Helpful bacteria: Decomposers, Nitrogen fixers, Probiotics
Harmful bacteria: Pathogens, Salmonella, MRSA
Bacteria are microscopic,
single-celled organisms that exist in their millions, in every environment,
both inside and outside other organisms. There are many different types of
bacteria. One way of classifying them is by shape. Some bacteria are helpful
while some are harmful.
Peptide hormones are usually produced in the body ahead of the time when they will be required. They are usually synthesized in the inactive form and store in the secretory vesicles just under the plasma membrane. Stimulation of the signalling causes immediate release of these hormones into the surrounding medium or the blood. Thus, cellular response to a peptide hormone is always rapid compared to that of the steroid hormone.
Answer:
More and more staeted showing up
Explanation:
He nebular hypothesis<span> is the most widely accepted model in the field of </span>cosmogony<span> to explain the </span>formation and evolution of the Solar System<span>. It suggests that the Solar System formed from nebulous material. The theory was developed by </span>Immanuel Kant<span> and published in his </span>Allgemeine Naturgeschichte und Theorie des Himmels<span> ("Universal Natural History and Theory of the Heavens"), published in 1755. Originally applied to the </span>Solar System<span>, the process of planetary system formation is now thought to be at work throughout the </span>Universe.[1]<span> The widely-accepted modern variant of the nebular hypothesis is the </span>solar nebular disk model<span> (SNDM) or </span>solar nebular model.[2]<span> It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun's rotation. Some elements of the nebular hypothesis are echoed in modern theories of planetary formation, but most elements have been superseded</span>
