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:
The percentage of people in Botswana that have HIV is 24. 83 percent .
Explanation:
Lesotho and Swaziland are the only country who is higher than Botswana in terms of terms of HIV prevalence rate in the world between adults aged from 15 to 49 years .
This condition has led to a major depletion in Botswana's workforce, because a good number of productive adults (18 to 50) developed AIDS and are unable to work .
Explanation:
Acceleration of a body is the change in the velocity of the body with the passage of time. A body with a constant velocity is not accelerating.
Acceleration =
The SI unit of acceleration is m/s²
Velocity is the rate of change of displacement with time:
Velocity =
The SI unit of velocity is m/s
Distance is how far two points are from one another. The SI unit is in meters
