correctly describe pH of a solution?

Answers

Answer 1
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of acidity or basicity of the solution. the letters PH stand for“power of hydrogen”and the numeral value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.

If the potential difference across a 30.0-ohm resistor is 10.0 volts, what is the current through the resistor?
O A 0.25 A
OB 3.0 A
OC 0.33 A
OD. 0.50 A

Answers

Answer:

C 0.33 A

Explanation:

The current through the resistor can be calculated using the formula;

V = IR

Where; V = Voltage (volts)

I = Current (Ampere)

R = Resistance (Ohms)

According to this question, I = ?, V = 10.0volts, R = 30.0ohms

V = IR

I = V/R

I = 10/30

I = 0.33A

Hence, the current through the resistor is 0.33A

identify 3 abiotic factors and their roles in the economy in your own words

Answers

Answer:

Abiotic factors are the non-living parts of the environment that have a major influence

on living organisms. They can help determine things like how tall trees grow, where

animals and plants are found, and why birds migrate. The most important abiotic factors

include water, sunlight, oxygen, soil and temperature.

Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All

living organisms need water. In fact, water makes up at least 50% of almost all living

things. Some organisms are made up of 95% water! Water is also essential because

other substances easily dissolve into it. This allows water to carry nutrients to cells and

wastes away from them. Without water, animals become weak and confused, and they

can die if they don’t get enough water. Think of how you feel after you take a long run.

Do you feel thirsty? This is your body signaling to you that you need water.

Sunlight is the main source of energy on Earth, which makes it an extremely important

abiotic factor. Sunlight is necessary for photosynthesis, the process where plants use

carbon dioxide (CO2) and water to make sugar – food for the plants that later becomes

food for animals. Without the sun, plants could not live, and without plants, animals could

not live! Sunlight is also plays a role in the production of oxygen and to an area’s

temperature, which are discussed in detail below.

Like water, oxygen (O2) is another important abiotic factor for most living organisms.

Oxygen is used by cells as an energy source. It gives cells the energy they need to carry

out important functions, for growth, and reproduction. Without oxygen, humans and the

other organisms that use oxygen would not be able to live! Oxygen is produced by green

plants through the process of photosynthesis, and is therefore directly linked to sunlight.

Soil is considered an abiotic factor since it is mostly made up of small particles of rock

(sand and clay) mixed with decomposed plants and animals. Plants use their roots to get

water and nutrients from the soil. Soils are different from place to place – this can be a

big factor in which plants and animals live in a certain area.

Temperature is an abiotic factor that is strongly influenced by sunlight. Because the

amount and strength of sunlight varies by location, the earth’s surface has different

temperatures in different zones. While some animals and plants can bear extreme heat

or extreme cold, others can only survive well in moderate temperature ranges. In fact, all

plants and animals are adapted to survive between a minimum and maximum range of

temperatures. For example, a penguin from the polar region couldn’t live in a 110°F

desert. It would be too hot! Temperature, then, helps to influence which plants and

animals can live in an area.

D

Answers

Answer:

C. Net Primary productivity

Explanation:

In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.

The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R

Where, R = energy lost via respiration.

ATP can convert to ADP during ___________.

Answers

Answer:

phosphorylation

Explanation:

ATP usually releases energy by breaking down the weak phosphate cell present.  The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.

A

Explanation:

That is the only option that can be an experiment and conduct research to answer.

The option that reveals the scientific question is as follows:

How does the release of heated water from a power plant into a river affect the native population of fish?

Thus, the correct option is A.

What is a Scientific question?

Scientific questions may be defined as questions that may direct to a hypothesis and assist us in answering or figuring out the reason for some observation.

This specific question clearly determines the effect of heat water from a power plant on the native population of fish with respect to the controlled environment that receives the normal and fresh water for the fish population.

The rest of the options are significant for analysis but do not contain more accurate and valid scientific questions in order to predict some outcome with respect to the hypothesis.

Therefore, the correct option for this question is A.

Heterotroph

Explanation:

They require other sources to sustain themselves and cannot produce their own energy.

Answer:

Heterotrophs

Explanation:

Producers are the most common type of autotrophs because they are able to make food out of energy and any other materials they happen to find or lie upon. Humans cannot create food from energy because they are not producers.

Heterotrophs are organisms that eat consumers or producers. A human can eat other consumers (meat/omnivore) and eat plants (producer) like lettuce or kale.

A biome is a large, recognizable geographic area that is home to a variety of ecosystems and communities of plants and animals that have evolved in a particular environment, including climate, soil, and topography. Temperature, rainfall, altitude, latitude, and the types of plants that grow there are used to identify biomes.

Aquatic biomes such as tundra, taiga or boreal forests, temperate deciduous forests, tropical rainforests, grasslands, savannas, deserts, and marine and freshwater habitats are just a few of the primary categories of biomes. Each biome has a different set of traits and characteristics that influence the types of plants and animals found there.

Therefore, match each biome with the correct description.
