Marsha and Meghan drive to St. Louis to attend a Cardinals baseball game. Once inside the stadium, they decide to start drinking beer. After a few innings the young women find themselves frequently having to use the restroom, much to the annoyance of the other fans sitting around them that have to let them pass each time.
Required:
a. What hormone does the alcohol Marsha and Meghan are drinking appear to be inhibiting?
b. What is the normal action of this hormone?
Answer:
a.The alcohol is inhibiting the vasopressin hormone, also known as antidiuretic hormone (ADH).
b.The vasopressin hormone makes us retain water in our kidneys to maintain adequate water levels in our body and expel the right amount of water and other products in the urine.
Explanation:
When we drink alcohol, we inhibit the antidiuretic hormone(ADH), also called vasopressin hormone. It is responsible for the retention of water in our kidneys to absorb the products that are there. Also, it keeps the body with the right levels of liquid. If we drink alcohol, we inhibit the ADH, so we would not retain water, and as a result, we will produce more urine, which leads us to urinate more often. The consequence of this excessive loss of water is dehydration.

Answer:y = y = -5x + 2
Explanation:
Y = (y2-y1)(x2-x1) x + b = mx + b (b is the y-intercept)
= (-8+3)/(2-1)x + b = -5x + b
to find b
when x = 0, y=b = 2
(could draw graph to make clear)
this is a straight line: the slope shows that for any x0, y1 = y0 - 5

Question 1- Name 2 ways that humans affect land ecosystems.
Meat sharing can be considered an example of cooperation among primates. Which of the following is NOT a cooperative behavior observed among primates?
a. warning calls
b. nut cracking
c. grooming
d. group hunting
e. caring for a subadult by someone other than the mother
Answer:
e.
Explanation:
The correct answer would be caring for a subadult by someone other than the mother.
Cooperation or cooperative actions are those actions that are carried out by two or more individuals in order to achieve a common goal or goals.
Warning calls are carried out by one or two individuals in order to warn those around of a particular danger. Nut cracking among primates requires the collective efforts of many individuals. Grooming is a social behavior among primates that requires the cleaning up and maintenance of boy hygiene of an individual by another individual. Group hunting involves the collective efforts of a group of primates.
The only option that does not require cooperation is caring for a subadult by someone other than the mother.
The correct option is e.

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.
B. Megakaryocyte: Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.
C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies. Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.
D. Basophil: Granulosites. Immune System cells. in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.
E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.
F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections. Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.
G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.
H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments
I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.

What is actually cycled in a web of organisms?
Answer:
Carbondioxide gas.
Explanation:
Carbondioxide gas is actually cycled in a web of organisms, The plants takes carbondioxide gas for the process of photosynthesis, this plant is eaten by herbivores for energy and carbondioxide is released in the process of respiration. After that, carnivores feed on these herbivores and oxygen is used in the breakdown of food for releasing energy and carbondioxide gas is also released from the body through breathing so the cycle of carbondioxide gas is continue.
