I) Independent assortment.
II) Nucleosomes, DNA, chromatin, chromosomes.
III) 3.
EXPLANATION:➻ Recombination scrambles pieces of maternal and paternal genes, which ensures that genes assort independently from one another.
➻ We know that Chromatin is a complex of DNA and proteins that forms chromosomes. Chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA.
➻ Triploids with three different alleles can easily be detected because they have a unique phenotype.
The process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene.
In independent assortment, different gene variants or 'alleles' are independently and randomly assorted into daughter cells, which allows genetic recombination.
In eukaryotic organisms, DNA is associated with histone proteins in order to form nucleosomes, which arrange in higher organization structures called chromatin fibers.
Subsequently, chromatin fibers condense to form structures called chromosomes.
A triploid organism (3n) contains three sets of homo-logous chromosomes, each one containing one allele for a given locus.
In conclusion, the process involved in genetic recombination is INDEPENDENT ASSORTMENT. The correct order from smallest to largest is DNA, nucleosomes, chromatin, chromosomes. In a triploid organism, there are 3 ALLELES for each gene per cell.

Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).

Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

how does an increase in volume affect the gas pressure in a balloon
Answer:
Boyle's Law explains the relationship between volume and pressure. According to Boyle's Law, the volume of a fixed amount of gas decreases as its pressure increases. If the volume increases, its pressure decreases.
A key part of the Watson-Crick model came when Watson realized
that adenine could form hydrogen bonds with thymine and guanine
could form hydrogen bonds with cytosine. This explains why A=T
and G C in Chargaff's rules. Also, these two hydrogen-bonded
nucleotide pairs had the exact same width, so they could form the
rungs of the DNA ladder.
The fact that these pairs could match up only in this way meant that
the sequence of bases in one strand could determine the sequence
of bases in a second strand created from the first. The second strand
is said to be complementary to the first strand. Individual bases are
paired so that the identity of any base determines the identity of the
base paired with it; that is, the complementary base.
This table lists the base abbreviations for bases in a sample of single-
stranded DNA. Fill in the second column with the base abbreviations
that are complementary to the given bases.

In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick defined DNA as a double helix that contained long, helical strands wound together. In their model, every DNA strand contained personal devices referred to as bases, and the bases alongside one DNA strand matched the bases alongside the opposite DNA strand.

.A jogger with a mass of 81.6 kg is moving at 2.2 m/s. What is the jogger's
kinetic energy
Answer:
89.6Joules
Explanation:
Kinetic energy is 1/2MV^2
Where m is Mass and v is velocity.
M=81.6 v=2.2m/s
K.E= 1/2 × 81.6 × 2.2
= 81.6 ×1.1
K.E=89.6 Joules
