Answer:

it depends where the the muscle is located and what is the purpose

Explanation:

Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.

Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.

Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.

Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.

Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

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.

There are about 50 Orange-bellied Parrots remaining in the wild and a captive breeding population of around 320 individuals. The species is at risk of extinction in the wild in the near term. Current expertise suggests that habitat loss and degradation, particularly in the non-breeding range, has caused the decline.

Hi!!

So Rosa eats a peanut butter sandwich, which gives her protein and starch, right? She also goes on a run and breathes normally, which gives her a good amount of oxygen. Based on this, we can conclude...

1. Cells need the protein and starch to make energy.

A cell uses proteins to keep itself alive and functioning. Because the proteins keep the cell working, the cell can change the starch into sugars, which in turn becomes food for the cells. The sugar is used to keep Rosa running.

2. The cell also needs oxygen.

The cell gets oxygen through the bloodstream. When Rosa breathes well, she is making sure that she is providing her body with enough oxygen to run.

Rosa's body systems give the cells protein, starch, and oxygen, which allows the cells to function. This, in turn, allows Rosa to run and play without worry.

The main limiting factor for the plants and animals that live in the deciduous biome is cold temperatures in winter.

Flora and Fauna living in the Deciduous Forest Biome must be able to adjust to warm and relatively hot summers and cold to freezing winters. They are also required to adapt to the four distinct seasons of this biome. There are also large amounts of rainfall and fertile soils in this biome.

Thus, cold temperatures in winter are the correct option.

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.

The abiotic factors that are present in the image are the light from the sun, the air, the mountain, the water, etc., as abiotic substances, also known as abiotic factors, are non-living components of an ecosystem.

Abiotic substances include physical and chemical factors that affect the ecosystem, such as water, air, light, temperature, soil, nutrients, minerals, etc, where as water is an abiotic substance and is essential for many cellular processes and regulating body temperature, light is necessary for photosynthesis, which is the process that allows plants to produce energy from sunlight, and temperature is important because it affects the metabolic rate of organisms, and extreme temperatures can cause stress or even death.

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:

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.

I would modify seismograph resources by requesting reports from earthquake stations that felt the tremors.  I would then use the reports and look at the arrival time of the p waves and the s waves.  If a station recorded the s waves arriving much quicker than the others, I can safely say that the epicenter was in that area.  From there, I can request reports in that area and use the triangulation method to pinpoint the exact location.
