Is Yeast A archaea?
Yeasts are eukaryotes belonging to the Fungi kingdom and so contain membrane-bound cell organelles, like the nucleus, which houses the genetic material of the cell. Unlike most fungi that grow as long thread-like hyphae, yeasts are fungi that exist as single cells.
Are Animalia terrestrial or aquatic?
now Animalia, Animalia don’t have a cell wall and are all multicellular most of them are sexual reproduction they live in both terrestrial and aquatic environments they are eukaryotic and are heterotrophic.
How do archaebacteria eat?
Archaea are like bacteria – they are single cells that don’t have a nucleus – but they have enough differences from bacteria to be classified all by themselves. They do things pretty much like bacteria in general – they transport food molecules into themselves through protein pumps or channels in their outer membranes.
What is a valid domain?
A valid domain name character is that which contains a set of alphanumeric ASCII characters (i.e., a-z, A-Z), numbers (i.e. 0-9) and dashes (-) or a combination all of these. It’s a domain name that has the valid characters and length. It mostly has a minimum of 3 and a maximum of 63 characters.

How do you register a top level domain?
It is very easy to register you top level domain name. Just go to any Domain registrar like GoDaddy, Namecheap or any domain registrar you can find in Google. Search for your required domain name. Use your Credit/Debit card to pay for the domain.
What is an example of a top level domain?
Top-level domain ( TLD ) refers to the last segment of a domain name, or the part that follows immediately after the “dot” symbol. TLDs are mainly classified into two categories: generic TLDs and country-specific TLDs. Examples of some of the popular TLDs include .com, .org, .net, .gov, .biz and .edu.
What is a domain name extension?
A domain extension is the top-level part of the domain name ( TLD ), such as .com, or .net. A majority of sites use .com, making it easy to forget that at their inception, each domain extension had a specific intended purpose. Well, that rings true today, even though the lines have been somewhat blurred.
