pThe probability of having an offspring with both the dominant phenotypes for both genes is equal to the product of the individual probabilities. This means, the probability of having a dominant phenotype for both traits would be
The product probability rule states P(A∩B) = P(A) x P(B). In the exposed example, the probability of having a dominant phenotype is 9/16.
What is the product probability rule?The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.
It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.
This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.
For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is
P(A∩B) = P(A) x P(B)
The probability of inheriting one of the alleles from each parent is 0.5 (beacause each parent has two alleles).
According to this, the probability of having a dominant phenotype for both traits depends on the paretal genotypes.
For instance, let us analyze the cross between two dihybrid individuals AaBb x AaBb.
Assuming the involved genes code for different traits and both are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype and phenotype we are interested in (A-B-)

If there are 32 sister chromatids in a normal somatic cell, how many chromosomes are there?.
If there are 32 sister chromatids in a normal somatic cell, the number of chromosomes there are 16 chromosomes. Each chromosome contain of 2 sister chromatids.
How many chromosomes are in a sister chromatid?Each daughter cell will have half of the initial 46 chromosomes, or 23 chromosomes. Each chromosome contain of 2 sister chromatids.
The daughter cells drive in to the third and final stage of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
Thus, the number of chromosomes there are 16 chromosomes, as Each chromosome consists of 2 sister chromatids.

Compare and contrast how are variations and adaptations similar? how are they different?
Adaptions are basically add-ons and/or updates while variations are like different types.
A particular gene has two alleles, a dominant allele A and a recessive allele a. The frequency of allele A is 0.55. If the population is in Hardy-Weinberg equilibrium with respect to the gene, then what is the expected frequency of genotype Aa
If p = frequency of A and q = frequency of a, then assuming H-W equilibrium we have
p + q = 1 ⇒ q = 1 - p = 1 - 0.55 = 0.45
Then the expected frequency of the heterozygous genotype Aa is 2pq = 2 • 0.55 • 0.45 = 0.495.

Without land regulations to protect rainforests, land continues to be destroyed using slash and burn methods. Which global need is increasing the rates of rainforest deforestation?
Local farmers need for new land
Global demand for natural gas
Country's demand for precious metals
Demand for palm oil from other countries
Answer: Local farmers need for new land
Explanation Forests are cut down to clear land for agriculture, livestock grazing, and settlement; for timber; to produce charcoal; and to establish tree plantations.
Deforestation occurs across all forest types, but is concentrated in the tropics and boreal regions. Temperate regions are experiencing a net increase in forest cover due to natural regeneration.
While deforestation produces food, fiber, and fuel, it can also pose risks to climate, biodiversity, and food security by degrading the ecosystem services normally afforded by healthy and productive forests.
The global need that is increasing the rates of rainforest deforestation is demand for natural gas. The correct option is B.
What is natural gas?Natural gas is a naturally occurring mixture of gaseous hydrocarbons, primarily methane, with minor amounts of other higher alkanes.
Low levels of trace gases such as carbon dioxide, nitrogen, hydrogen sulfide, and helium are also commonly present.
Natural gas is formed naturally over hundreds of millions of years. Layers of decomposing plants and animals are subjected to intense heat from the Earth and pressure from rocks to form it.
Land continues to be destroyed using slash and burn methods in the absence of land regulations to protect rainforests. The global demand for natural gas is driving up rates of rainforest deforestation.
Thus, the correct option is B.

Explanation:
The life cycle of a star is considered/named, stellar evolution.
1. Introduction – this is where you explain to your audience why you are making this presentation/video/booklet. You will explain what it contains, as you would for an English essay, etc.
2. Explain coastal processes – erosion, transportation, deposition.
3. Explain two landforms – one erosion, one deposition – how they are formed and include an example(s) of where you can find this feature.
4. Explain the relationship between humans and the coast – how we benefit from the coast and how we can damage the coastline, and visa versa (e.g., coastal erosion, longshore drift that changes the shape)
5. Explain coastal management strategies and include a case study (an example) of a location where coastal management strategies have been put in place
6. Conclusion – as you would for your English essays.
Answer:
1.The processes of erosion, transportation and deposition occur as a result of differing wave and current energy,Where marine energy is high, disintegration, expulsion and transportation is bound to occur.
2.Erosion refers to the breaking down of the land by the force of waves. Transportation is the work of waves and tides in transferring this broken material somewhere else and deposition refers to the process by which waves and tides lose energy, cease to transport and release eroded material.
3.Erosional landforms include V-shaped valleys, interlocking spurs, waterfalls and gorges. Meanders and oxbow lakes are formed from erosion and deposition. Depositional landforms include floodplains.
4.The ‘blue economy’—a term that has emerged in the past decade—attempts to embrace the opportunities associated with the ocean, whilst recognising, accounting for and addressing the threats posed by such an economy. It is essentially the ocean equivalent of the ‘green economy’—a vision for a decarbonised, regenerative and more equitable economic system.
The ‘blue economy’ gained prominence at the 2012 UN Convention on Sustainable Development (UNCSD), or Rio+20 conference, when small island developing states began emphasising the importance of the ocean and marine economy in response to land-focused calls for a ‘green economy’
5.Coastlines are being eroded by waves and the weather.
Coastlines need to be managed because they are often used by humans for purposes such as housing.
To protect the coast from erosion, we can use hard engineering strategies (building man-made structures such as sea walls) and soft engineering strategies (using natural processes such as beach nourishment).
6.A conclusion is, in some ways, like your introduction. You restate your thesis and summarize your main points of evidence for the reader. You can usually do this in one paragraph. In the following example, the thesis statement is in bold. Notice that it is written in 2 sentences.
