When do changes and
Interactions occur In The
Great Oxygenation event?
Answer:
Stage 1 (3.85–2.45 Ga): Practically no O2 in the atmosphere. ... Stage 2 (2.45–1.85 Ga): O2 produced, rising to values of 0.02 and 0.04 atm, but absorbed in oceans and seabed rock. Stage 3 (1.85–0.85 Ga): O2 starts to gas out of the oceans, but is absorbed by land surfaces. No significant change in oxygen level.

Which of the following is not a type of biological contamination?
A)bacteria
B)protozoa
C)viruses
D)herbicides
Herbicides are not a type of biological contamination since they are toxic substances that are not living things.
Biological contamination is the contamination by living microorganisms that are toxic. Herbicides are not the type of biological contamination. Thus, option D is correct.
What are biological contaminations?
The contamination of the food, water, air, or soil due to harmful living organisms is called biological contamination. These microbes cause diseases and illnesses in the other species.
Viruses, bacteria, and protozoans are the biological contaminants that result in diseases and pollution. On the other hand, herbicides are chemical substances that are used to kill the pests infesting the crops.
Therefore, herbicides are not biological contaminants.

What process is being used by the cell to move the molecules
The process that is being used by the cell to move the molecules is known as diffusion.
Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane. It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.
In conclusion, the correct option is Diffusion.

describe one piece of evidence represented by the contour line on the map that indicates the north side of chimney bluffs is steep?
Incomplete question. Attached is the image of the map below.
Explanation:
From the map, we could notice the contour lines around the Chimney Bluff areas are closely packed together. In other words, the spacing between the contour lines is narrower than those found in other locations.
This assertion is accurate because it is a standard practice in many maps to indicate the steepness of an area by having the contour lines in close proximity.
(HELP WANTED AUTOMATIC BRAINLY) Which statement describes how the muscular and skeletal systems cause parts of the body to move?
A. When a muscle relaxes, it causes a bone to shorten.
B. When a bone shortens, it lengthens the muscle attached to it.
C. When a bone bends, it pushes a muscle in the opposite direction.
D. When a muscle contracts, it pulls a bone in one direction.
Answer:
C.
Explanation: Because when a bone does bend the muscles pull back so the bone doesnt dislocate.
The statement describes how the muscular and skeletal systems cause parts of the body to move is when a muscle contracts, it pulls a bone in one direction.
What is skeletal system?The skeletal system is the in charge of all the bones and skeleton of the body. The skeletal system provides structure and strength to the body and protects the soft tissues.
The muscular system and the skeletal system work together as the muscles and bones are connected with each other.

Answer:
A microbe is a small living thing too tiny to be seen by the naked eye and includes bacteria, fungi and viruses. Among their destructive actions is causing diseases in human beings and their livestock or plants, destruction of food by causing decomposition which might lead to hunger and other related calamities. Despite this destructive consequences, microbes are also known to have advantageous actions like helping in sewerage treatment, microbes found in the gastro-intestinal tract help in maintaining a good environment for digestion to take place. Microbes also help in ecological balance by causing decomposition of dead matter hence conserve the environment.

Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.
Answer:
The correct answer would be - low flower density and low deep flower proportion
Explanation:
To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.
To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.
Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.
This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.
How do flower visitors diverse the traits?It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.
The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.
In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.
Therefore, the correct answer is low flower density and low deep flower proportion.
