Temperate Forest
Temperate forests are those found in the moderate climates between the tropics and boreal regions in both the Northern and Southern Hemisphere. They may also be called “four-season forests” because the midlatitude climates harboring them tend to experience four distinct seasons. A vast diversity of different forest types make up this broad category, from the broadly distributed temperate deciduous forests to pine woods and relatively geographically restricted temperate rainforests.
Temperate forest often refers specifically to the temperate deciduous forests widespread in eastern North America and Eurasia, but other temperate-forest types exist in the planet's middle latitudes where moderate, frequently four-season climates encourage diverse tree growth.
Locations and Climates
Temperate forests range across large areas of North America and Eurasia as well as smaller portions of the Southern Hemisphere. Temperate deciduous forests, the “signature” temperate forest type, reach their greatest extent in the eastern United States and Canada, Europe, China, Japan and western Russia. Climatically speaking, temperate forests tend to experience fairly long growing seasons and decent amounts of rainfall that may be spread fairly evenly across the year or concentrated in a particular season; deciduous hardwoods, which lose their leaves in winter, dominate most major temperate forests. Drier temperate climates in, for example, western North America may see evergreen pines and other drought-tolerant conifers proliferate. Temperate rainforests, two-thirds of which lie in North America’s Pacific Northwest, experience milder, moister, often maritime-influenced climates than other temperate forests; those of the Pacific Northwest are unique in the dominance of conifers over hardwoods.
Seasons in a Temperate Deciduous Forest
During the winter, a temperate deciduous forest looks dead because leaves have fallen off most of the trees. Wildlife in these forests may endure the winter or migrate to warmer climates. Spring sees a rebirth of sorts with hardwoods leafing out and a proliferation of flowering shrubs and forbs. As days begin shortening and temperatures dropping in fall, the leaves of deciduous trees change color and begin dropping, while animals begin storing food for the winter and/or packing on body fat for winter survival or the energetic demands of migration.
The Flora of Temperate Forests
The soils of many temperate forests are fertile and support a rich diversity of trees. Temperate deciduous forests often feature varieties such as maples, oaks, elms and birches. Conifers such as pines and hemlocks may play a minority role in these hardwood-dominated communities, but, again, these needle-leaved trees may also form the majority in certain temperate ecosystems, such as the North American temperate rainforest and the pine forests of the southeastern U.S. A sub-variety of temperate forest found in so-called Mediterranean climates commonly features evergreen broadleaf trees, such as “live oaks” in California and parts of Southern Europe and eucalpts in Australia. Mosses, ferns and understory shrubs are common in many temperate forests.
The Fauna of Temperate Forests
With their moderate climate and typically rich array of food resources, temperate forests tend to support a great diversity of wildlife. Koalas, possums, wombats and other marsupials roam Australian temperate forests, while in North American and Eurasian ecosystems deer, bears, foxes, wolves, squirrels and rabbits are common inhabitants. China’s temperate forests play host to giant and red pandas, which mostly eat bamboo. Many migratory songbirds nest in temperate forests, taking advantage of their spring and summer bounty of blossoms, berries, seeds and insects.

Jean-Paul is racing in the Tour de France bicycle race. He is moving along rapidly at a speed of 15 kilometers per hour. Suddenly, a strong wind begins to blow into his face. Jean-Paul cannot exert any more force on the pedals. What will happen to Jean-Paul's speed while the wind continues to blow against him?
If the air resist his motion continuously, speed of Jean - Paul get reduced until he could apply an equal force in opposite direction to the wind.
What is force?Force is an external agent acting on an object to change its state of motion or rest or to deform it. There are various kinds of force such as gravitational force, magnetic force, frictional force.
If there are two different forces acting from the same direction will add up together and the net force will be the sum of their magnitudes. If they are in opposite direction, they will balance each other will decreases the displacement.
Hence, the force from the air resistance will balance the force exerted by Jean Paul and his speed will decrease until he apply a greater force forwards.

What do different kinds of transformers do?
Answer:
There are three primary types of voltage transformers (VT):
Electromagnetic
Capacitor
Optical.
Explanation:
A capacitor voltage transformer (CVT), also known as capacitor-coupled voltage transformer (CCVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal, for metering or operating a protective relay.
Optical Current Transformers and Optical Voltage Transformers, based on the Faraday and Pockels effect, are a new family of instrument transformers and an alternative to the conventional electric-magnetic transformers for protection and metering purposes.
An electromagnetic voltage transformer is a voltage transformer that converts a primary voltage into a secondary voltage by electromagnetic induction. This transformer does not add other electrical components such as capacitors that change the primary voltage.

Explain: In dominant/recessive inheritance patterns, the dominant allele is always expressed when present. The recessive allele is only expressed when the dominant allele is not present. Use your observations from this activity to describe how codominant inheritance patterns differ from dominant/recessive inheritance patterns.
Answer:
Codominance refers to a type of inheritance in which both alleles of a particular gene are expressed in the phenotype. In other words, no allele is completely dominant over the other. This differs from dominant/recessive inheritance patterns, in which only one copy of a dominant allele needs to be present to express the phenotype, and two copies of the recessive allele are required in order to express the recessive phenotype.
2) I'm not sure exactly what answer you are looking for here, but an example of codominance is individuals with blood type AB. In this case, the offspring inherits the A allele from one parent, and the B allele from the other parent. Such individuals express both A and B antigens on the surface of their red blood cells, making them phenotypically blood type AB.

1.How is this star system different from our solar system?
2. what do you think would be different if you were on a planet in this star system?
Answer: 1. While stars do move, they move in a differently in comparison to the planets in our solar system. Stars move in a circular pattern around the North Star, therefore, if the light that you see appears to move in a straight line over a few nights, it is most likely a planet.
2. The resources are very different, the temperatures, and some don't even have water or are unable to grow crops
Explanation:
A star system is a collection of planets, meteors, or other objects that revolve around a large star. While our galaxy contains many star systems, including at least 200 billion other stars, there is only one solar system. This is due to the fact that our sun is known by its Latin name, Sol.
What is solar system ?The solar system is made up of the Sun and everything that orbits or travels around it. This includes the eight planets and their moons, as well as dwarf planets, asteroids, comets, and other small, icy objects. Despite this, the majority of the solar system is empty space.
Earth has distinct characteristics that have resulted in life flourishing on the planet. Its distance from the Sun, 24-hour rotation period, radius, and availability of water on the surface distinguish it.
A star is a body that has a light that causes it to reflect light on its own. A planet, on the other hand, is simply a fixed celestial body that has its own orbit and spins on its own axis while reflecting light from an external source.
Thus,While our galaxy contains many star systems, including at least 200 billion other stars, there is only one solar system.
