosphere also interacts with the atmosphere, hydrosphere, and cryosphere to influence temperature differences on Earth. Tall mountains, for example, often have dramatically lower temperatures than valleys or hills. The mountain range of the lithosphere is interacting with the lower air pressure of the atmosphere and the snowy precipitation of the hydrosphere to create a cool or even icy climate zone. A region’s climate zone, in turn, influences adaptations necessary for organisms of the region’s biosphere.

Explanation:
Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.
Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.Answer:
B) The individual calcium atom has a positive, not negative, 2 charge.

what significant role does dna play in formation and development of an organism
Answer:
DNA contains the instructions needed for an organism to develop, survive, and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation:
DNA contains the instructions needed for an organism to develop, survive, and reproduce.
What is DNA?
Cells' capacity to store, retrieve, and translate the genetic instructions necessary to create and maintain a live organism is essential to life.
This genetic material is transmitted from one generation of an organism to the next through the reproductive cells of the organism and from one cell to its daughter cells during cell division.
Every living cell contains these instructions as part of its genes, which are the information-containing components that define the traits of a species as a whole and of the individuals within it.
Therefore, DNA contains the instructions needed for an organism to develop, survive, and reproduce.
