12. ( Figure is the first picture: Refer to the figure showing a pedigree of a family affected by a sex-linked recessive disorder. If a female is a carrier for a sex-linked recessive disorder, is it possible for her sons to be unaffected by the disorder? Choose the best answer and explanation.
A. Yes, this is possible. Males receive an X chromosome from their mother. If their mother is a carrier, a male has a 50 percent chance of being affected by the disease and a 50 percent chance of being unaffected.
B. No, this isn't possible. If a mother is a carrier of an X-linked recessive disorder, her sons will be affected by the disease and her daughters will be carriers of the disease.
C. No, this isn't possible. X-linked recessive disorders can't "skip" generations like other genetic disorders.
D. Yes, this is possible. Males receive an X chromosome from their mother. If their mother is a carrier, the mutated X chromosome won't be passed on to sons and so they'll be unaffected.

20. C.
Explanation:
11. Codominance is a non-mendelian inheritance pattern. It is when two dominant traits are inherited and both are expressed in the organism. Because both are dominant, a blended expression of the trait results in the off-springs.
12. Look at the cross for this problem below:
XHXh and XHY
XH Y
XH XHXH XHY
Xh XHXh XhY
The mother is a carrier, so that means she is heterozygous for the trait hemophilia. Look at the sections with XY. We see that a son can inherit the recessive trait and the other does not.
13. The two main stages of the cell cycle would be interphase and mitosis. Interphase is the phase of the cell-cycle where the cell prepares for cell division. It is at interphase where DNA is duplicated and the cell grows. Mitosis is the actual phase where division takes place.
14. The Human Genome Project or HGP is a collaborative research program that aims to determine the COMPLETE sequence of the human DNA and to identify the locations of the genes in the sections of all chromosomes. It also aims to create maps that link inherited traits across generations.
15. Recombination is a genetic process where DNA is broken down and then recombined to poduce different traits in the off-springs. This can be done between different organisms to produce combined traits.
16. From mRNA, the sequence is translated by the tRNA or transfer RNA. The tRNA carry amino acids that code for specific sequences. These amino acids are the building blocks of proteins.
17. 3-letter sequences in mRNA code for a specific amino acid. These are collectively known as codons. These codons match up with anti-codons of tRNA which code for specific amino acids.
18. For this problem, you did not provide a Punnet but I can help you out by showing you the different possible crosses because the answer would depend on the cross. Look at the attached image.
If your problem is like CROSS 1 then the answer would be 75 percent would be Purple and 25 percent would be white.
If your problem is like CROSS 2 then the answer would be ALL will be purple.
If your problem is like CROSS 3 or CROSS 4, the answer would be half of the offspring will have purple and half would have white.
19. Cells interact with other cells nearby and throughout the body depending on what needs to be done. Cells can interact with nearby cells directly, or they can do this chemically or through other processes as well, especially when they are far apart.
20. Females receive X chromosomes from both parents. Females have a pair of X chromosomes. Going back to your problem, because the trait is recessive and the mother is only a carrier and the father is not a carrier, the chances of a female off-spring inheriting the trait would be 50%. You can look at the cross below:
XHXh and XHY
XH Y
XH XHXH XHY
Xh XHXh XhY
As you can see in the cross, one of the daughters did not receive the recessive trait XHXH.
Over time, rocks begin to break down to form soil. Which of the following is a way that rocks can be broken down?
A.
wind erosion
B.
an eclipse
C.
thunder
D.
a full moon
Answer: wind erosion
Explanation:
The correct answer is A. Wind erosion
Explanation:
The soil is the substance that covers the surface of our planet, this is mainly formed as rocks break down which is called weathering. This phenomenon can occur due to the action of living organisms, due to chemical reactions or due to physical factors. In the case of physical factors, this includes collision, changes in temperature or pressure and wind erosion that occurs as the wind makes rocks and soil move and this movement can make rocks break down into smaller parts or become more prompt to break. Thus, one of the ways rocks can be broken down is through wind erosion.

How are sex-linked traits inherited?
Answer:
C
Explanation:
Regions of the sex chromosomes in the parents cross over, thus creating new traits in the offspring.
Alleles are passed from the parents' sex chromosomes to the sex chromosomes in the offspring.
Sex-linked traits are traits that are determined by genes located on the sex chromosomes (X and Y chromosomes). In humans, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
When it comes to the inheritance of sex-linked traits, the key factor is the sex of the parent transmitting the gene to the offspring. For traits located on the X chromosome, the inheritance pattern is as follows:
If a father carries a sex-linked allele on his X chromosome, he can only pass it on to his daughters because he passes his Y chromosome to his sons. Thus, daughters have a 50% chance of inheriting the allele, while sons will not inherit it.
If a mother carries a sex-linked allele on one of her X chromosomes, she can pass it on to both her sons and daughters. Daughters have a 50% chance of inheriting the allele from their mother, and sons have a 50% chance of inheriting the allele from their mother as well.
Examples of sex-linked traits in humans include color blindness and hemophilia, both of which are located on the X chromosome.
It is important to note that the inheritance patterns for sex-linked traits differ from those of traits located on autosomes (non-sex chromosomes). For autosomal traits, both parents can equally pass on alleles to sons and daughters, with each offspring having a 50% chance of inheriting the allele from each parent.

Bobbie took this picture of the Grand Canyon. How was this canyon most likely formed? A) lava B) deposition C) wind erosion D) water erosion
Answer:
D
Explanation:
Water Erosion formed the canyon as it broke down sediments
The image for the question is not given and it is not available anywhere. However, the question can still be answered since the Grand canyon formation process is well known. The correct answer is given below-
Answer:
Option (D)
Explanation:
The Grand Canyon is one of the most beautiful features on earth. It is about 450 kilometers long and comprised of steep slopes. The Colorado River flows through the rocks of the canyon. This canyon is comprised of mostly sedimentary rocks such as sandstone, shale, and limestone and also metamorphic rocks are found. As the river flows, it cuts the softer sedimentary rocks that gave the shape and structure of the Grand Canyon. The river has been flowing through the canyon about 5 to 6 million years back.
Thus, the Grand Canyon was formed due to water erosion.
Hence, the correct answer is option (D).

Why are most of Earth's deserts located in the subtropical zone?
A. These regions receive more sunlight than the equatorial region.
B. These regions receive less sunlight than the equatorial region.
C. These regions are very warm but less humid than other regions.
D. These regions are very warm but more humid than other regions.
Most Earth's deserts are located in the subtropical zone because of atmospheric high-pressure systems that inhibit cloud formation and precipitation, leading to very dry conditions with low humidity.
The reason most of Earth's deserts are located in the subtropical zone is because of atmospheric circulation patterns and the associated high-pressure systems that exist between 15° and 30° north and south latitude. These high-pressure areas are characterized by descending dry air, which inhibits the formation of clouds and precipitation, leading to dry conditions. Furthermore, the presence of mountain ranges often leads to the formation of a rain shadow on the lee side, where deserts like the Mohave and Sonoran can be found. These geographic factors contribute to making subtropical deserts very dry because they receive low annual precipitation. High evaporation rates and variable and unpredictable rainfall define these deserts, such as the Sahara and the Namib.
Thus, the correct answer to the student's question is C: These regions are very warm but less humid than other regions.

What happens to the nitrogen in a rabbits body
when it dies
Answer:
When rabbit dies, the nitrogen in the rabbits body is released into the soil by decomposition.
Explanation:
When rabbit dies its body is decomposition takes place. Decomposition is process of breaking down of the dead remains of the plants, animals and insects into tiny pieces by free living bacteria, fungi and worms present in the environment .
During the decomposition process the nitrogen present in the dead rabbit body is released into the soil in the form of ammonia. The bacteria(nitrifying bacteria) present in the soil converts this ammonia into nitrates so that it can be again used by the plants. Now plants intakes this nitrates for photosynthesis process. This process of fixing nitrogen back into the atmosphere is called nitrogen cycle.
Final answer:
When a rabbit dies, the nitrogen in its body undergoes catabolism, or breakdown, along with other macromolecules. Mammals like rabbits convert the toxic ammonia into urea through the urea cycle, which is then excreted in their urine.
Explanation:
When a rabbit dies, the nitrogen in its body undergoes catabolism, or breakdown, along with other macromolecules. During this breakdown, carbon, hydrogen, and oxygen are extracted and stored in the form of carbohydrates and fats, while excess nitrogen is excreted from the body. To detoxify the nitrogenous waste, mammals like rabbits convert the toxic ammonia into urea through the urea cycle. Urea is then excreted in their urine.
Alicia is listening to a song on the radio. Which atmospheric layer allows her to hear the song?
ionosphere
troposphere
mesosphere
stratosphere
Answer:
The ionosphere allows Alicia to her the song on radio.
Explanation:
The ionosphere is in the upper atmosphere. It affects the propagation of radio waves because is where sufficient ionization can exist. The radiation from the sun in this layer ionizes atoms and molecules here, the molecules liberate electrons and they create a space of free electron and ions.
Radio waves are affected by the ionosphere because radio waves in this frequency range are effectively reflected by the ionosphere, they don´t penetrate through the atmosphere. This reflections enable wave propagation large distance.
The ionosphere affects the radio spectrum from low frequencies up to super high frequencies.

Macromolecules is to carbohydrate, as nucleotide is to
Answer:
a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
Explanation:
Macromolecules are to carbohydrates as nucleotides are to nucleic acids.
In Biology, macromolecules are large molecules formed by the polymerization of smaller units called monomers. A carbohydrate is a type of macromolecule made up of monomers called monosaccharides. Similarly, a nucleic acid is a type of macromolecule made up of monomers called nucleotides.
A nucleotide is a small molecule consisting of a sugar, a phosphate group, and a nitrogen base. Nucleotides are linked together to form long chains called nucleic acids, such as DNA and RNA. This relationship is similar to how monosaccharides link to form carbohydrates.
Therefore, just as a carbohydrate is a type of macromolecule, a nucleotide is a building block of nucleic acids.

His muscle cells have experienced ______________ that led to production of _______________.
Answer:
Anaerobic respiration; lactate
Explanation:
By utilizing the previous knowledge about respiration i am answering the question in one of the possible ways.
Anaerobic respiration is considered to be the process in which cells respire in absence of oxygen. During this, glucose molecules are broken down to produce energy along with the production of lactic acid. This process is used by small organisms as well as eukaryotic cells at the time of need such a s strenuous exercise (when oxygen supply is low )to produce energy. When the production of lactic acid is high during anaerobic respiration, this leads to production of more energy in form of ATP which side by side causes pain in muscles and a condition called muscle cramps.
Hope it helps!

anaerobic respiration; lactate
the niche of an animal is best defined as?
A. all the way an animal fits into its environment
B. the number of individuals of the species the environment will support
C. the same as its lifespan
Answer:
A. all the way an animal fits into its environment.
Explanation:
The niche of an animal encompasses all the ways it fits into its environment, including its role and interactions with biotic and abiotic factors. It also involves the habitat or physical environment to which the species is adapted.
The niche of an animal is best defined as all the ways an animal fits into its environment. This multi-dimensional space details the role and position of a species within its ecosystem and includes several key parameters such as the essential resource limits, and the species' interactions with both biotic and abiotic factors. Another critical aspect of a species' niche is its habitat, which is the physical environment to which it has become adapted and where it can survive. This environment is generally described by abiotic factors like sunlight, temperature, and precipitation, all of which play a role in the survival and characteristics of the species.
A species' niche involves a range of environmental factors that allow it to survive and reproduce, which may include specific climate conditions, interactions with other species, and access to resources. For instance, a particular tree species' niche may include the ability to live within a certain temperature range, receive a minimum amount of precipitation, and rely on certain fungi for root health. Therefore, the function or occupation of a life-form within a community that is a niche combines an organism's physical, chemical, and biological interactions within its environment.
