Answer:

D

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.

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.

Answer:

On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate subducts, or moves under, a thicker continental plate. When this happens, the ocean plate sinks into the mantle. Water trapped in the rocks in this plate gets squeezed out.

Explanation:

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.

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.

Answer:

Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. ... Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant. The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Explanation:

Answer:

      Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase. The life cycle of a flowering plant. The angiosperms were the last of the seed plant groups to evolve, appearing over 100 million years ago during the middle of the Age of Dinosaurs. Reproductive parts of the flower are the stamen and carpel. Often the carpel is referred to as the pistil, the female parts collectively termed the gynoecium. The androecium is the individual units of the androecium are the stamens, which consist of a filament that supports the anther.

     Pollen Pollen grains, from the greek palynos for dust or pollen, contains the male gametophyte phase of the plant. The outer part of the pollen is the exine, which is composed of a complex polysaccharide, sporopollenin. Hypothesized steps in the evolution of the carpel. Nonvascular plants, the mosses, and liverworts have the gametophyte phase dominant. Vascular plants show a progression of increasing sporophyte dominance from the ferns and "fern allies" to angiosperms.

Answer: The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.

Explanation:

1) Manifest Destiny: The US Government wanted settlers to move onto the Plains as they needed the land to be settled and farmed and for communities and towns to grow up and expand. This was needed if the USA was to be a rich and successful country. The government therefore promoted the idea of Manifest Destiny.

Answer:

earthquakes are monitored worldwide because we never know when they will occur, they can happen everywhere in the world even in the areas that are far away from the tectontic plates boundaries. that is why earthquakes are monitored worldwide instead of in earthquake-prone areas only.

Answer:

1. Why are earthquakes monitored worldwide instead of in earthquake-prone areas only?

Earthquakes are monitored worldwide instead of just earthquake-prone areas since earthquakes can happen all over the world, even far away from plate boundaries.

2. How many seismographs are needed to find the epicenter of an earthquake? Why is this number significant?  

You need at least three seismographs to find the epicenter of an earthquake. The reason you need three or more seismographs is so you can see where the waves overlap to find the epicenter.

The proposed solutions that could lessen the damage of potential earthquakes are establishing the ledge barrier on shelves, always anchoring the large appliances to walls employing protection cables or straps.

An earthquake may be defined as an impulsive violent trembling of the ground, generally causing tremendous devastation, as an outcome of motions within the earth's crust or volcanic action.

The costs of proposed solutions are a little bit expensive, while it results in the benefit to save and escape your life from earthquake activity to a larger extent.
