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

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)

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.

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.

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

Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.

-------------------------------------

Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.

Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.

It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.

It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.

I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.

II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.

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.

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.
