Answer:
B. Active Transport
Explanation:
The concentration gradient is from high to low. The molecules are moving from low to high which is against the concentration gradient. Also, the ATP symbol is shown pointing, and ATP is energy.
The description that best identifies the type of cellular transport being depicted in the image would be that of active transport because energy is being used to move molecules against a concentration gradient.
There are basically 2 types of cellular transports:
PassiveActivePassive cellular transports are those that do not require energy in any form. They include osmosis, the movement of water molecules from the region of high to low water potential via a semi-permeable membrane, and simple/facilitated diffusion, the movement of molecules from regions of high concentration to regions of low concentration.
Active transports are those movements of materials in and out of the cell that requires the expedition of energy in the form of ATP. It is usually the movement of materials against their concentration gradients. Examples include vesicle transport, ion pumps, etc.
In the illustration, the direction of movement of the molecules (by the arrow) indicates that it is against the concentration gradient. Also, the burning of ATP gives further credence that is an active system of cellular transportation.

Which statement best supports the theory that eukaryotic cells evolved
through endosymbiosis?
A. Eukaryotic cells can eat prokaryotic cells by engulfing them with
cell membranes.
B. All prokaryotic cells are covered by a stiff cell wall that protects
them.
C. Their chloroplasts contain DNA that is similar to that of
prokaryotes.
D. Chains of amino acids form inside tiny bubbles filled with organic
molecules.
Answer:
Their chloroplasts contain DNA that is similar to that of
prokaryotes
Explanation:
This is based on the theory that the membrane bound organelles of chloroplast and mitochondria which are peculiar to Eukaryotas evolved from bacteria by endosymbiosis. Thus bacteria contain the DNA of these organism Evidently, these organism (Eukaryotas) must have cohabited with bacteriA some time ago
The outside of a bacterial cell is protected by a structure called a ??
Which of these is a form of nonrenewable energy?
O A. Fossil fuel energy
O B. Solar energy
C. Wind energy
O D. Hydroelectric energy
Answer:
Fossil fuel energy
Explanation:
This is because oil from fossils take a millions of years to form and people won't be able to wait millions of years
Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.
What is Non-renewable energy?A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.
There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.
Therefore, the correct option will be A.
