List and explain nonspecific immune defenses in plants found in a chaparral

1 answer:

6 0

Plants’ nonspecific immune responses includes cell-surface receptors (pattern recognition proteins) which allow them to identify certain patterns characteristic for pathogens. Activated receptors trigger the production of chemical signals that may initiate both local and systemic defense responses. Sometimes when a plant is affected by infection, it triggers rapid localized programmed cell death to stop the infection further. When it comes to defense form the herbivores, plants have physical barriers (plant cell walls and their extensions), some antibiotic compounds (phytoalexins), and even enzymes that can defend them.

Answer:

The eukaryotic cell nucleus. Visible in this diagram are the ribosome-studded double membranes of the nuclear envelope, the DNA (complexed as chromatin), and the nucleolus. Within the cell nucleus is a viscous liquid called nucleoplasm, similar to the cytoplasm found outside the nucleus.

Neporo4naja [7]

Answer:

<em>The correct option is B) undergo global warming at the same rate as we are seeing currently</em>

Explanation:

The Sun and the volcanoes play a great role in controlling our environment and climate even today. The quantity of the rays of the sun hitting the different parts of the Earth determines what the average weather or climate of a region would be. The volcanoes that erupt from the Earth have been a cause for global warming even today and will continue to raise the temperature of the Earth.

In 3-5 sentences write a description of how the 4 terms, DNA, chromosomes, genes and traits, are related and/or work together to

wel

Answer:

Please find the explanation below

Explanation:

Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.

The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.

Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
