Answer:
Excess sediment in water may cause a reduce in light penetration decreasing algae's(an important food source) ability to photosynthesize therefore not allowing it to grow. It will stop fish from seeing well enough to move around or feed. Sediment can clog fish gills, reducing resistance to disease and lowering growth rates.Certain chemical pollutants bind to sediment and so if there is excess sediment it can very rapidly change the water quality. These
chemicals that bind to the sediment are dangerous to small animals and plants as well as larger forms of life.

Which of the following is the dependent variable in the experiment?
It is something on which other elements depend. A test score, for instance, may be a dependent variable because it could vary based on a number of variables, including how much you studied. How much sleep you got the night before the test, and even how hungry you were.
What dependent variable in the experiment?The thing being measured in an experiment or assessed in a mathematical equation is the dependent variable. The term “the result variable” is sometimes used to describe the dependent variable.
Reliant Variable the measurable variable that is dependent on other measurable things. As a result of manipulating the independent variable or variables in an experiment, these variables should change.
Therefore, In an investigation, the result is a dependent variable whose value is affected by changes in the independent variable.

The desert might seem like an unlikely place to find fish. There are long dry periods between rains when most surface water evaporates. Nonetheless, about 30 species of desert pupfish live in the American Southwest. Very hot water, unpredictable weather, high salt content, and predators are all sources of blank for the pupfish.
The answers are hormones, stress, response or homeostatis
Answer:
I think its homeostatis
Explanation:
Answer:
stress?
Explanation:
it isnt homeostasis or hormones or response
since it's a big change and extreme constant changes this seems like stress to the pupfish

Explanation:
took the test
Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.
Let us assume that following:
S=distance
U=initial velocity
V=final velocity
A=acceleration
T=time taken
Given that:-
S=2.5 km
S=2.5×1000 mtr
S=2500 mtr
T=12 seconds
V=180km/hr
=180×1000/3600 m/sec
V=50 mtr/sec
U=0 because in starting his car in rest position
Equation which use for calculations of acceleration,
S = UT + 1/2AT^2
2500 = 0×12 + 1/2A(12)^2
2500 = 0 + 1/2×A×144
2500 = 72×A
A = 2500/72
A = 34.72 m/sec^2
It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with 1 mole per dm3 sodium chloride solution.
The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.

because doorways are for earthquakes, radars wont do anything, and you dont run away from tornados. So the safest bet is to go in a bunker or basement.
A student likes to attend football games, no matter how cold and snowy the weather becomes. She is going to a game on a very cold day and takes along a hand warmer. She activates it and tucks it into the glove she is wearing. She holds her hands together, and before long, her hands are warm. Which best describes how her hands were warmed?
a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
b: Heat was transformed by convection, resulting in the conservation of energy
c: Thermal energy was transferred by currents, resulting in an increase in kinetic energy.
d: Heat was transformed by radiation, resulting in an increase in kinetic energy.
Answer:
The correct answer is - a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
Explanation:
Conduction is ne of the het transfer method where particular substance is heated and increase the kinetic energy which leads to the molecules to vibrate more and move or jump to the particles present in neughbouring substance and transfer some part of the enrgy.
This transfer is a continuous process untill both end become of same temperature of have same kinetic energy, In this case, heat is tranfer ffrom hand to gloves and to the other hand which are hold together after activating them.

Which of the following is one of the ways that cellular respiration and
photosynthesis are opposite processes? *
•Photosynthesis releases energy, and cellular respiration stores energy.
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration
puts it back.
•Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it
back.
•Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answer:
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
In this way it release the carbon dioxide back into atmosphere.
What two things can cause a DNA helix to separate into two strands
during PCR?
How do the strands separate during PCR? The DNA polymerase breaks the hydrogen bonds between the two strands. The primers separate the strands during the annealing step. The high heat of the denaturation step breaks the hydrogen bonds between the two strands.
The two things that can cause a DNA helix to separate into two strands during PCR are initiation and unwinding.
What is PCR?PCR is a polymerase chain reaction. The process is making more DNA sequences from a DNA sequence. The process is done in a PCR machine. The DNA template is put in the machine and a copy of the DNA is made.

Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. How will this affect the amount of co2 in the atmosphere?
As the Earth warms, scientists worry that some of the carbon in permafrost could escape to the atmosphere as carbon dioxide or methane. Increasing the amount of these gases in the atmosphere could make Earth's climate & more
Explanation:yw
The process of decomposition increases the amount of carbondioxide gas in the atmosphere.
The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.
This results in more warm temperature of the earth atmosphere so we can conclude that the process of decomposition increases the amount of carbondioxide gas in the atmosphere.

Pharyngolaryngectomy involves surgical excision of the hypopharynx and larynx, reported with codes 31390 or 31395, and these codes are differentiated based on with or without ______________.
Answer:
The answer is "Complications"
Explanation:
Pharyngolaryngectomy is an operation to eliminate/remove the larynx (voice box) and the pharynx (the territory at the rear of the mouth and throat). The activity is intense, requiring a general anesthetic and a stay of a little while in medical clinic. Now and then it should be completed in two phases, the subsequent stage being to revamp the structures in your neck however much as could reasonably be expected. This will expect unions to be taken from your chest, back or lower arm.
You should be offered broad pre-operative guiding in anticipation of the deficiency of your voice, in spite of the fact that it is conceivable to recapture a decent measure of vocalization with language instruction. After the activity you should inhale through an opening in your neck which will be a permanent feature.
