Answer:
The alcohol group will have produced the greatest volume of urine
The concentrated salt solution group will have produced the least volume of urine
Explanation:
Alcohol inhibits the antidiuretic hormone. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, acording to the organism´s needs. The antidiuretic hormone is very sensitive to the presence of alcohol in the blood. Alcohol inhibits the hormone production and the kidneys eliminate more water than the necessary volume. In other words, alcohol is a diuretic substance that enhances urine production.
Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst and hence, water ingestion. It also causes an increase in the antidiuretic hormone, which anhances in water reabsorption by the kidneys in its collector tubules. Salt consumption causes a change in osmolarity, which drives to an increase in water reabsorption and an important reduction in urine volume.
Answer:
The last one. Plants make more sugar on sunny days than on cloudy days
Explanation:
The best answer is C.
When an individual suffers a bacterial infection in the legs, immune proteins called acute phase proteins bind to the surface of the bacteria by a process called opsonisation.
Opsonised bacteria are therefore coated with molecules (self antigens) that phagocytic cells recognize. Activated phagocytes engulf and destroy opsonized bacteria by "swallowing " (engulfing) them.
Inside the phagocyte, enzymes break down the bacteria onto small fragments just the way food is broken down by enzymes in the digestive system. Phagocytes then present the fragments on their surface which helps in the final destruction of the bacteria within the phagocyte.
Structure B looks like a strand of mRNA leaving the nucleus. So the answer would be B.
Answer:
The forestry department is using a<u> 1. </u><em><u>chemical method</u></em><u>.</u> This involves using a 2. <em><u>foliar spray</u></em> method, in which department personnel will spray directly on trees' leaves.
Explanation:
- White pine blister is a fungal disease of plant caused by fungus <em>Cronartium ribicola.</em>
- This fungus infects the plant through the stomata of the leaves.
- There are several methods of controlling pests and pathogen in agriculture which include ; mechanical methods; chemical methods and Biological methods.
- Mechanical methods include constructing barriers, electrical fencing etc.
- The biological method include introduction of organisms that will suppress pathogen activity.
- Chemical methods include use of pesticides , that are poisonous chemical substance that will kill the pathogen.
- Here the forestry department decides to spray insecticides thus, they are using a chemical method.
- Secondly they are going to spray the insecticide on each leaf so they have chosen the method of foliar spray and not the cut stump treatment or basal bark method.
