Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.

During which phase does Earth see more than half of the moon's surface?
3) Waxing gibbous
In waxing gibbous phase Earth see more than half of the moon's surface
What is waxing gibbous?The Waxing Gibbous phase occurs when the illuminated portion of the Moon increases from 50,1% to 99,9%. Up till the Full Moon, it lasts from the time right after the First Quarter Moon. Gibbous refers to the oval to circular form, whilst waxing denotes that it is growing in size. It might be difficult to distinguish the Waxing Gibbous Moon from a Full Moon as its lighted portion increases to 98–99 percent.
The Waxing Gibbous Symbolizing the last actions you must do to complete your task or complete the job. It's the moment when you can finally make out the light at the end of the tunnel, and it's also the time to push yourself to the limit and finish what you've begun before the Full Moon so you may bask in the glory of your passion project.
You may feel the impulse to refocus your life or a project during the Waxing Gibbous Moon. It's crucial to not battle this emotions. Only positive things will occur if you embrace it and trust it rather than resist it. It's likely that some sacrifices may be needed to reap the revaluation.

what is an allele????
Answer:
The short answer is that an allele is a variant form of a gene.
Explanation:
Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.
PLEASE GIVE ME BRAINIEST
An allele is one of multiple forms of a gene that exists at the same location on a chromosome and is responsible for the variety observed in the traits of organisms. Alleles can give rise to different phenotypes, which depend on their combination in the genotype of an individual. The expression of alleles can follow different patterns like incomplete dominance or codominance.
An allele is one of two or more alternative forms of a gene that arises by mutation and are found at the same place on a chromosome. Alleles can lead to different phenotypes, or observable traits, in an organism. For instance, a gene that determines flower color in a plant might have two alleles, one resulting in red flowers and the other resulting in white flowers. The combination of alleles that an organism has, known as its genotype, directly impacts its phenotype. Different patterns, such as incomplete dominance or codominance, can influence the outcome of an organism's phenotype when two different alleles are present.
In cases of incomplete dominance, the phenotype of the heterozygous genotype (where two different alleles are present, such as Aa) is often intermediate between the phenotypes of the homozygous genotypes (where two of the same alleles are present, such as AA or aa). Codominance is a condition where both alleles of a gene pair in a heterozygote are fully expressed. For instance, the AB blood type in humans is a result of codominance, where both A and B alleles are expressed.

Parasitism could be considered a form of which of these types of relationships?
-Mutualism
-Commensalism
-Predator-Prey
-Mimicry
Answer:
I think Commensalims just tell me if I am wrong
Answer:
The correct answer is option - predator-prey.
Explanation:
Parasitism is the relationship between two different organisms in which one is the host and the other called parasite. The host is the one who gets harm by the parasite, whereas parasite takes it food and nutrition from the host and get benefited.
Parasitism and predator-prey relationship are similar to the one get benefited and other loose life or get harm in such a relationship.
Thus, the correct answer is option - predator-prey.

Convection currents transfer thermal energy ___? A. Between continents B. From cooler regions to warmer regions C. From warmer to cooler regions D. As a result of buoyancy
Hello There!
"Option C"
Convection currents transfer heat from warmer regions to cooler regions
Convection currents transfer heat from one place to another.
Convection currents transfer thermal energy from warmer to cooler region.
Option C
Explanation:
Thermal energy is transferred by convection from hot places to cold places. It is form of "kinetic energy" that is transferred as heat. When the hot liquid or gas becomes cool liquid or gas then convection happens. Then the cooler gas or liquid will goes to the place of hotter gas or liquid. This results in a "continuous circulation sequence".
"Water boiling" in a beaker is one of good examples of these "convection currents". Atmosphere is also example of convection. The Earth surface gets heat by sun the warm or hot air rises and cool air moves in. Other options are incorrect as thermal energy transfers from warm to cool places by convection.

Which structure is the site of photosynthesis within a plant? A. Roots B. Stomata C. Xylem D. Leaves
Answer:
The site of photosynthesis of a plant a.k.a kitchen of a plant is the leaf.
Explanation:
The leaf is the site of photosynthesis because its broad surface can absorb sunlight. Chloroplast is present in leaves, which contains chlorophyll which is a key factor of photosynthesis. The leaf has stomata under its surface which is responsible for gaseous exchange. Therefore, leaves act as the primary location for photosynthesis.
Hope this helps <3
Final answer:
Leaves are the major site of photosynthesis in plants, specifically within a layer called the mesophyll, and gas exchange occurs through regulated openings known as stomata.
Explanation:
The major site of photosynthesis in plants is the leaves. Photosynthesis occurs in a middle layer of the leaf called the mesophyll, where cells contain chlorophyll, the green pigment crucial for this process. The gas exchange of carbon dioxide and oxygen essential for photosynthesis takes place through the stomata, which are regulated openings typically found on the underside of the leaf. These stomata are controlled by guard cells that respond to osmotic changes to regulate the loss of water and the intake of carbon dioxide.
Photosynthesis is the process in which green plants, algae and some bacteria convert light energy from the sun into chemical energy in the form of glucose (a type of sugar) and oxygen. This process takes place in the chloroplasts which are located in the leaves of a plant. The chloroplasts contain chlorophyll, a green pigment that captures light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen during photosynthesis. Therefore, the correct option is D. Leaves.
what r some adaptions that help animals who live in the Alpine biome survive
Animals in the Alpine biome have adapted to survive temperature fluctuations through migration, like the Arctic Tern, Monarch butterflies, and Reindeer. Others, like the Snow Leopard and Cheetah, have physical adaptations such as thick fur and fast speed. Still others use behavioral adaptations like mimicry and camouflage.
Explanation:Animals living in the Alpine biome have developed several interesting survival adaptations. Temperature fluctuations are a major challenge they face which many of them have adapted to by adopting a strategy of migration. For example, the Arctic Tern makes a 40,000 km round-trip flight each year between both hemispheres to find food and suitable breeding grounds while Monarch butterflies and Reindeer also migrate significant distances for similar reasons.
Some other kinds of adaptations include physical changes to their body. For instance, the thick fur of Snow Leopards is an adaptation for surviving in cold conditions and a Cheetah's fast speed helps it catch prey effectively. Besides these, there are also behavioral adaptations like mimicry and camouflage which animals employ for survival.
However, not all animals migrate because of the risks and high energy costs associated with migration. Also, some classes of animals like amphibians and reptiles are more limited in their distribution because they generally lack migratory ability.

Explanation:
Why would a rough steep mountain habitat have a higher rate of speciation than a large open grasslands habitat?
A rough steep mountain habitat will have a higher rate of speciation than a large open grassland. The reason for that is that the open grassland has monotonous living conditions all through it, thus the species are the same with the same adaptations all over it. The rough steep mountain habitat, on the other hand, has multiple different living conditions. The different living conditions are defined by the elevation, and in accordance to it there will different species living at different elevations. Also, the mountain is a natural barrier for the air masses, so while on one side of it there's rainfall, on the other one there's dry weather conditions, which again creates different living conditions, different adaptations by the living organisms, thus different species.
Answer:
The mountains prevent organisms from interacting.

Upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water.
Upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
Answer:
Upwelling improves the nutrient supply at coastal fisheries as the cold, nutrient-rich water replaces the warm, nutrient-poor surface water
Explanation:
The upwelling is simply the process through which the cold water rises up toward the surface, pushes and moves away the warmer water, until it gets warmer and is pushed by the colder water blow it. The cold water that rises toward the surface is nutrient-rich, while the warm surface water is nutrient-poor. By having the nutrient-rich cold water come toward the surface, the coastal fisheries have great benefit, as the more nutrients there are, the more fish there will be for them to catch.
