Answer:
B
Explanation:
The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.
In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.
If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)
However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.
Answer:
Explanation: Although cellular respiration has multiple parts, the basic chemical equation is:
Answer: Oxygen
Explanation: Oxygen + Glucose (sugar) = Carbon Dioxide + Water + Energy (ATP)
This equation is often broken into two parts, the reactants and the products. Reactants are the molecules that begin cellular respiration, in this case that would be oxygen and glucose. Products are what forms during cellular respiration. Here, the products are carbon dioxide, water, and energy. As the focus of this lesson is on the reactants of cellular respiration, oxygen and glucose, let's take a look at those.
Reactants--
The first reactant in the equation for cellular respiration is oxygen. Most people are familiar with oxygen since it's the primary gas needed for sustaining our lives. We obtain oxygen by simply breathing. Oxygen is highly reactive and therefore perfectly suited for driving chemical reactions such as cellular respiration. However, people may be less familiar with the second reactant in our respiration equation: glucose.
Answer:
Ans. (C).Progesterone promotes fertility because its levels rise during ovulation and immediately after.
Progesterone is a female sex-hormone, produced in the ovaries right after ovulation and its level rise immediately after ovulation (as shown in graph). A thick, and proper uterine lining is important for the implantation of zygote in the uterine wall.
Progesterone has the most influence on a secure pregnancy as it promotes the thickening and maintenance of uterine lining. Low levels of progesterone makes it difficult to get pregnant as zygote cannot implant properly.
The answer would be Haemoglobin.
The Haemoglobin is a red pigment found in RBCs of vertebrates that helps to transport oxygen to various tissues.
Vertebrate blood is bright red when it is oxygenated and dark red when it is deoxygenated. Some animals such as crustaceans or mollusks, use haemoglobin to carry oxygen instead of hemoglobin.
