Describe beadle and tatum’s experiments with neurospora and explain the contribution they made to our understanding of how genes control metabolism

Beadle and Tatum caused a Neorospora collision with x-rays, and then watched for mutants that shows another form of nutritional needs from the wild-type models.

These Mutants had difficulty in feeding but can strive where there is a complete growth medium

This brought them to the conclusion that their genes may have been mutated and transformed to control its own metabolism.

-Beadle & Tatum used Neurospora-experiments showed genes control metabolism

Explanation:

Wild type Neurospora can strive where there is minimal medium of agar, inorganic salts, glucose, and the vitamin biotin. Beadle and Tatum did a series of experiments which involves placing the different forms of mutants into vials which have the minimal medium and a single growth nutrient.

The nutrient that promotes growth showed the enzymes that were still functional and none functional ones.

Thus brought them to the conclusion that genes act by influencing the formation of a specific enzyme.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
