Water clarity, or turbidity, measures the amount of sediment and debris in a body of water. Since light cannot shine into water with low clarity, turbidity is a factor that is considered when monitoring water quality. Which of the following organisms would be most negatively affected by unclear water?
A. plants growing on the lake floor
B. trout feeding near the lake surface
C. trees growing along the lake shore
D. geese nesting on the bank of the lake
Answers
Answer:
plants growing on the lake floor
Explanation:
Have a nice day!
The organisms that would be most negatively affected by unclear water are plants growing on the lake floor. The correct option is A.
What is water clarity?Water clarity is a measure of how far down the water column light can penetrate. Clear water has low concentrations of suspended soil particles and/or algae.
Water clarity has huge consequences for the diversity and productivity of aquatic life that a system can support because it is closely related to light penetration. Clearer water, for example, allows more sunlight to reach submerged aquatic vegetation.
Water clarity is critical for a variety of reasons. It influences the depth to which aquatic plants can grow, the amount of dissolved oxygen in the water, and the temperature of the water. Fish, loons, and other wildlife rely on clear water to find food.
Thus, the correct option is A.

1) what is the relationship between the fundamental niche and the realized niche of a species?
PLEASE HELP
Answers
The total collection of circumstances that allow an animal (population, species) to live fundamental niche. Realized niche refers to the circumstances that a particular animal really uses.
What connection exists between a species' basic niche and its realised niche?Given its adaptations, the species' possible mode of life is known as the Fundamental Niche. The realised niche can only be the same size as or lower than the basic niche since it results from a species' adaptations as well as from competition with other species.
How do a species' innate niche and its actual niche differ from one another and what keeps them from being the same?When more creatures move in, there is competition for food and mates, or when predators begin to hunt in the area, the fundamental niche becomes smaller.

what would the outcome be if an antibiotic-sensitive homogeneous (no variation) strain of s. aureus was grown in the presence of antibiotics? a. cell growth that begins slowly but proceeds rapidly b. rapid mutation and growth c. no cell growth d. eventual rise of antibiotic-resistant cells e. rapid growth, and then sudden death
Answers
If an antibiotic-sensitive homogeneous strain of S. aureus is grown in the presence of antibiotics, the most likely outcome would be the eventual rise of antibiotic-resistant cells (option d).
Here's a step-by-step explanation:
1. Antibiotic-sensitive strain: This means that the S. aureus strain is susceptible to the effects of antibiotics. In other words, the antibiotics can effectively kill or inhibit the growth of this strain.
2. Homogeneous (no variation) strain: This means that all the individual bacteria within the strain are genetically identical. There is no genetic variation or diversity among them.
3. Growing in the presence of antibiotics: When the homogeneous antibiotic-sensitive strain is exposed to antibiotics, the antibiotics will initially work to kill or inhibit the growth of the bacteria. However, since there is no genetic variation in the strain, all the bacteria will respond to the antibiotics in the same way.
4. Selective pressure: The presence of antibiotics acts as a selective pressure. Some bacteria within the strain may have random mutations or genetic changes that provide them with resistance to the antibiotics.
5. Survival of resistant cells: As the antibiotics continue to exert their effects, the antibiotic-resistant cells within the homogeneous strain will have a survival advantage over the antibiotic-sensitive cells. These resistant cells can continue to grow and divide while the sensitive cells are killed or inhibited.
6. Increase in antibiotic-resistant cells: Over time, the resistant cells will multiply and dominate the population, leading to the eventual rise of antibiotic-resistant cells within the strain.
It's important to note that this process may not occur immediately but can happen over multiple generations of bacterial growth and exposure to antibiotics.
In summary, when an antibiotic-sensitive homogeneous strain of S. aureus is grown in the presence of antibiotics, the most likely outcome is the eventual rise of antibiotic-resistant cells (option D). This is due to the selective pressure imposed by the antibiotics, which favors the survival and growth of bacteria with resistance to the antibiotics.

which immunoglobulin is secreted on to mucosal surfaces as a dimer in response to oral (e.g. sabin polio) or nasal (e.g. flumist) vaccination?
Answers
The most common immunoglobulin isotype found on mucosal surfaces is secretory immunoglobulin A (IgA).
What is immunoglobulin A (IgA)?Both monomeric and dimeric forms of IgA are present in serum and make up around 15% of all globulins. Due to its high concentration in mucosal secretions, secretory IgA, a dimer, serves as the main defense against local infections (e.g., saliva and tears).
Large polymers of IgM, primarily pentamers, circulate in serum and can be delivered to mucosal surfaces by the poly-Ig receptor (pIgR) through epithelial cells (SIgM).
The primary isotype of antibodies seen in nasal and mucosal secretions is known as secretory IgAs (sIgA). They are the primary humoral mediator of mucosal immunity and are released by plasma cells that are close to the mucosal epithelial cells, the site of infection.

does a cell use energy when molecules dffuse in or out of the cell
Answers
Materials move within the cell's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. Diffusion expends no energy.
A passive form of transportation is diffusion. The tendency of a single chemical is to shift from an area of high concentration to an area of low concentration until the concentration is balanced throughout the area. You are knowledgeable about how compounds diffuse via the atmosphere. Consider someone opening a perfume bottle in a crowded room as an illustration. The concentration of the perfume is strongest in the bottle and lowest at the room's perimeter. The perfume vapour will diffuse, or spread, from the bottle, and as it does so, more and more people will start to smell the fragrance.
Instead, diffusion is the dissipation of potential energy when materials migrate down their concentration gradients, from high to low. Different concentrations of materials in various places constitute a kind of potential energy.

sudden overwhelming urge to pee called?
Answers
A sudden overwhelming urge to pee is known as urinary urgency. This is a sudden and intense need to urinate, which can be difficult to postpone or ignore.
It is a common symptom of urinary tract infections, overactive bladder syndrome, and other bladder disorders.
The process of urination involves several steps, including the filling of the bladder with urine, the contraction of the bladder muscles, and the relaxation of the urethral sphincter to allow urine to flow out of the body.
When there is an increase in pressure in the bladder due to a buildup of urine, the bladder signals to the brain that it is time to empty the bladder.
In cases of urinary urgency, the bladder muscles may contract suddenly and without warning, causing a strong urge to urinate.
This can happen even when the bladder is not full, leading to frequent and urgent trips to the bathroom.
To manage urinary urgency, it is important to identify and treat the underlying cause of the symptom.
This may involve lifestyle changes, such as limiting caffeine and alcohol intake, pelvic floor exercises, bladder training, and medication.
In severe cases, surgery may be necessary to correct bladder dysfunction.

Vision problems. Heart attack. Stroke.
Explanation:
Answer:
Many things.
Explanation:
Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.
Too high BP(hypertension):
If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.
Too low BP(hypotension):
If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.
A frog that is dominant for its light green color mates with a brown frog and produces one small brown frog. How is this possible if the green color is dominate?
Answers
Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

List the five major types of species interactions and how those interactions affect the two species involved
Answers
Answer:
here
Explanation:
Competition & Predation.
Commensalism.
Parasitism.
Mutualism.
Amensalism.
Predation: One Wins, One Loses
Predation includes any interaction between two species in which one species benefits by obtaining resources from and to the detriment of the other. While it's most often associated with the classic predator-prey interaction, in which one species kills and consumes another, not all predation interactions result in the death of one organism. In the case of herbivory, a herbivore often consumes only part of the plant. While this action may result in injury to the plant, it may also result in seed dispersal. Many ecologists include parasitic interactions in discussions of predation. In such relationships, the parasite causes harm to the host over time, possibly even death. As an example, parasitic tapeworms attach themselves to the intestinal lining of dogs, humans and other mammals, consuming partially digested food and depriving the host of nutrients, thus lowering the host's fitness.
Competition: The Double Negative
Competition exists when multiple organisms vie for the same, limiting resource. Because the use of a limited resource by one species decreases availability to the other, competition lowers the fitness of both. Competition can be interspecific, between different species, or intraspecific, between individuals of the same species. In the 1930s, Russian ecologist Georgy Gause proposed that two species competing for the same limiting resource cannot coexist in the same place at the same time. As a consequence, one species may be driven to extinction, or evolution reduces the competition.

supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?
Answers
Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.
