How do toothed whales produce general communication sounds?
Answer:Toothed whales do not make the long, low-frequency sounds known as the whale song. Instead they produce rapid bursts of high-frequency clicks and whistles. Single clicks are generally used for echolocation whereas collections of clicks and whistles are used for communication.

28. Eubacteria can be distinguished from archaebacteria by
a.The presence of a true nucleus
b. Being multicellular
Difference in the makeup of cell wall
d. The presence of organelles
Answer: D
Explanation:
i am sorry if this is wrong
Vacuoles are cellular organelles that are found in all plant and fungal cells. In plant cells, vacuoles tend to store large amounts of water, so they can push outward on cell walls and help keep plants upright. In fungal cells, vacuoles often store materials that are toxic to the cell.
According to the above information, how do vacuoles help fungal cells maintain homeostasis?
A.
by storing large quantities of water
B.
by allowing the cells to get rid of waste
C.
by producing more cellular organelles
D.
by helping the cells extract energy from food
Answer:
D. by helping the cells extract energy from food
Explanation:
Fungi are decomposers so they normally need some sort of food to grow. To get the energy to grow, they extract it from the food. Fungi will get their energy from dead animals, dead plants, etc.

11. Mycorrhizal Fungi and Plants: The mycorrhizal fungus grows into the roots of some plants and gets nutrients from the plant. The fungus helps the plant absorb inorganic nitrogen and phosphorus from the soil. Some fungi also secrete antibiotics, which can help protect the plant from parasitic fungi and bacteria. _______________________________

Explanation:
How do toothed whales produce echolocating sounds?
Answer:
As the lips vibrate, the sound is transmitted via the whale's 'melon' – fatty tissue that makes up its forehead. This tissue has the same acoustic properties as water. ... Toothed whales can direct sound by bouncing it off air sacs in their nose and possibly by using face muscles to alter the shape of the melon.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.

Explanation:
3. Compare and contrast the movement produced by each of the three types
Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
Therefore, the statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.

The law of conservation of energy states that energy cannon be created or destroyed.
O True
O False
Answer:
false
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

Answer:The target cells of neurons include other nerve cells in the brain, spinal cord, and autonomic ganglia, and the cells of muscles and glands throughout the body.
Explanation:please give braineest
Answer:
A nerve is formed by a bundle of many neurons. Neurons develop from the neural tube of the early embryo and in many animals continue development until sometime after birth. The development of motor neurons that have elongated axons is best understood. These cells are derived from tissue on the ventral side of the neural tube.

What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.
The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.
Explanation to the difference in the cellular vacuole size:When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.

Answer:
The correct answer is - characteristics of all vertebrate animals.
Explanation:
Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.
The only characteristic among these that present in both is that they both immune systems found in all vertebrates.
