<h2>Energy </h2>
Explanation:
Energy flows in only one direction through an ecosystem
- The Sun supports most of Earth's ecosystems
- Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
- The food energy created by producers is passed to consumers, scavengers, and decomposers
- Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
- Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
- So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
- Animals at the third level have only 10% as much available to them as those at the second level
Answer:
Zinc. (Ans. B)
Explanation:
Trace minerals: Trace minerals are defined as the inorganic molecules which are necessary for the human body for the different functions.
Zinc function in human metabolism is defined as a cofactor for numerous enzymes. Zinc play a role as a catalyst in a broad range of reactions. It is involved in the metabolic pathway directly or indirectly with lipids, carbohydrates, proteins, energy metabolism, and they are also important for the cell division process.
They also need for tissue and growth repair, and for reproductive development also. It's also played a vital role in immune system such as wound healing or required for the function and structure of the skin.
Answer: p (short hair) = 0.91 and q (long hair) = 0.09
Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.
For this question, short hair is allele L and long hair is allele l
So, the frequency of short hair is p and of long hair is q.
To calculate the frequencies:
Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)
p = 182/200 = 0.91
The same formula goes for the recessive allele, so:
q = 18/200 = 0.09
Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
