1. How many peptide bonds would exist in this polypeptide?
A polypeptide is made up of multiple amino acids that are linked together by peptide bonds. The number of peptide bonds in a polypeptide is one less than the number of amino acids present. So in a polypeptide made from 75 amino acids, there would be 74 peptide bonds.
2. How many water molecules were formed in this process?
The process of linking amino acids together to form a polypeptide is called a condensation reaction. In this process, one water molecule is produced for every peptide bond formed. In this case, since there are 74 peptide bonds in the polypeptide, 74 water molecules were formed.
3. What type of reaction is involved in making a polypeptide?
The process of linking amino acids together to form a polypeptide is a condensation reaction. This type of reaction involves the formation of a peptide bond between two amino acids, which is accompanied by the loss of a water molecule.

phospholipid bilayer
The fundamental structural element of the membrane is the phospholipid bilayer, which forms an impermanent barrier between two aqueous compartments.
Our cells' lipid bilayer is made up of hydrophilic head groups and hydrophobic tail groups. The chemical structure displays the hydrophilic head and hydrophobic tails. Lipid molecules can be classified into various groups. They are unable to identify the owner of hydrofluoric acid that contains a phosphate group, two tails made of fat, and an alcohol molecule. In this instance, we can observe that the oil and the liquid are both present in the water. This indicates that they have both hydro and hydrophobic regions. As a result, the bilinear shape behaves as a bilayer and is focused on the water-loving head rather than the tail.

the work of john tyndall and ferdinand cohn ______.
The work of John Tyndall and Ferdinand Cohn explained why some spontaneous generation investigators got different results from those of Pasteur.
Who was John Tyndall and Ferdinand Cohn?In order to create a method of discontinuous heating that effectively destroyed bacteria and their spores, Tyndall used Cohn's discoveries as inspiration.
In microbiology labs today, this procedure is still utilised and is known as "Tyndallization."
John Tyndall and several other British scientists discovered that Pénicillium sp. suppressed bacterial development in the 1870s.
Tyndall came to the conclusion that by excluding oxygen, fungi that were growing in various meat and vegetable infusions killed bacteria.
Thus, the research of John Tyndall and Ferdinand Cohn clarified why certain researchers studying spontaneous generation obtained conclusions that were different from those of Pasteur.

The undigested food stuff enters the colon, where the majority of the water is reabsorbed, after passing through the small intestine.
The stomach and small intestine are where the majority of food is digested, but the large intestine receives the leftover food that hasn't been fully broken down. The water in the large intestine is absorbed, and the food that is still undigested is kept in its lower portion, or rectum. It subsequently transforms its undigested food into the semi-solid substance that is kept in the rectum.

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.

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.

Infiltration: Some of the precipitation seeps into the ground, becoming groundwater.Underground flow: The groundwater flows through the soil and rock underground, following the path of least resistance.
Entering the ocean: As the groundwater reaches the coastal area, it emerges from the ground and enters the ocean, either through a spring or by seeping into the ocean.

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.

What is a problem that a cell needs to overcome if its volume is very large relative to its surface area?.
A cell will divide or die if there is inadequate surface area to maintain its rising volume.
Cells must continually interact with their surroundings in order to live. Gases and food molecules that the cell requires are dissolved in water and must be absorbed, as are waste products of cellular metabolism. All materials enter and exit the cell via the plasma membrane. The interior volume of a cell rises as the cell membrane expands. Because volume rises faster than membrane surface area, the relative quantity of surface area accessible to transmit materials to the a unit volume of a cell continuously declines.
As a result, if the cell develops beyond a certain point, not enough material would be capable of crossing the membrane quickly enough to meet the increased metabolism that occurs as the cellular volume rises. As a result, the cell must either split into smaller cells with favorable surface area/volume ratios or stop functioning.
