What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply.
a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

b.) A special enzyme produces more H+ ions.

c.) Photons of light create more H+ ions.

d.) The photolysis of water releases H+ ions into the thylakoid space.

Answers

Answer:

a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

d.) The photolysis of water releases H+ ions into the thylakoid space.

Explanation:

The thylakoid, which is found in the chloroplast, is the site of the first stage of photosynthesis (LIGHT DEPENDENT STAGE) in the cells of plants. The light stage of photosynthesis functions to produce energy (ATP) and NADPH for the second stage called Calvin cycle.

However, this ATP is generated by the power realized from the pumping of Hydrogen ions (H+) into the thylakoid lumen. The following causes the build up of H+ ions in the thylakoid space:

- Light photon hits the chlorophyll molecule, which is the photosynthetic pigment, to become charged. The electrons (e-) generated from this provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

- Photolysis of water, which involves the splitting of water to produce hydrogen ions (H+) causes a build up of H+ in the thylakoid space.

discuss the contributions of pasteur, and koch to 'germ theory of disease' and to the prevention of diseases​

Answers

Answer:

Pasteur showed that putrefaction is a process associated with organisms present in the air, while Koch identified the germs that cause different diseases

Explanation:

The germ theory states that pathogenic microorganisms called germs cause the disease state observed in a particular (infected) organism. The term 'germ' includes pathogenic bacteria, protists, fungi, and even non-living pathogens (e.g., viruses). This theory was developed and accepted due to the work of Louis Pasteur and Robert Koch. In the 1860s, Pasteur showed that germs were omnipresent in a flask open to the air, showing that putrefaction and fermentation are caused by these microorganisms. Moreover, in the 1880s, Koch identified the germs that cause different diseases, including tuberculosis (Mycobacterium tuberculosis) and cholera (Vibrio cholerae).

How are we able to tell from the results of this blood type test that this is 0+

Answers

Answer:

there's no test so... The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

How many grams of starch would you need to make 500ml of a 5% solution?

Answers

Answer:- 25 grams.
Solution:- We are asked to make 500 mL of 5% glucose solution. The percentage is the mass by volume percentage. 5% glucose solution means 5 grams of glucose present in 100 mL solution. From this given information, we can easily calculate the mass of glucose required to make 500 mL solution.
The calculations are shown as:

500mL*5g/100mL

= 25g
So, 25 grams of glucose are required to make 500 mL of 5% solution.

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans to arrange the fossils in display cases so that each case contains the same number of fossils. Also, each case must contain fossils from only one period. What is the largest number of fossils that can be placed in each case

Answers

Answer:

4

Explanation:

Number of fossils collected over period 1:

400

Number of fossils collected at a later period :

204

For each display case to have the same number of fossils ; the greatest number of fossils possible per case:

Obtain the greatest common factor of both 400 and 204

400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102

Hence, the greatest common factor (400 and 204) is 4

Hence, the greatest Number of Fossil possible per case = 4

Which statement is correct?
A.
All organisms that can synthesize their food by means of photosynthesis are heterotrophic.
B.
All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
C.
All organisms that cannot synthesize their food by means of photosynthesis are heterotrophic.

Answers

Answer:

B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

Explanation:

There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
