There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.

Answer:

Preventive maintenance is where measure are taken beforehand so that the chances of breakdown are minimised resulting in increased efficiency of machines. It is the maintenance that is regularly performed on any equipment to lessen the likelihood of it failing.

An energy pyramid is shown. Which sentence best describes how energy flows through this pyramid? A) Energy is transferred down e
sweet [91]
<h3><u>Answer;</u></h3>

C. Energy is transferred from organisms in one level to those in the level above.

<h3><u>Explanation;</u></h3>
  • Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
  • As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

How does the Earth-<br> sun-moon system<br> affect life on Earth?
klemol [59]

Answer:

Hello!!! Princess Sakura here ^^

Explanation:

The sun, earth, and moon are held together by gravity, and they interact in lots of ways. The moon orbits the earth because of the pull of the earth. The tides are another interaction in the sun, earth, and the moon system. The tides happen because the moon and sun pull on the oceans, causing them to rise and fall each day.

Wild diploid wheat has seven chromosomes in its pollen. Discuss the major events that had to occur for tetraploid pasta wheat to
lianna [129]

Answer:

Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization

Explanation:

Durum wheat (<em>Triticum durum</em>) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: <em>Triticum monococcum</em> (genome AA) and one wild progenitor (genome BB). <em>Triticum durum </em>is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.
