Answer: The pathway of air in the respiratory system starts with the external organs of the nose and mouth. Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.

Which process binds together sediment to form new rock?
cementation
compaction
deposition
erosion
Answer:
It will be (cementation).
That's the correct answer.
The process that binds together sediment to form new rock is cementation. The correct option is A.
What is cementation?Cementation is the process of mineral materials precipitating in the pore spaces to harden and weld clastic sediments (those generated from preexisting rock pieces). It is the final phase of sedimentary rock formation.
Through cementation, sediments become sedimentary rock. In the spaces between the sediment particles, this action causes the precipitation of minerals.
Examples of cementing include carbonate hard ground and beach rock. Black rock is a particular kind of rock that develops along the shore and is composed of a wide variety of sediment types and sizes that have been cemented together.
Therefore, the correct option is A. cementation.

Scientists can produce many plants in the lab by cloning; culturing a few plant cells in a test tube of chemical medium. Few cells grow into a new plant. It is easy for scientists to produce many plants from just a few cells. Where would you add "cloning" to the Venn diagr
Answer:
in the epicenter
Explanation:
In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.

D) more water moving out of the cell than into the cellAccording to the complete diagram, we can see that there is a transport between cells as there is a change in appearance as the biologist added a 10% solution to the second cell.
As a result of this, we can see that through the rigid cell wall, vacuole and cytoplasm, there are mechanisms for transport as it allowed more water to move out of the cell than into the cell which caused the shrinkage.
Therefore, the correct answer is option D

Chlorophyll is a reactant of photosynthesis and a product of cellular respiration
Answer:
b. The products of photosynthesis are the reactants of cellular respiration
Explanation:
This is because they are not the same equation. They do not have the same products or reactants. Reactants are what is needed for the process to occur. Products are what it creates from the reactants. Chlorophyll is a pigment. If you want to look up the equations for photosynthesis and cellular respiration.

Limiting factors in water bio mes include
amount of salt
amount of dissolved oxygen
amount of sunlight
all of the above
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
What will happen if gametes were diploid cells?

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?
Answer:
There's not a "best" explanation unless it is a multiple choice question -
However, some prominent ways are
1) runoff from heavy rainfall
2) industrial discharge
3) storm drains
4) natural sediment transport via water flow / currents
Sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands. A large portion of the silt and contaminants are filtered out of the water as it passes through wetlands like swamps and salt marshes.
What are estuaries?A coastal body of saltwater that is partially contained, has one or more rivers or river or lake into it, and has a direct connection to the open sea is called an estuary. Estuaries are an instance of an ecotone since they are a zone of transition between river ecosystems and ocean settings.
A place in which a freshwater river or stream joins the ocean is called an estuary. In estuaries, brackish water is created when a freshwater river and the salty ocean mingle. Although not as salty as the ocean, brackish water has some saltiness. Water that descends from uplands carries contaminants including fertilisers, sediments, and more to estuaries.
Therefore, sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands.

Which of these zones of the ocean is most hospitable to life?
O A. Epipelagic
O B. Abyssopelagic
O C. Hadalpelagic
O D. Bathypelagic
Answer:
A.
Explanation:
The zones of the ocean which is most hospitable to life is the epipelagic zone. Thus, the correct option will be A.
What is the epipelagic zone?The Epipelagic zone can be referred to as the uppermost layer of the ocean. Epipelagic zone is located between the surface and the 600 feet in depth of the ocean. The Epipelagic Zone is also known as the Sunlight Zone. It is the region of the ocean which sits on the continental shelf in the oceans.
Epipelagic zone is in this thin layer which the process of photosynthesis takes place. The epipelagic zone of the ocean only represents about 2 to 3% of the entire ocean zone, beyond this zone, light is too dim for the process of photosynthesis to occur. This is the reason why, the epipelagic zone is the most hospitable zone of the life in oceans.
Therefore, the correct option will be A.

What is the difference between cytokinesis in plant and animal cells?
Answer:
The primary difference between cytokinesis in plant and animal cells is that cellular reproduction is done sexually (meiosis) in animal cells, while cellular reproduction is done asexually (mitosis) in plant cells.
To better elaborate, Sciencing.com, states, "In plant cells, cytokinesis simply consists of the cell plate forming at the equator of the old cell that will soon be two. The cell plate–the future cell wall that will separate the two cells--divides the cytoplasm in half. . . . Cytokinesis in animal cells is more complex than in plant cells. A contractile ring, underneath the original cell's membrane, begins to form and contracts, which creates the cleavage furrow. The furrow grows deeper between the two cells until they pinch off and separate from one another, resulting in two separate daughter cells."
