<h2>Coelomates &  Pseudocoelomates </h2>

Explanation:

  • Coelomates: Animals that have a body that incorporates voids are known as coelomates, they have a total body structure, and their bodies are ensured by coelom which goes about as a body skeleton and spares all the interior organs from outer pressure. The coelom is shaped at the stage known as gastrula, after various procedures which incorporate different capacities the mesoderm is isolated into two sections and coelom begins existing between them. The primary layer is near the body itself called endoderm while the other layer is at the external side known as ectoderm.  
  • Pseudocoelomates: Animals that don't have an appropriate body hole are known as pseudocoelomates. This is a direct result of the explanation that they have pseudo coelom which is available between the ectoderm and endoderm and lies outside the mesoderm. They are likewise dissipated and present at more than one spots, thusly, have a structure which doesn't appear to be like different species. In spite of the fact that it is a body cavity and capacities appropriately but since of their temperament, the liquid isn't line appropriately however fills the assemblage of creatures, in light of this the organs are put near one another in a dispersed way and thusly doesn't permit the body to shape a legitimate skeleton.

xz_007 [3.2K]

Answer: Decomposer

Explanation:

Bacteria feed on the dead and decaying organism, in which they feed on them and obtain energy from them.

It is not a mutual relation because the host cell on which they feed is not alive. They eat the organic matter that is present in environment.

The bacteria and fungi clean the environment in this way. The dead plants and animals are decomposed in the environment and the nutrients get back  into the soil.

hence, the correct answer is option B

UCU-CGA-GCC-GUU-GGG-UGA how do I convert this into an amino acid using the codon chart, i've been on this forever
bulgar [2K]
So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.
