Option A Base pair substitution
The answer is that <span>all
veins carry blood back to the heart, except for the pulmonary vein. the
vena cava empty into the right side of the heart, so they technically
bring blood to the
</span>main atrium.
Dead organic matter from the plants in the form of litter and root exudate (including acids, sugars, polysaccharides and ectoenzymes) and dead roots are processed by living organisms in the soils.
<span>For example, earthworms may substantially improve soil condition in newly formed soils, such as in post mining sites. In the same time, earthworms can also cause severe negative impacts by bringing invasive exotic species to the ecosystem.</span>
Plants<span>, </span>animals<span> and micro-organisms (fungi and bacteria) all affect </span>soil formation<span> by producing or contributing to humus production. The amount of humus in a </span>soil<span> is a result of how much </span>plant material has been incorporated into it.
(12g)/(75.398cm^3)
=0.159 g/cm^3
answer would be = 0.16 g/cm^3
Answer:
The three main types of lipids are - triglycerides, diglycerides, and steroids.
Explanation:
Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.
An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.
A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.
Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.
