Animals like clams and oysters need calcium carbonate-containing materials to construct their shells. Human activity is quickly changing the chemistry of the ocean and impacting marine life by releasing carbon dioxide into the atmosphere.
Oysters remove what from the water, exactly?Oysters obtain their nutrition by filtering water to remove algae, which in turn removes nutrients that, if present in excess, might harm aquatic life. An adult oyster alone is capable of filtering more than 50 gallons of water each day.
Oysters and clams both purify water, right?As they grow, oysters, clams, and other shellfish absorb excess nitrogen from the water and use it to build their shells and other tissues, which helps them function as effective filter feeders.

The diatom is 0.05 mm long along its diameter.
What is meant by diatom?Diatoms are single-celled microscopic organisms that are found in many different aquatic environments.
They are part of a larger group of algae known as the phytoplankton and are responsible for approximately 20 percent of the photosynthesis on earth.
Diatoms are unicellular, meaning they are comprised of a single cell, and are encased in a silica shell that is composed of two interlocking halves.
This shell is called a frustule and is unique to diatoms. Diatoms are incredibly diverse, with over 20,000 species known to exist.
Diatoms are incredibly important to the environment, as they are responsible for the production of oxygen, the sequestration of carbon dioxide, and the cycling of nutrients.
They also provide food for organisms in the ocean, such as small fish, crustaceans, and other plankton.
Diatoms are also used in research, for example to examine the effects of pollutants in the environment.
Diatoms are also used in a variety of commercial applications, such as filtration and as abrasives in cleaning products.

Predict one way the removal of a reef might impact erosion or deposition along a shore.
One of the many processes that affect a river system's health is erosion.
Rock, soil, and sediment are moved downstream during the erosion process by the force of a river. Increased erosion depletes our land's vital topsoil and pollutes our rivers, oceans, and lakes, lowering the quality of the water.
Coral reefs are to the shorelines and trees are to the ground. Without coral reefs beneath them, beaches and shorelines are easily eroded by ocean currents.
To protect the shoreline, the water is accelerated and slowed down as waves strike the reefs. Without reefs, the currents may change their course permanently, causing climate change since warm and cold water mix differently in different parts of the world.
Poor water quality has an adverse effect on the overall ecosystem when it flows from the land to the Great Barrier Reef. Excessive sedimentation on reefs accelerates the growth of algae, which suffocates coral and impairs its ability to reproduce and expand.

Explain how ecosystems could be impacted from each indicator of climate change:
D.) shifting temperatures and weather patterns have forced some species to move to new locations or to new ecosystems entirely. The migration patterns of some species have also been altered because species must move to comfortable climatic conditions for their survival
Answer:
There are two main impacts on marine ecosystems from climate change: (a) rise of sea surface temperature; and (b) ocean acidification (due to CO2). Both (a) and (b) will impact on marine life. For example, increased in sea surface temperature caused a shift in distribution of fishes toward poles. Warming will likely affect the successful recruitment of marine organisms. In addition, warming may cause more toxic algal blooms (dinoflagellates and diatoms). Dinoflagellates and diatoms produce toxins which can then be accumulated in seafood organisms via the food chain pathways. Calcifying organisms (e.g. pteropods, corals, and molluscs) would be more vulnerable to changes in ocean acidification.

What are the main reasons of mutation stop codon?.
The substitution of a single base pair in a triplet codon causes nonsense mutations, which result in one of three stop codons (UAG, UAA, and UGA)
As a result, the triplet codon for an amino acid is changed to one that causes mRNA translation to end too soon and causes a truncated protein.
Because stop codons do not encode for an amino acid but rather mark the completion of protein synthesis, they are also known as nonsense codons. So, prematurely introducing a nonsense or stop codon into the DNA sequence results in nonsense mutations. In general, a stop codon—UAA, UAG, or UGA—in the ribosome's A site is a signal to stop protein synthesis. As it assures the production of complete proteins, this procedure is the final crucial step in the translation process.

crossing over occurs at the ends of chromosomes, rather than near the centromeres.
Crossing over occurs at the ends of the chromosomes, not close to the centromeres, where DNA segments can easily break and reattach.
Option 2 is correct
Where exactly does chromosome crossing occur?During the pachytene phase of meiosis, when pairs of chromosomes are fully coupled, crossing occurs. At diplotene, after homologs divide, the locations of trying to cross become visible as cytokinesis, which holds the two homologs of a pair together until segregation during anaphase I.
Which of the following is true regarding crossing over?Genes are exchanged at random between the parents' chromosomes. During the crossing-over process, gametes generate novel gene combinations.
Question incomplete:What are the requirements and consequences of crossing over?
1. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA.
2. Crossing over occurs at the ends of chromosomes, rather than near the centromeres, because segments of DNA near the centromeres cannot break and rejoin easily.

What kind of gene mutation is more likely to result in a nonfunctional protein and why?.
Frameshift gene mutation. A protein's inability to function is more likely to result from a frameshift mutation than from a point mutation. This modifies the nucleotide bases in codons, changing their base sequence.
Frameshift gene mutation changes the amino acid sequence and the proteins that come after it. Changing the way a DNA sequence is read, for as through an insertion or deletion, can result in a frameshift mutation, a specific kind of genetic modification. A change in the reading frame occurs when one or more nucleotides are added or deleted. Cystic fibrosis is caused by two frameshift mutations in the CFTR genes, one of which results in the insertion of two nucleotides and the other in the deletion of one.

Explanation:
diagnostic test that measures electrical activity within muscle fibers
The electrical activity that occurs when a muscle is stimulated by a nerve is measured by electromyography (EMG). The examination is done to identify any neuromuscular anomalies.
Electromyography (EMG) detects the electrical activity that occurs when a neuron stimulates a muscle. The test is used to identify aberrant neuromuscular function. One or more tiny needles, commonly known as electrodes, are introduced through the skin and into the muscle during the test. An oscilloscope is then used to display the electrical activity that the electrodes picked up (a monitor that displays electrical activity in the form of waves).
In order to hear the activity, an audio amplifier is employed. The electrical activity of muscles during rest, a light contraction, and a strong contraction is measured by EMG. At rest, muscle tissue doesn't typically create any electrical signals. There is a brief period of activity when an electrode is introduced, but there is no signal beyond that.
