In Morgan’s second experimental cross of fruit fly eye color ,In the F2 generation, he noticed a 3:1 ratio of red to white eyes (option C)

American geneticist Thomas Hunt Morgan once observed a male fruit fly through a hand lens and thought it didn't look quite right. This fly has white eyes instead of the wild-type Drosophila melanogaster's characteristically vivid red eyes. Morgan was particularly interested in the inheritance and distribution of features in developing organisms, and he pondered what had changed the normal pattern of this fly's eyes. Morgan decided to do a straightforward breeding analysis to learn more about white eyes because his fly lab at Columbia University (Figure 1) was already used to breeding Drosophila so that the researchers there could witness the transmission of genetic features across succeeding generations.

Heat and high pressure which are applied to an igneous rock eventually creates a metamorphic rock. Thus, the correct option is B.

Rock cycle are the group of changes which enables the sedimentary, igneous, and metamorphic rocks to transform themselves from one kind of rock to another kind of rock through processes such as melting, cooling, eroding, compacting, and deformation of the rock. Igneous rock is the primary rock which is formed through cooling of the magma from the volcano.

Metamorphic rocks are formed from some other type of rock, however they have been substantially changed from their original igneous, sedimentary, or other earlier metamorphic forms. Metamorphic rocks are formed when the different rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, through some combination of factors to get converted into metamorphic rock.

Therefore, the correct option is B.

For the rock cycle to take place, energy from the sun and heat from the Earth are both necessary, and they each contribute to the different geological processes that cause rocks to change shape through time.

The production, disintegration, and reformation of rocks throughout the course of geological time is referred to as the rock cycle. It encompasses the alteration of igneous, sedimentary, and metamorphic rocks through procedures like cooling, erosion, sedimentation, heating and pressure, melting, and recrystallization.

According to Tori, the sun's energy is essential for the rock cycle to occur. This is because many processes that cause rocks to alter form, such weathering and erosion, are powered by the sun's light. Rocks erode as a result of water evaporating due to the heat of the sun and falling as precipitation. The wind is generated by the sun's energy and can carry and deposit sediment, adding to the cycle.

Jessica claims that without the heat from the Earth, the cycle could not exist. This is due to the fact that the melting and solidification processes that are essential to the rock cycle are driven by the heat of the Earth. The heat of the Earth causes rocks to melt, creating magma that can then solidify to create igneous rocks. The heat also fuels metamorphism, a process in which rocks undergo heat and pressure transformations to take on new forms.

Answer: Look at or examine the Sun.

Explanation: Helioscope is a device that is used to observe the sun. The term "heliocentrism" refers to the idea that the sun is at the center of the solar system. The Greek god Helios is the personification of the sun in ancient Greek mythology. So, it is likely that a helioscope was used to look at or examine the sun, rather than measure the distance between planets, search the surface of the Moon or plot out a planet's orbital path.

Xylem is the plant vascular tissue made up of dead tubular cells called tracheid, and its main function is to carry water and minerals from roots to various parts of the plant.

Xylem along with phloem makes the transportation possible in plants. Xylem is made up of tracheid, vessels, xylem-parenchyma and xylem fibers. Xylem is responsible for the transport of water and minerals from the roots upwards to the leaves. It also acts as a support structure to hold the plant upright.

Xylem is made up of dead tubular cells called tracheid, which has no cytoplasm, and provide a tubular structure for xylem. The walls are rich in  lignin and is thick walled and provide structural support. The only living cell in the xylem is xylem parenchyma, which stores starch and fats.

A seasonal outbreak of influenza is an example of a B common-source outbreak.

A common-source outbreak refers to a situation in which a group of people are exposed to a single source of infection. This can be a contaminated food item, water supply, or in the case of influenza, a person infected with the virus. The infected person can spread the virus to others through coughing, sneezing, or direct contact, leading to a cluster of cases.

Point-source outbreaks, on the other hand, refer to outbreaks that occur as a result of exposure to a specific, identifiable source at a specific time and place, such as a contaminated food item or water supply.

Propagated outbreaks occur when an infection is transmitted from person to person, leading to ongoing transmission in the community. This is different from a common-source outbreak where the original source of the infection is identified and contained.

In conclusion, a seasonal outbreak of influenza is an example of a common-source outbreak as it is a cluster of cases resulting from exposure to a single infected person.

Explanation: Humans are vertebrates that belong to the Kingdom Animalia. Eukaryotes are organisms that possess a nucleus enclosed by the nuclear membrane.

A leaflike structure in liverworts that is thin and flat and lies next to the surface is Lobe.

Lobe liverworts are so named due to the prominent, rounded lobes that make up the majority of their thallus (body structure). The lobes are thin and flat, arranged in rows on the surface of the thallus, and their edges can be either smooth or toothed. Each lobe has a single, unbranched vein that runs through the center, and this vein provides the lobe with nutrients, moisture and a connection to the gametophyte.

The lobes also contain chloroplasts, which are responsible for photosynthesis. The lobes are adapted to absorb as much light as possible and are usually flat, but they can also be curled up or cupped inwards, which can help them capture more light. These unique structures help liverworts survive in their shady, moist habitats, and their presence makes liverworts a unique and fascinating group of plants.

Explanation: because the lactose sinks into it

Benedict's reagent does not typically react with lactose. Benedict's reagent is a solution of copper(II) sulfate that is used to test for reducing sugars, including glucose and fructose.

When a reducing sugar is present, the reagent will change color from blue to green, yellow, or brick-red, depending on the amount of sugar present. However, lactose is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. Lactose, however, is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. To determine the presence of lactose in a sample, a different test, such as the lactose tolerance test, must be performed. In this test, the patient drinks a solution containing lactose and then has their blood glucose levels measured at intervals to determine how well they can digest lactose.
