Answer:
Trisomy X, also known as triple X syndrome and 47,XXX, is characterized by the presence of an extra X chromosome in each cell of a female. Those affected are often taller than average.
Klinefelter syndrome (sometimes called Klinefelter's, KS or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby.

Which of the following describes the result of independent
assortment and crossing over during meiosis?
A: it creates genetic differences in sperm and egg
B: it produces higher quantities of sperm and egg
C: it produces individuals that are very similar to their parents
D: it makes fertilization go smoothly
Answer:
A.)
Explanation:
Independent assortment and crossing over is important because it creates genetic variation between gametes. This immediately eliminates (C) and in no way does crossing over or independent assortment cause more gametes to be produced so cross out (B). Only (A) and (D) is left, while both answers makes sense, (A) is the better one.
Meiosis takes place in the germ cells and give rise to haploid gametes. Due to the events including crossing over and independent assortment, it causes genetic differences in sperm and egg, i.e., option A.
What is crossing over?Chromosomal crossover also referred as crossing over, represents the exchange of genetic material during gamete formation,
It occurs between two non-sister chromatids of homologous chromosomes that results in recombinant chromosomes.
This creates genetic differences in the sperms and eggs.
Thus, the correct option is A.

Answer:
Terrestrial ecosystems are known for their diversity; they are grouped into large categories called biomes. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them. For example, there is great variation in desert vegetation: the saguaro cacti and other plant life in the Sonoran Desert, in the United States, are relatively abundant compared to the desolate rocky desert of Boa Vista, an island off the coast of Western Africa

Examine the table that highlights the structural similarities and differences between four cell types. One student (Student 1) claims that cell l is the most distantly related to eukaryotic cells while another student (Student 2) claims that cell lll is most distantly related to eukaryotic cells. Which explanation is most accurate between these two contrasting claims?
A) Student 1 has an explanation that is supported because eukaryotic cells do not have linear chromosomes.
B) Student 2 has an explanation that is supported because eukaryotic cells can not have single chromosomes as their genome.
C) Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is lacking completely in cell III.
D) Student 1 has an explanation that is supported because eukaryotic cells are not photosynthetic, so it cannot be closely related to eukaryotes.
Answer:
C) Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is lacking completely in cell III.
Explanation:
The explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.
What is the significance of the nucleus?The nucleus is present in the eukaryotic cell while it is absent in the prokaryotes, and in the nucleus are the enzymes for DNA replication, transcription, and so on that can make the DNA and the mRNA, as well as the genetic contents. The nuclear membrane acts as a barrier between the genomic contents and the cytoplasm, and transportation takes place through it.
Hence, the explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.

Which has greater momentum, a 2.0kg hockey puck moving east at 2.5m/s or a 1.3kg hockey puck moving south at 3.0m/s?
A hockey puck weighing 2.0 kg has more momentum.The monentum will be larger the bigger the mass/velocity.
The relationship between momentum and an object's mass and speed is direct. Hence, an object's momentum increases with increasing mass or velocity. It is based on the speed and mass of the car. The monentum will be larger the bigger the mass/velocity.
P= East puck/mv
P = (2.0kg)(2.5m/s)
P= 5.0kgm/s
P= South puck/mv
P= (1.3kg)(3.0m/s)
P= 3.9kgm/s
Both cars will have identical momentum if they have the same mass and speed. The Momentum Calculator employs the formula p=mv, as well as momentum (p) is equivalent to the weight (m) times velocity . Any two of a values can be used by the calculator to determine the third. While lighter things have less momentum, massive ones have had more momentum for just a given speed. Because of this, stopping a loaded truck requires more effort than stopping an empty one.

5c. Two parents, a heterozygous normal female and a male who is
colorblind, want to know HELP PLSSS!!! the percentage of their MALE offspring that could
be colorblind. What is the expected percentage? *
0%
25%
50%
75%
100%
Answer and Explanation:
We can assume that being colorblind is a recessive trait.
That means the father has a genotype of both lowercase letters, denoted as bb.
Let's make a chart.
- The Father's Genotype is bb
- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))
b b
B| Bb | Bb |
b| bb | bb |
We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.
That means the expected percentage is 50%.

Compare and contrast inhalation and exhalation in terms of what takes place between the lungs
and the diaphragm muscle.
During inhalation, the diaphragm contracts. As it contracts, the diaphragm moves downward, increasing the volume within the thoracic cavity. Due to this increased volume in the thoracic cavity, a negative pressure gradient is generated which causes air to flow from the environment into the lungs. The lungs expand as the alveoli of the lungs fill with air.
During exhalation, the diaphragm relaxes and rises into the thoracic cavity, decreasing the volume in the thoracic cavity. The decreased volume in the thoracic cavity results in an increased pressure which causes air to flow from the lungs out to the environment. At the same time, the lungs are elastic and act to help air flow out as the retract after being expanded.

Variations between organisms are caused by differences in
Answer:
Genetic variation occurs because beneficial traits exist in a collection of genes, and gene flow makes these traits more prevalent in populations.
Further explanation
Genetic diversity is a level of biodiversity that refers to the total amount of genetic variation in the whole species that inhabits some or all of the earth's surface that can be inhabited.
Genetic diversity uses several simple measurements:
Gene diversity is the proportion of polymorphic loci throughout the genome.
Heterozygosity is the average number of individuals with polymorphic loci.
Alleles per locus, also used to demonstrate variability.
