The characteristics that most of the top hit sequences share are; They contain a ribosomal RNA (rRNA) sequence. Additionally, they contain a sequence of an internal transcribed spacer. The ribosome is a cellular machine found in all organism. It serves to convert the instructions found in messenger RNA into the chains of amino-acids that make up proteins. The ribosomes is responsible for the synthesis of proteins. Internal transcribed spacer refers to the spacer DNA situated between the small-subunit ribosomal RNA and large-subunit rRNA genes in the chromosome or the corresponding transcribed region in the polycistronic rRNA precursor transcript.
The correct answer is C. An ecosystem service
Explanation:
In ecology, an ecosystem service refers to processes or elements that are part of the natural environment but besides this represent benefits for humans, this includes organisms and processes involved in the decomposition of waste and also pollination. Pollination is an example of an ecosystem service because, in pollination insects, birds and other organism or even wind transfer pollen which makes possible plants fertilization and this is essential for crops in agriculture, which means humans benefit for pollination and therefore this is an ecosystem service.
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.
<span>Most organisms, including humans, can't use the free gaseous form of nitrogen found in the air. We need other organisms and natural processes to "fix" nitrogen into a solid form that plants and animals can use. Most of the nitrogen that plants and animals use is made by bacteria.</span>
Answer:
The difference between adaptation and natural selection is that adaptation is the characteristic while natural selection is the mechanism that increases the probability that an advantageous characteristic is passed on and becomes commonplace.
