Ok so basically this seems more complicated than it is

We want to start with coming up with three traits say your "living thing" will have...

let's use some simple traits that we know and have seen in other animals

(I'm using a cat-like animal in reference)

Ear size: Large, Small

Fur color: Grey, Black, Grey with Black, Black with Grey

Now let's take a look at the chart

Hope This is Helpful!

Discuss how the properties of water help Earth support life.

s2008m [1.1K]

Answer:

Explanation:

Water's extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water's role as a solvent helps cells transport and use substances like oxygen or nutrients

azamat

Answer:

In multicellular organisms, the mechanism most directly responsible for directing development and maintaining homeostasis is gene "regulation"

Explanation:

Even though the organs present throughout the body helps in maintaining the homeostasis, But the systems like endocrine system and nervous system plays important role in sustaining and regulating it. The gene regulation is the increase and decrease of the specific gene products. Gene regulation can also be understood as the regulating process which helps in controlling ability of the cell to the environmental changes or can say the adaptability of the cell to changing environment done by gene regulation.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is

blsea [12.9K]

Answer:

Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:

osmosis - water molecules readily pass through the membrane; the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradient
facilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.

Name two ways water travels from land to enter the ocean

Kitty [74]

Answer:

Seepage; runoff

Explanation:

In nature, water is constantly circling: from the water surfaces it evaporates, travels up in the atmosphere, there it condensates, forms clouds, and then again falls to the land and water surfaces. This cycle has been going on for thousands and thousands of years and is known as the water cycle.

Now, the real question is how does the water, fallen from the clouds, on the land, travel back to the oceans.

Soil consists of multiple layers, some are water permeable, and some are not. When water (rain) reaches the soil, through tiny pores in upper permeable layers it will travel downward, deeper and deeper. This process is called the seepage. Upon reaching the water-impermeable layers, it stops, becoming part of what is known the underground water. It will continue to flow on this layer until it finds its way back on the surface, usually in a form of a spring, which will find its way to a river, and river will take that water to a sea or an ocean.

However, if the soil is to saturated with water, especially during long rainy, stormy period, or in the spring, after the snow melts. This excess water will, because of the gravity, flow over the earth's surface, from higher (mountains) to lower (valley) areas, making its way to some valley river, which will take it further to a sea or an ocean.

Upon reaching the ocean, this land-water can again join the water cycle, again and again.
