In tomato plants, red fruit (R) is dominant to yellow fruit (r). Interpret the Punnett square below, which shows a cross between a heterozygous red plant and a yellow plant. Include the possible genotypes and corresponding phenotypes.
Answers
Answer:
2/4 or 50% are red-fruited (Rr) and 2/4 are 50% are yellow-fruited (rr)
Explanation:
brainliest pls
Dominant traits are the allele that is expressed in purebred and heterozygous condition. 50% of progenies are red and the other 50 % are yellow.
What is a Punnett square?A Punnett square is a diagrammatical representation of the cross between the parents that portrays the alleles in the square boxes. It is used to conclude about the genotype and the phenotype.
From the Punnett square, it can be concluded that:
The phenotype and the genotype of the offspring, red: yellow = 1:1
Therefore, the red plants and yellow plants are in a ratio of 1:1.

Answer:
Underwater volcanoes form much like volcanoes on dry land by a process known as subduction.
Explanation:
This occurs as a result of tectonic plates which form the top layer of the Earth's mantle, just below the Earth's crust. They support the weight of the continents and the combined water of the seas.

Explanation:
The yellow pea is dominant so if it is crossed with a pure recessive then they will all be yellow
According to Punnett Square, if mating produces 100 offspring, then all of them will have yellow seeds. Thus, the correct option for this question is D.
What is the Punnett Square?The Punnett Square may be characterized as a kind of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are systematically demonstrated.
According to the question, there is a homozygous dominant genotype of one parent when crossed with the heterozygous genotype of other parents, then the genotypes of resultant offspring must carry at least one dominant allele which governs the phenotype of the entire offspring.
Therefore, according to Punnett Square, if mating produces 100 offspring, then all of them will have yellow seeds. Thus, the correct option for this question is D.

Read the passage. Then write a paragraph that explains why the two ecosystems have such different kinds of plants. Use the terms biotic factor, abiotic factor, and limiting factor in your explanation.
Passage
A group of students is studying the types of plants that grow in a field next to the school. The field is mowed regularly, but it does not get any water other than rainfall. The field has several kinds of plants that are typically found in a grassland ecosystem. But it has none of the plants found in a nearby forest ecosystem.
Answers
Answer:
The reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, some biotic factors like animals or humans could be the reason. The humans may have planted seeds there, and probably some abiotic things like soil could also be the reason why. The plants that grow there receive a lot of rain, or the limiting factor is the rain, and the type of plants that grow there don't need much water to survive.

Answers
sorry if wrong
According to the diagrams. the following statements which is true is the upper part of the Venus' troposphere is about 200°C colder than the upper part of the Earth's atmosphere. Thus, the correct option is B.
What is the relation between troposphere and temperature?As the elevation increases, there is less air above us thus the pressure keeps on decreasing. As the pressure decreases, air molecules spread out further and expand in air, and the temperature of the atmosphere decreases.
Temperature of the atmosphere decreases with the increase in altitude because the troposphere is warmed from below, through the absorption and re-emission of incoming solar radiation by the Earth's surface, rather than it is being warmed from above through the incoming solar radiation.
According to the given diagram, the statement which is true is that the upper part of Venus' troposphere is about 200°C colder than the upper part of Earth's.
Therefore, the correct option is B.

How does the ocean interact with land and air?
Answers
Answer:
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
