Answer:
C. The growth of top- located buds
Explanation:
Plants secrete chemical messengers that brings about certain physiological development in them. These chemicals are called HORMONES. Gibberellin is one of the important plant hormones released to function in the growth and development of the plant.
Gibberellin plays a major role in bringing about elongation of apical cells, making the plant grow taller. Due to this, Gibberellin is regarded as a growth hormone although it has other functions like fruit ripening etc.
Hence, the growth of top located buds in a plant is a function most likely associated with Gibberellin hormone became it is a growth-stimulating hormone.
Answer:
The false statement(s) is option(3).
That is,
Only one cycling is required per cell cycle 'is false'
Explanation:
Cyclins combine with Cyclin-Dependent protein kinase(CDKs) to form a complex cyclin-CDKs.
This complex comprise so many cyclin, per cycle. This shows that it is a false statement that only one cyclin is required per cell cycle.
The name "Cyclins" came up because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex.
This complex then acts as a signal to the cell to pass to the next cell cycle phase.
After a particular phase, the cyclin degrades, deactivating the Cdk, thus signaling exit from a the phase.
A salt or ester of phosphoric acid, containing PO43− or a related anion or a group such as —OPO(OH)2.
Answer:
Antibiotics have helped in a speedy recovery for human illnesses over the past century.
Explanation:
Because anti biotics were not present centuries ago, many would get sick and even die. However, antibiotics work by affecting things that bacterial cells have but human cells don't. This helps to fight off the bacterial cells and fight infections and viruses, leading to a speedy recovery.
