A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
2. The experiment proceeded as normal, with the experimental group hearing about the
potential presence of a gun as the confederates left the study and the control group not
hearing about the gun. All participants returned on day two for the interview with the
police detective. After debriefing, none of the participants said they were aware that the
theft was staged. The researchers found that those in the experimental group did
incorporate the gun misinformation into their memories of the theft more than those in
the control condition. That is, the mean score that a gun was present was much higher for
the experimental group (M= 67%, SD = 12.4%) than the control group (M= 33%, SD =
11.16%).

how quickly the body parts regenerate
how similar salamanders are to humans
which body parts are most often lost
which genes control regeneration
Answer:
The answer could be:
(/) which genes control regeneration
(/) how similar salamanders are to humans
(x) how quickly the body parts regenerate (salamanders' size and form does not equate to human beings)
(x) which body parts are most often lost (it was already given that it's legs and limbs)

Explanation:
Is water renewable or non-renewable?
yes or no?
explain:
Answer: yes.
Explanation: Non-renewable resources can be depleted and cannot be replenished. Water is a natural resource which is not only found on the surface of the earth in rivers, oceans, lakes, and streams but also underground. Water is a renewable resource.
Q: Predict and describe some possible effects to your entire food web if the following happened:
A mysterious virus has sickened the secondary consumer fish. There
are few survivors. Fortunately, this virus is not affecting organisms on any other trophic levels. However, the loss of these organisms is
affecting the rest of the food web. Please describe the possible effects:
Answer:
Less fish will disrupt the predators in the ocean. Sharks, and other predators in these oceans need a food source such as fish if this Virus does indeed kill these many fish. Meaning the virus is in this fish, It might spred to predators that eat these fish. Still if the predators of the food chain dont find these food sources for them i am sure they will die of starvation.
Explanation:
If a food source for animals is obsulete i am sure the predators of the animals will have starved to death like how, the Hot blob is affecting the Cassins auklet due to the Less amount of phytoplankton in the oceans.A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.
Answer:
The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.
Explanation:
Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.
They are found to be very ardent and quicker at recycling natural waste than animals and plants.
Without adequate moisture, Millipedes can die within 48 hours.

factor.
Answer:
Increasing carbon dioxide concentration increases the rate of photosynthesis as carbon dioxide (CO2) is a limiting factor.
Explanation:
Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.
The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen

How many valence electrons does Neon have and does it have cations and anions???
Answer:
Neon has eight valence electrons and it does not have cations or anions.
Explanation:
Neon is a noble gas, meaning it has already fulfilled the octet rule and has eight electrons in its valence electron shell. Hence, it does not want to lose or gain any more electrons, and does not have cations or anions.
Hope this helped!
Answer:
Neon has eight valence electrons and it does not have cations or anions.

Describe the way convection works and how it might work within the earth? -geology question
Answer:
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
Explanation:
what is the difference between phenotypes and genotypes
Answer:
Phenotype are physical traits a organism can inherit for example color, height, or body features are phenotype. Genotype are genetic traits that can be inherited for example personality, or behavior traits. So the primary difference between phenotype and genotype is that "phenotype are psychical characteristics while genotype is genetic."

Long bones are those that are longer than they are wide. The end of the long bone is the epiphysis and the shaft is the diaphysis. When human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum
9. What type of bond is pictured in the image below?
a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond
ONLY 9
Answer:
c. metallic bond
Explanation:
Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.
The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:
