Answer:
Adjust the light intensity until an image can be clearly seen. Change the microscope objective lens to the next highest power and repeat step 3. Once at the highest objective lens, you should see graduations that are equal to approximately 10 microns
Answer:
Osmosis
Explanation:
As mentioned in the question,Pacific sea horse is an organism that face the constant challenge of losing water to their saltier environment. So if the environment is saltier it means that water will be moved from the Pacific horse' body cells into the environment to balance the concentration of salts. This process will happen when water molecules will move down the concentration gradient through selectively permeable membrane's of horse's body. This causes the loss of water from the body of horse and maintaining the salt levels of outside environment. This is called the process of Osmosis.
Here water move from an hypotonic environment (with less salts) into a hypertonic environment (with more salts).
Hope it helps!
Answer:
1. All volcanic eruptions are explosive
False
2. Volcanoes change the Earths surface constantly
True
3. Magma forms in the mantle
True
4. Volcanos are randomly located across the earth surface
False
5. Many volcanoes exist under the oceans
True
6. Volcanoes are only found in our solar system
False
Explanation:
1. Volancoes can also have effusive eruptions.
2. Volcanoes constantly change the Earth's surface in many ways.
3. The upper part of the mantle is where magma is formed.
4. Volcanoes are <u>not</u> randomly distributed over the Earth's surface.
5. There are many volcanoes under the ocean. Some rise half a mile above sea level.
6. There are volcanoes on the moons of Jupiter, Saturn, and Neptune.
Answer:
Secondary succession is a process in which a given area is disturbed, being re-colonized by other organisms following this process.
Explanation:
Secondary succession steps:
1- An area suffers a disturbance (e.g., fire, flood, earthquake, etc).
2-The process of disturbance destroys the food chain by removing primary producers (e.g., plants)
3- The vegetation grows back (i.e., first grasses and after higher trees). This process is known as recolonization
The secondary succession can regenerate an ecosystem in less than 50 years after disturbance. The first species re-established during secondary succession are the animals capable of living in disturbed habitats.
Answer:
conduction
Explanation:
Since ectotherms lack the capacity to generate heat within their body, one of the mechanisms they use in generating heat from the environment in order to maintain constant body temperature is, <em>energy transfer by conduction</em>. Conduction occurs when a lizard lays directly onto a hot rock.
Heat from the sun is transferred to the rock by radiation as the rock absorb the heat energy. This heat that is radiated in the rock is then transferred to a lizard that lays on it through conduction, and as the lizard absorbs this heat from the rock, they become warm.
- Energy transfer by conduction is mainly achieved through direct contact, and this is one of the methods that ectotherms like lizard rely upon to maintain constant body temperature.
