C.A database of test scores for a group of students
Explanation:
Quantitative data measures things and records values as numerical data. Only option C that measures test scores records values as numerical data.
Rest are qualitative.
Answer:
Option A, Acquisition
Explanation:
The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.
For example – If a bird is trained to pick a key whenever there is a sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
Thus, option A is correct.
Answer:
Well a living thing is defined as in a scientific term, the ability to reproduce. Living things like humans, animal and even plants are considered living because we can reproduce, even plants by making new seeds in the plant growth process. Non living things are things that won’t be able to reproduce, like for example a rock can t reproduce since it’s not living and it just “lacks the abitlity to”.
If a cell has 18 chromosomes the daughter cells would have 18 chromosomes after mitosis.
c. 18
<u>Explanation:</u>
Mitosis is the DNA replication process which maintains the number of chromosomes in daughter cells equal to number of chromosomes in parent cell. In the process the parent cell divides into two daughter cells having the same chromosome number as that of parent cell.
Meiosis is a process different from that of mitosis where each parent cell divides into four daughter cells having half the number of chromosomes present in the parent cell.
Since sex cells have to be haploid in organisms like human beings, it is the process of meiosis that takes place in reproductive cells.
Answer:
It will shrink because it was placed in a hyper tonic solution
Explanation: Hyper tonic = More solute (sugar)
Hypo tonic = more liquid (water)
When a cell is placed in a solution it will essentially try to balance out so in this case water goes out the cell and solute goes, in shrinking the cell.
