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.
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.

difference between mycoplasma and l form bacteria
Answer:
L-form bacteria are distinct from mycoplasmas, because Mycoplasma spp. do not originate from bacteria that normally possess a cell wall. ... Some of these bacteria remain as CWDB (stable L-forms), whereas others revert back to possession of a cell wall (unstable L-forms).

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
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
Explain how fossil fuels are formed from living organisms on land and in sea.
When farmers clear a forest and plant crops, how will the biodiversity of the land be affected?
The biodiversity will decrease with higher populations of fewer species,
The biodiversity will increase with lower populations of more species.
The biodiversity will decrease with lower populations of more species.
The biodiversity will increase with higher populations of fewer species.
Answer:
The biodiversity will decrease with lower populations of more species.
Explanation:
This is because clearing a forest destroys habitats and therefore kills animals as they have no shelter, no food source and no water source.

5) If a body cell contains 50 chromosomes, how many
will exist in its gametes?
25
Answer:
25
Explanation:
gametes are haploid cells and body cells are diploid. when a diploid cell undergo meiosis it will produce haploid gametes with half number of chromosomes. in this case body cell has 50 chromosomes so their gametes have only 25 chromosomes.

SC.912.L.14.1
All cells come from parent cells that exchange DNA.
All living things are composed of single cells or multiple cells.
All cells grow and develop until they reach a certain size, at which point they die.
All cells are equipped with structures that enable motion, such as pseudopods or flagella.
All living things are composed of single cells or multiple cells. Therefore, option B is correct.
What is cell theory?Cell theory is given by Schleiden and Schwann. According to this theory, cells make up every biological entity; they are the basic building block of life, and all life originates from earlier forms of life. Today, the cell idea has become one of the guiding concepts of biology due to its widespread acceptance.
A cell is the lowest form of life. This indicates that a cell cannot be divided into smaller units and yet be considered to be alive. An entire organism, such as a person, can be divided into smaller parts, such as organ systems, organs, and tissues.
Organisms can be unicellular or multicellular. Therefore, option B is correct.

What type of microbe is used in a vaccine .
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

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