A doctor sees a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease.
Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?
Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.Learn more in:

Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth causing earthquakes.
Too many greenhouses gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing volcanic eruptions.
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming.
Answer:
I think it would be the goal warming one :)
If the human population continues to grow and emit gases then this may lead to global warming. The green house gases in the atmosphere block heat and hence cause global warming. Thus, the correct option is D.
What is Global warming?Global warming is the change in climate, referring to the long-term increase in the planet's temperature. It is caused by increased concentrations of greenhouse gases in the atmosphere. This is mainly because of human activities such as burning fossil fuels, pollution, and farming.
The greenhouse gases in the atmosphere absorb the heat. They radiate this heat. Some of the heat will leave the Earth, some of it will be absorbed by greenhouse gases, and some of it will get back at the planet's surface. With the increase in the greenhouse gases, heat will stick around, warming the planet.
Further increase in the green house gases lead to melting of glaciers and increased precipitation. This will change the climatic conditions globally.
Therefore, the correct option is D.

The coordinated action of two types of myofilaments, actin and myosin, results in muscle contraction. The muscles contract as actin filaments slide over myosin filaments. When the muscle is in a relaxed state, the myosin heads are ready to bind with the actin filament. However, they are not able to bind due to
a.
the absence of ATP
b.
a high concentration of Ca++ ions
c.
blockage of the attachment site
d.
alcoholic fermentation
Answer:
I think due to absence of ATP but I'm not sure.. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Myosin heads are ready to bind with the actin filament they are not able to bind due to the absence of ATP.
How two myofilaments involved in muscle contraction?Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.
What happens to the actin and myosin filaments when a muscle contracts?Myosin movement appear to be a kind of molecular hop. The myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward again to bind actin in a new cycle.
What happens to actin and myosin during muscle relaxation?Relaxation occurs when nerve stimulation stops. Calcium gets moved back into the sarcoplasmic reticulum shattering the link between actin and myosin. Actin and myosin then return to their unbound state causing the muscle to relax.

Describe why some water uses are called consumptive
Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.

a. Write the following number in scientific notation: 0.03054 grams
b. Write the following in ordinary notation: 3.02 x 10-5
c. Evaluate the following: (3.3 x 10-4mL) = (1.1 x 10-6 mL)
Answer:
a. 0.03054 b. 0.000032 c. sorry I am not perfect
Explanation:
a. In the number 0.03054 , you need to move the decimal point two places to the right to get to 3.054 (which is between 1 and 10). Since you moved the decimal point two places to the right, you must indicate it by saying that you multiplied 3.054 by 10−2 . Think about it: 3.054×10−2=0.03054 . b. Answer: 0.0000302 Step-by-step explanation: When 10 is to the power of a negative number, "move" the decimal dot left. 10⁻⁵ means to "move" the decimal 5 times to the left. 1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02). 0000003 . 02 2. Count 5 place values over. 00←0←0←0←0←3 . 02 3. Put the decimal behind the digit. 00 . 0000302 4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal. 0.0000302 <= Final answer c. sorry but I am not perfect at thisA. 0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
B. 3.02 x [tex]10^-^5[/tex] = 0.0000302
C. 3.3 x [tex]10^-^4[/tex] mL= 300
Powers of 10 are used in scientific notation to express extremely large or extremely small quantities. The formula is "[tex]\rm a * 10^b[/tex],"
where "a" is an integer representing a value between 1 and 10 (inclusive), and "b" is an integer representing a power of 10.
To write 0.03054 grams in scientific notation, we move the decimal point three places to the right to make the number between 1 and 10. this results in:
0.03054 grams = 3.054 x [tex]10^-^2[/tex] grams
To write [tex]3.02 * 10^-^5[/tex] in conventional notation, as indicated by the exponent, we move the decimal point five places to the left. this results in:
3.02 x [tex]10^-^5[/tex] = 0.0000302
To evaluate (3.3 x [tex]10^-^4[/tex] mL) / (1.1 x [tex]10^-^6[/tex] mL), we divide the numbers in the numerator and denominator:
[tex](3.3 * 10^-^4 \rm mL) / (1.1 * 10^-^6 \rm mL) \\= (3.3 / 1.1) * (10^-^4 / 10^-^6) \\= 3 * 10^2[/tex]
Therefore, (3.3 x [tex]10^-^4[/tex] mL) is equal to 300.

How is loss of biodiversity connected to extinction of organisms?
Answer:
In an ecosystem, everything is connected. All ecosystems have some form of food chain and symbiosis. This means that animals rely on each other for life. If one animal were to die then others would be negatively affected. Overall, this means that when biodiversity is lost it becomes harder for organisms to survive. For example, pandas rely on bamboo to survive. So, when it gets cut down and destroyed the pandas also suffer. Additionally, in ecosystems, a wide variety of organisms helps other living creates have more forms of survival. This shows how important biodiversity is.
What do you think interphase is? What might the cell be doing in this phase? Think about the prefix "inter". Write your best definition - it's ok if you're not sure, just try your best!
Answer:
Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division
Interphase is the part of time which mostly the cell utilises for its functionality.

body system is responsible for exchanging gases with the environment? ( point)
A.endocrine
B.circulatory system
C. respiratory system
D. nervous system
Answer:
The correct answer would be in this case C) respiratory system. It is the main source where the process of gas exchange occurs, taking in oxygen and breathing out carbon dioxide into the rest of our surrounding environment.
The respiratory system is responsible for the exchange of gases with the atmosphere. So the correct option is C.
What is the respiratory system?
The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with inhalation and exhalation, it:
Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.Shields your airways from irritants and dangerous chemicals.
Therefore the correct option is C.

Glucose molecules bond together in a process known as dehydration synthesis. What
happens in this process?
The reaction uses water molecules to break the bonds in each glucose.
O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.

Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

Explanation:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
What is electronic configuration of carbon?Carbon atomic number is 6. Its electronic configuration is 1s2 2s2 2p2. As you can see from the electronic configuration the inner shell has 2 electrons and the outer shell with principal quantum number 2 has 4 electrons.
An atom is made up of electrons, protons and neutrons. Both protons and neutrons are located in the nucleus of the atom, while electrons are in the shell/s. The shell of an atom is the orbit on which the electrons revolve around the nucleus. The number of shells in an atom extends from the first, n =1, to infinity, n = ∞, depending on the number of electrons in the given atom.
The first shell, n =1, is the ground state and can only contain a maximum of 2 electrons. The inner shell contains two electrons and the outer shell contains four electrons.
Therefore, Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
