A function is a relation between two sets in which each input value of has exactly one value for output.
What is a function?A function is a relation between two sets of values, an input and an output value given as X and Y respectively, in which each input value of X has exactly one output value for Y.
An example of a function is y = x^2 + 1.
If x = 1
Then;
y = 1^2 + 1
y = 2
The input of a function is called the domain.
The output of a function is called the range.
Since the table provided is not clear, any of such table where an input value of X gives exactly one output value of Y is a function.

A scientist is designing an investigation to study the impact of UV radiation present in high-altitude habitats on the population of mountain yellow-legged frog. What type population is most likely to be a control group for the study? (4 points)
a
Mountain frogs in low-altitude habitats only
b
Mountain frogs in their natural high-altitude habitat
c
Mountain frogs in a lab setting exposed to UV rays from a sun lamp
d
Mountain frogs in a lab setting with no UV ray exposure
Answer:
c
Explanation:
if the scientist was to look close there skin would be tightened up on the frog it is hard to see but if you look close you could see it
Answer:
C or D I think
Explanation:
D, you could compare frogs with no UV ray exposure to the ones with UV ray exposure
C, you can do the same but reverse
Edit: Meaning of control group is "A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results."
So its more likely to be D

new cells form in the ____ as a plant grows
Answer:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

Which ponds will have a higher average oxygen concentration, ponds cooler than 20 °C or ponds hotter than 20 °C?
Answer:
20c is ponds cooler that 20 c hotter so its has more oxygen
Explanation:
Suppose you have two identical solutions of glucose, A and B. The solutions are separated by a permeable membrane that will allow the movement of both glucose and water. You want to establish a concentration gradient so that more glucose in solution B will move into solution A.
How can you manipulate your experimental setup so that the glucose will move in that direction?
Answer:
Add more water to A
Explanation:
In order to establish a concentration gradient so that more glucose in solution B would move to A, more water would be needed in A.
Adding more water to A will reduce the glucose concentration of A and create a concentration gradient which will allow some glucose molecules to move from B to A in order for equilibrium to be re-established.

the table show five of the most common chromosomal abnormalities that occur during reproduction. each abnormality cause significant alteration to the genome of the individual in which they occur. analyze the information in the table and determine the genotype of the abnormality that will result in a male having some female characteristics
a) down syndrome;xy
b)edwards syndrome;xx
c) turner syndrome;xyy
d)kilinefelter syndrome;xxy
Answer:
d)
Explanation:
The abnormality that will result in a male having some female characteristics is Klinefelter syndrome that is Option D is the correct answer. The Klinefelter syndrome, which has XXY genotype. This disease affects only the male
What are the different types of chromosomal abnormalities?Chromosomal abnormalities are of different types; some are related to autosomes, and some are related to X and Y chromosomes. The down syndrome happens due to the trisomy in the 21st chromosome, which means instead of two chromosomes, there are three chromosomes.
In Patau syndrome, the trisomy is seen in the 13th pair of homologous chromosomes, and as a result, instead of two chromosomes, three are present. Klinefelter syndrome is associated with males who have an extra X chromosome. Infertility is observed as a result of this male display of female characteristics, such as behavioral changes. Turner syndrome is associated with females who have lost one X chromosome.
As a result, the correct answer is option D, which is Klinefelter syndrome, which is XXY.

The cell cycle has a direct relationship with the human life cycle.
Impact of cell on human life cycleHuman life cycle is directly related to the cell cycle of the cells that make up our bodies because our whole body is made up of trillions of cells. Cell is the structural and functional unit of an organism. Cells combine together make tissues.
Tissues join together making organ. Different organs combine together forming organ system and different organ system combine together forming human body so we can conclude that cell cycle has a direct relationship with the human life cycle.

A man suffers a penetrating wound through the anterior axillary fold, with resulting damage to one of the main terminal branches of the brachial plexus. Among the effects is a significant weakening of flexion of the elbow. One or more other effects to be expected is (are):______.
A. Loss of cutaneous sensation on the tips of several fingers.
B. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
C. Only weakening of flexion at the shoulder.
D. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the arm.
Answer:
The correct answer is option b. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
Explanation:
Brachii and brachialis are the two muscles that are innervated by the Musculocutaneous nerve. These muscles help in the production of the flexion at the elbow, and it is known that the musculocutaneous nerve is damaged due to the penetration through the anterior axillary fold.
Other than these muscles there would be an effect on the nerve that provides sensory signals or information to the anterolateral surface of the forearm, known as the lateral antebrachial cutaneous nerve.
Thus, the correct answer is: option B.
