When washing the dishes, you most likely used an animal from the _____ phylum. Porifera, Cnidaria, Nematoda, or Mollusca

The correct option is this: IT HAS PEPTIDOGLYCAN.

Eubacteria are those bacteria that are considered to be real bacteria and they can be found virtually everywhere. They are prokaryotes and thus lack true nucleus. They are normally categorized based on their shapes. One specific characteristic of eubacteria is their possession of cell walls that are made of peptidoglycan, this chemical strengthen their cell wall and enhance their ability to withstand hostile environments.

Answer:

A. decomposition

Explanation:

Decomposers are microorganisms such as bacteria, fungi and worms. These organisms are significant decomposers which can break down most types of organic matter. All the living organisms are made of carbon. They all require carbon their growth and reproduction. Decomposers decompose dead organisms and use the carbon dioxide released from them for their food. Therefore, decomposers help in cycling of carbon from dead bodies into the atmosphere through cellular respiration.

The hetotrophs depend upon the Autotrophs for making their own food and comparison of autotrophs to heterotrophs are as follows.

Comparision of autotrophs and hetotrophs.

Autotrophs

• An organisms that prepare their own food through photosynsthesis process is called autotrophs.
• Autotrophs also known as producers.
• Autotrophs store chemical energy in carbohydrate food molecules they build themselves.
• Example of autotrophs are plants, algae and some bateria.

• They cannot  eat other organisms and their byproduct.
• In food chain, autotrophs make up the first trophic levels.

heterotrophs

• The organisms that cannot prepare their own food and depends on others.
• It is also know as consumer.

• The heterotrophs cannot store chemical energy in carbohydrate food molecule.
• Example of heterotrophs are animals, fungi and many bacteria.
• They can eat other organisms and their byproduct.
• In food chain, heterotrophs form the next trophic levels after plants.

Answer: B) ATP to ADP

This reaction is termed as ATP hydrolysis.

ATP ( adenosine triphosphate) conversion to ADP ( adenosine diphosphate) is an energy producing reaction ( exothermic reaction). ATP contains high energy bonds called phosphoanhydride bonds. Thus, when this bond is broken down, ATP is converted to ADP and Pi ( inorganic phosphate) and  releases large amount of energy.

Answer:

The correct answer is option A. "skin".

Explanation:

Hair and nails are derived from cells of the skin. The cells of the skin have keratin, a protein that creates a protective barrier against the environmental factors that could affect them. The hair and nails are modifications of skin cells, that have keratin but with additional features. The hair is made of 95% keratin and is formed of three components: medulla, cuticle and cortex. The nail cells are made from keratin as well, forming a horn-like structure that is replaced by skin cells constantly.
