Explain what happens at each of the following boundaries: ocean/ocean
convergent, bcean/continental convergent, continental/continental
convergent, divergent and transform plate boundaries.
Answer:
The particularly severe winter of 1777-1778 proved to be a great trial for the American army, and of the 11,000 soldiers stationed at Valley Forge, hundreds died from disease. However, the suffering troops were held together by loyalty to the Patriot cause and to General Washington, who stayed with his men.
Explanation:
Explanation:oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates.
Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed. The convergent boundaries between ocean and continental plates create subduction zones. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite.
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates. The Granite and recycled material are much lighter than the heavy basalt layers of the ocean plates.

How does potassium chloride (KCI) trigger spawning when injected in sea urchins? Changes the ion concentration inside the urchin, so the urchin pulls in seawater that presses on gonads Mimics environmental signals in seawater that trigger spawning Triggers the muscles surrounding the gonads to contract 0 Acts as an irritant that the urchin tries to expel by spawning
Potassium chloride (KCI) triggers spawning in sea urchins by mimicking environmental signals and altering ion concentration.
Potassium chloride (KCI) induces spawning in sea urchins through a combination of factors. Firstly, when KCI is injected into a sea urchin, it alters the ion concentration within the urchin's body. This change in ion concentration triggers a response where the sea urchin pulls in seawater, resulting in increased pressure on the gonads. This increase in pressure mimics the natural environmental signals present in seawater that normally stimulate spawning in sea urchins.
Secondly, KCI acts as an irritant to the sea urchin. The injection of KCI into the urchin's body causes discomfort, and the urchin tries to expel the irritant by spawning. This expulsion mechanism is a natural response to potentially harmful substances within the body.
Lastly, potassium chloride also triggers the contraction of the muscles surrounding the gonads. The contraction of these muscles helps to expel the gametes during spawning. By inducing muscle contractions, KCI plays a direct role in initiating the release of eggs or sperm.
In summary, potassium chloride (KCI) triggers spawning in sea urchins by altering the ion concentration within the urchin's body, mimicking environmental signals that normally trigger spawning, and initiating muscle contractions. These processes collectively stimulate the sea urchin's reproductive system and lead to the release of gametes.

assuming that p = 0.3 for a population in hardy-weinberg equilibrium, what would be the expected frequency of heterozygotes for the involved allelic pair? enter your answer as a decimal to two places.
The expected frequency of heterozygotes for the involved allelic pair in a population in Hardy-Weinberg equilibrium with p = 0.3 can be calculated.
In Hardy-Weinberg equilibrium, the frequency of heterozygotes can be determined using the equation 2pq, where p represents the frequency of one allele and q represents the frequency of the other allele. Since p = 0.3, q can be calculated as 1 - p, which is 0.7.
Therefore, the expected frequency of heterozygotes can be calculated as 2 * 0.3 * 0.7 = 0.42.
The expected frequency of heterozygotes for the involved allelic pair in the population is 0.42, represented as a decimal to two places.
It is important to note that the Hardy-Weinberg equilibrium assumes certain conditions, such as no migration, genetic drift, mutation, or natural selection. In reality, populations rarely meet these conditions exactly, but the Hardy-Weinberg principle provides a useful baseline for studying genetic equilibrium in populations.

You notice that your aunt, who has generalized anxiety disorder, is often restless and has trouble concentrating. Which area of her brain is most likely responsible for her responses to anxiety-provoking events? A. Amygdala B. Hypothalamus C. Anterior cingulate cortex D. Cingulate gyrus
Answer:
Amygdala
Explanation:
Generalized anxiety disorder (GAD occurs when an individual experiences excessive and continuous worry and anxiety about certain things ,It is caused by over activation of the region of the brain that mediate response to fight and flight stimulus and fear,the amygdala.
Its symptoms are difficulty with concentrations, overthinking ,indecision, irregular sleep patterns.
Two brain circuits transmitted sensory stimuli of fear or danger in the brain to two regions of the brain,
1. the peripheral cerebral cortex for voluntary decisions
2. the Amygdala for involuntary emotional decision.
The amygdala is concerned with how the body reacts to the effects of the stimuli in the immediate environments, the interactions of the stimuli with the emotions of the subject, and the involuntary response .
To respond to the stimuli of fear. The amygdala stimulates the hypothalamus.The latter activate the cardiovascular and breathing centre .Hence,adrenaline is released into the blood stream.The increases involuntary response to anxiety,which gives a fast response..The cerebral cortex response takes time to relay response.
Amygdala, stores memories of all emotions, fear, and anxiety. In patients with this disorder, the Amygdala is sensitive and had been adapted to the memory of fear and anxiety stored.Therefore, every slight normal event which should give any danger is over reacted to by the amygdala with fear or flight response, This triggers the two brain circuits to give anxiety-provoking events.

What are persistent pesticides?Organochlorine pesticides, which make up the majority of persistent pesticides, are so-called because of their environmental stability and resistance to deterioration. It is possible to assess persistence by grouping pesticide half-lives into three categories. These fall into three categories: low (16 days or less) moderate (16 to 59 days), and high (over 60 days). Because they are significantly less likely to linger in the environment, pesticides with shorter half-lives tend to accumulate less.
Are pesticides persistent pollutants?Organochlorine pesticides like DDT, industrial chemicals, polychlorinated biphenyls (PCB), as well as unintended byproducts of numerous industrial processes, including polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF), often known as dioxins, are the most frequently encountered POPs.

A rock has been formed by the accumulation of bits of minerals and soil that are pressurized together. How should this
rock be classified?
O organic rocks
Igneous rocks
O sedimentary rocks
O metamorphic rocks
A rock that has been formed by the accumulation of bits of minerals and soil that are pressurized together is a sedimentary rock.
Sedimentary rocks are formed when sediment, such as bits of minerals and soil, are deposited and compacted over time. This can happen when these materials are transported by water, wind, or ice, and then settle in layers. The pressure of the overlying layers can then cause the sediment to compact and form a rock.
Sedimentary rocks can also be formed when the remains of plants and animals are buried and then fossilized over time. These rocks are called sedimentary rocks because they are made up of sediment that has been deposited and compacted over time.
In contrast, igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Metamorphic rocks are formed when existing rocks are subjected to high temperatures and pressures, which cause them to change in texture and composition. And organic rocks are formed from the remains of plants or animals.
