PLSSSSS HELPP!! Population biologists are concerned about invasive species such as the zebra mussel found in North American water ways because

A.The introduced species compete for resources more effectively than native species


B.These introduced species will require more land to be protected


C.Introduced species often become endangered when they are placed in a new habitat


D.Predators of the zebra mussels will decrease after these organisms are introduced into the habitat

Answers

Answer 1

Answer: A.The introduced species compete for resources more effectively than native species.

Explanation:

An introduced species is also called the exotic species and this is an organism which is not a native organism or specie and therefore isn't native to the place but rather it's being transported to the place through the activities of human being.

When the introduced species are introduced to a particular area, they compete with the natives for the available resources and often do this more effectively than the other native species.

Therefore, the correct option is A.

A bank uses a computer program during the night to tell if the alarm should be rung. Sensors in the bank set the following Boolean variables:
vaultClosed: set to true if the bank vault is closed; otherwise false

heardNoise: set to true if a microphone heard noise; otherwise false

sawMovement: set to true if a camera saw movement in the bank; otherwise false

The automatic alarm should notify the police if there is noise and movement in the bank, or if the bank vault is open.
Which of the following boolean expressions can be used in a selection statement to ring the alarm?
A. NOT vaultClosed OR (heardNoise AND sawMovement)
B. heardNoise AND vaultClosed

Compare an electric circuit to a river flowing with water. Which of the following could appropriately be considered a source?


a spring

a place where two rivers join

an ocean

an island

Answers

Answer:

a spring.

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.

This electrical network which is usually a closed loop comprises of a device that provides the energy (voltage) to drive electrons or electric current; the device is referred to as a source such as a generator or battery.

Springs are points from which water naturally seeps from the ground. A spring is the original point or most common type of source from which a river flows or begin its journey.

This ultimately implies that, a spring serves as a source to a river flowing with water while a battery or generator serves as a source to an electric circuit with current flowing through it.

Hence, if we compare an electric circuit to a river flowing with water, a spring is considered to be a most likely source to the river.

Consider the following code segment.
int a = 3 + 2*3;
int b = 4 + 372;
int c = 7 % 4 + 3;
double d = a + b + c;
I
What is the value of d after the code segment is executed?

Answers

Answer:

20.0

Explanation:

3+2*6 = 9

4 + 3/2 = 5.5 but, since b is an int value, it will round down to a 5

7%4+3 = 3 +3 = 6. the % symbol will give the remainder of the quotient

9 + 5 + 6 = 20. It becomes 20.0 because d is a double value.

The value of d after the code segment is executed is 391.0

How to determine the value of d?

To do this, we evaluate the code statements one after the other.

So, we have:

int a = 3 + 2*3;

This gives a = 9

int b = 4 + 372;

This gives b = 376

int c = 7 % 4 + 3;

This gives c = 6

For double d = a + b + c;

Substitute a = 9, b = 376 and c = 6 in d = a + b + c;

So, we have:

d = 9 + 376 + 6

Evaluate the sum

d = 391.0

Hence, the value of d after the code segment is executed is 391.0

A computer database uses a binary sequence of 10 bits to represent unique user IDs. To increase the number of unique IDs that the database is able to represent, the database administrator increases the number of bits in a user ID to 11 bits. How many times more unique user IDs can be represented with the new system?

Answers

Answer:

2 times more unique IDs

Explanation:

The number of bits used to represent unique IDs in the computer system = 10 bits

The number of bits to which the database is upgraded to = 11 bits

The number of unique IDs represented by a 10 bits binary sequence, n = 10¹⁰ = 1024

The number of unique IDs represented by a 10 bits binary sequence, n = 10¹¹ = 2048

Therefore, the number of times more unique IDs that can be represented with the new system of 11 bits = 2048/1024 = 2 times more unique IDs
