In biology, FITNESS is described as the ability to survive and create offspring. Question 4 options:
True
False

Answers

Answer 1
Answer:

Answer:

True

Explanation:

Fitness, contrary to popular belief, is not a measure of how "strong" an individual is, but instead of their ability to pass on their genes to the next generation, or in other terms, their ability to survive and create offspring.

A friend tells you that she has been saving every 5- dollar and every 10 - dollar bill she has received for the last year . She now has 80 bills for a total of $550.00 . How many 5 - dollar bills and how many 10 - dollar bills does she have ? 1 . Write an equation . 2 . Use graphing , substitution or elimination to solve the system of equations . 3 . How many 5- dollar bills and how many 10 - dollar bills does she have ? 4 . Explain why your answer is correct . 5 . Explain why you chose the method .

Answers

Answer:

1. The equations are x+y=80 \ and \ 5x+10y=550

2. we can use elimination method to solve the problem

3. She has 50 5$ bills and 30 10 $ bills

4. The values of x and y that we found satisfies the two equations which ensures that the solution is correct.

5. Elimination method involves lesser number of steps when compared with graphical method and substitution method.

Explanation:

Number of 5$ bills=x

Number of 10$ bills=y

Total number of bills=80

x+y=80

total amount=$550

5x+10y=550

Here we have two equations and we can use elimination method to solve the set of equations

x+y=80    (Equation 1)

5x+10y=550    (Equation 2)

We have to make the coefficient of one variable in both equations same.

Let us make the coefficient of x same.

(1) * 5 => 5x+5y=400   (Equation 3)

Subtract (3)from (2)

5x+10y-(5x+5y)=550-400

5x+10y-5x-5y=150

5y=150

y=150/5=30

Substitute the value of y in equation (1)

x+y=80

x+30=80

x+30=80

x=80-30=50

x=50

y=30

Answer:

Answer is in the explanation.

Explanation:

Let's make a system of equations.

5x+10y=550

x+y=80

Now let's use elimination

-5x-5y=-400

5x+10y=550

__________

5y=150

y=30

Then subsitute 30 in for y to find x. This will leave you with x=50. You will have 50 $5 bills and 30 $10 bills. You can check by subsituting x for 50 and y for 30 in both equations to show why it is correct. Eliminating makes it easier to solve the system of equations.

Why might the risk of infectious disease be high in a community that has no water treatment facility?

Answers

Answer:

The answer is The community would consume water that is not suitable for consumption.

Explanation:

Water treatment facility is a set of structures in which water is treated so that it becomes suitable for human consumption. Without water treatment facility, people would have to consume water that has not been adequately treated, which may contain toxic wastes, trash and other contaminants that affect human health, and that, as a consequence would have a high risk of causing various diseases of an infectious nature.
Because the water is not being purified. For example people don't know why people in Lake Victoria get sick all the time!! Its because they can literally walk on the water because there is so much urine, feces, and trash. 

other than earth, is also known to have magnetic pole reversal? A:venus B:Mars C:Earths moon D: The Sun

Answers

The sun have magnetic pole reversal other than earth.

What is magnetic pole reversal?

A shift in the magnetic field of the earth to the opposite polarity is known as a magnetic polarity reversal. Throughout the course of geologic time, this has happened sporadically.

What happens during a magnetic pole reversal?

The magnetic field decreases but does not vanish entirely after a pole reversal. Though there may be some particulate radiation that reaches Earth's surface, the magnetosphere and the atmosphere continue to shield the planet from cosmic rays and charged solar particles.

So, The correct option is D.

How is the theory of evolution an example of a scientific theory?

Answers

Scientific method is an empirical method of knowledge acquisition, involving careful observation, formulating hypotheses based on such observations, testing deductions drawn from the hypotheses, and refinement or rejection of hypotheses based on the results of the tests.ext we have to know what “theory of evolution” we’re talking about. Let’s begin with the theory proposed by Charles Darwin in the Origin of Species.

I don’t know what “No assumptions here” in the question details is supposed to mean. Making hypotheses is part of the scientific method. Maybe it means that a hypothesis is assumed subject to verification, while an assumption is an axiom not subject to test. The scientific method makes testable hypotheses but never makes firm assumptions.

Darwin made a lot of observations. Then he made two hypotheses:

The observed variation among individuals can accumulate to produce all the differences we observe among species.

The effect of these variations on the ability of a living entity to survive and reproduce preserves some variations and eliminates others.

The heritability of variations was essential to the theory, but it was an observed fact, not an assumption or a hypothesis.
Because Scientific method is an empirical method of knowledge acquisition, involving careful

Only some organs contain cells true or false

Answers

False; everything in your body is made up of cells.
FALSE ,The body's functions are conducted by organs. Each organ is a recognizable structure (for example, the heart, lungs, liver, eyes, and stomach) that performs specific functions. An organ is made of several types of tissue and therefore several types of cells (see Cells). For example, the heart (seeHeart) contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.r body is made up of cells
