Actinobacteria sp. are fermenting organisms, which do not require oxygen to survive. These organisms break down organic material and convert it to inorganic material. Which part of the carbon cycle does this describe?
Answers
Answer:
Decomposition
Explanation:
The "Carbon Cycle" consists of four processes and these are: Photosynthesis, Decomposition, Respiration and Combustion.
After the process of photosynthesis, the animals will consume the plants and then will die and so will the plants after many years later. They will decompose and turn into fossil fuels, which are organic materials. The organic materials will then be decomposed by Actinobacteria into inorganic materials. These stays into the soil and allows the growth of plants once more. Then, the Respiration process follows.

Answers
Answer:
Reactants of the cellular respiration process are:
1. C6H12O6
The phase reactant is used: Glycolysis
Location: cell cytoplasm
In cellular respiration, the glucose is used up in the phase known as glycolysis which is performed in the cell cytoplasm that breaks the glucose into 2 molecules of pyruvate.
2. 6O2
The phase reactant is used: oxidative phosphorylation
Location: mitochondrial matrix
Oxidative phosphorylation is the phase of cellular respiration that forms the ATP by the transfer of the electron to the oxygen which reduced the oxygen to water.
Products of cellular respiration are -
1. 6CO2
The phase reactant is used: Krebs cycle
Location: mitochondrial matrix
2. 6H2O
The phase reactant is used: oxidative phosphorylation
Location: mitochondrial matrix inner membrane
3. 38ATP
The phase reactant is used: oxidative phosphorylation, Glycolysis, Krebs cycle
Location: mitochondrial matrix, cell cytoplasm and inner membrane mitochondrial matrix
Aerobic respiration takes place in three steps: Glycolysis occurs in the cytoplasm. Krebs cycle occurs in the mitochondrial matrix. And oxydative phosphorilation that occurs in the internal mitochondrial membrane.
------------------------------
Through cellular respiration cells degrade organic compounds and produce energy.
Aerobic respiration takes place in three steps or stages: Glycolysis, Krebs cycle and oxydative phosphorilation.
Glycolysis ⇒ Occurs in the cytosol
Process through which the cell partially decomposes glucose and turns it into pyruvate. These enzymatic reactions do need no oxygen to occur. So this step is shared by aerobic and anaerobic respiration.Glycolysis transforms one glucose molecule (6-C) into two pyruvate molecules (3-C).The net product of glycolusis are two pyruvate molecules (3-C), two ATP, and two NADH.
The Krebs cycle ⇒ takes place in the mitochondria matrix.
Pyruvate, the main product of glycolisis, enters the mitochondria matrix and turns into Acetyl CoA. Once in the matrix, it enters the Krebs cycle.Each cycle consumes one Acetyl CoA molecule, releases two carbon dioxide molecules, and produces three NADH, one FADH₂, and one ATP molecule. Since two molecules of pyruvate are produced during glycolysis, the krebs cycle occurs twice per glucose molecule.
Oxidative phosphorilation
Electron transporter chain is placed in the internal mitochondrial membrane The process uses electrons from NADH and FADH₂ to produce ATP. Different redox reactions occur to pass electrons along the chain. At the end of the chain, electrons are sent to O₂ molecules, which also receive protons to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule. The proton gradient is used to produce ATP molecules.According to this theoretical framework, we can complete the table.

If you have a storm that has winds of 100 MPH and it is moving at 50 MPH what is the total wind speed with the additive effects?
Answers
Answer:
I would assume 150 MPH, I could be wrong however.
Explanation:
Based on the definition of additive affects, "An effect in which two substances or actions used in combination produce a total effect the same as the sum of the individual effects," I would assume that since the wind speed is 100 MPH and the storm is moving at 50 MPH the total wind speed would be 150 MPH. This would make sense because if you think about it, if a storm with 100 mph winds is coming at you at 50 mph, the force of the 50mph winds would hit you when it gets to you along with the 100 mph winds, but again, I am not totally sure.

What is direct observation?Direct observation refers to the process of observing and recording the behavior or actions of an individual or group without any manipulation or interference. This method is typically used in research studies, such as in psychology, sociology, and anthropology, to study natural behavior and gather data in a non-invasive way.
Direct observation can take place in a variety of settings, including in natural environments, in laboratory settings, or in the field. The observer may use a variety of techniques, such as taking notes, recording audio or video, or using structured observation forms to document the behavior or actions being observed. It is considered a reliable method of data collection as it provides an accurate representation of the actual behavior or actions, rather than relying on self-reported information.

Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.
Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.

How does the salinity in water change as you move from inland areas out towards to ocean? Be sure to include the phrase "brackish waters" in your response.
Answers
Answer:
The salinity of water increases as you move from inland areas out towards to ocean.
Explanation:
Salinity refers to the concentration of salt in the water. The salinity of water increases as you move from inland areas out towards to ocean because the ocean has high salinity than the inland areas. That is it can be said that the ocean contains brackish water. Brackish water has more concentration of salt than freshwater.
Salinity is defined as the concentration or amount of salt present in the water body. The salinity increases from inland areas out towards the ocean.
The salinity increases as we move from inland areas to the ocean. Evaporation and the formation of ice are the primary causes of salinity in oceans.
In oceans, the middle regions are generally referred to as brackish waters, which have a higher concentration of salt than freshwater but it is lower than the salinity of the sweaters.
Thus, the salinity increases from inland areas to brackish water, and then deep into the oceans.

what changes will occur in the patients cells ?
what can be done to fix this problem ?
Answers
Answer:
The patient's cells will swell and then burst. The solute concentration outside the cell is lower than inside the cell, so water will move into the cells.
Mike would have to give the patient a hypertonic solution, which will cause water to move out of the cell and the cell to shrink followed by an isotonic solution, which should regulate the concentration inside and outside the cell.

Answers
Answer:
Minerals from the land are washed into the ocean.
Salt in the ocean comes from the runoffs from the land, So the correct option is C. The minerals from the land are washed into the ocean.
Why are oceans salty?A large percentage of the earth is covered by water but 97 % of this water is salty and cannot be used. The salt in the ocean is added to by the erosion of rocks.
Rainwater contains dissolved carbon dioxide (CO2) from the surrounding air, which makes the rainwater slightly acidic due to the presence of carbonic acid. Rainwater physically damages the rock, and the acids chemically degrade the rock and transport salt and minerals in the form of ions. These ions are carried to streams and rivers, and eventually to the ocean.
The density of the ocean water is affected by the level of salinity. Higher levels of salinity cause water to be more dense and heavier and sink under less salty, warm water. This also affects ocean currents. In addition, marine life may need to adjust their saltwater intake.
