Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties. Quantifiable physical property is called physical quantity.
Examples:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils
melting point (intensive): the temperature at which a substance melts
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Explanation:
b. 2
c. 23
d. 46
e. There is no maximum number.
Answer:
b. 2
Explanation:
Humans have typically 23 pairs of chromosomes. Each pair is composed of a chromosome from the mother and another from the father. A specific locus in a chromosome is composed of two alleles. An allele inherited from the mother and the other allele inherited from the father.
Answer:2
Explanation:
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.

What are the different classes of protein ?
Protein is complex biomolecule made up of a multiple chain of amino acid formed by peptide bond which is a linear chain structure and it can be classified into two types such as complete and incomplete proteins.
Complete proteins contain all of the essential amino acids required for the body which include meat, fish, poultry, dairy, and soy products.
incomplete Foods where one or more essential amino acids are absent are called as incomplete proteins which include beans, grains, nuts, and vegetables.
it can be classified into five major Classes such as Enzymes, Structural Proteins, Transport Proteins, Regulatory Proteins and Hormones. where Enzyme catalyse the biochemical reactions in the body and Structural proteins provide support for cells and tissues.

Pedigree charts are used to trace the passing out of traits(characteristics) through generations.
In the given pedigree of 5 generations, the pattern of inheritance of genetic abnormality of polydactyly(extra fingers in hands and toes) is studied . The types of pattern of inheritance in traits over generations.
(a) Genotype of the parents for the trait Polydactyly in generation 1
Since each parent provide one allele of each trait to the offspring there are dominant and recessive genes on the basis of the expression of the character or trait. The genotype of the parents for thre trait of polydactyly in generation 1 is Recessive. Because both the parents do not have the abnormality and their offspring shows(expresses) the trait.
(b) In humans there are 46 chromosomes arranged as 23 sets of 2 chromosomes in a cell which is described as (2n). These somatic cells undergo Mitotic division to produce 2 identical daughter cell with 2n chromosomes and they are called diploid cells. When Meiosis takes place one cell is divide into 4 Haploid cells with 23 chromosomes each, ie, the single set of chromosomes represented by n. These Haploid cells are the gamates which transfer the genetic information from parents to offspring. The gamates are 2 types the sperm and egg cells , both are haploid and during fertilization a sperm cell fuses with eggcell to form a zygote with 2n (46) chromosomes.
