Scientific data refers to the information collected by using the scientific method. These data can be obtained from experimental and/or observational procedures.
- There are two types of data: qualitative data and quantitative data.
- Qualitative Data is a set of data describing the findings of an experiment (Option B).
- On the other hand, quantitative data refers to the set of measurements/numbers collected in an experimental or observational procedure.

Answer:
Ss × ss
Explanation:
This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).
According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.
Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).
Answer:
Contraction.
Explanation:
Muscle tissues are defined as they are elastic and extensible in nature. In other words it's also defined as they are able to stretched and returned to its original size and shapes. A unique feature of muscle tissue is they are able of contractile in nature. With the help of this contraction they are able to sliding myosin and actin filaments which are present in muscles tissues.
Basically muscle tissues are three types:
1) Skeletal muscle: They are strong and rapid in contraction.
2) Cardiac muscle: They are strong in contraction.
3) Smooth muscle tissues: They are slow and weak in contraction.
Answer:
The given statement is false.
Explanation:
The mammals can be differentiated into three main groups on the basis of the development of their babies. These three groups are marsupials, monotremes, and placental mammals, which is the largest group. The monotremes refer to the mammals, which lay eggs. The marsupials refer to the mammals, which give birth to young ones that are not developed completely. While in a placental mammal, the development takes place within the body of a mother until and unless its systems of the body start to work on their own.
