Answer:
B)
Explanation:
Natural selection describes how organisms change, and adaptation explains why. Charles Darwin, theory.
The primary hormone that the thyroid gland releases into the bloodstream is thyroxine. It is the inactive form, and organs like the liver and kidneys convert the majority of it into the active form triiodothyronine.
The body's metabolism, cardiac and digestive processes, muscle control, brain growth, and bone maintenance are all significantly regulated by thyroid hormones.
Hypothyroidism refers to the thyroid gland producing too little thyroxine. It could be brought on by autoimmune conditions, inadequate iodine consumption, or the use of specific medications. Sometimes there is no known cause. Untreated throxine before birth or during infancy can result in mental disability and stunted growth because thyroid hormones are crucial for both physical and mental development.
Adult hypothyroidism results in a slower metabolism. It may cause symptoms like weariness, a diminished ability to tolerate cold conditions, a low heart rate, weight gain, decreased appetite, impaired memory, sadness, muscle stiffness, and decreased fertility. For further details, read the article on hypothyroidism.

Answer: Option B.
Biogeographical
Explanation:
Biogeographical evidence is the evidence that provide information of organisms distribution over geographical areas. It provide information on how and when the organisms evolved and common descent.
Frombthe question, biogeographical evidence will help Darwin make his observation
Answer:
The correct answer is C. NADP⁺
Explanation:
NADP+ is the coenzyme that acts as the electron carrier during the photosynthetic process. The electron that is released from the splitting of water pass through the electron transport chain and at the end of the chain the electron is received by an electron carrier called NADP+.
So this passing of electron causes the transport of H ions in the thylakoid lumen from the stroma and when these ions come back through ATP synthase it forms ATP. Then these NADPH and ATP are used in the Calvin cycle to fix the CO2 into complex form. Therefore the correct answer is C. NADP⁺.
Options:
A. horse
B. bacterium
C. oak tree
D. starfish
The answer is ''starfish" or option D. Mitosis is cell division that includes two daughter cells that actually has the same amount of chromosomes as each other. (most likely twins) Mitosis is also part of the cell cycle with meiosis which helps the organism remain homeostasis and homeostasis is the process organism used to stay cold on a arm day, or stay warm on a cold day.
Hope this helps!
