Increased soil acidity may result in decreased crop and forest growth as well as the leaching of substances that harm water quality in nitrogen cycle such as heavy metals.
What could have a detrimental impact on the nitrogen cycle?By changing the quantity of nitrogen stored in the biosphere, researchers have found that people are interfering with the nitrogen cycle. Fossil fuel burning is the main offender because it produces nitric oxides into the atmosphere, which react with other substances to create smog and acid rain.
What are the two things that disturb the nitrogen cycle?The use of artificial nitrogen fertilizers, the burning of fossil fuels, and the discharge of nitrogen into wastewater are only a few human actions that have significantly changed the global nitrogen cycle. The natural environment system can suffer if the global nitrogen cycle is altered by humans.

both photosynthesis and cellular respiration are cellular processes that involve glucose. how do these two processes differently affect the metabolism of glucose?
Glucose is produced during photosynthesis to hold the energy that are gathered from light whereas during cellular respiration, glucose is broken down to release stored cellular energy.
How does both the two processes affect the metabolism of glucose?Photosynthesis makes the glucose that is used in cellular respiration to produce ATP and then glucose is turned into carbon dioxide, which is used in photosynthesis. Water is broken down to form oxygen during photosynthesis and oxygen is combined with hydrogen to form water in cellular respiration.
Photosynthesis converts carbon dioxide and water into oxygen whereas cellular respiration converts oxygen and glucose into water and carbon dioxide.

Which of the following is the BEST explanation of the role of DNA and RNA in making proteins?
A. DNA unwinds into two separate strands, and a complementary copy of each is produced during replication. During transcription, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of thymine. During translation, each set of three bases in the mRNA results in an amino acid being added to a chain, and a protein is formed.
B. DNA unwinds into two separate strands, and an exact copy of each is produced during replication. During transcription, a DNA strand is copied to produce mRNA, which is an exact copy of the DNA strand except that uracil takes the place of thymine. During translation, each set of three bases in the mRNA results in a protein with a specialized function being formed.
C. DNA unwinds into two separate strands, and a complementary copy of each is produced during replication. During transcription, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of adenine. During translation, each base in the mRNA results in an amino acid being added to a chain, and a protein is formed.
D. DNA unwinds into two separate strands, and an exact copy of each is produced during replication. During translation, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of thymine. During transcription, each set of three codons in the mRNA results in an amino acid being added to a chain, and a protein is formed.

What is photosynthesis?Photosynthesis is defined as a process in which solar energy is captured and organic molecules are produced. This process is fundamental for the survival of life on the planet and is the main way in which energy enters the biosphere.
Where does photosynthesis take place?Photosynthesis takes place in chloroplasts. Chlorophyll and carotenoids are arranged in the thylakoids of chloroplasts in units called photosystems. Two steps can be observed in photosynthesis: light reactions and carbon fixation reactions. At the end of photosynthesis, carbohydrates are produced.
How is ATP produced in the cell?The breakdown of glucose occurs to generate ATP. In organisms without mitochondria, such as bacteria, respiration takes place in a structure called a mesosome. This process uses glucose and oxygen and produces ATP, carbon dioxide and water.

Why are skeletal muscles striated?
Question options:
A) T-tubules cause the striations
B) Sarcoplasmic Reticulum causes the striations
C) The components of a sarcomere together cause the striations
D) Mitochondria cause the striations
The striations in skeletal muscles are caused by the components of a sarcomere working together.
What is skeletal muscle?Skeletal muscle is one of three major muscle tissues in the human body. Each skeletal muscle is composed of thousands of muscle fibers that are linked by connective tissue sheaths. Individual bundles of muscle fibers in skeletal muscle are known as fasciculi.Sarcomeres are the basic contractile units of muscle fibers made up of actin and myosin filaments. These filaments interact and slide past one another during muscle contraction and relaxation.Skeletal muscles can be found near some of your body's openings as well as between your bones. The muscle attaches to one end of the bone, then stretches across a joint and attaches to another. Tendons (fibrous connective tissues) help.To learn more about skeletal muscle refer to :

which factor(s) are hypothesized as the causes of the triassic-jurassic mass extinction? check all that apply.
Researchers debate theories about the Triassic-Jurassic extinction event's origins, which include climate change, asteroid impacts, and volcanic eruptions.
The Triassic and Jurassic mass extinctions: what happened?The end-Triassic extinction was brought about by massive and extensive volcanic eruptions. Around 200 million years ago, an increase in atmospheric CO2 led to the oceans becoming more acidic and the Earth being warmer, which contributed to the extinction of 76% of marine and terrestrial species.
Which are the top 4 reasons for mass extinctions?Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like a supervolcano erupting or an asteroid impacting Earth have all been responsible for previous mass extinctions. We are aware of them because the fossil record demonstrates how life has altered over time.

Answer:
Unlike other animals, they lack true tissues and organs. Some of them are radially symmetrical, but most are asymmetrical. The shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where the water deposits nutrients and then leaves through a hole called the osculum.
