How does a flash flood compare to flooding?

Answers

Answer:

Flood: An overflow of water onto normally dry land. ... Ponding of water at or near the point where the rain fell. Flooding is a longer term event than flash flooding: it may last days or weeks. Flash flood: A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours.

Explanation:

Answer:

They both cause floods and fill up some places and they are both sometimes caused by rains or broken dams for a pretty long time. Flood is caused by rain and bad weather while flash flood is the result of water overflowing from a contained location like a lake, river or reservoirs. Flood is a term that can be used to describe any type of water overflow while flash floods are specific to broken dams, overflowing lakes and clogged rivers. The word flood both stands for their meaning.

Scientists think that all modern plants, animals, and fungi can be trace to protist ancestors because the protists is the root of all eukaryotic diversity. ... The function that do cilia and flagella in protists carry out is movement. The first multicellular animals presumably evolved from colonial protists (most likely choanoflagellates), and within the colonies, cells progressively differentiated from one another, acquiring specific functional characteristics. It may sound like a bit of a stretch, but in fact such a phenomenon can be observed in colonies of extant unicellular organisms, both prokaryotes and eukaryotes, where some cells of the colony can become differentiated under particular environmental conditions. We can speculate that early in the history of animals some differentiation genetic programs evolved, got stabilized, and became inheritable from one generation to the next. Once different populations of cells were established in the colony, the door was opened to further specialization. Specialized cells were not initially grouped in organs but were more like regionalized populations or layers of cells, as we see in sponges, and morphogenesis progressively evolved

Answers

Answer: 2, 4 and 5.

Explanation:

Human system are made of various organs which in turn are made up of various tissues which in turn are made up of various cells. Cells are therefore much more numerous than systems.

As already mentioned, organs are made up of tissues which are made up of cells so statement 4 is right.

As systems are made up of various organs working together, they are more complex than the individual organs. For instance, the Muscular system is more complex than the triceps or bicep muscles.

The oxygen released during photosynthesis comes from molecules of water
True or False

Answers

Answer: False

Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as:  H 2 O + 2 photons --> 2 e  −   + 2H  +   + O.  Here, the electrons released are accepted by the photosystem to fulfill the electron gap. The last electron acceptor is the oxygen and thus, the oxygen is liberated from the water molecule. The experiments conducted by Samuel Ruben and Martin Kamen by using radioactive isotopes helped to prove that the oxygen liberated during photosynthesis came from photolysis the water.

Explanation:

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.Carbon dioxide is released during photosynthesis. Plants which synthesise their food themselves are called saprotrophs.

TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.

Answer:

Explanation:

tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n
