DNA is a nucleic acid involved in heredity, or the passing down of genetic traits from one generation to the next. DNA consists of four different types of nucleotide monomers.Which part of the nucleotides' structure is responsible for the incredible variation that exists amongst all types of organisms
Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-Adenine is paired with Thymine (think of A for apple and T for tree)
-Cytosine is paired with Guanine (think of C for car and G for garage)

When the tetrads are formed
during meiosis, what is the
benefit of crossing over?
A. The chromosomes double in number.
B. The chromosomes exchange genetic
information.
C. The chromosomes are reduced by half.
Answer:
B. The chromosomes exchange genetic information.
Explanation:
Crossing over of tetrads during meiosis is very important for the exchange of genetic information.
This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.
Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.
So, the correct answer is B. The chromosomes exchange genetic information.
Type of symbiosis Suppose friendly ants fed on sugary droplets excreted from a caterpillar, but did nothing to help the caterpillar. Assuming that taking the sugar does not hurt the caterpillar, what type of symbiotic relationship is this
Answer:
Commensalism
Explanation:
All organisms in nature interact with other organisms in different ways. Symbiotic interactions involve a relationship between two or more organisms of different species in which one or all of them turn to be beneficiated by that relationship. These species create permanent mutual dependence.
Symbiotic interactions include:
• Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of the organisms seems to be strongly affected by the other one. Meanwhile, the other organism does not seem to be affected at all.
• Commensalism: In this case, the fitness of only one of the species seems to increase, while the other species is not affected at all, nor positively or negatively. The unaffected species might provide food or refuge to the other species, which is benefited.
• Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mainly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death.
• Mutualism: The interaction is favorable for both species. Their fitness increases with these interactions, although they do not need this relationship to survive. The degree of benefits might vary among species or might be equal.
-----------------------------------------------------------------------------------------------------------
The exposed symbiotic example is a commensalism case. The ant is benefited from taking the sugary droplets. Its fitness increases. But ants do not make any harm to the caterpillar. In fact, it has no effect on them at all, no possitive nor negative. The caterpillar´s fitness is not influenced by the ant.

#5 Two people are both unknowingly carriers for the cystic fibrosis gene. What is the probability that they will have children with cystic fibrosis?
Answer:
Explanation:
A woman who is a carrier for #1 hemophilia and a man that does not have the condition have children. What is the probability that they will have a child with the condition being studied? What is the gender of that child?
if the baby gets the Y chromosome from the father it will be a boy. If the boy gets his mother's X chromosome with the hemophilia gene he will have hemophilia. If he inherits his mother's other X chromosome, he will have normal blood clotting. If the baby gets the X chromosome from the father it will be a girl.
#4 A woman that is heterozygous for type A blood and a man that is heterozygous for type B blood have children. What are the possible blood types of their children?
One parent with A and another with B can produce a child with A, B, AB or O blood types.
#5 Two people are both unknowingly carriers for the cystic fibrosis gene. What is the probability that they will have children with cystic fibrosis?
If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.
#3 A woman that is heterozygous for Huntington's disease and a man that does not have the condition have children . What is the probability that their children inherit the Huntington's gene ?
Huntington's disease (HD) is what is called a dominant genetic disease. What this usually means is that a child only has a chance of getting a disease like this if a parent has it too. But parents without HD can have a child with HD. This is true of any dominant genetic disease
Which of the following changes to Earth is caused predominantly by living organisms?
A. The production of dirt.
B. The release of free nitrogen into the atmosphere.
C. The release of sulfur dioxide into the atmosphere.
D. The movement of air currents by convection cells.
The production of dirt is cause predominantly by living organisms
This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.
What is Pollution?Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.
These pollutants can be both natural and anthropogenic.
Natural pollutants are volcanic ash, river sediments
Anthropogenic pollutants are chemicals released from industries vehicular emission.
Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.
Effects of pollution on environment:
1. Biomagnification describes situations where toxins (such as heavy metals) passes through trophic levels, becoming exponentially more concentrated in the process.
2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.
3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.
4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.
5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.
6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.
7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.
Rest three options are majorly natural process.
Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.
Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.
Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0
2 19 0.2248 15.7
23 7 0.1331 9.3
SUM: 70 1.0000 70.0
What are the calculated and critical values for this test?
a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.
Answer:
d. calculated = 3.10; critical = 7.815.
Explanation:
To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :
The test statistic is defined as :
χ² = Σ(Observed - Expected)² / Expected
Observed = number of nests
χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)
χ² = 3.1089
The critical value :
df = n - 1 = 4 - 1 = 3
The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

If you compare the histone modifications at the imprinting center on the maternal and paternal chromosomes, you would expect to see ____________ on the maternal chromosome and ____________ on the paternal chromosome.
a. activating marks like H3K9 acetylation; silencing marks like H3K9 methylation
b. silencing marks like H3K9 methylation; activating marks like H3K9 acetylation
Answer:
b. silencing marks like H3K9 methylation; activating marks like H3K9 acetylation
Explanation:
Genomic imprinting is an epigenetic phenomenon that leads to parent-of-origin-specific monoallelic expression, thereby genes under imprinting are differentially expressed depending on their parental origin. Genomic imprinting involves DNA methylation, histone modification such as histone 3 lysine 9 methylation (H3K9) and non-coding RNA regulatory epigenetic pathways, which act together to silence one parental gene form or 'parental allele'. Maternal imprinting occurs when the maternal allele is silenced (usually caused by methylation of the maternal allele), whereas paternal imprinting occurs when the paternal allele is silenced (methylation of the paternal allele). Moreover, H3K9 acetylation is connected with active promoters (gene transcription). The imprinted genes are generally grouped in genomic regions called imprinting centers (ICs) that regulate gene expression according to the parental origin.
Basidia within a basidiocarp are obvious for mushrooms, but this may not be as obvious for other examples that you have observed. For each of the examples of basidiomycetes that you have observed, speculate about the location of structures analogous to the basidia observed in mushrooms. Think about the formation of spores by meiosis.
a. bird's-nest fungi
b. common puffballs
c. earthstar puffball
d. shelf fungi
e. corn smut
Answer:
Birds nest fungi: Basidicarp, a cup shaped with several lenticular bodies appear as bird's nest with eggs. The eggs are called the peridioles and the nest serves release the eggs onto the twigs or branches and spores are liberated .
common puffball: The young fruit body is covered with whitish spines that become mark of scar after maturity.
Earth star puff balls: The fruiting body is in the shape of an egg, it has an outer part that separates away from the inner basidiocarp and splits into several rays which curve backwards and resembles a star.
shelf fungi: The fruiting body develops on the tree trunks and termed conk which are tough and leathery often plate-like growing out of the tree trunks.
corn smut: The diploid teliospores germinate and undergo meiosis to result in four haploid basidiospores.
