Answer:
Rise in temperature.
Explanation:
Increase in temperature is responsible for the decline in the population of trout because trout needs low temperature for better growth and survival. Due to more consumption of fossil fuels in vehicles and industries, more carbondioxide gas is released which causes air pollution. This air pollution increases the temperature of the earth surface known as global warming due to which the cold areas become warm and as a result the trout population decreases.

Explanation:
(PLEASE HURRY)Strong winds blow sand to a new location, and some of the sand forms a sand dune. The first plant species to live in the new habitat of the sand dune is a type of grass. This grass stabilizes the sand dune. Over time, the sand dune grows larger and soil forms on the surface. As these changes occur, different plant species become dominant.
Why doesn't the original grass remain the dominant plant on the sand dune?
A.
The grass cannot reproduce fast enough to cover all of the growing dune.
B.
New plants are better suited to the new conditions in the sand dune habitat.
C.
The grass moves to new sand dunes to start the succession process again.
D.
New animals come to the new sand dune habitat and eat the grass.

D. a spider and a cockroach
B. would be the answer.
I hope this helps
A pair of human mother and her child belongs to the same population.
What is population?"Individuals of any species live in groups in a well defined geographical area, share or complete for similar resources, potentially interbreed and thus constitute a population."A dog and a cat, a marigold and a geranium and a spider and a cockroach do not share similar resources and they don't interbreed so they do not belong to the same population.
Hence, the correct option is C. a human mother and her child.

How do plate tectonics support evolution?
An experiment is designed to compare the effects of glucose and sucrose on the osmoticpotential of a model cell. Two dialysis bags are used, one filled with a solution of 5% by massglucose and the other with a 5% by mass sucrose solution. A given membrane is permeable towater but impermeable to glucose and sucrose. Each membrane bag is then placed in a beaker ofdistilled water for two hours. The change in mass of the glucose bag is recorded below.Solution (5% by mass) Initial Mass ofSolution andMembrane Bag (g) Final Mass of Solutionand Membrane Bag(g)Glucose in DistilledWater 10.0 13.2Sucrose in DistilledWater 10.0 ?I got this question incorrect because I said the glucose would pass through the semipermeablemembrane, however, it would be the water that passes through. One way I can prevent myself.
Answer:
i dont understand you're qiestion
Glucose can pass through the semi permeable membranes where the molecules can pass because they are soluble in water enough. The molecules can pass through because of the solubility factors.
What is a semi permeable membrane ?It is the semi permeable membrane where the half of the molecules get passed through the membrane. The molecules are selectively present.
Cell membranes are an example of semi-permeable membranes. Cell membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through, but do not allow larger molecules like sucrose, proteins and starch to enter the cell directly.
Transport is helped by certain molecules as well where the few of the ions, channels and the molecules are taken up by the membrane through the selected transportation of the ions.

(4pts) Drugs, medicines, and poisons often work by acting on endogenous proteins. They do this by looking similar to a signal molecule and binding to the endogenous protein. Look up these four examples to fill in this chart. Drug, medicine, or poison Looks similar to this endogenous molecule: Binds to this endogenous protein/receptor: Muscarine Acetylcholine muscarinic receptors Prozac Serotonin serotonin transporter protein Ketamine NMDA NMDA receptor Tamoxifen estrogen estrogen receptor
Answer:
Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors
Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor
Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein
Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor
Explanation:
Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.
Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.
Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.
Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.

What is the manipulated variable in this experiment?
O A. The distance the snails moved
OB. The size of the petri dishes
C. The temperature of the water
D. The number of snails observed HELP ME
The correct answer is C. The temperature of the water
Explanation:
In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.
PLEASE HURRY,(GIVING BRAINLIEST) (THE ACTUAL SUBJECT IS SCIENCE)After a major forest fire kills all of the plants in an area, the first plants to grow in the burned area are often types of grass. Because they are the first thing to grow in the new ecosystem, these types of grass are called pioneer species. What adaptations would help the grass be a successful pioneer species?
A.
slow reproduction and the ability to grow in sunny places
B.
rapid reproduction and the ability to grow in sunny places
C.
slow reproduction and the ability to grow in shady places
D.
rapid reproduction and the ability to grow in shady places
Answer: B
Explanation:
To help the pioneer species to grow, it needs to have rapid reproduction. But, it also needs the sun to grow very well. If it does not have the Sun, it will most certainly die and be endangered in the area. The answer is B, we need both rapid reproduction and the Sun.
Answer:
rapid reproduction and the ability to grow in sunny places
Explanation:
After a major fire, less sunlight is blocked by trees and other plants. Plants that can use the increased sunlight are more likely to thrive in the new environment. Rapid reproduction would help a plant species to spread more quickly to take advantage of the resources and lack of competition. Therefore, the adaptations that would help grass be a successful pioneer species are rapid reproduction and the ability to grow in sunny places.
