This statement is true.
When a hormone binds to a hormone receptor it activates cell enzymes that start a cell cascade. This means that this enzyme makes changes in the activity other proteins or alters the expression of specific genes that change the cells activity.

This function is especially important in the colon.

Patient A is suffering from anemia, due to underproduction of hemoglobin
Explanation:
Patient A’s blood cell count:
Hemoglobin: 5g/dL
RBC: 4.6 x 106 cells/ml
WBC: 15,000 cells/ml
Platelets: 250,000
Results inferred from the count: Low hemoglobin, low normal RBC, high WBC, normal platelets count
Hemophilia is an inherited blood clotting disorder, where due to excessive bleeding, blood hemoglobin, RBC, and platelets can go lower. The low hemoglobin is due excessive loss of blood and not due to underproduction of hemoglobin. Moreover, patient A’s platelet count is normal. Hence, hemophilia can be ruled out.
Since the hemoglobin and RBC count is low, it clearly indicates low production of these blood cell components, leading to anemia. However, the increase in WBC leads can be due any other underlying medical conditions like infections, hemolytic anemia, leukemia etc.
Answer:
Trees create their own food.
Explanation:
Trees like many other plants use photosynthesis to make or "produce" their own food using carbon dyoxide, water, and energy from the sun. This then creates glucose, their own food.
B is the answer to your question.
I hope this helped!
