Whether he can accept or deline his hypothesis for the experiment, the data he observed to prove his experiment hypothesis, and the possible errors of his experiment and how it can be improved
Answer;
-Endosperm
-Cotyledon
The food for dicot embryos is stored in the endosperm while food for monocot embryos is stored in the cotyledons.
Explanation;
-The storage of food reserves in angiosperm seeds differs between monocots and dicots.
-Seeds need a supply of food to support the embryo plant until it can collect its own food. In monocots, there is usually a supply of food, called endosperm, inside the seed coat but separate from the cotyledon. In dicots, the cotyledons contain the endosperm.

Answer:
The lac operon is an operon, or group of genes with a single promoter (transcribed as a single mRNA). The genes in the operon encode proteins that allow the bacteria to use lactose as an energy source. coli normally metabolise glucose, but if glucose is not available in a new environment, the lac operon can allow E. coli to metabolise lactose, the sugar found in milk using the structural genes beta-galactosidase and lactose permease. The lac operon of E. coli contains genes involved in lactose metabolism. ... It normally blocks transcription of the operon, but stops acting as a repressor when lactose is present. The lac repressor senses lactose indirectly, through its isomer allolactose.
Explanation:
<span>Answer:
A. Sodium =1
B. Magnesium =2
C. Aluminum =3
D. Silicon =4

Fluorine is a halogen group that needs 1 more electron to become stable. When it forms a compound with other, the number of fluor atoms depends on the valence electron of the couple. Sodium has 1 valence electron while magnesium has 2, aluminum has 3 and silicon has 4
