are phenols and glycosides induced or pre-existing defenses mechanisms for plants immunity ?
Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.
Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.
Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.
Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

How does the genetic code for an entire human being fit into the microscopic nucleus of a skin sell?
Answer:
The DNA of each chromosome is coiled, compacted, and coiled up some more.
Explanation:
Genetic code is the nucleotide sequence of DNA which is compacted to a chromosome to fit in the skin cell by the protein which compacts the long DNA into the small chromosome.
What is DNA organization?Levels of DNA Compaction nucleosomes, which resemble "beads on a string," are formed when double-stranded DNA is wrapped around histone proteins. A 30-nm chromatin fiber is formed from the nucleosomes.
The chromosomes narrow more during mitosis in a cell. In the S phase of interphase, DNA replication occurs. To create chromosomes, the chromatin fibers are further coiled and compressed.
Chromosome DNA is crammed into the eukaryotic nucleus little area by proteins. The resultant DNA-protein combination is known as chromatin, and these proteins are known as histones.

A. Specific heat values for solids will never vary for different ranges of temperature.
B. The specific heat of a gas can be measured at constant pressure.
C. Specific heat values for liquids will never vary for different ranges of temperature.
D. The specific heat of a gas can be measured at constant volume only.
When talking about specific heat, it is correct to say that a gas's specific heat may be determined at constant pressure. The correct option is B.
The amount of heat needed to increase a substance's temperature by 1 degree Celsius or Kelvin is known as its specific heat. The specific heat of a gas can be measured at constant pressure.
The specific heat for gases can be calculated at either constant volume or constant pressure. The heat capacity at constant pressure (Cp) and heat capacity at constant volume (Cv) are the terms used to describe the specific heat when measured at constant pressure and constant volume, respectively. For the majority of gases, Cp has a larger value than Cv.
