How did the volcano on the land
Form?

Answers

Due to the shifting of the plutonic plates in the ground volcanos starting forming.

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.

could lessen the damage of potential earthquakes? (Describe at least two.)
4. What are some costs and benefits of one of your proposed solutions?

Answers

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.

What is Earthquake?

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.

What evidence have you discovered to explain how cells are organized in the body, similar to the way dots in pointillism art is organized.

Answers

Answer:

I'd have to say that cells are grouped by function and specialty. Many of the same type of cell are joined in a common task. Muscle cells are joined to form a specific task. Different cells in the body form into different organs and structures to form the whole body.

In art, pointillism uses dots of various sizes and colors. These dots are arranged so as to produce a specific visual effect. The entire work is composed of many individual points to form the whole picture.

In this way, we can equate the body's various cell to dots in a work of pointillism.

what is the difference between fraternal twins and identical twins in terms of gene reproduction?

Answers

Answer:

Fraternal twins are dizygotic and Identical twins are monozygotic.

Explanation:

Fraternal twins are dizygotic, meaning that they developed from two different eggs fertilized by two different sperms. Their genetic code is as similar (or dissimilar) as any other siblings. Identical twins are monozygotic, meaning that they developed from the same fertilized egg, and so have nearly identical genetic code.

Identical twins are monozygotic while fraternal twins are dizygotic

a two-paragraph report on flower reproduction

Answers

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.

Answers

b i think ??
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.

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.

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?

Answers

It is a Protista, but if you want to be more specific then it’s a paramecium caudatum. Please put me brainlest please.

Protista 

Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.
