Chemosynthetic organisms are considered autotrophs
Option A
What is chemosynthesis?It is a a special type of autotrophic nutrition whereby organisms use chemical energy to produce their own food by themselves.
In this case, chemosyntyethic or autotrophic bacteria produce their food using chemical energy
What are autotrophs?Autotrophs are organisms that produces their food by themselves either through photosynthesis or chemosynthesis

Passive transport is the movement of molecules across a membrane without the use of energy. Why causes the molecules to move?
Molecules move inside a cell to interact with organelles.
Molecules move across a membrane to reach other cells.
Molecules move from an area of relatively low concentration to an area of higher concentration.
Molecules move from an area of relatively high concentration to an area of lower concentration.
PLEASE ANSWER RIGHT!!!!!
Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.

How is a gill adapted for gas exchange?
Answer:
The exchange surfaces in fish are gills . Exchange of gases in fish is very efficient because of: the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell thick.Explanation:
Could there be a frameshift mutation that would not affect the
structure and function of the resulting protein? Explain your
answer.
Answer:
no, because it would have to be a perfect process, and changing would end in a mistake.
Explanation:
(detail) It would be unlikely, because a frameshift mutation shifts every nucleotide down one, so several amino acids in the protein are likely to be changed. However, if a frameshift mutation occurred near the end of the DNA sequence, the protein could have minimal changes to its structure and function.
It is possible the emergence of a frameshift mutation that does not affect the structure of a protein, but it will invariably modify its structure.
What is a mutation?A mutation is any alteration in the genetic material (DNA) that forms the genome of an organism.
A frameshift mutation can be defined as a mutation that modifies the Open reading Frame of a given gene.A frameshift mutation can be caused by deletions or insertions (indels) in the resulting DNA nucleotide sequence.In conclusion, it is possible the emergence of a frameshift mutation that does not affect the structure of a protein, but it will invariably modify its structure.

In 1827, a botanist named Robert Brown observed pollen grains that moved randomly when in water. At the time, he just didn't know how to explain why the grains moved randomy and not in a particular direction.
Later in 1905, Albert Einstein explained that the grains moved randomly due to individual water molecules colliding with the pollen grains. This provided evidence that molecules did exist and contributed to the particle theory.
(Particle theory is a theory that explains properties of solids metals and gases. It also involves the arrangement and movement of particles, which can help with studying movement of air particles)

Which type of microscope provides tremendous (100,000-fold) magnification and enables viewing of fine internal structural details of cells
The type of microscope that provides tremendous (100,000-fold) magnification and enables viewing of fine internal structural details of cells is transmission electron microscope. The correct option is C.
What is transmission electron microscope?Transmission electron microscopes (TEM) are types of microscopes that provide an image that is greatly enlarged while viewing specimens using an electron particle beam. TEMs have a 2 million-fold magnification capacity.
The primary distinction between SEM and TEM is that the former produces images by detecting reflected or knocked-off electrons, whereas the latter produces images by using transmitted electrons (electrons that are travelling through the material).
Many of the same optical principles that govern the operation of the light microscope also apply to the transmission electron microscope (TEM). The added benefit of higher resolution is a feature of the TEM.
We can now investigate the ultrastructure of organelles, viruses, and macromolecules because to the improvement in resolution.
Thus, the correct option is C.

A roller coaster is moving at 25 m/s at the bottom of a hill. Three seconds later it reaches the top of the hill moving at 10 m/s. What was the acceleration of the coaster?
Answer:
Acceleration = 5 m/s2
Explanation:
As, acceleration is the rate of change of velocity per unit time, we have the formula;
acceleration = change in velocity / change in time
a = 25 m/s - 10 m/s / 3 seconds
a = 15 m/s / 3 seconds
a = 5 m/s.s
a = 5 m/s2
So, the acceleration of the roller coaster is 5 m/s2
