The answer I believe is number 1
<span>Penile shaft
</span>During erection, blood<span> flows into the spaces, causing distention and elevation of the penis. The amount of blood entering the penis can be increased by physical or psychological stimulation. As blood enters, there is a temporary reduction in the rate and volume of blood leaving the penis. The arteries carrying blood to the penis dilate; this, in turn, causes tissue expansion. The veins leading from the penis have funnel-shaped valves that reduce the outflow of blood. As the erectile tissue begins to enlarge, the additional pressure causes the veins to be squeezed against the surrounding fibrous tissue, and this further diminishes the outflow of blood. Essentially, blood becomes temporarily trapped in the organ.</span>
Agglutinins are a type of antibody. Antibody are proteins that specialize in recognizing foreign invaders in the body so that they can be eliminated. In the human body, agglutinins function by causing pathogens to clump together; they act as a sort of gum or glue, which make this pathogens to stick together, this inactivate the pathogens and marked them out for elimination from the human system. Thus, agglutinins act like security guards by arresting disease causing organisms that enter the body.
I believe the answer is the first option.
Answer;
Six carbon dioxide (CO2) molecules were used to make it.
Explanation;
-Glucose is manufactured in the process of photosynthesis, which is the process that is carried out by green plants where they use energy from the sun together with carbon dioxide and water to form simple sugars such as glucose and also release oxygen as a by product.
-This can be shown by the reaction;
6 CO2 + 6 H2O → C6H12O6 + 6 O2
This indicates that six molecules of carbon dioxide are combining with six molecules of water to form glucose molecules C6H12O6, and six molecules of water.
The glucose formed is then stored in form of starch or used in cellular respiration where it is converted to ATP, a form of energy which is used by the cells to drive cellular processes such as growth and transport.
