Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses.
The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine.
Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.
Answer:
An oxbow lake forms when a river creates a meander, due to the river's eroding the bank. After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck during a flood, cutting off the meander and forming an oxbow lake.
The correct answer is option C
The frequency of the homozygous recessive genotype
In the Hardy-Weinberg equation, p is the frequency of the dominant allele, and q is the frequency of recessive allele then the frequency of genotype is represented by
p^2 = p x p = frequency of the homozygous dominant genotype ( AA)
q^2 = q x q = frequency of the homozygous dominant genotype (aa)
2 pq = p x q = The frequency of the heterozygous dominant genotype ( Aa)
<span>Epidermal cells of a plant leaf have a similar function to the skin system of a human. Their common function is protection. The epidermal cells provide coverage of the plant parts and protect it from damage. Also, the epidermal layer of leaves allow the exchange of water through transpiration and thus, maintains the temperature of the plant body. The same does the human skin system.</span>
<span>Stomata of the plants are structures similar to the function of the human respiratory system (lungs). <span>Plants use stomata (tiny “holes”) which let the carbon dioxide and oxygen in and out in a process called diffusion.</span></span>
