Explanation:
Lactobacillus acidophilus (below) is a probiotic microorganism typically found in the human small intestine. It has a cell wall made of peptidoglycan. It aids in the process of digestion and can commonly be obtained through sources such as acidophilus yogurt. Which characteristic proves Lactobacillus acidophilus is from the specific kingdom Eubacteria?
It is multicellular.
It has a cell wall.
It is a microorganism.
It has peptidoglycan.
The right answer is It has peptidoglycan.
Eubacteria are not multicellular beings, but are unicellular.
Eubacteria certainly have a cell wall, but we must not forget that plant cells also have a cell wall, so this is not really a feature.
Eubacteria are microorganisms but there are eukaryotic microorganisms, so it is not a characteristic.
Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a characteristic component of the bacterial wall (not found elsewhere) maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.
The National Wildlife Refuge provides land for fish, wildlife, and plants.
True
False
True
The The National Wildlife Refuge were started in 1903 when there was need to save brown pelicans. This refuge provides home to more than 700 varieties of birds, more than 1000 species of fish, 250 kinds of reptiles and amphibians. They also provide home to countless number of invertebrates and wildlife. Along with animals the National Wildlife Refuge also provides shelter to a large number of plant species.
The statement is true.
National Wildlife Refuge is the United States premiere network of public lands and waters which provide habitat for fish, wildlife and plants. It is administrated by the US Fish and Wildlife Service and thus looks after the protection of endangered and vulnerable species. It manages migratory birds and restores nationally significant fisheries in the country.
Remoras, or scker fish, attach themselves to sharks and travel with them. When the sharks feed, the remora detach themselves and feed on pieces of fish the sharks left behind. What two types of interactions are described in this scenario?
a.
Predation and commensalism
b.
Predation and mutualism
c.
Competition and parasitism
d.
Competition and commensalism
The right option is; a. Predation and commensalism
Predation is an interaction between organisms in which one organism (the predator) benefits from another organism (the prey), while commensalism is also an interaction between organisms of different species in which one species benefits from the other without either harming or benefiting the latter. From the question, the remoras benefits from the relationship by living on sharks and feeding on the leftovers of the sharks, but the sharks are not affected in any way. The relationship describes predation and commensalism.

5. A relatively rapid form of mass movement that is most common in dry mountainous regions is _____.
*creep
*a mudflow
*a slump
*an earthflow
6. The average annual precipitation worldwide must equal the quantity of water _____.
*evaporated
*transpired
*infiltrated
*locked in glaciers
7. The ability of a stream to erode and transport materials depends largely on its ______.
*width
*length
*velocity
*density
8. The vertical drop of a stream channel over a certain distance is called _____.
*discharge
*channel roughness
*gradient
*runoff
Mass movements are driven by gravity and can range from slow creeps to rapid landslides. The key factors in these phenomena are the steepness of slopes, type of material, and climate. The eroding and transporting power of a stream depends on its velocity, and the gradient defines the stream's vertical drop.
Explanation:The force behind mass movements is, indeed, gravity. Mass movements always trend downslope due to the gravitational force. However, it's not accurate to say mass movements always lead to landslides; they vary in speed and scale. They could be a slow creep or a rapid avalanche.
Oversteepened slopes often lead to mass movements due to their angle being greater than 40 degrees. A block of material moving downslope along a curved surface is commonly referred to as a slump.
A rapid form of mass movement common in dry mountainous regions is rockfall. Water balances in the world environment are maintained since the average annual precipitation worldwide must match the quantity of water evaporated. The power of a stream to erode and transport material mainly depends on its velocity, rather than its width or length.
The vertical drop of a stream channel over a preset distance is described as its gradient.

Answer: The matching answers for the question are-
1) The genetic material is duplicated- Interphase
2) Chromosomes move to opposite ends of the cell- Anaphase
3) Chromosomes become visible; the spindle apparatus forms- Prophase
4) The cell plate forms; the nuclear envelope is formed- Telophase
5) The chromosomes line up in the middle of the cell - Metaphase
The cell cycle is broadly divided into two phases- Interphase and M phase. Cell cycle begins with interphase. In this phase, the growth of cell and duplication of genetic material takes place.
This is followed by the M phase. This phase is further divided into Prophase, Metaphase, Anaphase, and Telophase.
In Prophase, chromatin condensation occurs which gives discrete chromosomes. The nuclear membrane breaks down and spindles are formed at the opposite poles of the cell.
In Metaphase, chromosomes line in the center of the cell.
In Anaphase, chromosomes move to opposite poles of the cell.
In Telophase, the cell plate forms; the nuclear envelope is formed from the remnant pieces of nuclear envelope of the parent cell.
After all these changes, genetic content gets divided into two cells.
Answer:
1. Inteph
2. Anaph
3. Metaph
4. Teloph
5. Metaph
The process of a parent cell dividing into a large number of genetically identical cells all at once is known as _____ .
Final answer:
The process where a cell divides into many genetically identical cells all at once is called multiple fission, while mitosis refers to the division producing two identical daughter cells.
Explanation:
The process of a parent cell dividing into a large number of genetically identical cells all at once is known as multiple fission. While the cell division in somatic cells, where a parent cell divides to produce two genetically identical daughter cells, is called mitosis, the process of multiple fission can produce more than two daughter cells. It is a form of asexual reproduction observed among protists and other single-celled organisms. However, binary fission is another type of cell division typical in prokaryotic organisms like bacteria, where the parent cell splits into two daughter cells. Despite the difference in the number of cells produced, both binary fission and multiple fission result in offspring that are genetically identical to the parent.
what part of an original isotope number of atoms remains have two half life
Half-life is the time taken by a substance (molecule, drug or other) to lose half of its proportion. Used by extension in the field of radioactivity, the half-life, also called radioactive half-life, is the time at which half of the radioactive nuclei of a source have disintegrated.
The term half-life is often misinterpreted: two half-lives do not correspond to the full life of the product. The half-life is, in fact, the median of the life of a product, that is to say, the duration below which there remains more than 50% of the product, and beyond which there remains less than 50%. So two half-lives correspond to the duration where 50% of the 50% of the product remains, ie 25% (the quarter).

A blood bank asserts that a person with type O blood and a negative Rh factor (Rh−) can donate blood to any person with any blood type. Their data show that 49% of people have type O blood and 15% of people have Rh− factor; 45% of people have type O or Rh− factor. Find the probability that a person has both type O blood and the Rh− factor.
Answer:
Probability of a person having both type O blood and the Rh− factor is [tex]19[/tex]%
Explanation:
The probability of a person having O blood group is [tex]0.49[/tex]
The probability of a person having Rh- factor is [tex]0.15[/tex]
The probability of a person having either O blood group or Rh- Factor is [tex]0.45[/tex]
Hence, As per the additive rule of probability

Months after a forest fire, some nonnative plants began to grow in the area. why were these plants able to grow?
Final answer:
Nonnative plants are able to grow after a forest fire due to the increased availability of sunlight and open space after the elimination of the dominant tall trees. This process is part of secondary succession, which leads to the eventual recovery and formation of a new climax community.
Explanation:
After a forest fire, the dominant tall trees that previously shaded the ground and absorbed most of the sunlight are no longer present. This loss of canopy opens the area to sunlight, allowing nonnative plants and pioneer species to grow. These plants are often well-adapted to thrive in the open, sunny, and disturbed conditions that a fire creates. The process through which a forest recovers after a disturbance like a fire is known as secondary succession.
Initially, annual plants and grasses will colonize the area because they grow quickly and can take advantage of the sudden abundance of sunlight and space. As these pioneer species alter the environment, such as by enriching the soil with their decomposing biomass, the area becomes more accommodating for other plants like shrubs and eventually small pine, oak, and hickory trees, referred to as intermediate species. Over time, a new climax community forms, resembling the original forest's species composition.

Soils close to the equator are always darker. ...?
Answer:
3
Explanation:
please anyone?
True or False. Wind blows due to the differential heating of earth's surface.
True
False
Heat's effect on the wind cycle is most easily observed near the sea. During the day, the ocean absorbs heat from the surface, keeping the air above it cooler than above the land. When the warm air rises from the shore, the cooler air from the ocean blows in to take its place. At night, the land cools quickly, while the ocean radiates the heat it absorbed, keeping the air above warm. This reverses the effect, causing the air offshore to rise and creating a breeze from the land. Uneven heating can also occur due geographical features. A mountainside exposed to the sun will warm more than a shadowed valley below it, creating a wind that blows uphill during the day and downhill at night.
The same principle is responsible for global wind patterns. The polar regions receive less solar radiation than areas near the equator, resulting in a global shift in temperature according to latitude. This, along with differences in temperature and density in various layers of the atmosphere, creates global wind patterns like the jet stream that help drive weather systems.

Water is unusual because it expands as it freezes. Very few substances have this property. The reason liquid water is more dense then ice can be best explained by? A) water is the universal solvent. B) Water has an unusually high boiling point. C) Water contains elements that are not common in other substances. D) Water is polar and the positive and negative ends of the molecule attract each other.
The correct answer is option D) Water is polar and the positive and negative ends of the molecule attract each other.
The water is a polar molecule, and forms a hydrogen bonding with the other water molecule. In the liquid state, the molecules of the water is in random motion, and the bond between the water molecules are continuously formed and deformed.
In the ice, the hydrogen bond between the water molecules become more stable, due to this, the molecules arrange themselves in a hexagonal pattern. Due to this arrangement, the allover space occupied is expanded. Hence, the ice is expanded than liquid water.
Sand dunes are formed by _____.
volcanoes
erosion
convergent faults
divergent faults
Answer: erosion
Erosion is the process of removal and displacement of surface soil particles by the effect of wind, water or chemical agent. The sediments due to the effect of these agents gets displaced to locations other than the one where their parent rock or soil originated. A sand dune can be defined as the accumulation of grained sized sand into the shape of ridge by the effect of wind under the influence of gravitational force exerted by the earth. Dunes are formed when the loose sand is blown by wind. Therefore, sand dune is the erosion of sand by wind. Sand dunes are formed in deserts, beaches, barren fields and semiarid regions.
