Is this a good scientific question? “Is the lifespan of snowshoe hares, which are white in the winter and brown in the summer, affected by levels of winter snowfall?” A) Yes, because the question is specific. B) No, because the question cannot be tested in a laboratory. C) Yes, because the question has already been answered. D) No, because the question does not lead to a hypothesis.

Answers

Answer 1

Answer:

The answer is: A) Yes, because the question is specific.

The scientific method is a process for experimentation that is used to explore observations (in this example color of snowshoe hares).

Steps of the scientific method:

1) ask a question about something that is observed.

2) do background research.

3) construct a hypothesis, an attempt to answer questions with an explanation that can be tested.

4) test of hypothesis.

5) analyze collected data and draw a conclusion.

The two main variables in an experiment are the independent and dependent variable.

Dependent variable is the variable being tested and measured in a scientific experiment, in this example lifespan of snowshoe hares.

Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.

Answer 2

Answer: A) Yes, because the question is specific.

What fraction of a Sr-90 sample remains unchanged after 87.3 years

Answers

The answer is 1/8.

Half-life is the time required for the amount of a sample to half its value.
To calculate this, we will use the following formulas:
1. $(1/2)^(n) = x$ ,
where:
n - a number of half-lives
x - a remained fraction of a sample

2. $t_(1/2) = (t)/(n)$
where:
$t_(1/2)$ - half-life
t - total time elapsed
n - a number of half-lives

The half-life of Sr-90 is 28.8 years.
So, we know:
t = 87.3 years
$t_(1/2)$ = 28.8 years

We need:
n = ?
x = ?

We could first use the second equation, to calculate n:
If:
$t_(1/2) = (t)/(n)$ ,
Then:
$n = (t)/( t_(1/2) )$
⇒ $n = (87.3 years)/(28.8 years)$
⇒ $n=3.03$
⇒ n ≈ 3

Now we can use the first equation to calculate the remained amount of the sample.
$(1/2)^(n) = x$
⇒ $x=(1/2)^3$
⇒ $x= (1)/(8)$

The elements of ________ are: 1) the felonious taking of personal property, 2) from the person or immediate presence of another, 3) against the will of the victim, and 4) accomplished by means of force or by putting the victim in fear.

Answers

Answer:

robbery

Explanation:

The elements of robbery are 1) the felonious taking of personal property, 2) from the person or immediate presence of another, 3) against the will of the victim, and 4) accomplished by means of force or by putting the victim in fear.

Action of taking property by unlawfully from a person or place by force or threat of force is called robbery and all above condition satisfies the term robbery hence robbery is correct match.

Coastal flooding occurs when_

A. Rocks or debris block rivers causing them to overflow

B. Severe weather occurs causing large waves to hit the coast

C. Huge amounts of snow and ice melt due to sudden temperature variations

D. Colossal amounts of rain fall in a short period of time

Answers

Coastal flooding occurs when normally dry, low-lying land is flooded by seawater.[1] The extent of coastal flooding is a function of the elevation inland flood waters penetrate which is controlled by the topography of the coastal land exposed to flooding.The seawater can flood the land via from several different paths:

After doing multiple titrations, your NaOH solution is determined to have a mean concentration value of 0.100 M. Given you are to assume your unknown acid is 75.0% KHP, how many grams of your unknown will you need to use 15.00 mL of your 0.100 M standardized NaOH

Answers

Answer: The mass of unknown acid needed is 0.230 grams

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

Molarity of NaOH solution = 0.100 M

Volume of solution = 15.00 mL = 0.015 L (Conversion factor: 1 L = 1000 mL)

Putting values in above equation, we get:

$0.100M=\frac{\text{Moles of NaOH}}{0.015L}\n\n\text{Moles of NaOH}=(0.100mol/L* 0.015L)=0.0015mol$

The chemical reaction for the reaction of KHP and NaOH follows

$KHC_8H_4O_4(aq.)+NaOH\rightarrow KNaC_8H_4O_4(aq.)+H_2O(l)$

By Stoichiometry of the reaction:

1 mole of NaOH reacts with 1 mole of KHP.

So, 0.0015 moles of NaOH will react with = $(1)/(1)* 0.0015=0.0015mol$ of KHP

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Moles of KHP = 0.0015 moles

Molar mass of KHP = 204.22 g/mol

Putting values in above equation, we get:

$0.0015mol=\frac{\text{Mass of KHP}}{204.22g/mol}\n\n\text{Mass of KHP}=(0.0015mol* 204.22g/mol)=0.306g$

We are given:

Mass of unknown acid = 75 % of Mass of KHP

So, mass of unknown acid = $(75)/(100)* 0.306=0.230g$

Hence, the mass of unknown acid needed is 0.230 grams

Carrying capacity is _____.the ratio of predators to prey
the number of populations in a specific area
the number of organisms in a population
the number of organisms an ecosystem can support

Answers

Carrying capacity is the number of organisms an ecosystem can support. It is the maximum size of a population that can survive in the ecosystem. If the animals reach the carrying capacity, the population may crash. As the consequence, the number of animals will decrease due to predators or diseases.

The answer is: number of organisms an ecosystem can support.
