Answer:

Decomposers.

Explanation:

Decomposers break down dead matter to recycle it back into the ecosystem. Have you ever seen mushrooms on a dead log? They're there because they are breaking down the dead matter, which gets recycled back into the Earth.

Hope this helps! :)

(Select all that apply.) Which of the following does the plant need in order for it to germinate and develop? genetic informatio

tatuchka [14]

Answer:

genetic information, energy, soil

Explanation:

Germination is the term used to describe the set of steps that allow the development of an embryo within the seed of the plant. The development of this ambrion will result in the emergence of a seedling that will develop and form a very important plant for the ecosystem. In short, germination is the process of transforming the seed into a new plant.

In order for this to occur, the seed needs some factors that degrade its entire development. These factors are genetic information, energy and soil

A nurse is providing disaster care in an event that is known to involve gamma radiation. when admitting victims of the disaster,

Y_Kistochka [10]

For the answer to the question above, the nurse must remove victim's clothing and have them wash thoroughly.

The nurse should've victim's shower and change clothes and irrigate or wash open wounds with soap and water. Cleansing the skin helps to reduce the transition from external to the internal radiologic contamination. Infectious micro-organisms are not involved, so chlorhexidine is of no particular benefit. Applying PPE over contaminated clothing could make the risk of injury worst. Good ventilation is very important, also the removal of contaminants is the priority because of the increased risk of injury.

Are the organelles that process coded genetic messages and assemble amino acids into proteins

g100num [7]

Answer

Ribosome is an imporatnat cell organelle that play a key role in protein synthesis.

Discovery

Ribosome was discovered by Palade in 1955.

Structural composition

Chemically it is composed of an equal amount of rRNA and proteins, thats why it is also known as ribonucleoprotein.

Sub units of ribosomes

Ribosome is composed of two sub units one is smaller and the other one is larger. Both units are attached with each other with help of Mg atom.

Size of ribosome

In prokaryote the ribosome size is 70S, while in eukaryotes its size is 80S.

Polysome

When many ribosomes are attached to one mRNA strip it is called polysome or poly ribosome.

Role of ribosome

Ribosomes are the sites of synthesis of protein from amino acids.

Mechanism

mRNA which is the exact copy of DNA and formed in transcription come out from nucleus and attached to ribosomes. Now tRNA catch amino acids and come toward ribosome where its anti code match with genetic code of mRNA and then bonded to it. In this fashion a lot of amino acids are accumulated which make bonds with each others. Thus message present on mRNA in the form of genetic codes convert into protein through the process of transliteration.
