How does a fungus-like protist obtain food?

There are four groups of fungus-like protists: cellular slime molds, plasmodial slime molds, slime nets and water molds. These groups are neither closely related to each other nor to fungi. Cellular slime molds are masses of individual amoeba-like cells that sometimes congregate into slug-like forms to move and reproduce.\nPlasmodial slime molds lose their individual identities as they come together, dissolving the cell membranes between them and becoming single, huge cells with many nuclei. These nuclei float freely within the cytoplasm. Slime nets are made up of multiple individual cells tha..

What can people do to stop water pollution?

Water gets easily polluted when mixed with trash. To prevent polluting rivers, lakes and oceans, it is essential to throw trash in the correct waste bin. Recycling usable trash is also a great solution. Whenever possible, it helps to pick up litter and organize cleaning groups with local people to clean up local waterways. The Natural Resources Defense Council suggests proper disposal of trash and recycling of products. They also recommend the use of natural fertilizers and native plants to retain soil moisture and divert waste from landfills. It is also crucial to dispose of hazardous product..

What is the oxidation state of NaBrO3?

The oxygen atom in most compounds has an oxidation state of 2- and Group 1 metals, such as sodium, have an oxidation state of 1+. Since the oxidation state in the molecule must add up to zero, the oxidation state of bromide can be easily calculated by (2 x 3 – 1).

What is the function of the nuclear envelope?

The outer layer of the nuclear envelope is contiguous with the endoplasmic reticulum. This structure acts as a conveyor belt to transport amino acids along as they are assembled into proteins. The perforated structure of the nuclear membrane suggests that molecular transport across its barrier is important to the early stages of protein synthesis.\nDuring cell division, the nuclear envelope undergoes a dramatic increase in its surface area and the number of pores in its membrane. Simple eukaryotes, such as yeast, divide without disrupting the envelope's surface integrity. In more complex ..

What is the internal motion of atoms called?

Botanist Robert Brown first observed the random motions of pollen on the surface of water under a microscope in the early 1800s. His work was validated in the early 1900s by Albert Einstein, who proved that the motion Brown had observed was caused by the random movements of the molecules of water within which the pollen was suspended.

Why do deciduous trees lose their leaves?

The shedding of tree leaves occurs through a process called abscission. Deciduous trees are found typically in the Northern Hemisphere. Some species of deciduous trees are birch, ash, beech, maple and oak.Unlike deciduous trees, most evergreen trees do not lose their leaves during winter. However, there can be exceptions. For example, the tamarack tree is a deciduous conifer, which has leaves that change color in the autumn, and then they fall off.

What are some fun facts about invertebrates for kids?

Invertebrates also lack skeletons made of bone, and they compensate either with a hydrostatic skeleton, as in the cases of jellyfish and earthworms, or they possess a hard exoskeleton, as in the cases of spiders and insects. Hydrostatic skeletons have pressurized liquid inside of them to give form to bodies. Invertebrates with exoskeletons either have one seamless exoskeleton or different components connected by muscle. Exoskeletons provide a degree of protection by encasing delicate internal organs within a hard outer shell.\nDespite their unique characteristics, invertebrates share many of t..

What is 10 milliliters in grams?

In order to convert from 10 milliliters to grams when the density is known, one would multiply 10 by the density, which is typically expressed as kilograms per cubic meter. The result is then divided by 1,000 to determine the number of grams that 10 milliliters is equal to. Pure water at 4 degrees Celsius has a density of 999.9720 kilograms per cubic meter, which means 10 milliliters of water would equal almost exactly 10 grams.

How do white blood cells fight infections?

Depending on the nature of the pathogen that enters the body, the body's white blood cells can respond in various ways to fight it.Some cell-damaging bacteria release toxins into the body. They do so by latching onto host cells to destroy them. This negative process can be accomplish by the bacteria either consuming the host cell's nutrients, releasing toxins into the cell, simply destroying the structure of the cell or causing the body to have a hypersensitive reaction. White blood cells can release anti-toxins to counteract the effects of this bad bacteria.A particular type of whit..

What are some facts about NASA?

NASA was created by President Eisenhower and Congress in direct response to the Soviet Union putting the first artificial satellite, Sputnik, in orbit in 1957. President Kennedy gave the agency the mission of putting a man on the moon before the end of the 1960s. It succeeded on July 20, 1969, when Neil Armstrong and Buzz Aldrin stepped onto the moon during the Apollo 11 mission. There were 10 more Apollo astronauts that walked on the moon, culminating with Eugene Cernan and Harrison Schmitt of Apollo 17 on Dec. 11, 1972.\nIn 2006, the agency admitted it inadvertently destroyed the original ta..
