Answer:
It triggers seed germination by activating hormone.
Explanation:
Karrikins has a great effect on seed germination in the plants as well as the obligate parasitic weed plants because it trigger the germination of seed by signaling of hormone known as strigolactone which is responsible for the germination of see. Karrikins are the group of plant growth regulators which is present in the smoke of burning plant.
c-MYC is believed to be responsible for the lymphoma because : c-MYC dysregulation which induces lymphomagenesis by loss of the tight control.

What is Burkitt Lymphoma (white blood cell) ?</h3>
Burkitt lymphoma is a germinal center B-cell-derived cancer that was instrumental in the identification of MYC as an important human oncogene more than three decades ago.
Recently, new genomics technologies have uncovered several additional oncogenic mechanisms that cooperate with MYC to create this highly aggressive cancer. The transcription factor TCF-3 is central to Burkitt lymphoma pathogenesis.
TCF-3 is rendered constitutively active in Burkitt lymphoma by two related mechanisms: somatic mutations that inactivate its negative regulator ID3, and somatic mutations in TCF-3 that block the ability of ID3 to bind and interfere with its activity as a transcription factor.
TCF-3 is also a master regulator of normal germinal center B-cell differentiation. Within the germinal center, TCF-3 up-regulates genes that are characteristically expressed in the rapidly dividing centroblasts, the putative cell of origin for Burkitt lymphoma, while repressing genes expressed in the less proliferative centrocytes.

Answer:
Pancreas.
Explanation:
Pancreas may be defined as the merocrine gland that can acts as an endocrine gland as well as an endocrine gland. Pancreas releases the important hormone known as insulin and glucagon.
Sasha is a diabetic patient and cannot digest carbohydrate properly. Her pancreas is not working properly as the pancreas release pancreatic amylase that helps in the digestion of carbohydrate. The abnormal secretion of insulin hormone may cause diabetes that disrupts the level of carbohydrate in the body.
Thus, the correct answer is pancreas.
Answer:
Many evolutionary changes resulted in the transition of aquatic vertebrates into terrestrial organisms. Some of these are:
In terrestrial organisms, the respiratory system is more complex and enhanced than the aquatic vertebrates. For instance, the early amphibians had gills for respiration. But with the passage of time, lungs appeared which made life on land more feasible.
The formation of rigid and insulated body coverings also was an adaptation that emerged for making life feasible on land.
Limbs allowed movement on land. With the passage of time, feet developed from the limbs.
Answer:
It will probably stop fish migration
Explanation:
Fish have to migrate so they don't die from the cold or starvation. They swim upstream and eventually reach there destinations. If a dam is in the way it will cause the fish to have a block in there path and they will eventually die
