Answer:
The oceans are present on the 70 percent of the world but only 5 percent of the total oceans are explored yet.
There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
Answer:
TAGTC
Explanation:
There are four different nucleotides in DNA: adenine, thymine, cytosine and guanine.
The bases pair like so:
A with T (adenine with thymine)
C with G (cytosine with guanine)
The DNA sequence given is :
ATCAG
Match As with Ts, Ts with As, Cs with Gs and Gs with Cs.
The sequence of nucleotides that would bond with the sequence above is:
TAGTC
Answer:
c. They lack lignified vascular tissue
Explanation:
We know that forest consists of tall trees. In the tall trees the water and minerals are transported to the every part of tree through the lignified vasucular tissue. This tissue not only helps in transport within the tree but also provides some sort of mechanical strength due to the presence of lignin it its walls. On the other hand bryophytes are non-vascular plants which means they lack vascular tissue and thus a mechanism for long distnace transport of water and minerals is absent in them. So they can't be taller as a tree and thus can't form forest.
versatile cas12k-based genetic engineering toolkit (c12kget)
- Genetic modification of micro-organisms is conducive to the selection of high production producers of high-value-added chemicals, but a deficient of genetic tools limits the industrialization of most wild species
- It is very important to develop host-independent gene editing tools which can be used for genetic modification deprived strains.
- A easily found Cas12k-based genetic engineering toolkit (C12KGET) that can result into genomic integration of small parts up to 10 kb in size with up to 100% efficiency in challenging strains.
- By using C12KGET, we accomplished the first example of highly efficient genome editing in Sinorhizobium meliloti, which was successfully solved the question of that industrial strains are difficult to genetically modify, and increased vitamin B12 production by 25%.
- Cas12k can be directly used for transcriptional regulation of genes with up to 92% efficiency due to its naturally inactivated nuclease domain
