There is a tube called the vascular system found in most plants with a vascular system. This system transports water and nutrients throughout the plant's body and helps out during photosynthesis.
Out of the choices given, the best way to describe the organisms of the Precambrian era are they were single-celled organisms and soft, boneless animals. One thing from that time that we still have today is the jellyfish. The correct answer is C.
The lipid bilayer<span> has been firmly established as the universal basis for cell-</span>membrane<span> structure. It is easily seen by </span>electron<span> microscopy, although specialized techniques, such as x-ray diffraction and </span>freeze-fracture electron microscopy<span>, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the </span>lipid<span> molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions</span>
The answer is; The frequency for allele O = 0.7746 while that of o = 0.2254
Well use the hardy Weinberg equation of a population at equilibrium; p2 + 2pq + q2 = 1
In our case, p2 will be 60/100 = 0.6; therefore p = square-root of 0.6 = 0.7746
Remember also that the frequencies of alleles of the same gene add up to one (1); i.e p + q = 1
Therefore q = 1 – 0.7746 = 0.2254
5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
<h3>Given</h3>
Mass of oxygen at room temperature =500.0 ml
Volume of pressure = 50 atm pressure.
The gas to a volume = 150.0 ml
<h3>Explanation</h3>
The volume decreases by the factor = 500.0 mL / 150.0 mL
= 10 / 3
The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to
= 5.00 atm
So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
