Answer:
Two sets of chromosomes
One set of chromosomes
Haploid
Diploid
Explanation:
Diploid cell is a cell that contains two complete sets of chromosomes, each coming from both parents. e.g. a human cell, excluding sex cells, contains 46 chromosomes, each parent contributing 23 each
Haploid cells are cells containing one complete set of chromosomes i.e a single set of unpaired chromosomes. e.g gametes or sex cells that contain 23 chromosomes
Plants alternate between a life cycle in which they have one set of chromosome in their cell and two sets of chromosomes in their cell.
The gametophyte is the haploid plant form of an organism which produces the haploid reproductive gametes e.g. sperms and eggs. The gametophyte is developed by the spores, which is produced by the sporophyte. The haploid sperm fertilizes the haploid egg to form a diploid zygote, which gradually develops into the diploid sporophyte.
The sporophyte is a diploid multicellular generation found in plants and algae that produce haploid spores. These haploid spores are produced when the sporophyte organism undergoes meiotic (reduction) division. The spores then undergo mitosis or growth, without changing the number of chromosomes, to become a haploid multicellular gametophyte.
The gametophyte produces gametes and the cycle starts again. This process is referred to as ALTERNATION OF GENERATIONS.
Answer: Gamete
Explanation: <u>Gametes are an organism's reproductive cells.</u> They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Answer: These methods works by denaturing the enzymes. The first and the second method is to change the temperature and the third method is to change the pH.
Explanation:
The browning of the fruits or vegetables takes place due to the action of the enzymes. The enzymes inside the body of the organism works under specific conditions.
These conditions are temperature and pH. Change the optimum pH and temperature of the environment of enzymes could denature it.
In these case the enzymes would not work efficiently and the browning of fruits will not take place.
By cooling or boiling the fruit changes the temperature of the enzyme and in this temperature the enzymes do not work effectively.
In case of ascorbic acid the pH is acidic and enzymes do not work at lower pH.
So, by changing the pH and temperature, the enzymes do not work.
