Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139

Answer:
B.) The atoms in the molecules before the photosynthesis reaction were rearranged to create new molecules
Explanation:
Choice A and D are just flat out wrong. While choice C seems more opinionated. I don't know the exact facts behind choice C, since it's been a while since the last time I took Bio, but the question asks what can you conclude from the DIAGRAM. Which means that basic test taking skills would rule out choice C, since there's no way that you can determine which element is the most "important" in that diagram—or any scientific diagram tbh lol it'd just be uncharacteristic.

A species was added into a particular ecosystem to control the population of a prey species. This method of introducing a new species is called (biological augmentation) , (bioremedation) , or (reforestation). The population of the added species increased, leading to an imbalance in the ecosystem. This increase happened because (the competition for resources increased in the ecosystem) , (the population of prey species increased in the ecosystem) , or (the amount of resources increased in the ecosystem).
Answer:
A species was added into a particular ecosystem to control the population of a prey species. This method of introducing a new species is called bioremediation. The population of the added species increased, leading to an imbalance in the ecosystem. This increase happened because the competition for resources increased in the ecosystem.
Explanation:
The method of introducing a new species into an ecosystem to control the population of a prey species is called "biological augmentation" but in the given scenario, the population of the added species increased, leading to an imbalance in the ecosystem.
Biological augmentation is a method of introducing a new species into an ecosystem to control the population of a particular species that is causing problems. For example, if a particular species is overpopulating and causing damage to an ecosystem, introducing a predator or parasite that preys on that species can help control its population.

Select the correct answer. Which of the following has become today’s major cause of mass extinction? A. Adaptive radiation B. Human activities C. Addition of new species
Answer:
Human activities, by us doing certain things like cook outs and parties, we lack the sense to clean up after ourselves or to put other species into consideration.
Explanation:
Mass extinction is the rapid vanishing of the organism from the planet due to some extreme conditions. Human activities can be the major cause of mass extinction.
What are adaptive radiation and human activities?Human activities like deforestation, burning of fossil fuels are aiding the global warming process that results in the alteration of the climatic conditions.
The change in the climate and increased global warming are the major causes that have led to the endangerment and extinction of many species and will be the major cause of mass extinction.
Adaptive radiation is the ecological process in which the species diversifies to form a new group of the organism of a particular niche. It will not contribute to mass extinction.
Therefore, option B. human activities can be the cause of mass extinction.

What situation is an example of equilibrium
Answer:
Answer is the amount of water in a cup doesn't change.
Explanation:
"Equilibrium is achieved when the state of a reversible reaction of opposing forces cancel each other out. While in a state of equilibrium, the competing influences are balanced out. Imagine a cup with a hole in it being filled with water from a tap. The level of water in this cup would stay the same if the rate at which the water that flows inside is the same as the water that flows outside and thus, option C will be the correct answer."
"Equilibrium is defined as a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring. An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady."

Where is the moving electric field that causes Earth's magnetic field? A.)earth surface B.)in space C.)earth mantel D.)earth core
Answer:
D) core
Explanation:
The magnetic field is caused by the electric currents that occur in the core. The core is basically a hodgepodge of metals and really hot materials. Some of the metals, including iron and nickel, cycle around in the core in a process called convection. These convection currents lead to the electric currents and from there the magnetic currents.
Which of the following describes surface tension in water?

Answer:
C
Explanation:
Thisis the tendancy of the water surface to act as athin elastic stretched skin and can therefore support small objects when carefully placed on the surface
Surface tension allowing water to support small objects if they are placed carefully on its surface best describes it.
What is Surface tension?This is the property of liquid surfaces which makes a substance which has a higher density than water to float on the surface as a result of it being able to resist the external force.
Allowing water to support small objects if they are placed carefully on its surface without sinking is referred to as Surface tension.

Humans use many chemical substances for farming that consequently affect biodiversity. These compounds, which are rich in nitrogen and phosphorus, are used to fertilize crops. Excessive use of these compounds causes
Answer:
algal growth due to eutrophication
Explaination:
Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.

Some orders of land and marine mammals are closely related. Molecular data recently collected from dolphins, camels, deep and hippos have shown that hippos are the closest living relatives of dolphins. Which cladogram models this evolutionary relationship? *
Answer:
Roots
Explanation:
It should be understood that the classroom models show the evolutionary relationship between two or more organism. And they make use of the roots, class and the nodes.
In this case of dolphins and hippo, the answer should be roots. This is because organisms are vertebrates.
It should be noted that vertebrates are animals with backbones.
Scientists have observed unusual "benefits" of parasites in other species. This observation has led to some scientific debate regarding whether some relationships that were once considered parasitic may, in fact, be more mutualistic. Does the article support the idea of the existence of a mutualistic relationship between tapeworms and brine shrimps? Explain your answer using evidence from the text.
Answer:
Explanation:
Mutualism is a type of relationship where the organism involved both benefit from the relationship. This so true of tapeworms and shrimp as the infection caused by tapeworm on the shrimp bring about longetivity of the shrimp because it help them to survive in water containing arsenic toxins. Tapeworm lives on it host the shrimp and shrimp also benefit from tapeworm through its infection.
Answer:
No, the article doesn’t support the idea of the existence of a mutualistic relationship between tapeworms and shrimps. The article explains that it’s to the parasite’s benefit to keep the host alive, which explains why it may offer some protective benefit to the organism. The tapeworm still causes harm to the shrimp. So, the tapeworm still fits the definition of a parasite.

Answer:
Bayesian mimicry
Explanation:
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil.
Answer:
Mimicry
Explanation:
Mimicry can described or explained as the process whereby one organism copy the action of others and do exactly the same as that copied organism.
This is usually done when the action copied from the organism is useful in escaping from predators or being seen by other organisms as a predator and allow it to have access to the available resources.
In this case, when other organism copy the bright coloration of that small poisonous organism to drive away other organism, it is called mimicry.
