Steroids are defined as active organic bio-molecules, having four rings with a specific molecular configuration. Steroids play role in two major functions: as hormones or signaling molecules and as structural components of plasma membrane.
Examples of steroid hormones are estrogen, progesterone, and cortisol. Thus, the correct answer is 'option b). they serve as chemical messengers.'
<span>Lithosphere includes all the Earth known to us: the mountains, the ground we walk on, etc. It's solid - else we would not be able to walk on it! the more inner layers of Earth are liquid, but lithosphere, the outermost layer is solid. The tectonic plates are not floating on the lithosphere - they form the lithosphere! So the correct answer is A - it is solid and composed of crust and upper mantle (outer later)</span>
A mutation can either be passed down as a hereditary trait, but most mutations of the gene can be triggered by something such as radiation from the sun, or if an error is made in cell division as DNA copies itself
The plant's production of high-energy sugars would reduce significantly. I'm not going to say that the plant would completely stop producing the sugars because it has to respire, and one product of respiration would be carbon dioxide. This carbon dioxide would be recycled so that the plant can photosynthesize and produce sugars.
