The lake's pH has become acidic; in 1989, it was 6.7; by 1996, it had dropped to 5.1. This shows that the increase in the acidity which has several bad impacts on the lake water ecosystem and its community.

The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.

When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.

Hence, the acidity of the lake increased and the pH decreased in these years, from 1989 to 1996.

Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction. The phenolase changes the phenols into melanin, which has a brown colour.

Statements "whereas the carbohydrate and fat you eat are used mostly to give you energy, protein is used mostly to build and maintain your body." is True. The statement correctly explains the role of carbohydrates, fats, and proteins in the body of organisms

Carbohydrates and fat are the primary sources of energy for the body. They are broken down into glucose, which is then used to produce energy for various bodily functions. On the other hand, protein is primarily used to build and maintain the body's tissues, including muscles, bones, and organs. While protein can also be used as a source of energy, it is not the primary source and is only used when carbohydrate and fat sources are not sufficient.

The process of translating mRNA into the chain of amino acids that makes up the produced protein occurs on ribosomes in the cytoplasm of the cell.

The process of making proteins from an mRNA template is known as translation. Ribosomes are involved in the process of translating the nucleotide sequence on an RNA molecule into the amino acid sequence of a protein. A mature mRNA transcript is docked by ribosomes and tRNA, which then enlist many enzymes in an ATP and GTP-dependent process.

Ribosomes, intricate cellular components that hold both RNA and protein, are where translation takes place. Ribosomes are attached to mRNA when transcription is still taking place in prokaryotes (organisms without a nucleus). From the 5' end of the mRNA sequence to the 3' end, three bases are read at a time, and one amino acid from the corresponding transfer RNA (tRNA) is added to the developing chain until the entire protein chain is put together.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Answer:The difference between aerobic and anaerobic respiration.

Aerobic respiration  Anaerobic respiration

1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.

2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).  

3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid

4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.

Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.

Explanation:

The correct answer is: C. the mass of the central object.

In the equation for the speed of an object in a circular orbit, the variable "m" represents the mass of the central object. The equation itself is not provided in the question, but in the context of circular motion, the speed of an object in a circular orbit is influenced by the mass of the central object around which it is orbiting.

This equation is derived from the gravitational force between the two objects involved in the orbit. The mass of the central object, such as the Sun in the case of planetary orbits, affects the gravitational pull on the orbiting object. The greater the mass of the central object, the stronger the gravitational force, and consequently, the faster the object needs to travel to maintain a stable orbit.

The mass of the orbiting object, represented by another variable, is also a factor in the equation, but it does not appear to be part of the options provided. Therefore, the most appropriate answer is that "m" represents the mass of the central object.

The m in the equation would represent the mass of the central object.

Centripetal force and gravitational force theories can be used to calculate the speed of an object in a circular orbit. The following formula can be used to determine an object's speed in the case of a circular orbit around a central body, such as a planet or star:

v = √(G * M / r)

v = speed of the object in the circular orbit

G =  gravitational constant

m =  mass of the central body

r = radius or distance between the center of the central body and the object

Explanation:

Mitochondrial diseases are caused by mutations in the mitochondrial DNA, which is located in the mitochondria. These mutations are usually inherited from the mother, as the mitochondrial DNA is passed down from the mother to her children.

Mitochondria are organelles found in the cells of all eukaryotic organisms, which are responsible for generating most of the cell’s supply of chemical energy. They are often referred to as the “powerhouses” of the cell. Mitochondria are essential for life and are involved in a variety of cellular processes, such as metabolism, cell growth, and cell death. They contain their own DNA and can replicate independently from the cell. Mitochondria are also involved in several metabolic pathways, such as the tricarboxylic acid cycle, the beta-oxidation of fatty acids, and the synthesis of amino acids. Mitochondria are essential for life and have been linked to a variety of degenerative diseases, such as Parkinson's disease, Alzheimer's disease, and diabetes.

It is very rare for a mitochondrial disease to be inherited from the father or contracted from a viral, bacterial, or parasitic infection.
