Typically, gametes are haploid cells. They only contain a portion of the chromosomes because as they intertwine with the meeting gamete the other half of the chromosome will ideally fit the other half of the cell and fertilization will occur. Moreover, when a sperm or egg cell has already a complete chromosome or is diploid no fertilization will happen.
Answer:
True, the Hypothalamus is linked between the nervous system and the endocrine system
Answer:
The correct answer is 'd' No, because Rhizbium radiobacter only infects wounded area of the plant and those regions are already dead.
Explanation:
Rhizobium is a genus of gram negative, soil bacteria that forms symbiotic relationship with certain plant, fixing nitrogen. However, soil borne plant pathogen, <em>Agrobacterium tumefaciens, </em>or rhizobium radiobacter, are tumor producing species that does not in anyway benefit the plant. The have a tendency to cause crown gall tumors by transfering T-DNA of its Ti plasmid intp a plant cell, where the T-DNA becomes integrated into the plant genome, Hence causing overproduction of plant growth hormones which ultimately results in tumor. A. tumefaciens does not elicit a typical Hypersensitivity response in a plant. As it enters only through wounds in the plant and these regions are already dead, hence no hypersensitivity response is produced by the plant.

What is RNA virus?</h3>
- Deoxyribose and ribose, respectively, are the names of the pentose sugars found in DNA and RNA.
- The presence of the hydroxyl group on the 2' carbon of ribose and its lack on the 2' carbon of deoxyribose distinguishes the sugars.
- While the sugar used to construct both DNA and RNA is named deoxyribose (left in the image), the sugar used to construct RNA is simply referred to as ribose.
- Ribose, a 5-carbon sugar, is present in RNA, whereas deoxyribose, a 5-carbon sugar, is present in DNA.
- Both kinds of sugar are crucial parts of nucleotides.
- Pentose sugars, which are a component of DNA, can be found in nucleic acid.
