Answer:
# Diffusion is a down hill process.(flow is from higher concentration to lower concentration)
# It does not require energy.
but,
# Active transport is a uphill process.(flow is from lower concentration to higher concentration)
# It requires energy.
Two features of diffusion that do not apply to active transport are:
Diffusion is a passive process that does not require energy input, while active transport requires the expenditure of energy in the form of ATP.Diffusion occurs down a concentration gradient, from an area of high concentration to an area of low concentration, while active transport can move ions against their concentration gradient, from an area of low concentration to an area of high concentration.What is Diffusion?Diffusion is a process by which molecules move from an area of high concentration to an area of low concentration, until they reach a state of equilibrium where there is no further net movement of molecules.
This occurs because molecules are in constant random motion, and they will naturally move from areas where they are more concentrated to areas where they are less concentrated. This process does not require energy input, and it will continue until the concentration of molecules is the same throughout the system.
Active transport, on the other hand, is a process by which molecules are moved across a membrane against their concentration gradient, from an area of low concentration to an area of high concentration.
This process requires energy in the form of ATP, which is used to pump molecules or ions against their concentration gradient. Active transport is able to move molecules or ions against their concentration gradient because it uses energy to change the shape of transport proteins in the membrane, allowing them to move molecules against their concentration gradient.
Therefore, two key features of diffusion that do not apply to active transport are that diffusion is a passive process that does not require energy input, while active transport requires energy input in the form of ATP.

Glucose and oxygen are products.
Photosynthesis
Respiration
Both
Answer:
Photosynthesis
Explanation:
In photosynthesis, carbon reduction helps make glucose, the oxygen is formed with the reduction of water in the photosystems 2 and 1.
In cellular respiration, both of these compounds would be reactants.
All human body cells contain 46 chromosomes. However, sperm cells in men and egg cells in women have only 23 chromosomes. This is due to meiosis. How does meiosis accomplish the reduction in chromosomal number?
Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.

predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein
Full Question Attached
Answer:
The substance would be less likely to enter the cell by active transport or might enter more slowly
Explanation:
The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.
If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.

Answer:
Bacteria and fungi are examples of a group of consumers called Decomposers
Explanation:
Bacteria and fungi are the organisms which are examples of a group of consumers called the decomposers. These are herbivores which are dependent upon the dead and decay material for their nutrition.
What are Consumers?
Consumers are the group of organisms which cannot synthesize their own food and hence depends upon some other organism for their nutritional requirements.
Consumers are classified further on the basis of their nutritional requirements such as herbivores, carnivores, omnivores, etc. Bacteria and fungi are the examples of decomposers which feed upon dead and decay matter for nutrition. These belong to the Kingdom Monera, Protista, and Fungi and the highest tropic level in the food chain of an ecosystem.

When Alfred Wegener first noticed that the continents fit together like puzzle pieces, this was
Answer:
- the discovery of the Pangaea Theory.
In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.
