The Texas Hill Country ecosystem supports a variety of organisms. Animals such as owls, coyote, snakes and hawks compete for small animals for food. What might happen if the population of these predators became too large? The predators would share the prey population equally among all of the predator species. The predators would begin to eat plants rather than their usual prey. The predators would have more offspring of great size. The predators would consume the prey population faster than it could be replaced.
Answers
Answer:
The predators would consume the prey population faster than it could be replaced.
Explanation:
According to Oxford dictionary; an ecosystem is "a biological community of interacting organisms and their physical environment."
An ecosystem is a self supporting unit that is composed of living and non living parts. The ecosystem should be self sustaining.
In the particular case mentioned in this question, when the predator population becomes so large, they will steadily diminish the prey population faster it can be replaced thereby distorting the balance of the ecosystem.

When the wave passes through the medium
Answers
Answer: hewo, there! your answer is Below
A single disturbance passing through a medium is called a pulse.
Explanation:
When the disturbances are repeated in a periodic manner, the pulses generate a continuous wave. Longitudinal waves (also called compression waves – a slinky pushed and pulled) – moves parallel (same direction) to the wave motion.
Hope this helps !!
Have a amazing day !!!!
Answer:
When the energy of a wave passes through the medium, particles of the medium move. The more energy the wave has, the farther the particles of the medium move. The distance the particles move is measured by the wave's amplitude.

Oxidation state of Ruthenium?
Answers
Answer:
0 to +8, and −2
Explanation:
Answer:
In addition to carbonyl and organometallic compounds in the low oxidation states −2, 0, and +1, ruthenium forms compounds in every oxidation state from +2 to +8. Very volatile ruthenium tetroxide, RuO4, used in separating ruthenium from other heavy metals, contains the element in the +8 oxidation state.
Valence: 1, 2, 3, 4, 5, 6, 7, 8
Melting point: 2,250° C (4,082° F)
and the most stable oxidation state of ruthenium is +8

Where does the energy for almost all ecosystems come from
Answers
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
What does q = 0.75 g x 0.897 J/g•°C x 22°C equal?
Answers
Answer:
14.8005 Joules
Explanation:
This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat (Joules)
m = mass of substance (g)
c = specific heat of substance (J/g°C)
∆T = change in temperature of substance i.e. final temperature - initial temperature (°C).
According to this question, the following expression is given:
q = 0.75 g x 0.897 J/g•°C x 22°C
To calculate this further, this will equal to: 14.8005
This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.

1.8 mol HCl and 3.3 mol NaOH react accord- ing to the equation HCl + NaOH −→ NaCl + H2O . Calculate the amount in moles of NaCl formed. Answer in units of mol.
Answers
Answer:
1.8 moles of NaCl must be produced.
Explanation:
Based on the reaction:
HCl + NaOH → NaCl + H2O
1 mol of HCl reacts with 1 mol of NaOH to produce 1mol of NaCl
To solve this question we must find, as first, the limiting reactant:
1.8 moles of HCl will need 1.8 moles of NaOH for a complete reaction (Ratio of reaction 1:1). As there are 3.3 moles of NaOH,
HCl is limiting reactant
When the 1.8 moles of HCl react completely,
1.8 moles of NaCl must be produced because 1 mole of HCl produce 1 mole of NaCl

Answers
Answer:
4. D
Explanation:
Matter can exist in three states namely: solid, gas and liquid. These three states are individually unique because they possess different properties or characteristics. Matter consists of particles, which behave differently in the different states.
Particles of a liquid e.g water, ethanol etc. will move freely about in the container it is placed but in close contact with one another. This means that the particles move freely while still attached to one another. This accounts for the reason liquids are said to FLOW.

Answers
Elements are more reactive as you go down the periodic table because ionization energy decreases down a group which means they can lose electrons more easily, making them more reactive.
The modern periodic table is arranged by atomic number rather than atomic mass, and many discoveries of new elements have been made that make a more complete table.
The vertical columns and horizontal rows in Mendeleev’s table are called groups and periods respectively. There are seven periods and eight groups. Elements with the same properties are in the same group and all elements were ordered by atomic mass.
Three drawbacks of Mendeleev’s table are: it’s arranged by atomic mass rather than atomic number. Isotopes violate Mendeleev’s periodic law. Mendeleev could not figure out where to place hydrogen.
Modern periodic table is arranged by atomic number, it has 7 periods and 18 groups, and is divided into 4 blocks (s-, p-, d-, and f-)
