Explanation:

The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease.​ Thus, option D is correct.

The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8.The flow rate of the stream will decrease. The number of fish in the stream will increase and the number of fish in the stream will decrease.​

Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low and pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.

The animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die. From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.

Therefore, The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease.​ Thus, option D is correct.

Answer:

The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.

We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.

If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.

The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.

Explanation:

The relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

Psychrometer:

It is a device that use to calculate the relative humidity and dew. It has two thermometer, one measures the dry temperature while another measures the wet-temperature.

Given here,

Dry-bulb temperature is 26°C

Wet-bulb temperature is 18°C

The difference between temperature of wet and dry bulb is

= 26 - 18 = 8°C

Now compare the temperature difference to the chart given in the

Therefore, the relative humidity if the dry-bulb temperature is 26°C and the wet-bulb temperature is 18°C is 45.1%.

Answer:

Offspring will have some sort of genetic variation from parent (may be positive or negative or no effect,  based on the mutation type)

Explanation:

The reproductive cells pass on the traits from the parents to the offspring.

An organism that is mutated at a single DNA location in a reproductive cell, then that mutation will be passed on to the offspring.

Based on fact, that mutation will lead to some kind of effect in any trait, hence the same trait will be effected because of mutation in the offspring as well

It can also be said that offspring will have some sort of variation from parent (may be positive or negative or no effect,  based on the mutation type)

The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.

A = 27%

27 + 27 = 54

100 - 54 = 46

46/2= 23

Marshes and ponds describe the habitat of a frog. So, the correct option is D.

An area or place where an organism or a collection of organisms naturally lives and thrives is known as a habitat. It includes all the physical, biological and environmental elements necessary for growth and reproduction in a given place. A habitat can be any form of ecosystem, including a forest, desert, ocean, swamp, or dryland.

Temperature, precipitation, soil, vegetation, and other elements that are specific to each ecosystem affect what types of organisms can survive there. Other important elements of a habitat are access to food, water and shelter. Habitat theory is important to ecology and conservation biology.

Therefore, the correct option is D.
