Answer:
The results, when plotted as equal pitch contours, show the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Explanation: brainlest??
Answer:
the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Therefore intensity makes a tone lower or higher in pitch.

Within a cave environment, bat waste products, called guano, are decomposed by organisms such as fungi and bacteria. These are then eaten by
creatures such as flatworms. Larger animals like salamanders eat flatworms. Which correctly represents the energy flow described?
A. Fungi - Bacteria - Salamanders - Guano
B. Bats - Guano - Flatworms - Salamanders
C. Salamanders - Fungi - Bacteria - Flatworms
D. Guano - Bacteria - Flatworms - Salamanders
Answer:
D
Explanation:
The correctly represents the energy flow described in the given case is - D. Guano - Bacteria - Flatworms - Salamanders
Energy flowEnergy flow is the movement of energy that is transferred from one trophic level to another trophic level but does not revert back. It is always unidirectional and it follows II nd law of thermodynamics.
In the given food chain, energy is transferred from waste products called guano by a bat which does not involve a bat directly, thus it starts from guano, and energy moves to bacteria and then flatworms and ultimately to the salamanders.

(3) (b) The mean concentration of red blood cells in an adult is 5.5 × 106 cells per mm3 1 mm3 = 0.000001 dm3 Calculate the mean number of red blood cells in 1 dm3 Give your answer in standard form.
Answer:
The correct answer is - 5.5*10^12 cells per dm^3
Explanation:
Given:
The mean concentration of red blood cells in an adult = 5.5 × 10^6
or = 5500 000
1 mm3 = 0.000001 dm^3
Solution:
Then, 1 dm^3 = 1000000 mm^3
(55000000 × 1000000) = 5500,000,000,000
= 5.5 × 10^12

A group of your classmates want to see if fertilizer improves plant growth. They set up the following experiment: They planted three different types of plant seeds in three different types of soil. They placed all the planted seeds in either a dark or a light environment. Each plant was given the same amount of fertilizer. In a complete sentence, explain whether or not you think this is a good scientific design. What are two things that you could suggest for them to change in order to improve their experiment?
Answer:
Since they are trying to test if fertilizer helps, no sunlight, they should give the plants the same amount of light. They should also give the plants different amounts of fertilizer.

Adapting to Life at Sea: Take a look at this article from Natural History Magazine. Explain the connection between sea snake's diet, the way in which they eliminate nitrogenous waste, and their need for freshwater. Then explain why this makes life (in at least one way) difficult for them in the ocean.
Answer:
They needs fresh water for drinking purpose.
Explanation:
The Sea snakes favorite food is fish and crustaceans. These sea snakes removes nitrogenous waste in the form of ammonia. They can live in salty water but needs fresh water for drinking purpose. This makes life difficult for sea snakes in the ocean because sea snakes needs fresh water to become hydrated and the sea water is salty which they can't drink so they depends on the rainfall for drinking purpose.
The sea snakes excrete their nitrogenous wastes via cloaca and some of it from the skin.
Sea snake
The snake excretes solid as well as liquid wastes from the cloaca but sometimes the flow of excreta gets disturbed due to change in the osmolarity between the environment and the body. The oceanic water is saline which is responsible for changing the osmolarity.This is making their survival difficult in the ocean.

When will an atom give up electrons?
When more than half of the outer energy level is filled
When the n=2 level is full
When less than half of the outer energy level is filled
When the outer energy level is full
Atoms give up electrons when less than half of the outer energy level is filled, forming positively charged ions. Noble gases with a full outer shell do not easily give up or accept electrons.
An atom will give up electrons when less than half of the outer energy level is filled. In chemistry, valence electrons are electrons in the outermost shell or energy level of an atom. Atoms tend to gain or lose electrons when the valence electron shells are not filled. When atoms lose their valence electrons, they become positively charged ions. An ion is a positively or negatively charged atom or group of atoms. For instance, sodium atoms give away one electron to form sodium ions with a positive charge because the outermost shell of sodium has only one electron, which is less than half the number needed to fill the shell entirely. When more than half of the outer energy level is filled, atoms are reluctant to give up their valence electrons, which is why noble gases do not form chemical bonds easily. When the outermost shell of an atom is full, it is stable, which is why noble gases do not give up or accept electrons quickly. Therefore, an atom will give up electrons when less than half of the outer energy level is filled.For more questions on electrons

how sclerenchyma tissues are important for plant though they are dead tissue ?
Answer:
Hey friend !!!
The cells of sclerencyma are without nucleus and protoplast....they are dead cells..
They provide mechanical support to organs of the plant body....
Hence they are important for plants....
Answer:
Sclerenchyma tissues are tissues that makes up parts of the plants that are hard. Like the nuts and covering seeds etc, These tissues have a hard thickness providing agent called lignin and lignin makes the cell wall too hard the sometimes the cell contains nothing. This cell mainly provides mechanical support to the plant
Which factor does not alter the rate of hydrolysis of maltose, a disaccharide?
A.temperature of the environment of the reaction
B.pH of the environment of the reaction
C.number of enzyme molecules present
D.size of the substrate molecule
The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present.
Enzymes are biological catalysts that promote various reactions in the body. Enzymes are specific in their action. Therefore, only an enzyme can catalyze a particular reaction. The enzymes work based on a lock and key model.
A disaccharide is composed of two mononosaccharide units. The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present.

Based on the energy flow between trophic levels in an energy pyramid how much energy would be expected to be found at the secondary consumer level in this pyramid
Answer:
100J of energy is transferred to the secondary consumers
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not usually a 100% transfer of energy. This is because the organisms at each trophic level use energy derived from food substances to carry out its activities.
Only about 10% of the energy obtained at each trophic level is transferred to the next trophic level.
This implies that only about 1000J of energy is transferred to the primary consumers and 100J of energy is transferred to the secondary consumers.
