5 Clear Mark for Review Sacculina carcini is a barnacle that attaches to the underside of the green crab. The barnacle finds a hole in the green crab's exoskeleton, then uses microscopic hairs to feed on nutrients from the green crab's blood. The barnacle also lays its eggs in the green crab reproductive system, which sterilizes the green crab. Which term describes the role of S. carcini in this relationship?
Answer:
S. carcini is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly 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. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
The Host increases the fitness of the parasite speciesThe parasitic species decreases the fitness of the host.By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.

5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.
Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
What is Tectonic Plates?
Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.
The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.
Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.
Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

Guess why most leaves are wide and thin.
Answer:
Due to their broad surface areas, green leaves can absorb more sunlight at a given time, and due to the thinness of the leaves, the light energy can easily penetrate the leaf surface and be trapped by the chloroplasts. This makes photosynthesis efficient. Therefore, green leaves are thin and broad.

Even though the idea of recycling materials and using them in other ways seems like a good idea, why is the idea of using recycled tires at playgrounds a concern for some scientists?
edge2021
Answer:
The idea of using recycle tires at playgrounds is a concern for some scientists because they contain carcinogenic substances.
Explanation:
Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.

What might happen to the magma convection currents if there were no radiogenic heat produced in the core?
How would this affect life on Earth?
Plz help me
Answer:
If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.
Explanation:
The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.
Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.
The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.
The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.
Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.

Use your knowledge of amino acids for energy metabolism to select the term that best completes each description. Glucose cannot be made when amino acids are converted to_________ . In the TCA cycle, some amino acids enter directly and, therefore, can continue in the cycle to generate energy and_______ . When is available, the body can use and glycerol to make some non-essential amino acids.
Answer:
Acetyl CoA; glucose
Explanation:
Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.
When is genetic drift a major factor in evolution?
O A. When there is low gene flow
O B. When there is high selective pressure
O C. When there is sexual selection
O D. When there is female choice
Answer:look at pic
Explanation:
When there is high selective pressure is the major factor in evolution.
What is Genetic drift?Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Therefore, When there is high selective pressure is the major factor in evolution.
