g The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. it rises to the surface and absorbs wavelengths needed by aquatic plants it causes the water to become murky it decomposes endothermically causing the temperature of the water to decrease below the limits within which most aquatic organisms can live it causes oxygen depletion in the water it causes death of bottom dwelling organisms because it agglutinates and settles to the bottom, poisoning bottom dwelling organisms
Answer:
It causes oxygen depletion in the water
Explanation:
When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.
Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.
Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.
Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.
When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.

6. Samples of atmospheric air and exhaled air were analysed by four groups
of students for oxygen and carbon (IV) oxide content. The following are
the results, expressed in volumes per thousand:
(i) Amount of oxygen in atmosphere = 200
(ii) Amount of oxygen in exhaled air = 160
(iii) Amount of carbon (IV) oxide in atmosphere = 300
(iv) Amount of carbon (IV) oxide in exhaled air =41
Explain the difference in volume of each gas between the atmosphere and
the exhaled air.
Answer:
Due to difference in volume of both atmosphere.
Explanation:
There is difference in volume of carbondioxide and oxygen gas between the atmosphere and the exhaled air because of the volume difference of atmosphere and exhaled air. The volume of atmosphere is larger than the body from where the gases are exhaled. The body has lower space for these gases so these gases are less in concentration in the exhaled air which the body releases as compared to the atmosphere where the concentration of these gases are larger.

Explanation:
Distinguish between an acid and alkaline slant?
Answer:
Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation
Alkaline slant: red, limited glucose in the medium and limited acid formation.
The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.
What are acids?An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.
Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.
The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.
An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.
The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.
The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.
Thus, these are the basic difference between acid and alkaline slant.

Generate a random protein sequence that is 5 amino acids long.
Answer:
Random protein sequence 5 amino acids long
LYSINE - GLUTAMINE - VALINE - GLYCINE - LEUCINE
Explanation:
Proteins are macronutriens formed by amino acids. Amino acids are the monomers of proteins, meaning they are the structural units. These organic compounds are made of amino and carboxyl groups.
For every amino acid there is a DNA sequence:
Lysine: AAA
Glutamine: CAA
Valine: GTG
Glycine: CCC
Leucine: AAT
This protein sequence of 5 amino acids long would be like this in its DNA:
AAA CAA GTG CCC AAT

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population’s ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Delayed density dependence Delayed density independence Extinction vortex Carrying capacityAnswer:
Delayed density dependenceExplanation:
The Delayed density dependence occurs when two species are in interaction (prey-predator or parasite-host), and the dynamic of each population follows the dynamic of the other population. The natality and mortality rates of one species follow the rates of the other species.
Delayed density dependence dynamics regulate populations and allow the occurrence of equilibrium or balance in nature.
Predator-prey scenarios
Assuming that the prey lives in the ideal environment with no predators, it shows an exponential growth rate. Prey can grow, develop, and reproduce, increasing its population size. The more available items, the more predator there will be. The predator population increase in size, and its presence affects the prey populations, leading it to decrease. So there are fewer available items to prey on.
The prey population also affects the predator population. After the increase in the predator population size, the number of available prey decreases. The predator lives in an ideal environment but depends on the prey density. The more predators there are, the fewer prey there will be left. The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.
So, to sum up,
prey population increases in sizepredator population increases in sizeprey population decreases in sizepredator population decreases in sizeIn this particular example, the wolves population follows the moose population and vice-versa. It is not simultaneous. It happens with a delay.
Moose influences the wolf population because they are their source of food. The more moose, the more wolves there are. The fewer moose, the fewer wolves there are.
This is a density-dependent dynamic because both populations are affected when they reach a high value.
