Answer:
Ovule becomes seed after fertilization and ovary becomes the fruit
The answer is Denitrification.
Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.
Answer:
Explanation:
All viruses have a capsid or head region that contains its genetic material. The capsid is made of proteins and glycoproteins. Capsid contruction varies greatly among viruses, with most being specialized for a particular virus's host organism. Some viruses, mostly of the type infecting animals, have a membranous envelope surrounding their capsid. This allows viruses to penetrate host cells through membrane fusion. The virus's genetical material rests inside the capsid; that material can be either DNA, RNA, or even in some cases a limited number of enzymes. The type of genetic material a virus contains is used in classification, and is discussed in Virus Classification.
In addition to the head region, some viruses, mostly those that infect bacteria, have a tail region. The tail is an often elaborate protein structure. It aids in binding to the surface of the host cell and in the introduction of virus genetic material to the host cell.
The ability of microtubules to undergo rapid <u>depolymerization </u>and slower<u> polymerization</u> is associated with the ability of the <u>spindle apparatus</u> to explore the cell and locate chromosomes.
<u>Explanation:</u>
Microtubules are tubulin polymers that make up part of the cytoskeleton and provide eukaryotic cells with framework and shape. These are formed by polymerizing the dimer into protofilaments of two globular proteins, alpha and beta tubulin, which can then be combined laterally to form the microtubule, a hollow tube.
Tubulin dimers can attach two GTP molecules, one of which may be hydrolyzed following assembly. Tubulin dimers are in GTP-bound state throughout polymerization. Once hydrolysis reaches to the peak of the microtubule, a rapid depolymerization and shrinkage is initiated.
