Answers

They didn’t give you a word bank? It’s fine if they didn’t ill answer it either ways I’m just asking first

One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:

(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+

(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-

(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-

(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-

(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

I'm not sure if it is C or D ​

Answers

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.

A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean.The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year.



Is the city using its water supply in a sustainable manner?

A)yes
B)no

Answers

Answer:

B)no

Explanation:

Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.

The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.

This shows that people in the city are not using water sustainably which is causing a fall in precipitation.

Hence, the correct answer is "No".

Answer:

Pioneer species are established

A forest fire would represent the process of secondary succession.

In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.

Energy can be measured in calories, 1,000 calories is called a kilocalorie (kcal),
If the producers have 10,000 kcal of energy and 10% is transferred to the primary
consumers, how much energy is transferred?

100 kcal
1,000 kcal
10 kcal
Plz help me which one is it!!!!!

Answers

Answer: 1,000kcal

10% of 10,000 is 1,000.

The amount of energy transferred if 10% is transferred to the primary  consumers is 1000kcal

Given the following parameters

Amount of kcal the producer have = 10,000kCal

Percentage transferred to the primary consumers = 10% of the amount produced

Get the amount of energy transferred;

[tex]Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal[/tex]

Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.

Compare the Viking 1 and 2 probes to the Pathfinder probe that landed on Mars in 1997. How was their technology different?

Answers

Answer:

Explanation:

In 1976, The Viking 1 and Viking 2 probes landed on Mars. For six years they transmitted fascinating panoramic views of the red and rocky soil of Mars back to Earth. Twenty years passed before a third probe landed on Mars. In 1997, the Pathfinder probe landed a miniature vehicle named Sojourner on the planet. The probes operated for three months and sent back large amounts of data on the Martian environment. At the same time, the Mars global surveyor probe was placed in orbit to take an overall portrait of the planet. It supplied hundreds of thousands of bits of information, especially on climatic variations.

Answer:

Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.

Explanation:

Chloroplast absorbs sunlight also known as light energy used for the process of photosynthesis.

The observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.

PLANT CELL:

A plant is an organism whose cells contain organelles called chloroplast, which harbors chlorophyll pigment. This feature enables them perform photosynthesis; a process that plants use to synthesize their food.

Plant cells are eukaryotic in nature i.e. they contain a membrane-bound nucleus in their cells.

In addition to these organelles, plant cells also possess a cellulose-embedded cell wall that strengthens the cell.

Therefore, the observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?

Answers

Answer:

1. ATP will increase

2. NADPH will increase

3. Sugar will decrease

Explanation:

Had the same problem

The effect of temperature on these molecules are ;

ATP will increase NADPH will also increase  while Sugars will decrease

ATP (  Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.

NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.

Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.
