As you move to a higher elevation (e.g. in the mountains), the air pressure drops significantly. In turn...
the temperature of water increases and the density goes up as well.
the temperature of water drops and the density of it goes down as well.
the evaporation rate of water increases at all temperatures causing an increase in volume.
the evaporation rate of water decreases at all temperatures causing a decrease in volume.
Answer:
the temperature of water drops and the density of it goes down as well.
Explanation:
The higher the altitudes, the lower the temperature.
At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.

The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove
The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove.
What is euglena ?
It is the alga that has the ciliates and flagella also to obtain the movement .
The paramecium uses cilia to sweep food into its oral groove Paramecium are heterotrophs and have to devour meals. The location of the paramecium that looks pinched inward is referred to as the oral groove. Cilia sweep meals into this location. Food enters the paramecium via the oral groove (mouth pore) and is going to the gullet (shadeation the oral groove and gullet mild brown).Euglenas create their personal meals via photosynthesis, the manner of soaking up daylight to synthesize meals from carbon dioxide and water. An eyespot on the the front stop of the euglena detects mild, and its chloroplasts (systems that include chlorophyll) lure the daylight, permitting photosynthesis to occur.\Read more about chloroplasts refer link :

A plant seed is formed from:
a fertilized egg
growth of an egg
growth of a spore
a mature pollen
Answer:
D. a mature pollen
Explanation:
Answer:A plant seed is formed from a fertilized egg.
What is a seed?A seed is an embryonic plant enclosed in a protective outer covering. The formation of seed begins with fertilization, which occurs when the pollen from the male reproductive organ (stamen) fuses with the female reproductive organ (pistil). The fertilized ovule develops into a seed that contains the embryonic plant and a supply of nutrients to support its initial growth until it can begin photosynthesis. The seed coat is the outer covering that protects the embryo from desiccation, disease, and physical damage.

Read the following excerpt and answer the question:
Emilie Dressaire, professor at Trinity College (Hartford, CT), and her colleague Marcus Roper (UCLA) discovered that mushrooms create their own microclimates. They create their own moisture through evaporation, which is when a liquid turns into a gas. Heat energy is used in this process, leaving the mushrooms cool and moist.
Use your own words to summarize the effect of thermal energy on a mushroom's environment and how this sustains life. (4 points)
Answer:
Mushrooms can reproduce by using thermal energy to create conventional currents, which are known as pockets. Following the formation of the pockets, the currents disperse microscopic spores in the surrounding air. As a result of the spread, a large spore cloud forms, which is visible at night.

Describe the amphibian life cycle. Include the different phases and traits of each phase.
Answer:
Another Brainly Answer
Explanation:
The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs, but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed by using something called apoptosis. Then it's pretty much and adult frog.

Memories of a Memory
Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.
First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."
Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.
Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.
With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.

Why do you think the western gorilla’s hands are shaped the way they are? What does the western gorilla use its hands to do?
why do you think the European mole’s hands are shaped the way they are? What does the European mole use its hands to do?
Explanation:
Gorilla: This is very hard to think about but to like help support the the gorillas body when it's like doing that with its hands
Mole: The way there hands are built, it can easily claw it's way through the ground and get places easier.
Both the animals hands might be shaped the way they are due to the required adaptation for their own environment as it differs from place to place. The gorilla may use their hands to have a faster way of transportation as they move to foraging.
What is foraging?Foraging is a behavior which includes all the methods by which an animal acquires and utilizes sources of energy and nutrients. This also includes the location and resources consumption, as well as their recapture and storage, within the context of the larger community.
The european mole's hands are in that shaped due to the need of survival and to build their shelter. The european mole may use their hands to dig to provide themselves a safe shelter and to hide from predators.
