Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

Which of the following problems are environmental indicators of acid deposition?
Decreased pH levels in lakes and rivers
Decreased concentration of aluminum in the soil
Changes in development of indicator organisms of an ecosystem
II only
III only
I and III
I and II
Answer:
I and III
Explanation:
Acid deposition will decrease pH levels in lakes and rivers since it contaminates them and lowers their pH, and organisms may be affected by the increased acidity in their immediate surroundings, but aluminum has nothing to do with pH levels at all.
Hope thish elped!
Option I and III shows the problems of environmental indicators of acid deposition.
The following information should be considered:
The acid deposition should reduce the level of pH in terms of lakes and rivers as it contaminates also the organisms should impact when the acidity should be increased for the surroundings. But the aluminum does not have any relationship with pH levels.Therefore we can conclude that options I and III are correct.

Ball and socket joints allow bones to move _____.
back and forth
in all directions
across each other
up and down
Answer:
in all directions
Explanation:
Your shoulder is a ball and socket joint and it can move in all directions as an example.
Answer:
B.) in all directions
Explanation:
Ball-and-socket joints are as the name implies. A ball-shaped end of bone attaches to an indentation on another, the socket. It rotates around in any direction, with an example being the end of your arm that attaches to your torso. This design makes it more mobile than any other type of joint.
Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.

Why can light microscopes produce images in their natural color, while scanning electron and transmission electron microscopes only produce grayscale images?
Answer:
there's no color info recored
Explanation:
Answer:
The reason is pretty basic: color is a property of light (i.e., photons), and since electron microscopes use an electron beam to image a specimen, there's no color information recorded.

4. Choose the microscopy technique that would best fit the needs of each scenario.
Scenario 1: Scientists are attempting to identify the specific type of leukemia a person has based on cell surface structures. ___
Scenario 2: Researchers are studying chemotaxis in white blood cells. Chemotaxis is the movement of living cells in response to a particular substance. ___
Scenario 3: Cell biologists are interested in measuring the distance between the inner and outer nuclear membranes, and need an instrument capable of producing images where the tiny distance between these two membranes is clear. __
Answer: Scenario 1: SEM
Scenario 2: Light
Scenario 3: TEM
Explanation:
The technique applied to observe and analyze objects that cannot be seen with the bared eye is called the microscopic technique.
1. The technique used will be SEM. A scanning electron microscope (SEM) is used to generate an image on the individual surface with the help of electron lasers.
It is useful in apprehending cell surface fabrication and topography.Therefore, to study the cell surface structure of leukaemia SEM is best.2. The light microscopy technique can be applied to study chemotaxis.
When there will be a movement in the living cell due to response towards chemical then the light microscope can be used to visualise the cells.Therefore to study chemotaxis light microscopy should be employed.3. The transmission electron microscope (TEM) method can be used to know the gap between the inner and outer layers. They are used for observing very thin segments of specimens.
Through the thin fragments, the electron flows easily and the image is produced.Therefore, TEM should be used by scientists to measure the distances.To learn more about the microscopy techniques follow the link:

A
cellular respiration.
B
reproductive cycle.
C
nitrogen cycle.

3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.

question
A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2
Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.
In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.
