describe one way an invasive species, such as the zebra mussel, can decrease the carrying capacity for a native species in an ecosystem.
The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.

Hydrogen selenide (H2Se) reacts with water according to the following equation. H2Se H2O → SeH– H3O In three to five sentences, identify the acid, base, conjugate acid, and conjugate base in this reaction. Use patterns in the periodic table to explain why the substances you identified acted as the acid and the base in this reaction.
Taking into account the Brønsted-Lowry acid-base theory:
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.
The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.
According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.
So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.
In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:
acid + base ⇄ conjugate base + conjugate acid
In this case, you know:
H₂Se + H₂O → SeH⁻ + H₃O⁺
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.
So, H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.

A community pool that is shaped like a regular pentagon needs a new cover for the winter months. The radius of the pool is 20.10 ft. The pool is 23.62 ft on each side. To the nearest square foot, what is the area of the pool that needs to be covered? 192 ft2 960 ft2 1,921 ft2 3,842 ft2
Answer:
B. 960 ft^2
Explanation:
edge says trust me
Based on the calculations, the area of this pentagonal pool that needs to be covered is equal to: B. 960 ft².
Given the following data:
Radius of pool = 20.10 ft.
Side length of pool = 23.62 ft.
How to calculate the area of the pool?Mathematically, the area of a regular pentagon can be calculated by using this formula:
A = ¹/₄√(5(5 + 2√5)a²)
Where:
a is side length.
Substituting the parameters into the formula, we have:
A = ¹/₄√(5(5 + 2√5)23.62²)
A = ¹/₄√(5(5 + 2√5)557.9044)
A = 959.86 ≈ 960 ft².

a pedometer treats walking 1 step as walking 2.5 feet. define a function named feet_to_steps that takes a float as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. then, write a main program that reads the number of feet walked as an input, calls function feet_to_steps() with the input as an argument, and outputs the number of steps.
The required program written in python 3 defines a function which converts the number of feets walked into steps and returns an integer value for the number of steps. The program goes thus :
def feet_to_steps(feet):
#initialize a function called feet_to_steps
num_steps = feet / 2.5
#divide the number of feets by 2.5 and assign the number of steps to the variable num_steps
return round(num_steps)
#return the rounded integer value of num_steps
your_feet = eval(input('Enter feets number of feets walked : '))
#prompts the user to input a float value for the number of feets
#A sample run of the program is given below and attached.

"Elgin Marbles" has the theme "decay is inevitable," while "Ozymandias" has the theme "fame survives death."
The two passages have the theme "time erases everything," as shown in the first answer option.
We can arrive at this answer because:
The passage from the poem "Ozymandias," shows how all the glory, wealth, and magnificence of a great leader fades over time.In this poem, we can see that someone seen as the king of kings, can have all his power terminated and buried in the sand.In "On Seeing the Elgin Marbles," we can see how memorable moments pass and become memories of "the old days," even though it seems like it will last forever.In this case, we can see that the two poems reinforce the idea that everything is fleeting, and that time brings the end of all things.

Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
