what is the range for the following set of measurements? 27c, 12c, 31c, 19c, 23c, 11c, 17c
A) 0c to 100c
B)11c to 31c
C)1c
D)27c to 17c
Answer: B) 11c to 31c
Explanation:
We know that the range of any data gives us a interval which contains all the data and provides an indication of statistical dispersion from minimum value to the maximum value.
The given set of measurements : - 27c, 12c, 31c, 19c, 23c, 11c, 17c
Here the highest measurement :- 31c
The least measurement :- 11c
Then , the range of the given set will be :-
11c to 31c
Hence, the range for the given set of measurements is 11c to 31c .

a chemist is studying the effects of minerals on plant growth. she knows that phosphorus stimulates plant growth. She decides to test the effects of various phosphorus concentrations on plants every 5 days over a 20 day period. What is the independent variable in this experiment
a. amount of plant growth
b. phosphorus concentration
c. time of experiment
d. types of plants
Answer: Option B
Explanation:
A chemist is performing an experiment in which he is testing the effect of various phosphorus concentration on the growth of plants.
She decides to change the concentration of phosphorus on every 5th day over a total growth period of 20 days.
The growth of plants will change according to change in concentration of phosphorus. So, the concentration of phosphorus is independent variable.
Hence, the correct answer is option B
if a cell is isotonic in an 80% sucrose solution, how will the movement of water across the cell membrane affect the size of a cell if it is moved from an 80% sucrose solution to a 40% sucrose solution
The answer is; The cell will increase in size
When the cell is moved is the 40% sucrose solution, the solution will be hypotonic to the cytoplasm of the cell. Therefore, through osmosis, water will move from the sucrose solution to the inside of the cell. In osmosis, water moves from a hypotonic solution to a hypertonic solution through a semi-permeable membrane. If the cell is an animal cell, it may lyse because it has no cell wall to give it structural support.

What is a chain of amino acids called?
A chain of amino acids is known as a polypeptide.
• The fundamental unit of a protein is known as an amino acid. It is a monomer, which joins together to give rise to a protein.
• The amino acids are joined together by a bond known as peptide bonds.
• The joining of amino acids is a dehydration synthesis as in the process a molecule of water is eliminated.
• The two amino acids joined together is known as a dipeptide, and a long chain of amino acids is known as a polypeptide.
Thus, the chain of amino acids is known as a polypeptide.

Not breastfeeding baby what happens later
Final answer:
Not breastfeeding a baby means missing out on the vital nutrients, immunoglobulins, and other health benefits provided by breast milk. Sudden cessation of breastfeeding can cause physical effects in the mother, like breast engorgement and leakage, due to a disrupted supply-demand relationship. Without resumption, milk production will usually cease within about a week.
Explanation:
When a baby is not breastfed, they do not receive the benefits provided by breast milk. Suckling stimulates the production of prolactin which leads to milk production in the mammary glands. Oxytocin is released as well, which aids in milk let-down. This process ensures that the baby receives a balanced supply of nutrients tailored to its development phase, including colostrum, which is rich in immunoglobulins necessary for the infant's immune system. Additionally, breast milk contains components that help the infant's digestive system expel meconium and clear bilirubin. If a mother stops breastfeeding suddenly, prolactin and oxytocin levels can decrease, leading to breast engorgement and leakage, mirroring the experiences in the initial weeks following birth. The engorgement occurs because the supply-demand relationship has been disrupted. Although a lactating person can produce milk for years, if breastfeeding is not resumed within approximately one week, the remaining milk will be reabsorbed, and in most cases, no more will be produced.
How have the Earth systems and life co-evolved over time?
Through evolution. The mechanism by which organism adapt and be able to survive in an environment however limited is because of evolution. Primitive life is different from the current ones because the early Earth was different from the ones that exists today. Further, as life thrived, Earth was able to supply the necessary materials for life to survive and continuous be complex as it is today.

an atom has an atomic number of 17, a mass of 37 amu, and a charge of -1. How many protons does this atom have? How many neutrons does this atom have? How many electrons does this atom have?
Answer:
In conclusion, we have:
17 protons
18 electrons
20 neutrons
Explanation:
Hello!
Let's solve this!
The atomic number indicates the number of protons that is equal to the number of electrons.
In this case, the number of protons is equal to 17.
The number of electrons is equal to 17.
To calculate the number of neutrons, we subtract the mass:
37-17 = 20.
Since the mass is equal to the number of neutrons plus that of protons.
In this case, the number of neutrons is 20.
As it has a charge -1, we add one more electron.
In conclusion, we have:
17 protons
18 electrons
20 neutrons

Snakes shed their outermost layer of skin regularly. Which characteristic of life is this action an example of?
A)excretion
B)growth
C)homeostasis
D)nutrition
E)reproduction
Answer:
the correct awnser is (A)
Explanation:
It seems to either be homeostasis so the snake may regulate its state of being like how a person will take off their coat when it gets too warm or growth where the snake sheds its skin to prepare for growth. From what I can tell, the answer can't be excretion, reproduction, or nutrition. As the skin, gave no initial nutritional value so that eliminates excretion and nutrition. The snake isn't giving birth to other snakes during this process so that eliminates Reproduction.

Answer:
The correct order for the process of water eroding soil is A.
1. Sheet erosion: Water will remove a thin layer of soil from the soil surface.
2. Rill erosion: Running water forms small channels in the soil.
3. Gully erosion: Running water moving on the rills concentrate to form larger channels.
Which term is associated with asexual rather than sexual reproduction?
A) zygote
B) conjugation
C) binary fission
D) alternation of generations
Answer: C. Binary fission
There are two modes of reproduction used by the living organisms to reproduce offspring. The asexual mode of reproduction is a process in which the organism does not require the gamete formation, and does not require a mate for copulation, only a single parent is involved in this process. The offspring produce are genetically identical to their parent. But sexual reproduction gamete formation is necessary, and a mate is required for copulation. The offspring are not genetically identical to their parents.
Binary fission is a term that is associated with asexual rather than sexual reproduction. Binary fission is a type of asexual reproduction, in this a fully mature parent cell divides into two daughter cells. In this process segregation of the genetic material and it's replication takes place simultaneously. The genetic material is equally distributed to both of the daughter cells. Binary fission can be observed in some prokaryotes such as bacteria. It is also seen in single celled eukaryotes such as Amoeba and Paramecium.
During digestion, water is both added and removed. Which area of the digestive system removes water?
Answer:
Large intestine
Explanation:
Large intestine is the part of the digestive system that consists of cecum, the colon and the rectum. The undigested food enter from small intestine into large intestine. Function of large intestine is to absorb water, salts and vitamins from the undigested food. The undigested and unabsorbed substances form faeces and is stored in rectum till defaecation.
Answer:
Large Intestine
Explanation:
Water from the undigested food is removed by the large intestine. All the nutrients have been absorbed from the food before it reaches large intestine.
Large intestine removes water and make stool consistent enough so that it is easily removed.
There are three main parts of large intestine
a) Cecum - cecum has no major role in food digestion. It passes the food to the colon
b) Colon - It has three sub parts
i. the ascending colon - Bacteria in colon digest the remaining food
ii. the transverse colon - It absorbs fluid and salts
iii. the descending colon - hold the waste
c) rectum
