which kind of soil is likely to have the HIGHEST porosity? A) Soil that is a mixture of sand and clay. B) soil that is all clay. C) soil that is a mixture of silt and clay. D) soil that is all sand.
Answers
Explanation:
Sand have the largest particle size so it has the highest porosity.
The answer is Soil that is all sand (D).
Soil that is all sand is likely to have the HIGHEST porosity. Therefore option D is correct.
Porosity refers to the amount of empty space or voids within a soil or rock. It is a measure of how much water or air can be stored in the soil. The type and arrangement of soil particles greatly influence porosity.
Sand particles are relatively large and have larger spaces between them compared to clay or silt particles. This means that sand has a higher porosity because it has more empty spaces or voids that can hold water and air.
The larger particle size allows for better drainage and easier movement of water and air through the soil.
In contrast, clay particles are much smaller and tightly packed together, resulting in smaller spaces between them. This compact arrangement reduces the porosity of clay soils, making it harder for water and air to penetrate and move through the soil.
Soil that is a mixture of sand and clay may have a moderate porosity, as the sand particles contribute to higher porosity while the clay particles reduce it to some extent. Similarly, soil that is a mixture of silt and clay may also have moderate porosity.
Therefore, if we consider the given options, soil that is all sand is likely to have the highest porosity due to the larger particle size and the resulting larger spaces or voids between the sand particles.

explain the difference between gills and lungs. Give examples of animals that have only gills, animals that have only lungs, and animals that have both gills and lungs. What are the advantages of having gills, having lungs, and having both?
Answers
Answer:
Gills and lungs differentiate in many ways most certainly when it comes to breathing. Gills are used by aquatic animals such as; sharks, fish and octopi. Lungs on the other hand are mainly used by mammals such as; humans, dogs and hamsters.
Lungs help breathe in air for oxygen and gills help breath in the oxygen contained in the water.
There's many advantages you could have with breathing through gills and lungs, you could swim under water for much longer periods of time and you could obviously walk on land and easily breath the air.
Sorry this took so long to write, I do hope this helped!
Good luck!
Lungs : are used to breath above water
Gills eg: fish
Lungs eg: human’s, lions etc
Animals that have both gills & lungs eg: frog , lungfish etc
Advantages are
Having lungs : can breathe on land
Having gills : can breath in water
Having both : can breath on land and in water
Yes, we all know Pluto is no longer an official planet, merely a dwarf, but it still enjoyed full planet status when New Horizons rocketed from Cape Canaveral, Florida, on Jan. 19, 2006. Plutos demotion came just seven months later, a sore subject still for many.Were kind of running the anchor leg with Pluto to finish the relay," Stern says.The sneak peeks of Pluto in recent weeks are getting "juicier and juicier," says Johns Hopkins project scientist Hal Weaver. "The science team is just drooling over these pictures."The Hubble Space Telescope previously captured the best pictures of Pluto. If the pixelated blobs of pictures had been of Earth, though, not even the continents would have been visible.The New Horizons team is turning "a point of light into a planet," Stern says.An image released last week shows a copper-colored Pluto bearing a large, bright spot in the shape of a heart.Scientists expect image resolution to improve dramatically by Tuesday. The 7,767-mile span at closest approach is about the distance between Seattle and Sydney.New Horizons, weighing less than 1,000 pounds including fuel, has seven instruments that will be going full force during the encounter. Its expected to collect 5,000 times as much data, for instance, as Mariner 4.Were going to rewrite the book," Weaver says. "This is itthis is our once-in-a-lifetime opportunity to see it."The team gets one crack at this.Were trying to hit a very small box, relatively speaking," says Mark Holdridge, the encounter mission manager. "Its 60 by 90 miles, and were going 30,000 mph, and were trying to hit that box within a plus or minus 100 seconds."The only planet in our solar system discovered by an American, Pluto actually is a mini solar system unto itself. Plutojust two-thirds the size of our own moonhas big moon Charon thats just over half its size, as well as baby moons Styx, Nix, Hydra, and Kerberos. The names are associated with the underworld in which the mythological god, Pluto, reigned. New Horizons will observe each known moon and keep a lookout for more.Scientists involved in the 700 million effort want to get a good look at Pluto and Charon, and get a handle on their surfaces and chemical composition. They also plan to measure the temperature and pressure in Plutos nitrogen-rich atmosphere and determine how much gas is escaping into space. Temperatures can plunge to nearly minus-400 degrees.Bill McKinnon, a New Horizons team member from Washington University in St. Louis, Missouri, expects to see craters and possible volcanic remnants. A liquid ocean and a rocky core may lie beneath the icy shell.Anybody who thinks that when we go to Pluto, were going to find cold, dead ice balls is in for a rude shock," McKinnon says. "Im really hoping to see a very active and dynamic world."Pluto has tantalized astronomers since its 1930 discovery by Clyde Tombaugh using the Lowell Observatory in Flagstaff, Arizona. Some of Tombaughs ashes are aboard New Horizons. His two children, now in their 70s, plan to be at Johns Hopkins for the encounter.With its tilted, elongated 248-year orbit, Pluto has made it only a third of the way around the Sun since its discovery. The amount of sunlight that reaches Pluto is so dim that at high noon, it looks like twilight here on Earth. The massive surrounding Kuiper Belt, in fact, is called the Twilight Zone. The New Horizons team has its eyes on a few much smaller objects in the Kuiper Belt, and is hoping for a mission extension as the spacecraft continues toward the solar system exit on the heels of NASAs Voyagers 1 and 2 and Pioneers 10 and 11.For now, signals take 4hours to travel one way between New Horizons and flight controllers in Maryland.New Horizonsscience instruments will be cranked up to collect maximum data Tuesday, leaving no time to send back data. In fact, scientists wont be absolutely certain of success until Tuesday night, 13 hours following New Horizonsclosest approach, when it "phones home."It will be Wednesday before the closest of Plutos close-ups are available for release. And it will be well into next yearOctober 2016before all the anticipated data are transmitted to Earth.

The Asian longhorned beetle is native to China and Korea. The beetle is thought to have entered the United States by means of untreated wooden packing crates. The beetle larvae make tunnels and feed on wood of a wide variety of trees like maple, elm, willow, and birch. Infestation by a large number of these beetles can result in the death of the trees.
Which is the best measure that the United States government can take to limit the introduction of more beetles?
Responses:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Prevent growing trees in and around shipyards.
Introduce predators of these beetles from China or Korea.
Require an inspection and treatment of all wooden packing materials before being imported.
Cut all trees that are infected or are at risk of being infested by the beetles.
Answers
My first answer would be to inspect all wooden packaging materials before being shipped, since that seems to be the way they are being transported from China and Korea to the United States.
My second answer would be to release predatory species concerning this native beetle species to evacuate or kill of the beetle community in the United States. Although, that could create more problems with more non-native species (of the United States), reasoning the first answer to be the best.
The other answers would most likely be worse, since the extermination of possibly infected trees would just kill the trees, which is something we are trying to stop from happening. If we prevent those trees from growing in/around shipyards, the species could still travel through the packaging if it is brought further onto land or use other modes of transportation. Also, the trees were already growing there in the first place, so then 'preventing' them from growing would just lead back to killing the trees that could be infested.

False. The arrow labeled C represents a transfer of carbon dioxide from factory emissions to the atmosphere, and it does not involve the conversion of chemical energy to mechanical energy. This is a chemical reaction in which carbon dioxide is released into the atmosphere.
True. The arrow labeled A represents a transfer of solar energy to chemical energy. Photosynthesis is the process by which plants convert sunlight and carbon dioxide into energy in the form of sugar molecules. This represents a conversion of solar energy into chemical energy in the form of the sugar molecules.
What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection
Answer: Really Sayuri
Explanation:
Plastids, a sizable center vacuole, and a rigid cell wall are all features of plant cells. The cell wall offers skeletal defense and support. Water and nutrients can enter and exit cells thanks to pores in the cell membrane. When water penetrates the plant cell, the cell wall also stops the cell from bursting.
Cell Wall: this provides extra strength and support for the plant cell so it doesn't burst when gaining water by endosmosis.
Chloroplasts: this is where photosynthesis takes place.
Large permenant vacuole: this stores several pigments, ions, enzymes and organic and inorganic substances.

A: One daughter received fewer genes than the other.
B: Each daughter received a different number of genes from each parent.
C: The daughters received a random set of genes from both of their parents.
D: One daughter received all her genes from her father, and the other daughter received all her genes from her mother
Answers
C: The daughters received a random set of genes from both of their parents.
The physical appearance of an individual is determined by their genes, which are inherited from their parents. Each parent contributes half of their genes to their offspring, and the combination of genes from both parents determines the physical characteristics of the offspring.
When the two daughters inherit genes from both their parents, they receive a random set of genes from each parent, which can result in both similar and different physical features. Therefore, statement C is the best explanation for why the daughters' physical appearance includes both similar and different features.

Answers
Answer:
Three agents of dispersal are:
Wind: Some plants have adaptations that allow their seeds to be carried by the wind. Examples include dandelions, which have feathery bristles attached to their seeds that help them float through the air, and maple trees, which have winged seeds called samaras that spin as they fall, allowing them to travel long distances.Animals: Some plants have adaptations that allow their seeds to be dispersed by animals. For example, burrs have hooks or spines that attach to the fur of animals, allowing the seeds to be carried away from the parent plant. An example of a plant that uses this method is burdock. Some fruits, such as berries, are also eaten by animals, which then excrete the seeds in their droppings, allowing them to be dispersed over a wider area. An example of a plant that uses this method is the blackberry.Water: Some plants have adaptations that allow their seeds to be dispersed by water. Examples include coconuts, which have a fibrous husk that can float on water, allowing the seed inside to be carried away by ocean currents, and water lilies, which have seeds that float on the surface of the water and are dispersed by the movement of the water.PLEASE GIVE ME BRAINLIEST!
Also, one of them is wind since the seeds that have wings like dandelions fly with wind.
