Part 1 - Pick one abiotic factor and change it dramatically. (Example: remove it completely or increase it A lot)
zubka84 [21]
1. Water is abioitic and is needed by every living organism Soil is abioitic and is needed by plants Trees and other plants release water vapor from their leaves (a process called transpiration) that create humidity (which in turn influences how much rain falls in an area) The climate in an area influences the special adaptations that plants and animals have. For example: warm fur coats and thick layers of fat to keep warm in cold climates, animals in dry, hot climates (desert) have large ears to release heat and cool down. Biotic factors also influence abiotic factors. Animals produce waste (go to the bathroom) which in turn will become nutrients in the soil.
2. decrease heat will affect biotic factors, like animals, warmth.

What is the best explanation for the observation that eukaryotes that seem superficially simple can have much larger genomes (in
brilliants [131]

Answer:

Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.

Explanation:

DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.

Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.

Thus, the correct answer is option (b).

Briefly outline the steps involved in glycogen synthesis and breakdown and explain the regulatory mechanism involved in glycogen
Elenna [48]

Answer:

Glycogen is synthesized and degraded by different pathways, which provide greater flexibility for energy production through its degradation or for storage in its synthesis and thus maintain control of both metabolic pathways.

Explanation:

Synthesis and degradation pathways:

1º.- activation of glucose units at UDP-glucose.

UDP-glucose is an activated form of glucose, which is formed in a reaction catalyzed by UDP-glucose, which is formed in a reaction catalyzed by UDP-glucose pyrophosphorylase. This reaction is an example of biosynthetic reactions that are directed by the hydrolysis of pyrophosphate (PPi-2Pi).

Many biosynthetic reactions are directed by the hydrolysis of pyrophosphate, which catalyzes pyrophosphate hydrolase or pyrophosphatase, and is very favorable thermodynamically.

2nd.- polymerization or addition of glucose units to glycogen. Two steps: addition and branching.

 UDP-glucose acts as the giver of glucose units for glycogen synthesis. Glucose transfer

from the UDP-glucose to a growing glycogen chain is catalyzed by glycogen synthase.

A branching enzyme [amyl (1,4 -> 1,6) -transglucosidase], moves a chain of about seven glucose residues, to form

bonds (α1-> 6) at the branching points.

To start glycogen synthesis, glycogen synthase is only effective when it is linked to glycogenin. Glycogenin is

an oligosaccharide carrier protein formed by glucose units with linkages (α1-> 4).
