5 0

Answer: There are eight types of terrestrial biomes - temperate grasslands, temperate forests, tropical rainforests, subtropical rainforests, savannas, subtropical deserts, chaparral, boreal forests and arctic tundra.

Explanation: A terrestrial biome can be defined as an area of land that have similar communities of plants and animals and also similar climate.

Temperate grasslands: The climate temperature varies from semi-arid to semi-humid. Vegetation consist of grass and/or shrubs. Example includes Eurasian steppes, north american prairies.

Temperate forests: It is second largest biome , which covers 25% of the world's forest area. Its is known for its seasons and leaf-shedding trees. For example the Valdivian and magellanic temperate forests.

Tropical rainforests: It occurs in the areas of tropical climate. There is no dry season. Average precipitation of the year is at least of 60 mm. For example Daintree rainforests, Congo rainforests.

Subtropical rainforests: It has the the features of temperate forests and tropical forests.

Savannas: It is a mixed woodland grassland ecosystem. Tress are widely spaced so that canopy does not close. For example Serengeti plains of Tanzania.

Subtropical desert: High temperature, warm soils, and very low precipitation are its important features. Plants such as shrubs and succulents can be found there. Mojave desert, Sonoran are the examples.

Chaparral: It is a heathland plant community. Found mainly in US state of California and in northern portion of the Baja California peninsula. For example Santa ynez mountains, near Santa Barbara, California.

Boreal forests: It is also known as Taiga. It has coniferous forests consisting mainly of spruces, larches and pines. It is world's largest forest. For example Jack London Lake in Russia.

Arctic tundra: It is a vast, cold, and treeless area of low, swampy plains in the north around Arctic ocean. There are three regions and associated type of tundra that are Arctic, Antarctic and Alpine.

Describe some ways abiotic factors you would most likely see in a local meadow or pond

Citrus2011 [14]

Before answering this question, we need to undersand what is the meaning of abiotic factors, the abiotic factors are basically non living factors that exist in our environment for example water, mountains, ponds etc.

If we visit a local meadow or pond, the possible abiotic factors we can see there are water, sediments, Stones, Wind, Atmosphere, light (Sunlight falling on leaves or plants, Soil and moisture lying on land.

Hope it helps! :)

TRUE

Mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer).

How do secondary consumers help the ecosystem? Please help ASAP

miv72 [106K]

Answer:

First off, we need to establish what secondary consumers are. Primary consumers are all herbivores; they eat the producers. The secondary consumers are on the next trophic level up; they eat the primary consumers. They thus help to control the level/number of primary consumers; otherwise, the number of primary consumers would grow too high, and the producers would all be WIPED OUT.

Now, you may be wondering what controls the amount of secondary consumers? The answer is tertiary consumers. What controls the tertiary consumers? At this point, energy does the job of limiting the population. As you move up trophic levels in an ecosystem, the amount of energy in each trophic level goes down by 90%. So like if you started w/ 1000000 joules of energy in the producer level, that would be 100000 in the primary, 10000 in the secondary, and only 1000 in the tertiary.

Suppose a one-year old child is playing with a toy near an electrical out-let. He sticks part of the toy into the outlet. He get

Papessa [141]

Answer:

UCS: sticks part of the toy into the electrical outlet

UCR: frightened and crying

CS: toy

CR: frightened to toy

Explanation:

Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

Unconditioned stimulus (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.

Unconditioned response (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.

Conditioned stimulus (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

Conditioned response (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.

You do know that you have to give a topic on what this project is about, also doing this quick is never gonna happen. Science projects take TIME AND EFFORT. So, with that being said, sorry for wasting your time.
