When the sea floor spreads or collides it creates breakages which would be ocean ridges and deep sea trenches
Chemicals produced by bacteria that limit the growth of other bacteria are called antibiotics.
The biggest influence on basal metabolic rate (BMR) is exerted by hormones from the thyroid gland — T3 thyroid hormone.
<h3>What are T3 levels a sign of?</h3>
- A person's thyroid is producing enough T3 hormone when their T3 levels are normal.
- Low levels may be a sign of hypothyroidism, while high levels may be an indication of hyperthyroidism.
- T3 levels, however, can also be influenced by other variables, such as pregnancy and some drugs.
<h3>What takes place when T3 levels are high?</h3>
High total T3 or high free T3 levels in your test findings could indicate hyperthyroidism.
You may have hypothyroidism, a condition in which your body doesn't produce enough thyroid hormone, if your T3 levels are low.
To assist in the diagnosis of thyroid illness, T3 test results are frequently matched with T4 and TSH test findings.

<span>Invertebrate<span>, </span>any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.</span>
