The cell wall is made up of tough stringy cellulose fibers.
Hope this helps!!
Answer:
C
Explanation:
You are testing the affects of different soils on the germination of seeds, therefore, you must compare different types of soil. The other answers don't have correlation to different types of soils, and are incorrect.
Answer:
The process of gene cloning involve multiple steps. It involves many enzymes, bacterial cell, vector to produced an amplified number of cell and hence product.
The gene of interest is find and then it is carried into the bacterial cell by the help of vector.
The vector is then carried to get incorporated into the bacterial cell. In this way the bacterial cell starts replicating and the and the desired product is produced in high amount.
Answer: position of the carbonyl carbon
Explanation:
In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.
Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.
But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.
In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.
In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon
