Answer:
All
Explanation:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
Answer:
D
Explanation:
ATP is created in the ETC
Water is formed as a by product
The concentration gradient is what fuels the ETC. Protons (H+ ions) move across the membrane to create energy.

Summarize how the overharvesting of a single species,such as baleen whales,can affect an entire ecosystem.
Answer:
Overharvesting can have a negative impact on an entire species because it can alter food web relationships. For example, if there are too many whales, many organisms may lose their food source and homes, or even worse, go extinct!Source:

It is a barrier that allows materials to move freely from one side to the other.
It is a barrier with tiny openings that let some, but not all, materials pass through.
It is a barrier that helps materials move from one side to the other.
Answer:
C
Explanation:
Semi means partly
permeable means allowing liquids or gases to pass through it
Semipermeable means allowing some, but not all, liquids or gases to pass through it.
Answer:
c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Explanation:
The prefix "semi-" means "some; partially". "Permeable" means "allow to pass through". Using your knowledge of the purpose of the membrane and the meaning of the word "semi-permeable", you would use context to come to the conclusion that the correct answer is c) It is a barrier with tiny openings that let some, but not all, materials pass through.

How does 02 enter the mitochondria
How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.
Which macronutrient promotes root growth?
Answer: Phosphorus (P)
Explanation: Phosphorus is one of the important macronutrients of plants which promotes the plant root growth.
Phosphorus in good amount would lead to -
• Extensive roots
• Fewer shoots
• Stunted growth
Whereas if the plant deficits Phosphorus then it would lead to
• Poor root growth
• Few flowers or aborted flowers
• No fruits
The greatest number of relationships between the
organisms in an ecosystem is best shown in
A. a food chain
B. an energy pyramid
C. a food web
D. an ecological succession diagram
The greatest number of relationships between the organisms in an ecosystem is best shown in a food web. Thus, the correct option is C.
What is a Food web?A food web consists of all the food chains which are present in a single ecosystem. Each of the living thing in an ecosystem is a part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
For example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. It is a food web that shows the many different paths plants and animals are connected.
Therefore, the correct option is C.

Environmental degradation must be reduced, so by the baseline data of the world's ecosystem must be researched.
What is the world's ecosystem?Ecosystem defines the interaction between living (biotic) components and nonliving (abiotic) components. A living system depends on nonliving factors around them.
Temperature, soil, and light are all components that are necessary for the living system to reproduce and survive. Plants can not do photosynthesis without light and also get minerals and water from the soil.
We need to understand the baseline of the world's ecosystem, so climate-changing conditions can be reduced. Global warming is a critical condition for the ecosystem and can be reduced by research.
Therefore baseline data on the world's ecosystem must be researched to improve environmental conditions.

Which statement about US greenhouse gas emissions is supported by the bar graph? Emissions decreased every year between 2005 and 2014. Emissions increased substantially between 2005 and 2014. After peaking in 2007, emissions dropped every year through 2014. After peaking in 2007, emissions went up and down through 2014.
Countries often have records of gas emissions in their county. The statement about US greenhouse gas emissions is supported by the bar graph is that after peaking in 2007, emissions went up and down through 2014.
Greenhouse gas emissions often takes place due to the activities of human. These activities acts as a catalyst to powerup the greenhouse effect, causing climate changes.Recorded data of gas emissions has shown that after it peaked in 2007, reduction is said to be of averaged 1.3% per year but the data of U.S. energy-related CO2 emissions in 2019 shows that it was 1.8% greater than in 1990.

Which of the following choices is not among the most common cell shapes found in prokaryotes?
оооо
Cocci (spherical)
Bacilli (rod-shaped)
Spirochetes (spiral-shaped)
Recticuli (rectangular)
Answer:
Recticuli(rectangular)
"Recticuli (rectangular)" is not among the most common cell shapes found in prokaryotes. Therefore, option (D) is correct.
Rectangular cells, represented by "Recticuli" in your options, are not among the most common cell shapes found in prokaryotes. Prokaryotes are primarily characterized by cocci (spherical), bacilli (rod-shaped), and spirochetes (spiral-shaped) forms. Cocci are typically round, bacilli are elongated rods, and spirochetes exhibit a spiral or helical structure.
These shapes facilitate various functions such as movement, attachment, and replication. Rectangular cells, while theoretically possible, are not commonly observed in natural prokaryotic populations. The lack of real-world prevalence could be attributed to the structural challenges and limited advantages of such a shape in prokaryotic environments. The prevailing shapes have likely evolved due to their practical benefits, underscoring the connection between form and function in these microorganisms. Therefore, option (D) is correct.

What is Light-Reaction takes place during Photosynthesis?Autotrophic plants produce their own food through a process called photosynthesis. Sunlight, chlorophyll, CO2, and water are four crucial components needed for this process. It is a response that is light dependent.
In plants and some other creatures, a process known as the "Dark Reaction" harnesses the energy from the sun to change carbon dioxide and water into glucose (a sugar) and oxygen.
Therefore, a sequence of chemical events known as the "Light Reaction of Photosynthesis" are what is needed for the pigment found in leaves, such as chlorophyll, to transform light energy into chemical energy in the form of ATP and NADPH.
