Hormones released by the _______ system regulate the amount of urine produced by the ___________ system
Furkat [3]

<u>endocrine</u> and <u>excretory</u>

<u />

Different glands in the endocrine system (ex: the adrenal gland) produce hormones (ex: epinephrine/adrenaline) that circulate throughout the blood to regulate various cellular processes in various areas of the body.

The excretory system is responsible for the excretion of wastes from the body. This body system includes several organs from other body systems. For instance, the lungs are technically a part of this organ system (along with the respiratory system) because the lungs remove CO2 (a metabolic waste product from cellular respiration) from the blood and out of the body when you breathe out. Another, probably even more obvious example, of organs involved in the excretory system are the kidneys, bladder...etc (i.e. urinary system).

Write a summary where you give the name of the biome you live in.do reaserch on your biome and discuss the type of plants,animal
tresset_1 [31]

Biomes are very large ecological areas on the earth’s surface, with fauna and flora (animals and plants) adapting to their environment. Biomes are often defined by abiotic factors such as climate, relief, geology, soils and vegetation. A biome<span> is NOT an ecosystem, although in a way it can look like a massive ecosystem. If you take a closer look, you will notice that plants or animals in any of the biomes have special adaptations that make it possible for them to exist in that area. You may find many units of ecosystems within one biome. 

There are five major categories of biomes on earth. In these five, there are many sub-biomes, under which are many more well defined ecosystems.

</span>

<span>The Desert Biom - Deserts makeup about 20% of total land cover on earth and are characterized by little (less than 50cm/yr) or no rainfall. Desert biomes come in four major kinds— each of these having their unique features but have similarities in their biotic and abiotic makeup. They are the Hot and Dry Deserts, Semi Arid Deserts, Coastal Deserts and Cold Deserts, and within these are many deserts located in many places of the world.</span>

The Aquatic Biome<span> - This includes all water bodies on the earth’s surface. Aquatic biomes are grouped into two, Freshwater Biomes (lakes and ponds, rivers and streams, wetlands) and Marine Biomes (oceans, coral reefs and estuaries). These biomes make up about 73% of the total 
earth’s surface.</span>

 

The Forest Biome<span> - Forests makeup about 30% of the total land cover on earth and are of incredible value to life on earth. They are a store of carbon and play a very important role in climate control. They have a watershed role and are a source of many raw materials that humans depend on. </span>

The Grassland Biomes:<span> <span>There are two main types of grassland biomes: the Savanna Grasslands and the Temperate Grasslands. </span></span>

The Tundra Biomes:<span> <span>There are two major tundra biomes—The Artic Tundra and the Alpine Tundra. </span></span>
