Answer:
im pretty sure it is underpopulation.
Answer:
I think it's B. survival of the fittest since it's mostly just a phrase people say. I don't think underpopulation because, I'm pretty sure that's used when there not enough of an animal in an area, so while it could be the answer I don't think it is. And overpopulation is used when there's to much of an animal in an area so like with underpopulation it could be the answer but I do not think it is. And Variation is a step in Natural Selection so that's definitly not it. So since Survival of the fittest is mostly just a phrase people say I think that's the answer. Sorry for wasting your time if I'm wrong.
How do fossil fuels affect the environment
Answer:
Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.

There are a number of similarities, and some differences, between the Q cycle in the mitochondrial electron transport system and the PQ cycle found in the chloroplast electron transport system. Sort the items into the appropriate locations, depending on whether they are unique to the PQ cycle, unique to the Q cycle, or common to both.The cycle converts a two-electron transfer process into two one-electron transfer processes.Two electrons are transferred from the reduced carrier to cytochrome c.Addition of electrons one at a time generates a semiquinone intermediate.Used to translocate protons across a membrane.Two electrons are transferred from the reduced carrier to plastocyanin.
Answer:
1. unique to the PQ cycle:
Two electrons are transferred from the reduced carrier to plastocyanin
2. unique to the Q cycle:
Two electrons are transferred from the reduced carrier to cytochrome c
3. common in both PQ cycle and Q cycle:
- The cycle converts a two-electron transfer process into two one-electron transfer processes
- Addition of electrons one at a time generates a semiquinone intermediate
- Used to translocate protons across a membrane
Explanation:
The Q cycle (Q due to quinol) refers to the cycle by which electrons are transferred from ubiquinol to cytochrome c. This cycle is associated with the sequential mechanism of oxidation-reduction between ubiquinol and ubiquinone, also known as Coenzyme Q10 (CoQ10, used as electron carrier), in order to move protons across the inner mitochondrial membrane. In the first phase of the cycle, ubiquinol attaches onto the cytochrome c oxidoreductase, also called complex III (because this complex is the third complex in the electron transport chain), in order to transfer two electrons to the complex. On the other hand, the PQ cycle (PQ due to plastoquinone) refers to the cycle where plastoquinone transports electrons during light-dependent photosynthetic reactions. In the PQ cycle, the plastoquinone serves as an electron carrier through the membrane of the thylakoid. In the first step of this cycle, plastoquinone obtains two electrons from photosystem II and absorbs two protons from the chloroplast stroma, resulting in plastoquinol, which subsequently transfers electrons to plastocyanin in a process coupled with the generation of a proton gradient between the lumen of thylakoid discs and stroma.

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).
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).

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.

Explanation:
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.

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.

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

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.

Explain how you found out that Lucy has ADA-SCID
Answer:
The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.
