Answer:
Substances can move from areas of low concentration to high concentration.
Explanation:
For the first one, substances CAN move in and out of cells in an active transport.
As for the second one, active transports do require energy. That is what makes them "active" and sets them apart from passive transports which don't require energy.
Lastly, substances can move across a membrane regardless of if they are water soluble (such as lipids, or fats that the cell does not use. Think of it as a way for the cell to eat, drink, and defecate or remove waste.)

Prokaryotic and eukaryotic cells have several differences. Which statement below is not one of those
differences?
Prokaryotic cells are found in the domains Eubacteria and Archaea.
Eukaryotic cells have organelles for processes like respiration or photosynthesis.
Prokaryotic cells cannot make their own proteins.
Eukaryotic cells are generally ten times larger than prokaryotic cells.
Answers
prokaryotic cells cannot make their own proteins, the statement is false. Thus the option C is correct.
What are the distinguishable features of prokaryotes and eukaryotes ?Prokaryotic cell are unicellular as it is made up of single cell and the size ranges from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular, the size ranges from 10 μm – 100 μm in diameter.
cell wall is present in prokaryotes which involve in providing protection of the cell where as only in plant cell wall is present; True Nucleus is absent in prokaryotes instead of nucleus, nucleoid is present which carry genetic material while in eukaryotes true nucleus is present.
The Ribosomes are Smaller in size and 70s type in prokaryotic cell where as the ribosome is larger in size with 80s type in eukaryotic cell larger in size and linear shaped ribosomes are present.
All the metabolic and physiological activities occur in a single cell of prokaryotes where as the metabolic and physiological activities occur in different organelle.
Thus the option C is correct.

______structures are fully functional, show evidence of a common ancestor, and may or may not have
the same function in different species.
Answers
Answer:
Homologous
Explanation:
Homologous structures are similar organs or structures that are found in different animals that suggest they come from a common ancestor. This is evidence of evolution.
The structures might not necessarily look identical and might not perform the same function. For example, the flippers of a dolphin, the wings of a bird, the legs of a dog, and the arms of a human are considered homologous structures.

Answer:
Explanation:
attempted to control their population growth
The fact that people have historically prioritized short-term benefits above long-term sustainability is a significant factor in how severely humans have impacted the ecosystem.
Thus, human actions like deforestation, pollution, overfishing, and the burning of fossil fuels have historically been motivated by short-term economic or resource requirements without taking the long-term effects on the environment into account.
The stress on ecosystems and natural resources has grown due to population expansion and rising demand. Unsustainable practises, insufficient regulation, and a lack of awareness have all contributed. To solve these problems, we need to adopt more environmentally conscious behaviors by raising public knowledge of environmental issues.

1 poin Students are discussing what they know about cellular transport. Their explanations are displayed in the table. Which student(s) gave an accurate statement regarding cellular transport? * EXPLANATION Passive transport is the movement of molecules from high to low concentration. 2 The sodium-potassium pump is an example of active transport because it uses energy 3 Molecules move against the concentration gradient in passive transport. 4 Diffusion and osmosis are both examples of passive transport. O Student 1 only O Students 1 and 2 Students 1, 2, and 4 O Students 2, 3, and 4
Answers
Answer:
Students 1, 2 and 4
Explanation:
Passive transport goes from the higher concentration to the lower concentration in favor of the concentration. Student 3 referred to this as active transport and that is not right.
Simple passive diffusion, facilitated diffusion (via channels and carriers), and active transport are the fundamental forms of membrane transport. A bilayer membrane requires energy to flow through, even with simple passive diffusion. Thus, option C is correct.
What are the cellular transport mechanism in cell?The molecules will migrate from a lower concentration to a greater concentration during active transport.
Energy in the form of ATP is needed for this cellular transport molecule to function. Based on their purpose, the active cellular transporters are divided into four categories.
The sodium-potassium pump in the human body serves as a practical illustration of active transport. Here, potassium ions remain inside the cell while sodium ions are outside the cell.
Therefore, Exocytosis, endocytosis, antiport pumping, and symport pumping are the different types of active transporters.

What hypothesis was validated by using paleo-magnetism?
Question 8 options:
a) subduction
b) hot spots
c) seafloor spreading
Answers
Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.
