Later the nervous system signals the endocrine system to stop releasing the hormone when the body does not need anymore. this is called negative feedback. The nervous and endocrine systems work together when the endocrine system stimulates the brain, which in turn stimulates hormone-producing organs Cheers -Irys
Answer;
- phosphate group
- Ester functional group
- Alkene
- Alkane side chains.
Explanation;
Phospholipids are types of lipids that are major components of the cell membranes.
They consist both the hydrophillic (water loving) and hydrophobic (water hating) ends.
The major functional groups in a phospholipids are;
- the phosphate groups - PO4
- The Ester functional group- - COO-R
- Alkene side chain - -CH=CH-
- Alkane side chain - -CH-CH-
Answer:
E. 6:3:3:2:1:1
Explanation:
Look at the attached picture to see the Punnett square for your problem.
The cross for this is snapdragons who are heterozygous for both traits so the cross would be:
<em>TtRr x TtRr</em>
As you can see in the image, you have the following genotype combinations with the corresponding phenotype combinations:
GENTOTYPE PHENOTYPE NUMBER
TTRR Tall - Red 1
TtRR Tall - Red 2
TTRr Tall - Pink 2
TtRr Tall - Pink 4
TTrr Tall - White 1
Ttrr Tall - White 2
ttRR Short - Red 1
ttRr Short - Pink 2
ttrr Short - White 1
The following phenotype combinations in summary would then be:
Tall - Pink: 6
Tall - Red: 3
Tall - White: 3
Short - Pink: 2
Short - White: 1
Short - Red: 1
So the ratio is 9:3:3:2:1:1
