Answer:
The correct answer is option C.
Explanation:
The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.
The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.
These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.
Answer:
a fuel for cellular respiration and a starting material for making other organic molecules.
Explanation:
Plants have the ability to produce sugars by the process of photosynthesis. Plants can convert the inorganic CO2 from the air into the organic nutrients such as sugars. Plants store sugars so that they can serve as a source of ATP for the cells as and when required. The sugars enter the process of cellular respiration and are oxidized into CO2 and H2O. In addition, the energy of chemical bonds of the sugars is used to form ATP molecules.
Plants also use sugars to synthesize other organic molecules. For example, several intermediates of Kreb's cycle can serve as precursors for the synthesis of amino acids. Amino acids are joined together to form different proteins.
Answer:
All of them should be checked
Explanation:
If you make a punnet square you will have F and f lining the top and sides. The inside boxes will be FF, Ff, Ff, and ff. FF and Ff are long fins and ff is short fins so both are possible. Hope that helps good luck.
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The best answer is A.
The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids in each polypeptide chain which make up a protein.
The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.
The structure of the finished protein will depend largely on the first (primary) chain of amino acids to be produced to make up that protein.
