Explain where the enzymes for electron transport are located in bacteria (prokaryotes) if they don't have internal membranes, and therefore do not have a mitochondria
In bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.
Bacteria lack mitochondria, i.e. bacteria have no membrane-bound organelles.
In consequence, bacterial enzymes responsible for the electron transport chain are localized in the plasma membrane.
The electrochemical proton (H+) gradient required to create Adenosine triphosphate (ATP) from ADP and phosphate (Pi) is generated across the plasma bacterial membrane.
In bacteria, the electron transport chain is generally shorter and contains a lower phosphorus-oxygen ratio than the mitochondrial (eukaryotic) electron transport chain.
In conclusion, in bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

Fossil fuels are preserved remains of animals and plants. They record documents of diversity of life forms. Paleontologists are people who study about fossils.
What are fossils?Fossils are decomposed plants and animals. They can be the preserved remains or traces of living things. Thus the first statement is correct. The second statement that they record documents the diversity of life forms is correct since, by studying fossils we can find which types of living things were there in an area.
The people who study on fossils are called Paleontologists. The fossil formed when an animal walked in mud long ago and then the mud hardened into rock is an example of trace fossils. Most fossil are found in sedimentary rocks.
Fossils tell about both land and water plants and animals. A paleontologist finds a fossil of a fish on a mountain. She can infer that the area was once underwater. Not every but most dead animals and plants form fossils.
No condition can change chemical molecules of a fossils into that in living cells. The oldest rocks contains both complex and simple organisms. Thus the statement is true.

A geyser shoots water and steam out of the ground. The hottest geysers heat steam to temperatures of 200°C or higher.
Volcanoes, geysers, and hot springs all provide clues about Earth's interior. They also show one of the ways that Earth's layers interact with each other.
1. What do you predict Earth's interior is like? How do its rocks compare to rocks on the surface? Cite evidence that supports your prediction.
The rocks are comparable to the surface because they are almost certainly metamorphic rock, which is supported by the fact that magma will melt and combine various types of rocks.
What geysers, hot springs, provide clues to Earth's interior?Hot springs and geysers are likewise created by heated underground water; hot springs are more frequent than fumaroles, while geysers are less frequent.
Geysers are created by a surface hole in the Earth's crust that stretches far below the surface. Water is put within the tube. Magma, which is molten rock towards the tube's bottom, heats the water there. Water in the lower portion of the tube near the magma gets extremely hot.
Therefore, Due to their sophisticated plumbing systems, geysers can be recognized from both hot springs and fumaroles, whereas a hot spring and a fumarole differ only in their level of warmth.

What is an ecosystem and what are its parts and functions?
What can challenge an ecosystem?
What are the roles of the water and food cycles in an ecosystem?
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.

science stuffs lol this is about diffusion, osmosis and equilibrium
Answer:
Osmosis causes water to move toward the stronger concentration
Explanation:
In this system, there is a semipermeable membrane. Since the particles of solute (the black dots) are only on the left side, this means water can move across the membrane, but the solute can't. So, the water moves to dilute the stronger concentration because of osmosis (i.e. moving from high water concentration/low solute concentration to low water concentration/high solute concentration). The water would keep moving until the concentrations on both sides of the membrane are equal.

Plz will be marked BRAINLIEST and thanks
Answer:
As we can see from the graph above, brightly colored guppies would only survive in environments without predators, as they have worse camoflague thanks to their bright tail fins. In an environment with predators, guppies with plain/not brightly colored tail fins would survive better, seeing how while even placed in the predator's sight the guppies were less likely to be attacked when not brightly colored.
The discovery that the moon is similar in composition to the outer portions of the earth most supports the
theory.
synchronous
capture
impact
co-formation
Answer:
It most suppoet tge impact theory.
Explanation:
The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.
Answer:
Impact Theory
Explanation:
"The Impact Theory has two advantages over other theories about the moon's origin. First, other theories cannot explain the differences in the composition of the earth and moon. . . If Earth and a Mars-sized object collided, their iron-rich cores most likely would have merged into the earth's core. The collision would eject dust primarily from the mantles of the two bodies. This would explain why the moon's composition is similar to the composition of Earth's mantle."
The co-formation theory is not supported by that discovery because its composition should have been the same. "Although the moon is similar in age to Earth, its composition is very different. Earth is 31% iron, with most of the iron contained in the earth's core. The moon is only 8-12% iron. This difference is hard to explain if the earth and moon formed from the same material."
Therefore, it is not the co-formation theory, it is the impact theory.
Which description is evidence for the theory of plate tectonics but does not suggest that the continents were once connected?
A. matching rock layers on separate continents
B. Thin layer of sediment covering the ocean floor, indicating that it was relatively young
C. Similar land features on separated, present-day continents
D. The interlocking of present-day coastlines, such as Africa and South America
Answer:
B I think, but I may be wrong, the reason for my answer is because a suggests similarities, C suggests similarities and so does D partially suggesting they may have been connected
The description is evidence for the theory of plate tectonics but does not suggest that the continents were once connected in the interlocking of present-day coastlines, such as Africa and South America. The correct option is D.
What are tectonic plates?
The most convincing proof that the two continents were formerly connected is the existence of identical fossil species along the South American and African coasts.
Because plate tectonics involves separate portions of the earth's crust and tectonic plates result from the descent of items and processes, the two are distinct.
Africa and South Africa were once a single land, but they drifted due to the breaking of this land, they can fit into pieces as a jigsaw puzzle.
Therefore, the correct option is D. The interlocking of present-day coastlines, such as Africa and South America.
