The energy released when sugar molecules are broken down is transferred to bonds in which molecule

1 answer:

8 0

Sugar molecules (i.e. glucose) are broken down into simpler molecules such as pyruvate. Pyruvate, in the presence of oxygen will be converted to Acetyl-CoA and it will enter the tricarboxylic acid cycle wherein it will produce series of reducing compounds such as NADH and FADH. These reducing compounds are then processed in the electron transport chain and oxidized, and the energy released in the oxidation of NADH and FADH is transferred to the high energy phosphate bond of adenosine triphosphate or ATP.

Part E Your molecular clock model resembles another branching chart, the phylogenetic chart, which you’ve used in this unit. Rev

Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

The ______ system is assisted by the lymphatic system and the physical barriers of the skin and gastrointestinal tract.

mezya [45]

Answer:

The correct answer is- Immune system

Explanation:

There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.

The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.

Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.

So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.

How do you get from DNA to protein? Help

borishaifa [10]

DNA is transcribed into RNA, 1 base of DNA corresponds to 1 base of RNA, this 1 to 1 relation is not used in the translation to protein. During this translation, 1 amino acid is added to the protein strand for every 3 bases in the RNA so before double stranded DNA is turned into protein it first goes through a process called transcription.
