The CRISPR-Cas system is widely found in bacterial and archaeal genomes as a defense mechanism against invading viruses and plasmids [1–6]. The type II CRISPR-Cas system from Streptococcus pyogenes relies on only one protein, the nuclease Cas9, and two noncoding RNAs, crRNA and tracrRNA, to target DNA [7]
Explanation:
This research could help determine how efficient energy and matter transfer is through the ecosystem. Currently, it is known that this transfer is very inefficient with a mere 10% energy transfer captured in biomass from one trophic level to another. Most of the energy is lost to the environment mainly as heat energy.
It is, therefore, critical that research determines ways of drastically enhance this efficiency so as to be able to colonise Mars. It will be required that whatever humans grow/rear on Mars in small modified fields translate into a high transfer of energy when consumed by humans. This makes it tenable to sustain humans on the distant planet.

The human eye is grief in damage of in-depth perception, color recognition, and peripheral vision. Judging speed and distance based on visual evidence is also more difficult in the dark. In addition, the darkness of night, and even the dimness of dusk and dawn.
Answer:
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form
Explanation:
Silicate Minerals. The first classification of minerals is silicate minerals.
Native Element Minerals. Native elements refer to minerals that only contain the atoms of one type of element.
Carbonate Minerals.
Halide Minerals.
Oxide Minerals.
Mineral nutrients for the human body include: iron, calcium, copper, sulfur, phosphorus, magnesium and many others. An archaic use of the word "mineral" comes from the Linnaean taxonomy in which all things can be assigned to the animal, vegetable, and mineral kingdoms.
Answer:
The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium. Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood. hope it helped
