Scientists use a system called Classification of Living Things, which categorizes each living organism into the following groups: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
The correct answer is C. The sepal
Explanation:
Plants reproduction includes different types of sexual and asexual reproduction. In the case of sexual reproduction that implies gametes of different plants being fused through fertilization, this occurs through different structures in flowers which are the reproductive structures in many plants. This includes the pistil that produces ovules and it is considered as the female organ in plants, the style, and stigma that are part of the pistil, the statement that contains pollen or male gametophyte and therefore is considered as the male organ and includes the anther and filament. However, the sepal is not part of this reproductive system as these are structures similar to leaves that are in the base of the flower and protect this before it opens or blossoms.
I am not really sure but you can get the answer from it :
They discovered a fundamental mechanism of how proteins protect chromosomes while DNA is being copied (a process called DNA replication), which relies on a protein called RPA. Cells have a limited amount of this protein, which they use as 'band aids' to protect the DNA temporarily during replication.
Answer:
<em>The correct option is C) The helicase enzyme unwind the DNA molecule into two strands.</em>
Explanation:
DNA replication occurs in a semi-conservative manner. This means that each strand of the DNA can give rise to a new strand. For the process of DNA replication to begin, firstly it is necessary that the DNA unwinds. Topoisomerases are enzymes which are known to remove the super-coiling of the DNA. Helicases can be described as the enzymes which separate the two strands of DNA from the region where replication has to begin. Hence, option C is correct.
The vertebrae form a column with a cavity called the vertebral canal.
A part of the central nervous system, the spinal cord is located inside this canal, so this canal is often called the spinal canal. Trough the openings in the canal the spinal nerves go to different parts of the body that they innervate.
